Intravenous lidocaine is a promising complementary strategy for sedation during surgical procedures. We performed a systematic review and meta-analysis to compare intravenous lidocaine with placebo as an adjuvant to propofol-based sedation in patients undergoing colonoscopy.

We searched MEDLINE, Embase and Cochrane databases for randomised controlled trials comparing sedation with propofol and lidocaine vs. propofol and placebo in patients undergoing colonoscopy. The primary outcome was total propofol dose. A random-effects model was used to estimate the mean differences and risk ratios.

We included eight trials with 520 patients. Compared with placebo, intravenous lidocaine reduced propofol consumption during the procedure (mean difference (95%CI): -42.93 mg (-62.89 to -22.97)); shortened awakening time (mean difference (95%CI): -3.38 minutes (-5.92 to -0.84)); reduced post-procedural pain scores (mean difference (95%CI): -1.38 (-2.72 to -0.04)); and increased patient satisfaction scores (mean difference (95%CI): 0.50 (0.30 to 0.70)). There were no significant differences between the groups in procedure duration; endoscopist satisfaction scores; and risk of hypoxia or hypotension.

In patients undergoing colonoscopy, the addition of intravenous lidocaine to propofol-based sedation reduced propofol consumption, shortened awakening time, mitigated post-procedural pain and enhanced patient satisfaction compared with placebo. Although the findings are statistically significant, clinical relevance and cost-effectiveness are unclear.

This study aimed to report findings from EGD investigations in older adults with dyspepsia and identify factors associated with organic dyspepsia in this population. We conducted a retrospective cross-sectional study at a tertiary care center in Northern Thailand. Medical records of adults aged 50 years and older presenting with dyspepsia who underwent initial EGD between January 2018 and December 2022 were reviewed. Organic dyspepsia includes erosive esophagitis, ulcer, mass, and cancerous lesions. Multivariable logistic regression was used to identify factors associated with organic dyspepsia. Data from 466 patients were analyzed. Functional dyspepsia was the predominant diagnosis (94.0%), while organic dyspepsia was diagnosed in 6.0% of patients. Gastric/duodenal ulcer, erosive esophagitis, and gastric malignancy accounted for 1.9%, 1.7%, and 1.1% of cases, respectively. After adjustment for covariates, a low body mass index (BMI of less than 18.5 kg/m2) and male gender significantly increased the likelihood of organic dyspepsia, with an adjusted odds ratio (OR) of 4.34; 95% CI 1.45-12.09, p=0.009 and adjusted OR of 2.64; 95% CI 1.13-6.17, p=0.024, respectively. There were no significant associations found between other factors and organic dyspepsia, including age, smoking, alcohol use, symptom duration, H. pylori infection, and NSAID use.

Peptic ulcer disease (PUD) remains a significant yet poorly understood public health issue in Africa, despite its declining prevalence in Western countries. Studies from Africa report a highly variable burden, with the highest prevalence observed in West Africa and the lowest in Southern Africa. However, the overall burden of PUD in Africa, its patterns (duodenal ulcers, gastric ulcers, and coexisting ulcers), and its association with H. pylori infection remain unclear.

This review aims to systematically analyze the pooled prevalence and patterns of PUD in Africa through a systematic review and meta-analysis.

A systematic review and meta-analysis was conducted following the PRISMA checklist. We searched PubMed, Hinari, and Google Scholar, supplemented by Google and Yahoo search engines. Observational studies reporting the prevalence and patterns of PUD among the African population were included. Two independent reviewers extracted data and assessed study quality. Pooled prevalence estimates were calculated using a random-effects model, with heterogeneity assessed via the Cochrane Q test and I2 statistic.

A comprehensive analysis of 58 studies revealed a pooled prevalence of PUD in Africa at 15.2%. The most common ulcer pattern was DU at 10.2%, followed by GU at 5.8%, while 0.6% of cases had both types. Regional variations were observed, with West Africa having the highest prevalence (19%), followed by East Africa (15%), North Africa (12%), and Southern Africa (8%). Among individual countries, Ghana reported the highest prevalence (27%), followed by Ethiopia (19%) and Tanzania (16%). Furthermore, the pooled prevalence of PUD was 14% before 2010 and 15% in 2011 and later. Additionally, 57.1% of patients tested positive for Helicobacter pylori infection, with its prevalence reaching 76.4% among those diagnosed with PUD. Substantial heterogeneity was observed across most analyses, with I2 values exceeding 95% and p-values < 0.001.

The analysis revealed a significant burden of PUD in Africa, with DU being more common than GU. Regional disparities were observed, with the highest prevalence in West and East Africa. Over the past two decades, the burden has remained relatively stable, reflecting a concerning trend. H. pylori infection was also frequently diagnosed in individuals undergoing endoscopic examination. However, substantial heterogeneity was noted across studies, highlighting variability in reported prevalence.

The APAGE Position Statements aimed to provide guidance to healthcare practitioners on clinical practices aligned with climate sustainability.

A taskforce convened by APAGE proposed provisional statements. Twenty-two gastroenterologists from the Asian Pacific region participated in online voting and consensus was assessed through an anonymized and iterative Delphi process.

There were five sections that addressed the rationale for climate action, the importance of adopting principles of waste management, clinical practice, gastrointestinal endoscopy, and issues related to advocacy and research. Sixteen statements achieved consensus and included the following: 1. APAGE recommends adopting prompt measures to reduce the carbon footprint of clinical practice due to the importance of climate action and its health cobenefits. 5. APAGE recommends adherence to professional clinical guidelines to optimize clinical care delivery in gastroenterology and hepatology to avoid the environmental impact of unnecessary procedures and tests. 8. APAGE recommends an emphasis on health promotion, disease prevention, and appropriate screening and surveillance, when resources are available, to reduce the environmental impact of managing more advanced diseases that require more intensive resources. 12. APAGE recommends that technological advances in endoscopic imaging and artificial intelligence, when available, be used to improve the precision of endoscopic diagnosis to reduce the risk of missed lesions and need for unnecessary biopsies. 13. APAGE recommends against the routine use of single-use endoscopes.

The position statements provide guidance to healthcare practitioners on clinical practices in gastroenterology, hepatology, and endoscopy that promote climate sustainability.

Upper gastrointestinal endoscopy (UGIE) plays a crucial role in diagnosis of gastrointestinal pathology. Therefore, this systematic review and meta-analysis aimed to assess the indications and findings UGIE, while exploring their regional distribution and temporal trend across Africa.

Systematic Reviews and Meta-Analysis of pooled prevalence for various indications and endoscopic findings were analyzed from multiple studies in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.

Seventeen common indication were identified. Of these dyspepsia was the most prevalent indication 52.4%, followed by abdominal pain 17.4%, hematemesis 13.9%, and GERD symptoms 11.2%. Other indications included dysphagia 9.2%, vomiting 9.2, odynophagia 3.5%, and melena 6.2% were identified. Rare indications such as anemia 2.3%, weight loss 2.6% were also reported. Regarding endoscopic findings, thirty-one common findings were identified by UGIE. Gastritis (33.3%) was the most common findings followed by normal findings 21.8%, the third most common was PUD 15.1%, particularly duodenal ulcer (10%), gastric cancer 3.3% were also prevalent in stomach. Related to esophageal findings, GERD 9.6%, esophagitis 8.3%, esophageal varices 7.2% and esophageal cancer 6.1% were identified. Regional difference were apparent, with esophageal cancer prevalent in Eastern (10%) and Southern Africa (10%). Gastritis (45%) and GERD (18%) were more apparent and common in Northern Africa. Even though it is not significant, temporal trends showed an increase in prevalence of gastritis (26 to 36%) and esophagitis (6 to 10%) from 2000-2010 to 2011-2024.

Most UGIE indications resulted significant UGIT pathology. However, this analysis did not assess age, sex based indications and findings and their relationship among specific indications and UGIE findings. So, future analysis should focus on age and sex based difference in indications and findings, and explore their relationship among specific indication and corresponding UGIE findings.

Deep enteroscopy, encompassing push enteroscopy (PE) and balloon-assisted enteroscopy (BAE), has revolutionized the diagnosis and treatment of pediatric small bowel disorders. This review examines the evolving role of these techniques in managing conditions such as obscure gastrointestinal bleeding, Crohn's disease, polyposis syndromes, strictures, and small bowel tumors. While PE is effective for both diagnostic and therapeutic interventions in the proximal small bowel, its limited insertion depth has driven the adoption of BAE techniques. These include single-balloon enteroscopy (SBE) and double-balloon enteroscopy (DBE), which provide deeper and more comprehensive access. Both BAE modalities offer greater insertion depth and stability, enabling advanced therapeutic interventions such as polypectomy, stricture dilation, and hemostasis. Pediatric-specific data demonstrate high diagnostic yields for BAE, with comparable outcomes between SBE and DBE. These techniques have proven safe across diverse indications, though younger children may experience slightly higher complication rates due to anatomical considerations. Despite these advancements, challenges persist, including a limited evidence base in pediatrics, barriers to training, and the need for standardized protocols. Additionally, emerging innovations such as artificial intelligence offer opportunities to enhance diagnostic accuracy and procedural efficiency. Comparative analyses of PE, BAE, and capsule endoscopy are necessary to refine procedural selection and optimize outcomes in pediatric patients. Furthermore, structured pediatric training programs and simulation-based learning could address competency gaps, ensuring safe and effective application of these techniques. By addressing current research gaps, embracing technological advancements, and tailoring approaches to pediatric populations, deep enteroscopy can continue to transform the management of small bowel disorders in children.

Endoscopic gastric pouch plications (EGPP) have emerged as a novel approach for managing weight-related issues and postoperative complications following bariatric surgery. However, safety for these revisions remains limited. This study aims to evaluate the 30-day rate of serious complications and mortality associated with EGPP using the MBSAQIP database.  METHODS: A retrospective analysis of the MBSAQIP database from 2020 to 2022 was conducted, focusing on patients undergoing EGPP. The primary outcomes were 30-day serious complications and mortality.

The study included 1474 patients. Recurrent weight gain was the most common indication for EGPP (71.9%), followed by suboptimal initial weight loss (15.1%), dumping syndrome (5.5%), reflux (4.1%), gastrointestinal tract fistula (1.0%), and others (0.9%). The mean operative time was 41.2 ± 35.2 min, with a mean hospital stay of 0.4 ± 0.7 days. Postoperative complications included 30-day readmissions (3.1%), serious complications (3.3%), 30-day interventions (2.5%), bleeding (0.8%), and reoperations (0.4%). The mortality rate was 0%. Multivariable analysis identified GERD as an independent predictor of serious complications (OR 1.79, 95% CI 0.98 to 3.2, p = 0.05) when adjusting for various factors.

EGPP is an uncommon procedure with only 1474 cases reported, primarily indicated for weight recurrence. It appears to be a relatively safe alternative to surgical revision. However, further research is needed to assess its efficacy and compare it to corresponding surgical revisions.

Propofol has been widely used in bidirectional gastrointestinal endoscopy sedation; however, it frequently leads to cardiovascular adverse events and respiratory depression. Propofol target-controlled infusion (TCI) can provide safe sedation but may require higher dosages of propofol. On the contrary, etomidate offers hemodynamic stability.

To evaluate the effect of different dose etomidate added to propofol TCI sedation during same-visit bidirectional endoscopy.

A total of 330 patients from Fujian Provincial Hospital were randomly divided into three groups: P, 0.1EP, and 0.15EP. Patients in the P group received propofol TCI only, with an initial effect-site concentration of the propofol TCI system of 3.0 mg/mL. Patients in the 0.1EP and 0.15EP groups received 0.1 and 0.15 mg/kg etomidate intravenous injection, respectively, followed by propofol TCI.

Patients in the 0.15EP group had higher mean blood pressure after induction than the other groups (P group: 78 mmHg, 0.1EP group: 82 mmHg, 0.15EP group: 88 mmHg; P < 0.05). Total doses of propofol consumption significantly decreased in the 0.15EP group compared with that in the other groups (P group: 260.6 mg, 0.1EP group: 228.1 mg, 0.15EP group: 201.2 mg; P < 0.05). The induction time was longer in the P group than in the other groups (P group: 1.9 ± 0.7 minutes, 0.1EP group: 1.2 ± 0.4 minutes, 0.15EP group: 1.1 ± 0.3 minutes; P < 0.01). The recovery time was shorter in the 0.15EP group than in the other groups (P group: 4.8 ± 2.1 minutes, 0.1EP group: 4.5 ± 1.6 minutes, 0.15EP group: 3.9 ± 1.4 minutes; P < 0.01). The incidence of hypotension (P group: 36.4%, 0.1EP group: 29.1%, 0.15EP group: 11.8%; P < 0.01) and injection pain was lower in the 0.15EP group than in the other groups (P < 0.05). Furthermore, the incidence of respiratory depression was lower in the 0.15EP group than in the P group (P < 0.05). Additionally, the satisfaction of the patient, endoscopist, and anesthesiologist was higher in the 0.15EP group than in the other groups (P < 0.05).

Our findings suggest that 0.15 mg/kg etomidate plus propofol TCI can significantly reduce propofol consumption, which is followed by fewer cardiovascular adverse events and respiratory depression, along with higher patient, endoscopist, and anesthesiologist satisfaction.

Since inception in 1968, biliary endoscopic retrograde cholangiopancreatography (ERCP) has transformed into a highly effective, minimally invasive modality for the identification and treatment of a variety of biliary pathologies including benign, malignant, and iatrogenic diseases. The diagnostic role of ERCP has been largely replaced by high-quality imaging modalities including endoscopic ultrasound and magnetic resonance cholangiopancreatography. However, there continues to be significant demand for therapeutic procedures. This article reviews the general principles of ERCP, as well as common indications, contraindications, and potential adverse events with which endoscopists and referring physicians should be familiar.

Upper gastrointestinal (UGI) symptoms are among the common complaints among patients visiting health facilities. Because of the scarcity of gastrointestinal endoscopy services and gastroenterologists, the pattern of common upper gastrointestinal diseases has not been well studied in the study setting. This study aimed to determine the pattern of upper gastrointestinal diseases among patients undergoing esophagogastroduodenoscopy (EGD). An institution-based cross-sectional study was conducted at three hospitals in Asella town, southeast Ethiopia. A total of 279 study subjects were included in the study. Three-fourths (74%) of the study participants had abnormal endoscopic findings. The clinical indications for endoscopic examination were dyspepsia (32.6%), peptic ulcer disease (PUD) (27.2%), suspicion of gastric cancer (13.3%), and suspicion of esophageal cancer (11.5%). The abnormal endoscopic findings were esophageal cancer (10.4%), gastric cancer (10%), duodenal ulcer (DU) (9.3%), and gastritis (8.6%). The abnormal biopsy findings were esophageal cancer (7.5%), gastric adenocarcinoma (6.4%), and gastritis (3.9%). Dyspepsia, peptic ulcer disease, and suspicion of UGI malignancies were the most common clinical indications for endoscopic examination, while esophageal cancer and gastric cancer were the most common abnormal endoscopic findings. The most common abnormal biopsy results were esophageal squamous cell carcinoma and gastric adenocarcinoma. It is advised to have a high index of suspicion for esophageal cancer and gastric cancer for patients who present with alarming upper gastrointestinal symptoms in the study setting.

Rapid climate change or climate crisis is one of the most serious emergencies of the 21st century, accounting for highly impactful and irreversible changes worldwide. Climate crisis can also affect the epidemiology and disease burden of gastrointestinal diseases because they have a connection with environmental factors and nutrition. Gastrointestinal endoscopy is a highly intensive procedure with a significant contribution to greenhouse gas (GHG) emissions. Moreover, endoscopy is the third highest generator of waste in healthcare facilities with significant contributions to carbon footprint. The main sources of direct carbon emission in endoscopy are use of high-powered consumption devices (e.g. computers, anesthesia machines, wash machines for reprocessing, scope processors, and lighting) and waste production derived mainly from use of disposable devices. Indirect sources of emissions are those derived from heating and cooling of facilities, processing of histological samples, and transportation of patients and materials. Consequently, sustainable endoscopy and climate change have been the focus of discussions between endoscopy providers and professional societies with the aim of taking action to reduce environmental impact. The term "green endoscopy" refers to the practice of gastroenterology that aims to raise awareness, assess, and reduce endoscopy´s environmental impact. Nevertheless, while awareness has been growing, guidance about practical interventions to reduce the carbon footprint of gastrointestinal endoscopy are lacking. This review aims to summarize current data regarding the impact of endoscopy on GHG emissions and possible strategies to mitigate this phenomenon. Further, we aim to promote the evolution of a more sustainable "green endoscopy".

Iron deficiency is the most common extraintestinal sign of colonic neoplasia, including colorectal cancer (CRC) and other lower gastrointestinal pathology. Both upper endoscopy and colonoscopy is usually recommended in the work-up of patients with unexplained iron deficiency, particularly in men and postmenopausal women. As the incidence of early-onset CRC (age <50 years) rises in the United States, there is an increasing need to identify risk predictors to aid in the early detection of CRC. It remains unknown if serum ferritin (SF), and what specific threshold, can be used as a marker to stratify those at risk for CRC and other lower gastrointestinal pathology. In this current review of the literature, we aimed to review guidelines for diagnostic workup of colonic neoplasia in the setting of iron deficiency and examine the association and specific thresholds of SF and risk of CRC by age. Some of the published findings are conflicting, and conclusions specific to younger patients are limited. Though further investigation is warranted, the cumulative findings suggest that SF, in addition to considering the clinical context and screening guidelines, may have potential utility in the assessment of colonic neoplasia.

Neuroendocrine neoplasms (NEN) are heterogenous with an increasing incidence in recent years.

Overview on incidence, symptoms, diagnostics, grading, imaging and prognostic determinants, including factors having an impact on therapeutic management.

Review on current literature, including original articles, reviews, guidelines and expert opinions.

NEN are mainly located in the gastrointestinal tract and their incidence has increased in recent years, mainly due to improved diagnostics, e.g., cross-sectional imaging. Clinical characteristics include hormone excess syndromes (carcinoid syndrome). Laboratory markers such as chromogranin A are commonly used as part of routine diagnostics, followed by endoscopic and endosonographic procedures, which also allow biopsies to be obtained. Tumor spread can be determined by contrast-enhanced computed tomography/magnetic resonance imaging (CT/MRI) or somatostatin receptor (SSRT)-PET/CT (positron emission tomography). Prognostic factors include Ki67 index, type, and grading. Resection with curative intent is the therapy of choice. In a metastasized setting, SSRT-directed treatment approaches are favored, while in dedifferentiated NEN, conventional chemotherapy is needed.

A broad diagnostic armamentarium can be offered to NEN patients and the improved diagnostic procedures have most likely caused a raising incidence in recent years. Among others, prognostic factors are Ki67 and NEN subtypes; these clinical determinants also have an impact on patient management.

Egypt faces a significant public health burden due to chronic liver diseases (CLD) and peptic ulcer disease. CLD, primarily caused by Hepatitis C virus (HCV) infection, affects over 2.9% of the population nationwide, with regional variations. Steatotic liver disease is rapidly emerging as a significant contributor to CLD, especially in urban areas. Acid-related disorders are another widespread condition that can significantly impact the quality of life. These factors and others significantly influence the indications and findings of gastrointestinal endoscopic procedures performed in Egypt.

We aimed to evaluate the clinico-demographic data, indications, and endoscopic findings in Egyptian patients undergoing gastrointestinal endoscopic procedures in various regions of Egypt.

This study employed a retrospective multicenter cross-sectional design. Data was collected from patients referred for gastrointestinal endoscopy across 15 tertiary gastrointestinal endoscopy units in various governorates throughout Egypt.

5910 patients aged 38-63 were enrolled in the study; 75% underwent esophagogastroduodenoscopy (EGD), while 25% underwent a colonoscopy. In all studied patients, the most frequent indications for EGD were dyspepsia (19.5%), followed by hematemesis (19.06%), and melena (17.07%). The final EGD diagnoses for the recruited patients were portal hypertension-related sequelae (60.3%), followed by acid-related diseases (55%), while 10.44% of patients had a normally apparent endoscopy. Male gender, old age, and the presence of chronic liver diseases were more common in patients from upper than lower Egypt governorates. Hematochezia (38.11%) was the most reported indication for colonoscopy, followed by anemia of unknown origin (25.11%). IBD and hemorrhoids (22.34% and 21.86%, respectively) were the most prevalent diagnoses among studied patients, while normal colonoscopy findings were encountered in 18.21% of them.

This is the largest study describing the situation of endoscopic procedures in Egypt. our study highlights the significant impact of regional variations in disease burden on the utilization and outcomes of GI endoscopy in Egypt. The high prevalence of chronic liver disease is reflected in the EGD findings, while the colonoscopy results suggest a potential need for increased awareness of colorectal diseases.

Constipation is a significant sociomedical problem, which can be caused by various reasons. In the diagnostic approach to patients with constipation, the following data are usually sufficient: History, complete physical examination (including rectal examination), and additional diagnostic tests. A colonoscopy is not a necessary diagnostic method for all patients with constipation. However, if patients have alarm symptoms/signs, that suggest an organic reason for constipation, a colonoscopy is necessary. The most important alarm symptoms/signs are age > 50 years, gastrointestinal bleeding, new-onset constipation, a palpable mass in the abdomen and rectum, weight loss, anemia, inflammatory bowel disease, and family history positive for colorectal cancer. Most endoscopists do not like to deal with patients with constipation. There are two reasons for this, namely the difficulty of endoscopy and the adequacy of preparation. Both are adversely affected by constipation. To improve the quality of colonoscopy in these patients, good examination techniques and often more extensive preparation are necessary. Good colonoscopy technique implies adequate psychological preparation of the patient, careful insertion of the endoscope with minimal insufflation, and early detection and resolution of loops. Bowel preparation for colonoscopy often requires prolonged preparation and sometimes the addition of other laxatives.

Since its development, the use of endoscopic ultrasonography (EUS) in the pancreas and the biliary tract has become increasingly important. The accuracy of EUS varies depending on the experience of the endoscopist. Hence, quality control measures using appropriate indicators are required to reduce these variations. American Society for Gastrointestinal Endoscopy and European Society of Gastrointestinal Endoscopy have announced the EUS quality indicators. Here, we reviewed the quality indicators of the EUS procedure in the current published guidelines.

The rate of esophagogastric cancer is rising among individuals under 50 years of age. It remains unknown whether early-onset esophagogastric cancer represents a unique entity. This study investigated the clinical and molecular characteristics of early-onset and average-onset esophagogastric cancer .

We reviewed the Memorial Sloan Kettering Cancer Center gastric, esophageal, and gastroesophageal junction cancer database. Associations between baseline characteristics and tumor and germline molecular alterations were compared between those with early-onset and average-onset esophagogastric cancer using Fisher exact tests and the Benjamini-Hochberg method for multiple-hypothesis correction.

We included 1123 patients with early-onset esophagogastric cancer (n = 219; median age = 43 years [range = 18-49 years]) and average-onset esophagogastric cancer (n = 904; median age = 67 years [range = 50-94 years]) treated between 2005 and 2018. The early-onset group had more women (39% vs 28%, P = .002). Patients with early-onset esophagogastric cancer were more likely to have a gastric primary site (64% vs 44%, P < .0001). The signet ring cell and/or diffuse type was 3 times more common in the early-onset esophagogastric cancer group (31% vs 9%, P < .0001). Early-onsite tumors were more frequently genomically stable (31% vs 18%, P = .0002) and unlikely to be microsatellite instability high (2% vs 7%, P = .003). After restricting to adenocarcinoma and signet ring cell and/or diffuse type carcinomas, we observed no difference in stage (P = .40) or overall survival from stage IV diagnosis (median = 22.7 vs 22.1 months, P = .78).

Our study supported a preponderance of gastric primary disease sites, signet ring histology, and genomically stable molecular subtypes in early-onset esophagogastric cancer. Our findings highlight the need for further research to define the underlying pathogenesis and strategies for early detection and prevention.

Open-access oesophagogastroduodenoscopy (OAO) is defined as the performance of oesophagogastroduodenoscopy (OGD) requested by referring physicians without a prior specialist consultation. With the increasing demand for specialist appointments, the use of OAO has helped to reduce healthcare utilization by decreasing prior clinic visits. This also allows endoscopies to be scheduled and performed earlier. This study aims to evaluate our experience in providing OAO services to patients with non-alarming dyspepsia symptoms under the age of 60.

The records of patients scheduled for OAO from January 2019 to December 2022 at Singapore General Hospital (SGH) Department of Gastroenterology were analyzed.

Five hundred sixty-nine patients were scheduled for OAO, and 436 patients underwent the procedure. The mean age of patients was 45.7 (SD=10.9) years old. Thirty-six percent were males, and there were 80.8% Chinese, 5.3% Malay, 8.6% Indian, and 5.3% others. The median waiting time for endoscopy was 23 days (IQR 16-36), and no major adverse events were reported. Over half of the endoscopies were unremarkable (n=231, 53%). There were 25 (5.7%) patients with major findings; three had upper gastrointestinal adenocarcinoma (one oesophageal and two gastric), one had oesophageal varices, and 21 had peptic ulcer disease (10 gastric and 11 duodenal ulcers). A rapid urease test was conducted on 409 patients, and 55 (13.4%) were positive.

OAO is a safe and effective strategy for providing timely diagnostic OGD to normal-risk patients at our center. Primary care physicians are encouraged to refer non-alarming dyspepsia symptoms patients under 60 years for OAO over the conventional route.

Endoscopic retrograde cholangiopancreatography (ERCP) is an advanced endoscopic technique used to diagnose and treat biliary and pancreatic diseases. It is one of the most technically demanding endoscopic procedures. ERCP training programs must ensure trainees have adequate knowledge of the anatomy and physiology associated with biliopancreatic diseases. The variety of ERCP procedures included in training programs should provide sufficient basic training for novice trainees and advanced training for experienced endoscopists. The main endoscopic procedures should be trained in ascending order of difficulty. Incorporating models capable of simulating various clinical and anatomical conditions could provide an effective means of fulfilling training requirements, although they are not easily available due to expensive facilities and void of standard assessment. Competency assessment is crucial in ERCP training to ensure trainees can independently and safely perform ERCP. Because of the rapid advancement of diagnostic and therapeutic methods, postgraduate training is critical for ERCP practitioners. Once certificates are attained, practitioners are solely responsible for maintaining their competency, credentialing, and quality.

Helicobacter pylori (H. pylori) infection, a type I carcinogen, affects approximately 50% of the global population, correlating with various gastric pathologies. Notably, diagnostic sensitivities of non-invasive methods, such as the stool antigen test (HpSA), Serology, and Urea Breath Test (UBT), have been suggested to be less effective in older age groups. This study systematically reviews and meta-analyzes the diagnostic accuracy of these tests within the elderly population.

A comprehensive literature search was performed across multiple databases, including PubMed, Medline, and Web of Science, up to July 2023. Data were pooled and analyzed using random-effects models. Sensitivity, specificity, and Diagnostic Odds Ratios (DOR) were computed for the tests. Heterogeneity and risk of bias were assessed.

Eight studies involving diverse geographic locations and totaling between 46 and 1,441 participants per study were included. The pooled sensitivity and specificity for HpSA were 72.5 and 94.7%, for Serology 83.7 and 73.3%, and for UBT 96.4 and 88.3%, respectively. DOR for UBT, HpSA, and Serology were 94.5, 47.9, and 14.2, respectively. High levels of heterogeneity were observed across the studies.

UBT and HpSA proved effective for diagnosing H. pylori in those over 60, while serology showed lower specificity. Despite methodological variations in available studies, these non-invasive tests offer reliable alternatives, especially for older patients who recently undergone endoscopy or without an indication for it, warranting consideration by healthcare practitioners.

This study aimed to develop and validate a scoring system for predicting the need for esophagogastroduodenoscopy (EGD) in clinical practice to enhance accuracy and reduce misapplications.

From February 2021 to April 2022, outpatients scheduled for EGD at the Department of Gastroenterology in our hospital were recruited. Patients completed the system evaluation by providing clinical symptoms, relevant medical history, and endoscopic findings. Patients were randomly divided into the training and validation cohorts (at 2:1 ratio). The optimal algorithm was selected from five alternatives including a parallel test. Six physicians participated in a human-computer comparative validation. Sensitivity and negative likelihood ratio (-LR) were used as the primary indicators.

Altogether 865 patients were enrolled, with 578 in the training cohort and 287 in the validation cohort. The scoring system comprised 21 variables, including age, 13 typical clinical symptoms, and seven medical history variables. The parallel test was selected as the final algorithm. Positive EGD findings were reported in 54.5% of the training cohort and 62.7% of the validation cohort. The scoring system demonstrated a sensitivity of 79.0% in the training cohort and 83.9% in the validation cohort, with -LR being 0.627 and 0.615, respectively. Compared to physicians, the scoring system exhibited higher sensitivity (84.0% vs 68.7%, P = 0.02) and a lower -LR (1.11 vs 2.41, P = 0.439).

We developed a scoring system to predict the necessity of EGD using a parallel test algorithm, which was user-friendly and effective, as evidenced by single-center validation.

Our objective was to compare the safety and efficacy of Target-Controlled Infusion (TCI) versus intermittent bolus of propofol for colonoscopy sedation.

We conducted a randomized (1:1), single-blind, parallel-group superiority trial with fifty ASA I or II patients, both sexes, aged 18 to 65 years, Body Mass Index ≤ 30 kg.m-2, undergoing colonoscopy, allocated to receive propofol by TCI (effect-site, 2 μg.mL-1 plus 0.5 μg.mL-1 until unconsciousness and as necessary for agitation) or intermittent bolus (1 mg.kg-1 plus 0.5 mg.kg-1 every 5 minutes or as above). The primary safety outcome was the need for airway maneuvers and the primary efficacy outcome was the need for interventions to adjust the level of sedation. Secondary outcomes included incidence of agitation, propofol dose, and time to recovery.

The median (IQR) number of airway maneuvers and interventions needed to adjust sedation was 0 (0‒0) vs. 0 (0‒0) (p = 0.239) and 1 (0‒1) vs. 3 (1‒4) (p < 0.001) in the TCI and control groups, respectively. Agitation was more common in the intermittent bolus group ‒ 2 (0‒2) vs. 1 (0‒1), p < 0.001. The mean ± SD time to recovery was 4.9 ± 1.4 minutes in the TCI group vs. 2.3 ± 1.6 minutes in the control group (p < 0.001). The total propofol dose was higher in the TCI group (234 ± 46 µg.kg-1.min-1 vs. 195 ± 44 µg.kg-1.min-1 (p = 0.040)).

During colonoscopy, TCI is as safe as intermittent bolus of propofol while reducing the incidence of agitation and the need for dose adjustments. However, intermittent bolus administration was associated with lower total propofol dose and earlier recovery.

To date, the diagnostic test completion rate and the time to diagnostic endoscopy or colonoscopy among adults with iron-deficiency anemia (IDA) and/or hematochezia have not been well characterized.

To evaluate the diagnostic test completion rate and the time to diagnostic testing among veterans younger than 50 years with IDA and/or hematochezia.

This cohort study was conducted within the Veterans Health Administration between October 1, 1999, and December 31, 2019, among US veterans aged 18 to 49 years from 2 separate cohorts: those with a diagnosis of IDA (n = 59 169) and those with a diagnosis of hematochezia (n = 189 185). Statistical analysis was conducted from August 2021 to August 2023.

Diagnostic testing factors included age, sex, race and ethnicity, Veterans Health Administration geographic region, and hemoglobin test value (IDA cohort only).

Primary outcomes of diagnostic testing were (1) bidirectional endoscopy after diagnosis of IDA and (2) colonoscopy or sigmoidoscopy after diagnosis of hematochezia. The association between diagnostic testing factors and diagnostic test completion was examined using Poisson models.

There were 59 169 veterans with a diagnosis of IDA (mean [SD] age, 40.7 [7.1] years; 30 502 men [51.6%]), 189 185 veterans with a diagnosis of hematochezia (mean [SD] age, 39.4 [7.6] years; 163 690 men [86.5%]), and 2287 veterans with IDA and hematochezia (mean [SD] age, 41.6 [6.9] years; 1856 men [81.2%]). The cumulative 2-year diagnostic workup completion rate was 22% (95% CI, 22%-22%) among veterans with IDA and 40% (95% CI, 40%-40%) among veterans with hematochezia. Veterans with IDA were mostly aged 40 to 49 years (37 719 [63.7%]) and disproportionately Black (24 480 [41.4%]). Women with IDA (rate ratio [RR], 0.42; 95% CI, 0.40-0.43) had a lower likelihood of diagnostic test completion compared with men with IDA. Black (RR, 0.65; 95% CI, 0.62-0.68) and Hispanic (RR, 0.88; 95% CI, 0.82-0.94) veterans with IDA were less likely to receive diagnostic testing compared with White veterans with IDA. Veterans with hematochezia were mostly White (105 341 [55.7%]). Among veterans with hematochezia, those aged 30 to 49 years were more likely to receive diagnostic testing than adults younger than 30 years of age (age 30-39 years: RR, 1.15; 95% CI, 1.12-1.18; age 40-49 years: RR, 1.36; 95% CI, 1.33-1.40). Hispanic veterans with hematochezia were less likely to receive diagnostic testing compared with White veterans with hematochezia (RR, 0.96; 95% CI, 0.93-0.98).

In the cohorts of veterans younger than 50 years with IDA and/or hematochezia, the diagnostic test completion rate was low. Follow-up was less likely among female, Black, and Hispanic veterans with IDA and Hispanic veterans with hematochezia. Optimizing timely follow-up across social and demographic groups may contribute to improving colorectal cancer outcomes and mitigate disparities.

The coronavirus disease 2019 (COVID-19) outbreak has significantly modified hospital and outpatient activities.

To assess the pandemic's impact on the appropriateness of outpatient gastrointestinal (G.I.) endoscopy in a southern Italy Region.

Between 1 January 2019 and 31 December 2022, we compared the number, the type of activities, and the appropriateness of the G.I. endoscopy procedures in the four territorial gastroenterology and digestive endoscopy services of the Apulia region.

In 2019, 11 173 outpatient procedures were provided, which dropped by about 44% (P < 0.05) during 2020. The endoscopic activity was slightly reduced during 2020 (-18.77%), while every other activity dropped significantly. During 2021-2022, the overall activities slightly increased but remained below the number of activities provided before the pandemic (P < 0.05). However, the endoscopic activity increased by +6.86% from 2019 to 2022, mainly due to more colonoscopies. During the 4 years analysed, the overall appropriateness rate of the endoscopic examinations increased during 2020 (2019: 67%; 2020: 81%) while dropping again in the following years (2021: 75%; 2022; 69%).

The appropriateness of the G.I. endoscopic procedures in the territorial gastroenterology services in the Apulia Region has improved during the acute phase of the COVID-19 pandemic, dropping again in the following years. Overall, the appropriateness of endoscopic procedures remains suboptimal; thus, educational activities are needed to improve the appropriateness rate to optimise the limited resources.

Esophagogastroduodenoscopy (EGD) appropriateness in Open-Access System (OAS) is a relevant issue. The Gastropack Access System (GAS) is a new system to access gastroenterological services, based on the partnership between Gastroenterologists and GPs. This study aims to evaluate if GAS is superior to OAS in terms of EGDS appropriateness. Secondarily, we evaluated the diagnostic yield of EGDS according to ASGE guidelines. The GAS was developed in an area of Bologna where General Practitioners (GPs) could decide to directly prescribe EGDS through OAS or referring to GAS, where EGDS can be scheduled after contact between GPs and specialists sharing a patient's clinical information. Between 2016 and 2019, 2179 cases (M:F = 861:1318, median age 61, IQR 47.72) were referred to GAS and 1467 patients (65%) had a prescription for EGDS; conversely, 874 EGDS were prescribed through OAS (M:F = 383:491; median age 58 yrs, IQR 45.68). Indication was appropriate in 92% in GAS (1312/1424) versus 71% in OAS (618/874), p < 0.001. The rate of clinically significant endoscopic findings (CSEF) was significantly higher in GAS (49% vs. 34.8%, p < 0.001). Adherence to ASGE guidelines was not related to CSEF; however, surveillance for pre-malignant conditions was independently related to CSEF. All neoplasm were observed in appropriate EGD. GAS is an innovative method showing extremely high rates of appropriateness. ASGE guidelines confirmed their validity for cancer detection, but their performance for the detection of other conditions needs to be refined.

Introduction: Endoscopic procedures are performed more frequently in children due to technological advances that can be safely performed in an adequate setting with a support of a multidisciplinary team. Pediatric indications for ERCP (endoscopic retrograde cholangiopancreatography) and EUS (endoscopic ultrasound) occur mainly due to congenital malformations. In a pediatric case series, we report the application of EUS combined with duodenoscopy, eventually associated with ERCP and minimally invasive surgery, highlighting the importance of defining a tailored dedicated management pathway for each patient. Patients and methods: A series of 12 patients, managed at our Center in the last three years, were evaluated, and their management was discussed. Results: EUS was performed in eight patients and permitted the differential diagnosis of duplication cysts and the visualization of the biliary tree and pancreatic anatomy. ERCP was attempted in five patients: in one case, it permitted the preservation of pancreatic tissue, postponing surgery and in three patients, it was technically unfeasible. MIS (minimally invasive surgery) was performed in seven patients, two with laparoscopic common bile duct exploration (LCBDE). Precise anatomical definition and the possibility of surgical simulation and team sharing were evaluated under VR HMD (Virtual Reality Head Mounted Display) in four cases. Conclusions: Exploration of the common bile duct in children differs from that of the adult population and combines echo-endoscopy and ERCP. The integrated use of minimally invasive surgery in the pediatric area is necessary for the whole management perspective in complex malformations and small patients. The introduction in the clinical practice of a preoperative study with Virtual Reality allows a better survey of the malformation and a tailored treatment.

Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic biliary drainage (PTBD) are currently first- and second-line therapeutic options, respectively, for the relief of biliary obstruction. In recent years, however, endoscopic ultrasound-guided biliary drainage (EUS-BD) has become an established alternative therapy for biliary obstruction. There are multiple different techniques for EUS-BD, which can be distinguished based on the access point within the biliary tree (intrahepatic versus extrahepatic) and the location of stent placement (transenteric versus transpapillary). The clinical and technical success rates of biliary drainage for EUS-BD are similar to both ERCP and PTBD, and complication rates are favorable for EUS-BD relative to PTBD. As EUS-BD becomes more widely practiced and endoscopic tools continue to advance, the outcomes will likely improve, and the breadth of indications for EUS-BD will continue to expand.

The quality and safety of gastrointestinal endoscopy varies considerably across regions and facilities worldwide. In this field, quality management has traditionally focused on individual performance of endoscopists, with most indicators addressing process measures and limited evidence of improvement in health outcomes. Indicators of quality can be classified according to their nature and sequence. The various professional societies and organizations have proposed many systems of indicators, but a universal system is necessary so that healthcare professionals are not overburdened and confused with a variety of quality improvement approaches. In this paper, we propose guidelines by the Saudi Gastroenterology Association pertaining to quality in endoscopic procedures aiming to improve the awareness of endoscopy unit staff toward important quality indications to enhance and standardize quality of care provided to our patients.

Patients undergo colonoscopies for colorectal cancer screening and for the evaluation of gastrointestinal symptoms. Analysis of large administrative databases has demonstrated that some patients undergo repeat colonoscopies at intervals inconsistent with current recommendations, but these studies do not provide patient-level details. The medical records of 110 patients undergoing repeat colonoscopies within 1 year of their index colonoscopies at a tertiary care hospital-based endoscopy center were retrospectively reviewed to determine patient demographics, gastrointestinal symptoms, and endoscopic findings. Thirty-five patients had poor bowel preparations, and 11 patients had a history of colorectal cancer. Thirty-four patients had polyps identified during their index colonoscopies, and 28 patients had no polyps identified during their index colonoscopies. Eleven patients in the nonpolyp group had new endoscopic findings identified during the repeat colonoscopies. Twenty patients who had polyps identified on their index colonoscopies had 44 polyps identified on repeat colonoscopies. Repeat colonoscopies within 1 year occurred relatively infrequently in this endoscopy center. Indications included poor bowel preparation with incomplete studies, colonic polyps with incomplete resection, multiple polyps resulting in the possibility of missed polyps, and new gastrointestinal symptoms.

Background: Helicobacter pylori (Hp) persistent infection is an important pathogenic factor for a series of chronic gastric diseases from chronic gastritis to gastric cancer. Genetic and epigenetic abnormalities of microRNAs may play a vital role in the pathological evolution of gastric mucosa in Helicobacter pylori-related gastric diseases (HPGD). This study aimed to investigate the relationship between miR-146a, miR-196a2, miR-149, miR-499 and miR-27a gene single nucleotide polymorphisms (SNPs) and their expressions with pathological changes in gastric mucosa, and to further analyze the interactions between SNPs and Hp. Methods: Subjects in this study included patients diagnosed with HPGD and healthy controls. MiR-146a rs2910164, miR-196a2 rs11614913, miR-149 rs2292832, miR-499 rs3746444 and miR-27a rs895819 were genotyped by direct sequencing. Fluorescence quantitative PCR was used to detect microRNA expressions. Gene-gene and gene-environment interactions were evaluated by multifactor dimensionality reduction (MDR) method. Results: we found that frequency distribution of miR-196a2 rs11614913 CT genotype in gastric precancerous lesion (GPL) group and gastric cancer (GC) group was significantly higher than normal control (NOR) group [adjusted OR = 6.16, 95%CI (1.46-26.03); adjusted OR = 11.83, 95%CI (1.65-84.72), respectively]. CT genotype and C allele of miR-27a rs895819 were associated with increased risk of GC [adjusted OR = 10.14, 95%CI (2.25-45.77); adjusted OR = 3.71, 95%CI(1.46-9.44), respectively]. The MDR analysis results showed that the interaction between miR-196a2 rs11614913 and Hp was associated with the risk of GPL (p = 0.004). Meanwhile, the expression level of miR-196a2 in GC group was significantly higher than NOR, chronic inflammation (CI) and early precancerous lesion (EPL) groups among Hp-positive subjects. And expressions of miR-499 and miR-27a in GC group were both higher than EPL group. Also, miR-27a expression in GC group was higher than CI and gastric atrophy (GA) groups. Conclusion: miR-196a2 rs11614913 and miR-27a rs895819 may affect the genetic susceptibility to GPL or GC. MiR-196a2 rs11614913 and Hp have a synergistic effect in the occurrence and development of GPL. The up-regulation of miR-499, miR-196a2 and miR-27a expression caused by Hp infection may be an important mechanism of gastric carcinogenesis.

Upper gastrointestinal (GI) malignancy is a leading cause of cancer-related morbidity and mortality. Upper endoscopy has an established role in diagnosing and staging upper GI cancers, screening for pre-malignant lesions, and providing palliation in cases of advanced malignancy. New advances in endoscopic techniques and technology have improved diagnostic accuracy and increased the therapeutic potential of upper endoscopy. We aim to describe the different types of endoscopic technology used in cancer diagnosis, summarize the current guidelines for endoscopic diagnosis and treatment of malignant and pre-malignant lesions, and explore new potential roles for endoscopy in cancer therapy.

Climate crisis is dramatically changing life on earth. Environmental sustainability and waste management are rapidly gaining centrality in quality improvement strategies of healthcare, especially in procedure-dominant fields such as gastroenterology and digestive endoscopy. Therefore, healthcare interventions and endoscopic procedures must be evaluated through the 'triple bottom line' of financial, social, and environmental impact. The purpose of the paper is to provide information on the carbon footprint of gastroenterology and digestive endoscopy and outline a set of measures that the sector can take to reduce the emission of greenhouse gases while improving patient outcomes. Scientific societies, hospital executives, single endoscopic units can structure health policies and investment to build a "green endoscopy". The AIGO study group reinforces the role of gastrointestinal endoscopy professionals as advocates of sustainability in digestive endoscopy. The "green endoscopy" can shape a more sustainable health service and lead to an equitable, climate-smart, and healthier future.

Capsule endoscopy (CE) and deep enteroscopy (DE) can be useful for diagnosing and treating suspected small-bowel disease. Guidelines and detailed recommendations exist for the use of CE/DE, but comprehensive quality indicators are lacking. The goal of this task force was to develop quality indicators for appropriate use of CE/DE by using a modified RAND/UCLA Appropriateness Method.

An expert panel of 7 gastroenterologists with diverse practice experience was assembled to identify quality indicators. A literature review was conducted to develop a list of proposed quality indicators applicable to preprocedure, intraprocedure, and postprocedure periods. The panelists reviewed the literature; identified and modified proposed quality indicators; rated them on the basis of scientific evidence, validity, and necessity; and determined proposed performance targets. Agreement and consensus with the proposed indicators were verified using the RAND/UCLA Appropriateness Method.

The voting procedure to prioritize metrics emphasized selecting measures to improve quality and overall patient care. Panelists rated indicators on the perceived appropriateness and necessity for clinical practice. After voting and discussion, 2 quality indicators ranked as inappropriate or uncertain were excluded. Each quality indicator was categorized by measure type, performance target, and summary of evidence. The task force identified 13 quality indicators for CE and DE.

Comprehensive quality indicators have not existed for CE or DE. The task force identified quality indicators that can be incorporated into clinical practice. The panel also addressed existing knowledge gaps and posed research questions to better inform future research and quality guidelines for these procedures.

A liver abscess (LA) is the most common type of visceral abscess. While biliary tract disorders are its most common etiology, clinicians should also consider less frequent causes such as iatrogenic complications due to certain interventions. One of these unusual causes is related to endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (ES), a usually safe procedure that carries some risk of complications. We present the case of a 71-year-old female with a history of choledocholithiasis who underwent ERCP with ES without any immediate complications; she was discharged after 24 hours and readmitted three days later to the emergency room with fever and abdominal pain. An abdominal CT showed a liver abscess. Blood cultures were positive for Escherichia coli, Streptococcus anginosus, and Enterococcus faecalis, and the patient was started on directed antibiotic therapy with ampicillin, benzylpenicillin, and metronidazole. On day 17, due to hematochezia with hemodynamic instability, an urgent upper gastrointestinal endoscopy was performed, which revealed late post-ES bleeding, refractory to conventional endoscopic therapy. An ERCP was performed to control the bleeding by using a biliary fully covered self-expandable metal stent (FCSEMS), which was removed four weeks later. The follow-up CT showed a significant reduction of LA and the patient was discharged. This case highlights the association of two uncommon complications of ERCP: a LA and a major late post-ES bleeding. Clinicians should maintain a high index of suspicion for these complications in daily practice.

The incidence of early-onset (EO) GI cancers occurring in individuals younger than age 50 years has been rising at an alarming rate over the past two decades. Although this rise in incidence among young patients correlates with increased rates of obesity, changes in diet, and alterations in the environment, the effects of these environmental factors on carcinogenesis, metastasis, and treatment response are unknown. Although several unique clinical trends exist among EO-GI cancers and their average-onset GI cancer counterparts, GI cancers are molecularly indistinct between younger and older patients, and no data support distinct treatment paradigms for patients with EO disease. The majority of EO-GI cancers are not explained by germline changes. There remains a critical need for further research to understand the pathogenesis and optimal management of EO-GI cancers. In addition, current screening strategies are not adequate to identify EO-GI cancers, and early biomarkers are needed. Specialized centers, with a focus on psychosocial aspects of cancer management, can address the unique care needs of patients with EO-GI cancers.

The promotion of quality and best practices in gastroenterology and endoscopy is an ongoing effort. For upper GI endoscopy, quality indicators derived from clinical studies and expert consensus have been long established but remain variably obtained. To date, data on interventions aimed to improve these indicators are scarce. We systematically reviewed the literature to identify interventions and measures demonstrated to improve the performance of previously established upper endoscopy quality indicators. We also identified evidence gaps and opportunities for improvement in this area.
