Abstract
Ethnic health disparity is a well-acknowledged issue in many disease settings, but not diseases of the exocrine pancreas. A systematic review and meta-analysis was conducted to explore the race- and ethnicity-specific burden of diseases of the exocrine pancreas. Studies that compared health-related endpoints between two or more ethnicities were eligible for inclusion. Proportion meta-analyses were conducted to compare burden between groups. A total of 42 studies (24 on pancreatic cancer, 17 on pancreatitis, and one on pancreatic cyst) were included in the systematic review, of which 19 studies were suitable for meta-analyses. The incidence of pancreatic cancer was 1.4-fold higher among African-Americans, while the incidence of acute pancreatitis was 4.8-fold higher among an indigenous population (New Zealand Māori) compared with Caucasians. The prevalence of post-pancreatitis diabetes mellitus was up to 3.0-fold higher among certain ethnicities, including Asians, Pacific Islanders, and indigenous populations compared with Caucasians. The burden of diseases of the exocrine pancreas differs between ethnicities, with African-Americans and certain indigenous populations being at the greatest risk of developing these diseases. Development of race- and ethnicity-specific screening as well as protocols for lifestyle modifications may need to be considered with a view to reducing the disparities in burden of diseases of the exocrine pancreas.

The Use of International Classification of Diseases Codes to Identify Patients with Pancreatitis: A Systematic Review and Meta-analysis of Diagnostic Accuracy Studies. Clin Transl Gastroenterol 2018; 9:191. [PMID: 30287807 PMCID: PMC6172207 DOI: 10.1038/s41424-018-0060-1] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2018] [Accepted: 09/06/2018] [Indexed: 02/06/2023] Open
Abstract
Background Hospital discharge codes are increasingly used in gastroenterology research, but their accuracy in the setting of acute pancreatitis (AP) and chronic pancreatitis (CP), one of the most frequent digestive diseases, has never been assessed systematically. The aim was to conduct a systematic literature review and determine accuracy of diagnostic codes for AP and CP, as well as the effect of covariates. Methods Three databases (Pubmed, EMBASE and Scopus) were searched by two independent reviewers for relevant studies that used International Classification of Disease (ICD) codes. Summary estimates of sensitivity, specificity and positive predictive value were obtained from bivariate random-effects regression models. Sensitivity and subgroup analyses according to recurrence of AP and age of the study population were performed. Results A total of 24 cohorts encompassing 18,106 patients were included. The pooled estimates of sensitivity and specificity of ICD codes for AP were 0.85 and 0.96, respectively. The pooled estimates of sensitivity and specificity of ICD codes for CP were 0.75 and 0.94, respectively. The positive predictive value of ICD codes was 0.71 for either AP or CP. It increased to 0.78 when applied to incident episode of AP only. The positive predictive value decreased to 0.68 when the ICD codes were applied to paediatric patients. Conclusion Nearly three out of ten patients are misidentified as having either AP or CP with the indiscriminate use of ICD codes. Limiting the use of ICD codes to adult patients with incident episode of AP may improve identification of patients with pancreatitis in administrative databases.

Abstract
Acute pancreatitis (AP) is the most common pancreatic disease and consists of an acute inflammation of the pancreas. AP can contribute to endocrine and exocrine insufficiencies in survivors as a result of the key role of the pancreas in both glucose metabolism and nutritional digestion. The aim of this population-based study was to determine the endocrine or exocrine insufficiencies in patients after initial AP with biliary or alcohol-associated causes.We conducted a nationwide cohort study using data from Taiwan's National Health Insurance Research Database collected between 2001 and 2010. A total of 12,284 patients with AP were identified.Alcohol-associated AP (odds ratio, 1.894; 95% CI, 1.520-2.268; P < 0.001) and ≥2 admissions for AP (odds ratio, 1.937; 95% CI, 1.483-2.391; P < 0.001) were significantly associated with newly diagnosed diabetes mellitus after AP. Further, only alcohol-associated AP (odds ratio, 1.215; 95% CI, 1.133-1.297; P < 0.001) was significantly associated with pancreatic exocrine insufficiency after AP. Additionally, alcohol-associated AP (odds ratio, 1.804; 95% CI, 1.345-2.263; P < 0.001) and ≥2 readmissions for AP (odds ratio, 3.190; 95% CI, 2.317-4.063; P < 0.001) were significantly associated with both exocrine and endocrine insufficiencies after AP.Our data showed that alcohol-associated AP, rather than a biliary cause, contributed to a higher extent to exocrine or endocrine insufficiencies. Furthermore, recurrent AP also led to endocrine insufficiency.

Abstract
AIM: To determine the risk factors for gallstone-related biliary events.
METHODS: This retrospective cohort study evaluated magnetic resonance cholangiopancreatography images from 141 symptomatic and 39 asymptomatic gallstone patients who presented at a single tertiary hospital between January 2005 and December 2012.
RESULTS: Logistic regression analysis showed significant differences between symptomatic and asymptomatic patients with gallstones in relation to the number of gallstones, the angle between the long axis of the gallbladder and the cystic duct, and the cystic duct diameter. Multivariate analysis showed that the number of gallstones (OR = 1.27, 95%CI: 1.03-1.57; P = 0.026), the angle between the long axis of the gallbladder and the cystic duct (OR = 1.02, 95%CI: 1.00-1.03; P = 0.015), and the diameter of the cystic duct (OR = 0.819, 95%CI: 0.69-0.97; P = 0.018) were significantly associated with biliary events. The incidence of biliary events was significantly elevated in patients who had the presence of more than two gallstones, an angle of > 92° between the gallbladder and the cystic duct, and a cystic duct diameter < 6 mm.
CONCLUSION: These findings will help guide the treatment of patients with asymptomatic gallstones. Clinicians should closely monitor patients with asymptomatic gallstones who exhibit these characteristics.

Abstract
Acute pancreatitis is an inflammatory disease that is mild and self-limiting in about 80% of cases. However, severe necrotizing disease still has a mortality of up to 30%. Differentiated multimodal treatment concepts are needed for these patients, including a multidisciplinary team (intensivists, gastroenterologists, interventional radiologists, and surgeons). The primary therapy is supportive. Patients with infected pancreatic necrosis who are septic undergo interventional or surgical treatment, ideally not before the fourth week after onset of symptoms. This article reviews the pathophysiologic mechanisms of acute pancreatitis and describes clinical pathways for diagnosis and management based on the current literature and guidelines.

Abstract
Acute pancreatitis is a common disease most frequently caused by gallstone disease or excess alcohol ingestion. Diagnosis is usually based on characteristic symptoms, often in conjunction with elevated serum pancreatic enzymes. Imaging is not always necessary, but may be performed for many reasons, such as to confirm a diagnosis of pancreatitis, rule out other causes of abdominal pain, elucidate the cause of pancreatitis, or to evaluate for complications such as necrosis or pseudocysts. Though the majority of patients will have mild, self-limiting disease, some will develop severe disease associated with organ failure. These patients are at risk to develop complications from ongoing pancreatic inflammation such as pancreatic necrosis, fluid collections, pseudocysts, and pancreatic duct disruption. Validated scoring systems can help predict the severity of pancreatitis, and thus, guide monitoring and intervention.Treatment of acute pancreatitis involves supportive care with fluid replacement, pain control, and controlled initiation of regular food intake. Prophylactic antibiotics are not recommended in acute pancreatitis if there is no evidence of pancreatic infection. In patients who fail to improve, further evaluation is necessary to assess for complications that require intervention such as pseudocysts or pancreatic necrosis. Endoscopy, including ERCP and EUS, and/or cholecystectomy may be indicated in the appropriate clinical setting. Ultimately, the management of the patient with severe acute pancreatitis will require a multidisciplinary approach.

Abstract
Acute pancreatitis is an acute inflammatory disease of the pancreas which can lead to a systemic inflammatory response syndrome with significant morbidity and mortality in 20% of patients. Gallstones and alcohol consumption are the most frequent causes of pancreatitis in adults. The treatment of mild acute pancreatitis is conservative and supportive; however severe episodes characterized by necrosis of the pancreatic tissue may require surgical intervention. Advanced understanding of the pathology, and increased interest in assessment of disease severity are the cornerstones of future management strategies of this complex and heterogeneous disease in the 21st century.

Abstract
INTRODUCTION Cholecystectomy in cases of "warning" episodes of biliary colic may prevent biliary pancreatitis. We aimed to determine which proportion of patients with biliary pancreatitis, compared to other complicated and uncomplicated symptomatic gallstone disease, experienced "warning" episodes of colic and why these episodes did not lead to early cholecystectomy. PATIENTS AND METHODS One hundred seventy-five patients with complicated gallstone disease [pancreatitis (n = 53), symptomatic common bile duct (CBD) stones (n = 64), and acute cholecystitis (n = 58)] and 175 patients with symptomatic uncomplicated gallstones were interviewed at admission. RESULTS Fifty-seven percent (100 of 175) of patients with complicated disease (95% confidence interval = 50-65%) experienced "warning" episodes of biliary colic (pancreatitis 58%, CBD stones 67%, cholecystitis 45%) vs 96% (164 of 175) in uncomplicated disease. Eighty-seven percent of patients with "warning" episodes and complicated disease experienced patient's and general practitioner's delays. General practitioner's delay was more frequent if pain was located in the epigastric region compared to the right upper quadrant (51% vs 38%, P = 0.03). CONCLUSIONS Half of patients with biliary pancreatitis experience "warning" episodes of biliary colic, similar to other gallstone complications. In symptomatic patients, complications are often not prevented because of significant delays in diagnosis and treatment.

Abstract
Alcohol-associated acute and chronic pancreatitis occur in a minority of alcohol users, suggesting that most drinkers are protected from pancreatic diseases while a subset is susceptible. Ongoing studies suggest that the pathophysiology is complex and can involve multiple genetic and environmental pathways and stochastic events. Both rat models and human genetic epidemiology studies have been used to understand susceptibility and modifying factors in humans. Rat studies suggest that different types of altered pancreatic physiology occur depending on dose, they occur rapidly and that alcohol changes the immune response to recurrent pancreatic injury. Human studies suggest that PRSS1 and SPINK1 mutation increase the pancreas' susceptibility to alcohol-associated pancreatitis, and that tobacco smoking, and some factors, affect disease progression.

Abstract
Ursodeoxycholic acid (UDCA) and impaired gallbladder motility purportedly reduce biliary pain and acute cholecystitis in patients with gallstones. However, the effect of UDCA in this setting has not been studied prospectively. This issue is important, as in several countries (including the Netherlands) scheduling problems result in long waiting periods for elective cholecystectomy. We conducted a randomized, double-blind, placebo-controlled trial on effects of UDCA in 177 highly symptomatic patients with gallstones scheduled for cholecystectomy. Patients were stratified for colic number in the preceding year (<3: 32 patients; > or =3: 145 patients). Baseline postprandial gallbladder motility was measured by ultrasound in 126 consenting patients. Twenty-three patients (26%) receiving UDCA and 29 (33%) receiving placebo remained colic-free during the waiting period (89 +/- 4; median [range]: 75[4-365] days) before cholecystectomy (P = .3). Number of colics, non-severe biliary pain, and analgesics intake were comparable. A low number of prior colics was associated with a higher likelihood of remaining colic-free (59% vs. 23%, P < .001), without effects on the risk of complications. In patients evaluated for gallbladder motility, 57% were weak and 43% were strong contractors (minimal gallbladder volume > respectively < or = 6 mL). Likelihood to remain colic-free was comparable in strong and weak contractors (31% vs. 33%). In weak contractors, UDCA decreased likelihood to remain colic-free (21% vs. 47%, P = .02). In the placebo group, 3 preoperative and 2 post-cholecystectomy complications occurred. In contrast, all 4 complications in the UDCA group occurred after cholecystectomy. In conclusion, UDCA does not reduce biliary symptoms in highly symptomatic patients. Early cholecystectomy is warranted in patients with symptomatic gallstones.

Abstract
Gallstones are frequent in the Western world, with up to 10% of the general population affected. Gallstone prevalence is higher in the elderly and in women. Acute cholangitis and pancreatitis are the most serious complications of gallstones, with considerable morbidity and mortality. We discuss here clinical features, laboratory and radiological examinations, and treatment for gallstone cholangitis and pancreatitis. The diagnostic approach for acute 'idiopathic' pancreatitis is dealt with in some detail. Also, the role in pancreatitis of enteral nutrition, antibiotic prophylaxis, and the place of endoscopic retrograde cholangiography with papillotomy for biliary decompression is discussed in detail.

Abstract
Several risk factors for cholesterol gallstone formation in the general population have been identified. There is a strongly increased risk of gallstone disease during prolonged fasting, rapid weight loss, total parenteral nutrition, and somatostatin(-analogue) treatment. The annual risk of biliary colic and gallstone complications in asymptomatic gallstone carriers has been investigated sparsely. In asymptomatic and symptomatic gallstone carriers, treatment with the hydrophilic bile salt ursodeoxycholic acid (UDCA) has been claimed to reduce the risk of biliary colic and gallstone complications such as acute cholecystitis and acute pancreatitis. Also, prophylactic cholecystectomy could be beneficial in certain subgroups of asymptomatic gallstone carriers. However, randomized, double-blind, placebo-controlled trials are lacking. In this review, strategies for the prevention of gallstone formation in the general population and in high-risk conditions are dealt with. Also, strategies for the prevention of biliary colic and gallstone complications in asymptomatic and symptomatic gallstone carriers are discussed.

Abstract
OBJECTIVES Pancreatitis is a severe complication of gallstone disease with considerable mortality. Small gallstones may increase the risk of pancreatitis. Our aims were to evaluate potential association of small stones with pancreatitis and potential beneficial effects of prophylactic cholecystectomy. METHODS Stone characteristics were determined in patients with biliary pancreatitis (115), obstructive jaundice due to gallstones (103), acute cholecystitis (79), or uncomplicated gallstone disease (231). Sizes and numbers of gallbladder and bile duct stones were determined by ultrasonography and endoscopic retrograde cholangiopancreatography, respectively. Effects of prophylactic cholecystectomy were assessed by decision analyses with a Markov model and Monte Carlo simulations. RESULTS Patients with pancreatitis or obstructive jaundice had more and smaller gallbladder stones than those with acute cholecystitis or uncomplicated disease (diameters of smallest stones: 3 +/- 1, 4 +/- 1, 8 +/- 1, and 9 +/- 1 mm, respectively, p < 0.01). Bile duct stones were smaller in case of pancreatitis than in obstructive jaundice (diameters of smallest stones: 4 +/- 1 vs 8 +/- 1, p < 0.01). Multivariate analysis identified old age and small stones as independent risk factors for pancreatitis. Decision analysis in a representative group of patients with small (<or=5 mm) gallstones (5,000 patients, 67% females, 45 yr old, 10-yr follow-up) indicates that life-years may be gained or lost by cholecystectomy, depending on incidence and mortality of pancreatitis. CONCLUSIONS Small gallstones are associated with pancreatitis. Prophylactic cholecystectomy may lead to gain or loss of life-years in patients with small stones, depending on incidence and mortality of pancreatitis.
