Abstract
Background and aim
For many years, esophageal manometry has been used for assessment of upper gastro-intestinal (GI) symptoms. Chicago classification is the key for diagnosis and managing motility disorders as it is considered as a standardized approach for categorization of esophageal abnormalities. The aim of this study is to analyze types of esophageal motility findings in Egyptian cases who were suffering from upper GI complaints. Methods: This descriptive study included 378 subjects who were suffering from upper GI complaints as dysphagia, vomiting, chest pain and regurgitation in the period between 10/2015–7/2020. Esophageal HRM study was performed for all patients (MMS Laborie device). The catheter was positioned and confirmed passing across the EGJ (esophago-gastric junction) using landmarks. Swallows and resting status were recorded. Anatomical landmarks were placed.
Results
Most of the patients were complaining of upper GI symptoms. Males were 49.2% of cases. Mean age was 41.3. Dysphagia was the prominent symptom while chest pain was the least symptom. Many manometry findings were observed including ineffective motility, achalasia, absent contractility, EGJ outflow obstruction, jackhammer esophagus and normal findings. Type II achalasia was the dominant type in achalasia patients while Type III was the least. LES was normotensive in most of the cases. Hiatus hernia (HH) was detected in 40.2% of the cases.
Conclusion
This is considered the first Egyptian descriptive study to determine the prevalence of esophageal motility abnormalities in Egyptian patients complaining of upper GI symptoms. HRM is very important for patients complaining of upper GI symptoms.

Abstract
The Chicago classification (CC) is most valued for its systematic approach to esophageal disorders and great impact in unifying practice for esophageal manometric studies. In view of the ever-growing wealth of knowledge and experience gained by the expanding use of high-resolution manometry (HRM) in various clinical scenarios, the CC is regularly updated. Its clinical impact and ability to predict clinical outcome, both in adults and pediatrics, will be further promoted by recognizing its current limitations, incorporating new metrics in its diagnostic algorithms and adjusting the HRM protocols based on the clinical question posed. Herein, we discuss the current limitations of the CC and highlight some areas of improvement for the future.

Abstract
BACKGROUND AND OBJECTIVES Many mathematical equations based on height have been developed to estimate the esophageal length (EL) in children. The aim of this study was to confirm whether the preexisting and most frequently used equation by Strobel et al is accurate in calculating the EL in our pediatric population. Our secondary goal was to evaluate whether a new formula could be developed using our nonsurgical and surgical populations' data for the correlation between patients' height and measured EL by esophageal manometry (EM). METHODS From 2000 to 2009, 116 children between the ages of 3 and 18 years without previous esophageal surgery underwent EM (n = 31) at the Montreal Children's Hospital. During the same period, 55 EMs were performed on 34 children with a previous history of esophageal surgery. For both groups, we collected the following data: height, EL calculated by the Strobel formula, and EL measured by EM. RESULTS The Strobel equation was inaccurate in predicting the EL. The calculated EL was 3.0 ± 0.32 cm longer than the EM measurements (P < 0.001). The height (H) of nonsurgical children was found to be highly predictive of the lower esophageal sphincter location (L), and the derived linear regression equation is L = 0.216 (H) + 7.13 [r² = 0.85]. CONCLUSIONS This study confirmed that the Strobel formula is not sufficiently accurate to predict EL in the pediatric population that is between 3 and 18 years old. A correlation exists between height and esophageal sphincter location position. If EM is unavailable, the use of a new mathematical equation like ours can be considered.

Abstract
Esophageal motor function is highly coordinated between central and enteric nervous systems and the esophageal musculature, which consists of proximal skeletal and distal smooth muscle in three functional regions, the upper and lower esophageal sphincters, and the esophageal body. While upper endoscopy is useful in evaluating for structural disorders of the esophagus, barium esophagography, radionuclide transit studies, and esophageal intraluminal impedance evaluate esophageal transit and partially assess motor function. However, esophageal manometry is the test of choice for the evaluation of esophageal motor function. In recent years, high-resolution manometry (HRM) has streamlined the process of acquisition and display of esophageal pressure data, while uncovering hitherto unrecognized esophageal physiologic mechanisms and pathophysiologic patterns. New algorithms have been devised for analysis and reporting of esophageal pressure topography from HRM. The clinical value of HRM extends to the pediatric population, and complements preoperative evaluation prior to foregut surgery. Provocative maneuvers during HRM may add to the assessment of esophageal motor function. The addition of impedance to HRM provides bolus transit data, but impact on clinical management remains unclear. Emerging techniques such as 3-D HRM and impedance planimetry show promise in the assessment of esophageal sphincter function and esophageal biomechanics.

World J Gastroenterol 2012; 18:5027-33. [PMID: 23049210 PMCID: PMC3460328 DOI: 10.3748/wjg.v18.i36.5027] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2012] [Revised: 05/18/2012] [Accepted: 05/26/2012] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate gastric motility using electrical bio-impedance (EBI) and gastric changes as a result of stress induced by psychological tests.
METHODS: A group of 57 healthy women, aged 40-60 years, was recruited, and a clinical history and physical examination were performed. The women were free from severe anxiety, chronic or acute stress, severe depression, mental diseases and conditions that affect gastric activity. The women were evaluated under fasting conditions, and using a four-electrode configuration, the gastric signals were obtained through a BIOPAC MP-150 system. The volunteers were evaluated using the following paradigm: basal state, recording during the Stroop Test, intermediate resting period, recording during the Raven Test, and a final resting period. We analyzed the relative areas of the frequency spectrum: A1 (1-2 cpm), A2 (2-4 cpm), A3 (4-8 cpm), and A4 (8-12 cpm), as well as the median of area A2 + A3. The data were analyzed by an autoregressive method using a Butterworth filter with MatLab and Origin. Analysis of variance (ANOVA) and Friedman ANOVA (for nonparametric variables) were performed; in addition, pairs of groups were compared using the T dependent and Wilcoxon T tests.
RESULTS: The results of the main values of area A2 were not significantly different comparing the five steps of the experimental paradigm. Nevertheless, there was a tendency of this A2 region to decrease during the stress tests, with recuperation at the final resting step. When an extended gastric region was considered (1-4 cpm), significant differences with the psychological stress tests were present (F = 3.85, P = 0.005). The A3 region also showed significant changes when the stress psychological tests were administered (F = 7.25, P < 0.001). These differences were influenced by the changes in the adjacent gastric region of A2. The parameter that we proposed in previous studies for the evaluation of gastric motility by electrical bio-impedance (EBI) was the median of the area under the region from 2 to 8 cpm (A2 + A3). The mean values of these frequencies (median of the A2 + A3 area) with the stress test showed significant changes (F = 5.5, P < 0.001). The results of the Wilcoxon T test for the A4 area parameter, which is influenced by the breathing response, changed significantly during the Raven stress test (P < 0.05).
CONCLUSION: We confirm that the gastric response to acute psychological stress can be evaluated by short-term EBI.

Abstract
The aim of this article is to identify non-invasive, inexpensive, highly sensitive and accurate techniques for evaluating and diagnosing gastric diseases. In the case of the stomach, there are highly sensitive and specific methods for assessing gastric motility and emptying (GME). However, these methods are invasive, expensive and/or not technically feasible for all clinicians and patients. We present a summary of the most relevant international information on non-invasive methods and techniques for clinically evaluating GME. We particularly emphasize the potential of gastric electrical bioimpedance (EBI). EBI was initially used mainly in gastric emptying studies and was essentially abandoned in favor of techniques such as electrogastrography and the gold standard, scintigraphy. The current research evaluating the utility of gastric EBI either combines this technique with other frequently used techniques or uses new methods for gastric EBI signal analysis. In this context, we discuss our results and those of other researchers who have worked with gastric EBI. In this review article, we present the following topics: (1) a description of the oldest methods and procedures for evaluating GME; (2) an explanation of the methods currently used to evaluate gastric activity; and (3) a perspective on the newest trends and techniques in clinical and research GME methods. We conclude that gastric EBI is a highly effective non-invasive, easy to use and inexpensive technique for assessing GME.

Evaluation and management of neonatal dysphagia: impact of pharyngoesophageal motility studies and multidisciplinary feeding strategy. J Pediatr Gastroenterol Nutr 2009; 48:186-92.

Abstract
BACKGROUND AND OBJECTIVES Abnormal swallowing (dysphagia) among neonates is commonly evaluated using the videofluoroscopic swallow study (VSS). Radiological findings considered high risk for administration of oral feeding include nasopharyngeal reflux, laryngeal penetration, aspiration, or pooling. Our aims were to determine pharyngoesophageal motility correlates in neonates with dysphagia and the impact of multidisciplinary feeding strategy. METHODS Twenty dysphagic neonates (mean gestation +/- standard deviation [SD] = 30.9 +/- 4.9 weeks; median 31.1 weeks; range = 23.7-38.6 weeks) with abnormal VSS results were evaluated at 49.9 +/- 16.5 weeks (median 41.36 weeks) postmenstrual age. The subjects underwent a swallow-integrated pharyngoesophageal motility assessment of basal and adaptive swallowing reflexes using a micromanometry catheter and pneumohydraulic water perfusion system. Based on observations during the motility study, multidisciplinary feeding strategies were applied and included postural adaptation, sensory modification, hunger manipulation, and operant conditioning methods. To discriminate pharyngoesophageal manometry correlates between oral feeders and tube feeders, data were stratified based on the primary feeding method at discharge, oral feeding versus tube feeding. RESULTS At discharge, 15 of 20 dysphagic neonates achieved oral feeding success, and the rest required chronic tube feeding. Pharyngoesophageal manometry correlates were significantly different (P < 0.05) between the primary oral feeders versus the chronic tube feeders for swallow frequency, swallow propagation, presence of adaptive peristaltic reflexes, oral feeding challenge test results, and upper esophageal sphincter tone. VSS results or disease characteristics had little effect on the feeding outcomes (P = NS). CONCLUSIONS Swallow-integrated esophageal motility studies permit prolonged evaluation of swallowing reflexes and responses to stimuli under controlled conditions at cribside. The dysfunctional neuromotor mechanisms may be responsible for neonatal dysphagia or its consequences. Manometry may be a better predictor than VSS in identifying patients who are likely to succeed in vigorous intervention programs.

Assessment of dysphagia in infants with facial malformations. Eur J Pediatr 2009; 168:187-93.

Abstract
In infants with facial malformation, dysphagia is frequent and can lead to respiratory and nutritional complications whatever the phenotype. The aim of our study was to assess the severity and mechanisms of dysphagia in infants with facial malformations in order to guide therapeutic management. Forty-two newborn infants with dysphagia and recognizable malformation patterns other than isolated Pierre Robin sequence had: (1) needle electromyography (EMG) of muscles of the face, tongue, and soft palate; (2) two-channel EMG during bottle feeding; and (3) esophageal manometry (EM). The results were compared by clinical dysphagia-grading groups and by age at cessation of enteral feeding. Although micrognathia (86%) and cleft or high-arched palate (76%) were common, the key clinical finding that correlated with the likelihood of respiratory complications was glossoptosis (p<0.01). EMG signs of denervation correlated with respiratory complications (p<0.05) and the duration of enteral feeding (p<0.01). EMG during bottle feeding showed disturbed motor organization at the pharyngeal level in 27 of 37 patients. The severity of pharyngeal incoordination correlated with the duration of enteral feeding (p<0.025). All 21 patients examined by EM had dysfunction at the esophageal level. Thus, in the assessment of upper digestive tract dysfunction, our clinical grading system, EMG, and EM yield convergent information that is relevant to the management of dysphagic infants with facial malformations. Much of the information is obtainable only from EMG.

Abstract
Most frequently, ten swallows of a 5-mL bolus of water are performed during oesophageal manometry. Our hypothesis is that five swallows may produce the same results. We studied the oesophageal contraction parameters of 40 volunteers, 75 patients with Chagas' disease and 14 patients with idiopathic achalasia. Motility was recorded at 5, 10 and 15 cm above the lower oesophageal sphincter. The subjects performed ten swallows of a 5-mL bolus of water alternated with ten dry swallows with an interval of at least 30 s. We measured the amplitude, duration, peristaltic velocity, number of failed and number of simultaneous contractions of the initial five and final five dry and wet swallows. The comparison of dry and wet swallows showed the differences already known. The comparison of the parameters of the initial five swallows with those of the final five swallows showed no differences. Thus, when the initial five or the final five swallows were considered, there was no change in the conclusions reached by the comparison of patients and volunteers and of dry and wet swallows. We conclude that five swallows may be sufficient for the manometric examination of oesophageal parameters in Chagas' disease and idiopathic achalasia.

Abstract
Motility disorders are common in children and may affect any area of the GI tract. The past decade has brought significant advances in the understanding of motility disorders in pediatrics. More sophisticated testing techniques have helped to differentiate normal from abnormal motility in children of different ages. Manometry now may be used to clarify the pathophysiologic defect underlying chest pain, dysphagia, rumination, gastroparesis, chronic intestinal pseudo-obstruction, and colonic neuromuscular disorders. Motility testing also may be used to identify the motor defect responsible for persistence of symptoms after surgery for GER or HD. New investigational techniques and prokinetic agents likely to be available in the future also were discussed.

Abstract
Children with gastrointestinal motility disorders present with diverse symptoms, and obtaining a detailed history is often impossible. As in adults, evaluation of a suspected motility disorder begins with exclusion of mechanical obstruction or primary inflammatory disorders. Subsequently, coordination of peristaltic function is evaluated in those segments of the gastrointestinal tract that are suspected to be abnormal based on the clinical history. Evaluation of gastrointestinal motility in children is particularly challenging because of frequent lack of patient cooperation and difficulties in adapting the equipment to patient size. This review discusses the indications and approach to the evaluation of motility of each region of the gastrointestinal tract in infants and children.
