OBJECTIVES: 1. To evaluate the role of anorectal manometry in recognizing patients with histological abnormalities of the myenteric plexus as the cause of chronic constipation. 2. To correlate clinical features with the etiology of the constipation.METHODS: The etiology of the constipation was identified retrospectively from the medical records of 57 patients submitted to anorectal manometry. T...

OBJECTIVES The aim of this study was to assess the clinical utility of esophageal manometry among Sudanese patients presenting to the National Centre for Gastrointestinal and Liver Diseases, Ibn Sina Hospital, Khartoum, Sudan. METHODOLOGY Consecutive patients referred for esophageal manometry at the aforementioned center from July 2008 through January 2011 were included in the study. Manometr...

Anorectal manometry provides an objective assessment of anal sphincter pressure and rectal sensitivity and anorectal reflexes in response to distension. However, its clinical utility is hampered by a lack of standardized protocols and normative data from healthy subjects. Previous studies have used water-perfused systems in normal subjects, but some adopted a rapid pull-through technique; other...

AIMS To test the usefulness of upper gastrointestinal investigations and quality of life assessment in Chinese patients with non-cardiac chest pain. METHODS Seventy-eight consecutive patients with non-cardiac chest pain underwent upper endoscopy. Eight patients had upper gastrointestinal pathology (10%). The remaining 70 patients received acid perfusion test, oesophageal manometry and 24-h am...

Assessment of patterns of flow in the small bowel is difficult. Multiple intraluminal impedance has been recently used for study of flow dynamics in the esophagus. Our aims were 1) to validate multiple intraluminal impedance by correlating impedance events with intestinal flow as detected by fluoroscopy and 2) to determine intestinal flow patterns in the fasting and postprandial period and thei...

Achalasia is a primary neurodegenerative disorder of the esophagus characterized by loss of function of the lower esophageal sphincter (LES) and of esophageal peristalsis, which causes symptoms such as dysphagia, regurgitation, weight loss, and chest pain. Esophageal manometry is the gold standard for the diagnosis of achalasia. The typical manometric features are incomplete relaxation of a fre...

BACKGROUND & AIMS High-resolution manometry with spatiotemporal representation of pressure data is a technique that has developed during the past 10-15 years. We compared spatiotemporal and traditional line plot representation of manometry data in a group of medical students in terms of the ability of the user to come to a rapid and accurate diagnosis and evaluated user preferences for the 2 fo...
