The use of manometry, i.e. the recording of pressures within hollow viscera, after being successfully applied to the study of esophageal and anorectal motor dysfunctions, has also been used to investigate physiological and pathological conditions of the small bowel. By means of this technique, it has been possible to understand better the normal motor functions of the small intestine, and their...

multiple esophageal diverticula is a rare entity that may be seen in the course of esophageal motor disorders. herein, i reported a 45 year-old man presented with intermittent chest pain and dysphagia since 20 years ago that exaggerated during the last six months. barium swallow and upper gi endoscopy revealed multiple diverticula along the esophagus and his esophageal manometry showed high amp...

Ambulatory pH-recording is one of the key diagnostic studies in gastroesophageal reflux disease. It is recommended that the pH-probe is inserted 5 cm above the proximal border of the lower esophageal sphincter (LES) and the latter should be determined optimally with manometry [1]. However, some studies have shown that the pH step-up especially done in the supine position could be almost as accu...

The anorectum plays an important role in regulation of defecation and in maintenance of continence [1]. The most widely used test for anorectal function is anorectal manometry. It measures pressures of the anal sphincter muscles, sensation in the rectum, and neural refl exes that are needed for normal bowel movements. This test is mainly used in evaluation of constipation, fecal incontinence, a...

Introduction: High resolution manometry is the current technology used to the study of esophageal motility and is replacing conventional manometry in important centers for esophageal motility with parameters used on esophageal motility, following the Chicago Classification. This classification unifies high resolution manometry interpretation and classifies esophageal disorders. Objective: Thi...

HYPOTHESIS Traditionally, patients with gastroesophageal reflux disease fall into 3 categories based on 24-hour pH testing and the clinical occurrence of their acid exposure. Patients with upright reflux are believed to do worse following surgery compared with supine or bipositional reflux patients. We assessed objective postoperative outcomes for patients with upright, supine, and bipositional...

BACKGROUND To compare the characteristics between 22-channel water-perfusion manometry (WPM) and solid-state manometry (SSM) with 36 sensors of the pressure measurements, as well as patients' discomfort indices in nose and pharynx, the preparation and operation time of the manometry. METHODS 12 volunteers were included in the study. Each of the volunteers underwent esophageal manometry by bot...

BACKGROUND/AIMS The pathophysiologic mechanism of rectal hyposensitivity (RH) is not well documented, and the significance of RH in biofeedback therapy (BFT) has not been evaluated. Thus, we aimed to assess the effect of BFT in constipated patients according to the presence of RH. METHODS Five hundred and ninety constipated patients (238 males and 352 females) underwent anorectal physiologic ...
