Aim The aim of this study was to evaluate and compare the functional results before and after laparoscopic Heller myotomy for Iranian patients with achalasia. Background Achalasia is a severe neuromuscular disorder of the esophagus, characterized by the loss of peristalsis and an inability of the lower esophageal sphincter (LES) to reach optimal relaxation. Methods In this cross sectional s...

First, they categorized 37 patients with hypotensive (weak) peristalsis with high integrated relaxation pressure (IRP) as having variant achalasia. However, in the recent Chicago Classification system, high IRP with some instances of intact or weak peristalsis such that the criteria of achalasia are not fulfiled are defined as esophagogastric junction (EGJ) outflow obstruction (2). Thus, in thi...

BACKGROUND/AIMS Most recent studies using high-resolution manometry were based on supine liquid swallows. This study was to evaluate the differences in esophageal motility for liquid and solid swallows in the upright and supine positions, and to determine the percentages of motility abnormalities in different states. METHODS Twenty-four asymptomatic volunteers and 26 patients with gastroesoph...
