Criteria for assessing esophageal motility in laparoscopic adjustable gastric band patients: The importance of the lower esophageal contractile segment

Abstract

Background: Esophageal function appears critical in laparoscopic adjustable gastric band (LAGB) patients; however, conventional motility assessments have not proven to be clinically useful. Recent combined video fluoroscopic and high-resolution manometric studies have identified important components of esophageal function in LAGB patients. Methods: Successful and symptomatic LAGB patients, with normal or mildly impaired esophageal peristalsis, underwent a standardized, water swallow, high-resolution manometry protocol designed specifically to assess the lower esophageal contractile segment (LECS), in combination with conventional measures of esophageal motility. Differences in response to ch..
