Effects of gastric band adjustments on intraluminal pressure

Abstract

Background: Understanding of the effects of adjustments to laparoscopic adjustable gastric band (LAGB) volume is limited. Changes in intraluminal pressure may be important and explain patients reporting a tighter LAGB after saline is removed and an identical volume replaced. Methods: Using high-resolution manometry, changes in the basal intraluminal pressure at the level of the LAGB in response to sequential, small alterations in LAGB volume were recorded. All fluid was removed from the LAGB and replaced, pressures and motility were reassessed. Results: Sixteen patients (four males, age 45.4±13.2 years) participated. A linear increase (r 2=0. 87±0.12) in intraluminal pressure was observed af..
