Popis: The effect of the laparoscopic adjustable gastric band (LAGB) on esophageal acid exposure and reflux is poorly understood. Optimal technique and normative values for acid exposure have not been established in this group. High-resolution manometry (HRM) and 24-h ambulatory esophageal pH monitoring were performed in three groups: asymptomatic LAGB, symptomatic LAGB, and pre-operative reflux patients. This technique utilized intraluminal pressure signatures during HRM to guide accurate pH sensor placement. The LAGB groups were well matched: age 48 vs 51 years (p = 0.249), weight loss 27.3 vs 26.7 kg (p = 0.911). The symptomatic group had a larger gastric pouch (5.2 vs 3.3 cm, p = 0.012), with higher esophageal acid exposure (10.8 vs 0.9%, p
