Abstract

Background: Pouch enlargement and band slippage are the most common late complications of laparoscopic adjustable gastric banding (LAGB). Often, confusion exists among surgeons regarding the denomination or even the treatment of these two different entities. This study aimed to establish the differences in clinical presentation, radiologic features, and management between pouch enlargement and band slippage. The authors hypothesized that pouch enlargement can be managed nonoperatively (via band deflation), that band slippage is an acute complication requiring surgical treatment, and that tailored adjustment allows earlier diagnosis of pouch enlargement in asymptomatic patients. Methods: From March 2001 to December 2004, 516 patients underwent LAGB placement. Barium swallow was performed preoperatively, postoperatively, and during band adjustments ("tailored adjustment"). Pouch enlargement was defined as dilation of the pouch, and band slippage was considered when band and stomach were prolapsed. Four radiologic types of pouch enlargement were considered: band 45°, band 45° with covering of the band, band 0°, and band smaller than 0°. Results: A total of 1,600 barium swallows were performed with 516 patients. As a result, pouch enlargement was diagnosed for 61 patients (12%) and band slippage for 12 patients (2%). Conclusion: In this study, pouch enlargement was found to be a chronic complication that can be managed conservatively with a 77% success rate. Tailored adjustment allows early diagnosis of pouch enlargement, thus preventing adjustments in patients with undiagnosed pouch enlargement. Surgical treatment should be considered when medical treatment fails. By comparison, band slippage is an acute complication that requires surgical treatment in every case (100%).
