Three-year experience of pouch dilatation and slippage management after laparoscopic adjustable gastric banding.

Purpose: Pouch dilatation and band slippage are the most common long-term complications after laparoscopic adjustable gastric banding (LAGB). The aim of the study is to present our experience of diagnosis and management of these complications.

Materials And Methods: The pars flaccida technique with anterior fixation of the fundus was routinely used. All band adjustments were performed under fluoroscopy. We analyzed the incidence, clinico-radiologic features, management, and revisional surgeries for treatment of these complications. We further presented the outcome of gastric plication techniques as a measure for prevention of these complications.

Results: From March 2009 to March 2012, we performed LAGB on 126 morbidly obese patients. Among them, 14 patients (11.1%) were diagnosed as having these complications. Four patients (3.2%) had concentric pouch dilatations, which were corrected by band adjustment. Ten (7.9%) had eccentric pouch with band slippage. Among the ten patients, there were three cases of posterior slippage, which were corrected by reoperation, and seven cases of eccentric pouch dilatation with anterior slippage. Three were early anterior slippage, which was managed conservatively. Two were acute anterior slippage, one of whom underwent a revision. There were two cases of chronic anterior slippage, one of whom underwent a revision. The 27 patients who underwent gastric plication did not present with eccentric pouch with band slippage during the follow-up period.

Conclusion: The incidence of pouch dilatation with/without band slippage was 11.1%. Management should be individualized according to clinico-radiologic patterns. Gastric plication below the band might prevent these complications.
