Radiological features of complications of laparoscopic adjustable gastric banding.

ABSTRACT

PURPOSE: Laparoscopic adjustable gastric banding (LAGB) is used to treat morbid obesity. We reviewed the associated complications with emphasis on radiological features and the role of radiology in suspected complications. MATERIALS AND METHODS: Between 30 January 2001 and 3 October 2006, 313 consecutive LAGB patients' data was entered into a prospective database. A contrast swallow was routinely performed on the first postoperative day, and port adjustments were done at variable intervals. Additional radiological studies were performed in patients with suspected complications. RESULTS: Of 313 patients who underwent LAGB, 46 had 51 complications (16.3%). The commonest complications were LAGB system leakage (5.1%), anterior band slippage (3.5%) and infected port (1.6%). Two mortalities (0.6%), one early and one late, occurred. CONCLUSIONS: LAGB is a relatively low-risk procedure widely performed for treating morbid obesity. Imaging plays a pivotal role in the early evaluation and detection of LAGB complications.
