Surgical revision after failure of laparoscopic adjustable gastric banding

This paper reports the outcome of surgical revision for complications following laparoscopic placement of an adjustable silicone gastric band (AGB) to treat morbid obesity.

Seventy-three (19.1 per cent) of 382 patients who underwent laparoscopic AGB placement between January 1996 and March 2001 presented with complications within 6 years after operation. Revision was carried out with the intention of reinstating the functional device in all patients.

Successful surgical revision or gradual balloon deflation was performed in 53 patients (29 port-related complications, 14 pouch dilatations, 12 band leakages, three oesophageal dilatations, two symptomatic hernias, one late migration, one intracerebral bleed). Of these patients, 51 (96.2 per cent) had a successful outcome according to the Bariatric Analysis and Reporting Outcome System following significant additional postinterventional weight loss. AGB removal was carried out in 20 patients (13 early or late migrations, five pouch dilatations, three port-related complications, two psychiatric disorders, one band leakage). The final failure rate for complicated AGB procedures was 30.1 per cent.

AGB placement is associated with a variety of complications. In most cases surgical complications can be treated with minimally invasive surgery, which should allow further weight loss and improvement of quality of life during long-term follow-up. Alternative bariatric procedures should be reserved for patients with poor outcome after surgical revision of the AGB.
