Revisional bariatric surgery after failed laparoscopic adjustable gastric banding - a single-center, long-term retrospective study.

Abstract

IntroductionLaparoscopic adjustable gastric banding (LAGB) used to be one of the most popular bariatric procedures.AimTo present our institution’s experience with LAGB, its complications, causes of failure and revisional bariatric procedures, in a long-term follow-up.Material and methodsRecords of patients who underwent pars flaccida LAGB from 2003 to 2006 were gathered. We selected data on patients with a history of additional bariatric procedures. Their initial demographic data, body mass index and causes of revision were gathered. We analyzed length of stay and early perioperative complications.Results60% of patients (n = 57) who underwent LAGB in our institution between 2003 and 2006 had their band removed (out of 107, 11% lost to follow-up). Median time to revisional surgery was 50 months. The main reasons for removal were: weight regain (n = 23; 40%), band slippage (n = 14; 25%), and pouch dilatation (n = 9; 16%). Thirty (53%) patients required additional bariatric surgery, 10 (33%) of which were simultaneous with band removal. The most popular procedures were: laparoscopic Roux-en-Y gastric bypass (LRYGB) (n = 15; 50%), open gastric bypass (n = 8; 27%), and laparoscopic sleeve gastrectomy (LSG) – (n = 3; 10%). Mean length of stay (LOS) was 5.4 ±2.0. One (3%) perioperative complication was reported.ConclusionsThe results show that LAGB is not an effective bariatric procedure in long-term follow-up due to the high rate of complications causing band removal and the high rate of obesity recurrence. Revisional bariatric surgery after failed LAGB may be performed in a one-stage approach with band removal.
