Revision laparoscopic gastric bypass: an effective approach following failure of primary bariatric procedures.

BACKGROUND

The laparoscopic approach plays an important role in the primary surgical management of morbid obesity. This study evaluated the potential role of the laparoscopic approach to revision Roux-en-Y gastric bypass (LRYGB) in the management of selected patients who fail to lose adequate weight or regain weight after primary bariatric surgery.

METHODS

Revision LRYGB was carried out to remedy early or delayed failure of primary bariatric procedures. Patients who underwent laparoscopic revision surgery to re-establish a functioning gastric band were not included in this report. The results are presented as mean (SD).

RESULTS

Between April 2002 and March 2009, 21 patients underwent 21 laparoscopic revision procedures. The initial bariatric operations were laparoscopic gastric band (n = 10), open vertical banded gastroplasty (n = 6), open Magenstrasse and Mill (n = 2), open gastric bypass with pouch dilatation (n = 2), and open gastric band (n = 1). All revision procedures were completed laparoscopically and included conversion to LRYGB (n = 19), and others (n = 2). The postoperative hospital stay was 2.0 (1.3) days. The anastomotic leak, morbidity, and mortality rates were 0%, 4.8%, and 0% respectively. At a follow-up of 12.9 (7.9) months, the prerevision body mass index has decreased significantly from 43.9 (7.4) to 32.7 (6.6) kg/m(2) (p < 0.001) with a percentage excess weight loss of 61.1 (21.2).

CONCLUSIONS

The laparoscopic approach to revision Roux-en-Y gastric bypass is safe and effective even in patients with previous open bariatric surgery and is associated with rapid recovery and short hospital stay.
