    BackgroundRoux-en-Y gastric bypass (RYGB) is considered the "gold standard" revision procedure. The purpose of this study was to compare the surgical outcome of primary laparoscopic RYGB (pLRYGB) to revisional open or laparoscopic Roux-en-Y gastric bypass surgery (rRYGB).MethodsA retrospective analysis of all patients who underwent pLRYGB or rRYGB from January 2003 to December 2009 has been performed. Demographics, indications for revision, and complications have been reviewed. The rRYGB and pLRYGB patients have been compared.ResultsSeventy-two patients underwent rRYGB, and 652 patients underwent pLRYGB. Mean follow-up was 35 and 45 months, respectively. Fifty-six rRYGB procedures were performed laparoscopically. The primary operations had consisted of laparoscopic gastric banding (n = 28), laparoscopic vertical banded gastroplasty (n = 19), laparoscopic sleeve gastrectomy (n = 6), laparoscopic RYGB (n = 3), and biliopancreatic diversion with duodenal switch (n = 16). Indications included weight regain (n = 29), malabsorption (n = 16), gastrogastric fistula (n = 5), band-associated problems (n = 3), and refractory stomal ulceration (n = 1). There was no significant difference in early or late postoperative complications when comparing rRYGB to pLRYGBP patients (11.1% vs. 5.52%, P = 0.069 and 19.4% vs. 24.2%, P = 0.465 respectively). Five rRYGB patients (7.04%) required reintervention (3 internal hernias, 1 ventral hernia, 1 laparoscopic exploration) compared with 101 pLRYGB patients (15.71%; P = 0.051). None of the patients died. Mean hospital stay was not significantly longer in the rRYGB group (5.38 vs. 4.95 days, P = 0.058).ConclusionsIn our series, hospital stay, morbidity, and mortality of rRYGB were not significantly higher compared with pLRYGB. Furthermore, we believe that this type of revisional bariatric surgery should be performed in high-volume bariatric centers.
