Laparoscopic Roux-en-Y gastric bypass: 10-year follow-up.
BACKGROUND The short-term benefits of bariatric surgery are well documented ; however , few reports with data beyond 10 years exist . Those that have been published have described only open procedures . We present our 10-year follow-up results with  laparoscopic Roux-en-Y gastric bypass with h and -sewn gastrojejunal anastomosis in a group private practice . METHODS We performed an institutional review board-approved retrospective review of a prospect ively maintained data base , combined with office visits and telephone question naires , for patients who underwent laparoscopic Roux-en-Y gastric bypass between February 1998 and April 1999 . RESULTS A total of 242 patients underwent surgery from February 1998 to April 1999 . The office follow-up rate was 33 % at 2 years and 7 % at 10 years . An additional 19 % had telephone follow-up at 10 years . The mean excess weight loss was 57 % at 10 years . Of the 242 patients , 65 ( 33.2 % ) failed to achieve an excess weight loss of > 50 % ; 86 ( 35 % ) had ≥1 complication during follow-up . However , 83 % , 87 % , 67 % , and 76 % of patients with diabetes , hypertension , dyslipidemia , and obstructive sleep apnea , respectively , experienced improvement or resolution . The internal hernia rate was 16 % , and the gastrojejunal stenosis rate was 4.9 % . No surgery-related deaths occurred . Of the 242 patients , 136 ( 51 % ) had nutritional testing at least once after postoperative year 1 . Of these 136 patients , only 24 ( 18 % ) had remained nutritionally intact during follow-up . CONCLUSION The obstacles to follow-up have continued to impede the collection of accurate long-term data . Of the 26 % of patients with data , laparoscopic Roux-en-Y gastric bypass provided sustainable weight loss and resolution of co-morbidities . However , nutritional deficiencies presented sporadically over time and underscore the importance of routine testing
