Laparoscopic gastric bypass, Roux en-Y: Experience of 27 cases, with 3-18 months follow-up

Gastric Bypass, Roux en-Y, has been performed laparoscopically in 27 patients from October 1993 to June 1995. Weight loss ranged from a mean of 46% of excess body weight at 3 months (n = 27) to 101% at 18 months (n = 5). pre-operative co-morbidities were relieved or improved in nearly all instances: Gastroesophageal reflux was completely relieved in 21 of 22 patients. Diabetes mellitus was normalized in 13 of 13 patients. Morbidity is comparable to the open operation, while length of stay and disability are less. Cosmetic results are excellent. Laparoscopic Gastric Bypass, Roux en-Y is a feasible and valuable procedure.
