Laparoscopic Roux-en-Y gastric bypass in patients with congenital malrotation.
Bariatric surgery is the only solution for morbidly obese individuals who desire to lose weight and maintain it and have failed to do so by non-surgical means. As the incidence of morbid obesity rises, laparoscopic Roux-en-Y gastric bypass (LRYGBP) is increasingly performed. With the increase in bariatrics, the chances of discovering aberrant anatomy at the operating-table also increase. We present two cases of LRYGBP in patients with intestinal malrotation, which is a congenital anomaly caused by failure of the intestines to rotate and fixate at 270 degrees during embryonic development. It occurs in one out of every 500 births in the United States, accounting for 5% of all intestinal obstructions. To this date, only three reports have been published describing the incidental finding of congenital malrotation during the initial laparoscopic exploration for gastric bypass. We found that the operation can still be performed laparoscopically in such patients, with some modifications to the standard technique.
