Laparoscopic Roux-en-Y gastric bypass in intestinal non-rotation.

There are some incidental findings during bariatric surgery. Some of these findings may make the operation more challenging than routine surgery. Intestinal malrotation/non-rotation are rare congenital anomalies that may remain asymptomatic until bariatric surgery. Here we report a 30-year-old female patient with unknown intestinal congenital anomaly which was diagnosed during surgery and she underwent Roux-en-Y gastric bypass, which can be a challenging procedure in intestinal malrotation/non-rotation and conversion may be needed.
