Gastric remnant perforation due to trocar site herniation after laparoscopic Roux-en-Y gastric bypass

A 39-year-old woman was admitted with colicky left upper-quadrant pain, dyspnoea, low-grade fever, tachycardia and a subtle left upper-quadrant tenderness without leucocytosis. Computed tomography revealed a distended gastric remnant due to small-bowel loop herniation at the trocar site. The patient underwent a diagnostic laparoscopy as her general condition worsened. Perforation across the staple line was seen and repaired. The postoperative period was uneventful. As a rare complication of laparoscopic Roux-en-Y gastric bypass, small-bowel obstruction is of great importance because it can lead to gastric remnant perforation if not managed correctly. There have been rare reports of trocar site herniation as a cause of small-bowel obstruction following laparoscopic Roux-en-Y gastric bypass. Prompt diagnostic laparoscopy should be considered. This is the first case reported in which the excluded stomach was perforated due to trocar site herniation of the small-bowel loop. It should be noted that the tissue around the perforation is fragile and proper tension should be employed when it is repaired. Generally, an omental patch is not encouraged.
