We present a video of an interesting case of acute small bowel obstruction from internal herniation at the Petersen's defect after a previous gastric bypass. The obstruction was unusual and interesting because there was marked lymphatic and venous congestion with chylous ascites.

The video demonstrates a systematic approach for the reduction and repair of internal hernias after gastric bypass. We believe the video will be of interest to bariatric surgeons and emergency general surgeons and will encourage them to tackle these cases laparoscopically.
