Petersen's hernia refers to an internal herniation of small bowel through the potential space between the transverse mesocolon and the Roux limb of gastrojejunal anastomosis. The incidence of this is increasing with the widespread practice of bariatric surgery in the last decade. In this report, we present the case of a 44-year-old male who had undergone a laparoscopic Roux-en-Y gastric bypass for morbid obesity and presented after 14 months with a history of nonspecific abdominal pain. The examination of his abdomen was unremarkable. The computed tomography scan revealed the suspicious features of internal herniation of the small bowel and a twist in the mesentery. On diagnostic laparoscopy, he was found to have Petersen's space hernia. His clinical presentation, investigations, and treatment have been highlighted in this case report with a review of the literature. Although rare, Petersen's hernia could lead to a disastrous complication of small bowel strangulation if not intervened early. Hence, if suspected, the threshold to perform a diagnostic laparoscopy should be low.
