Abstract
We experienced three rare cases of intersigmoid hernia. Case 1, a 34-year-old woman presented with left lower abdominal pain and vomiting with no history of abdominal surgery. On the third hospital day, abdominal pain became worse and an emergency operation was performed under a diagnosis of strangulated ileus. Case 2, a 36-year-old man presented with left lower abdominal pain. He had a past history of laparoscopic surgery 20 years earlier for duodenal perforation. Strangulated ileus was suspected on abdominal computed tomography, and an emergency operation was performed. Case 3, an 81-year-old woman presented with left lower abdominal pain and vomiting with no history of abdominal surgery. Conservative therapy was started but was unsuccessful, and an emergency operation was performed on the third hospital day. All cases were diagnosed as strangulated ileus preoperatively, and intersigmoid hernias were disclosed at laparotomy. We did not perform any resections of the small intestine.
Intersigmoid hernia is a very rare entity. We report here three cases together with a review of the literature.
