Abstract

A 39-year-old man complaining of epigastric pain was admitted to our hospital and diagnosed by abdominal X-rays as having intestinal obstruction. He had no past history of abdominal surgery. Because abdominal computed tomography showed dilatation of the small intestine, the patient underwent conservative therapy using a long tube. Although symptomatic remission could be achieved with depression of the intestine, intestinal contrast study through the long tube still showed obstruction of the small intestine. Internal hernia was strongly suspected and so laparoscopic surgery was performed. Laparoscopic observation revealed that the expanded ileum went around the back of the sigmoid colon and incarcerated into a mesenteric defect on the left side of the sigmoid colon in a Richter-type manner. A diagnosis of intramesosigmoid hernia was made, and incarceration was easily reduced by dissection of the right side of the mesocolon forming the hernia sac without intestinal resection. The postoperative course was uneventful and the patient was discharged on the 7th postoperative day. Internal hernia by sigmoid mesocolon is a rare disease, occurring in less than 5% of all internal hernias. We report a rare case of intramesosigmoid hernia, the incarceration of which was reduced by laparoscopic surgery.
