Intersigmoid Hernia: A Case Report

Abstract

A 59-year-old female with a history of a hysterectomy presented with abdominal pain. An abdominal CT scan revealed a loop of small intestine with stenosis and a caliber change in the left lower abdomen. Adhesive bowel obstruction was diagnosed and a long tube was inserted, but the patient did not improve by eight days after admission. Laparoscopic exploration was performed. An intersigmoid hernia was found intraoperatively, with the small intestine incarcerated in the intersigmoid fossa. The small intestine was mobilized by incising the hernia ring. A partial resection of the small intestine was needed because of bowel strangulation with necrotic changes. We report herein on a patient with an intersigmoid hernia, with a review of previously reported cases in Japan.
