Abstract
We report a case of a 92-year-old woman with obturator hernia. She was admitted to our hospital due to anorexia that had persisted for a few days. On hospital day 3, her blood pressure suddenly decreased. Computed tomography showed intraperitoneal free air and incarceration of the small intestine into the left obturator foramen; thus, perforation peritonitis associated with left obturator hernia was diagnosed. The patient underwent emergency surgery. Operative findings showed perforation of the intestine secondary to the left obturator hernia and right obturator hernia. The manual pulling method was used for removal of the incarcerated small intestine in the obturator foramen, and partial resection of the small intestine was performed. Both obturator foramens were repaired using a simple nonabsorbable suture. The mortality of perforation peritonitis associated with obturator hernia is high, and early diagnosis using a pelvic CT scan is important to reduce mortality.
