Abstract
A 74-year-old female visited the emergency outpatient department because of repeated vomiting after undergoing an extended hysterectomy for pre-existing endometrial cancer. Slight tenderness was observed in the right hypogastrium, and an X-ray examination of the abdomen revealed localized mild intestinal dilation. She was diagnosed as having a strangulated ileus on the basis of the abdominal CT findings, and emergency surgery was performed. The small intestine formed dilated loops because of a cord-like structure, which ran along the right external iliac artery. This structure was confirmed to be the right external iliac vein. We were able to reposition the incarcerated and dilated bowel manually. We think that an internal hernia was caused by straying of the small intestine into the gap present between the external iliac vein and external iliac artery, and this resulted in the strangulated ileus formation.
