Among internal hernias, those through the foramen of Winslow are most commonly observed. The least frequently occurring is that through the broad ligament of the uterus. The present case presented with bowel strangulating obstruction due to a defect of the left broad ligament which could be diagnosed prior to laparotomy. The patient had no significant past history, and had symptoms of colicky pain, nausea, and vomiting. Emergency laparotomy was performed. Gangrenous ileum was resected, and a defect of the broad ligament was observed bilaterally. Past history in this case supported congenital defect of the broad ligament.
