Strangulated herniation of bowel occuring through a defect of the broad ligament is extremely rare. A recent episode of such a herniation of small bowel through the left mesosalpynx is presented. A review of literature reveals 61 cases previously reported. A classification with 4 types of defects is described. Without antecedent of uterine surgery, delivery trauma and congenital abnormalities are considered to be causes of these defects although real mechanism is unknow. Preoperative CT scan is helpful in suggesting the diagnosis:pelvic loop dilatation, uterine latereral deviation. Surgical management includes reperitonealization of the defect and inspection of the controlateral broad ligament.
