Intussusception following jejunoileal bypass for morbid obesity: report of a case.

A man who had undergone jejunoileal bypass for morbid obesity had cramping abdominal pains for which no cause could be found, despite repeated clinical examinations and numerous investigations. Only during anesthesia could the large mass formed by the intussusception be palpated. Following reduction of the intussusception and refixing to the anterior abdominal wall, all symptoms abated.
