A loop of ileum containing oral contrast material is seen extending into an incisional ventral hernia. The bowel wall is mildly edematous with a narrow neck. Very little contrast passes distally.
Herniation through the anterior abdominal wall is frequently associated with prior surgery where the hernia occurs through the old incisional site as in this case. If the hernia cannot be reduced, it is called incarcerated and may result in bowel obstruction and possible strangulation or loss of blood supply to the herniated bowel. These latter finding require urgent surgical reduction to prevent morbidity and mortality.
