Laparoscopic reduction of an ileoileal anastomosis foramen of Winslow internal hernia.

Internal hernias are particularly difficult to diagnosis and should be considered in patients presenting with sudden, severe abdominal pain and symptoms of intestinal obstruction. Internal hernias carry a high risk of morbidity and mortality. Here, we present an unusual case of internal hernia through the foramen of Winslow of an ileoileal anastomosis created 25 years prior that was successfully diagnosed and operatively reduced via single-port laparoscopy with an optimal clinical outcome. Uniquely, the defect was closed using a ligamentum teres buttress to avoid undue tension at the foramen.
