Two patients with strangulated intestinal obstruction due to internal hernia associated with trauma admitted to the Third Surgical Service at St. Luke's Hospital aroused our interest in this condition, especially since the first of these patients is our father. Intestinal obstruction caused by internal hernia is relatively uncommon, the incidence ranging from less than 0.01% to 5% of all cases of acute intestinal obstruction in various series.
