ABSTRACT
Primitive internal hernias are a rare cause of intestinal obstruction. They are often paraduodenal even transmesocolic, but only rarely transomental. We present a rare case of an internal abdominal hernia in a young man. The small bowel was strangulated by an intra mesenteric appendicitis. This hernia was revealed by abdominal pain, nausea and vomiting. Plain X-ray of the abdomen showed dilated jejunal and ileal loops with multiple air-fluid levels. The diagnosis of appendicitis was suggested by ultrasound but the internal hernia was found only upon surgical exploration. An appendicectomy and adhesiolysis were performed. The patient recovered fully after 3 days, and had an uneventful postoperative course. The authors discuss the possible cause of this rare intestinal obstruction.
