Paraduodenal hernia: An exceptional cause of acute bowel obstruction.

Internal hernias represent only 0.2%-0.9% of all causes of bowel obstruction. A 59-year-old patient presented urgently with small bowel obstruction. Laparotomy revealed a left paraduodenal hernia with most of the small bowel herniating through a space between the inferior mesenteric vein and duodenojejunal junction.
