title: Right paraduodenal hernia.
abstract: Right paraduodenal hernias are uncommon. Approximately 50 cases have been reported and 2 more are reported in this paper. The diagnosis of internal hernia should be considered in all patients with abdominal cramps and intermittent small bowel obstruction. The most valuable investigation is roentgenography of the small intestine after barium ingestion; this usually shows a clumping of the intestine, as in a bag, with incomplete rotation of the cecum and ascending colon. Duodenal hernias should be  treated surgically even if they are asymptomatic, because they may cause potentially lethal complications such as obstruction. gangrene or bowel perforation.
