Combination of adult intussusception and intestinal malrotation: an unusual presentation.

Intussusception is familiar to pediatric surgeons but is rarely encountered by general surgeons. Adult intussusception is uncommon, accounting for less than 5% of intestinal obstructions, half of which are associated neoplasms. Intestinal malrotation is usually an incidental finding with unrelated disease on image studies, laparotomy or even autopsy. The major complications of intestinal malrotation are intestinal obstruction secondary to midgut volvulus, internal hernia, or adhesion band. The association of the two entities, which is named Waugh's syndrome in infants, has rarely been reported in the literature. The association in adults is even rarer. We report an adult case with an unusual combination of malrotation and intussusception at exploration.
