Jejunal diverticulitis.

A case of perforated jejunal diverticulitis in a 44-yr-old man is described and the literature is reviewed. Jejunal diverticulosis occurs in 0.07% to 2% of the population. Enteroclysis is the best diagnostic test. Diverticulitis with perforation is rare and is associated with high mortality. Treatment is surgical resection of the involved segment. Other complications are bacterial overgrowth, obstruction, and acute hemorrhage. Several theories to explain the physiopathogenesis of the diverticula formation may relate to manometric or histological abnormalities of the small bowel.
