Perforated solitary jejunal diverticulum.

We report a case of perforated solitary jejunal diverticulum in an 80-year-old woman. Jejunal diverticulosis occurs in 0.07% to 2.0% of the population. Jejunal diverticulitis with perforation is rare and is associated with high mortality. Treatment is surgical resection of the involved segment. Several theories to explain the pathogenesis of jejunal diverticula may relate to manometric or histologic abnormalities of the small bowel.
