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 ass
ociated with high mortality. Treatment is surgical resection of the in
volved segment. Several theories to explain the pathogenesis of jejuna
l diverticula may relate to manometric or histologic abnormalities of
the small bowel.
