Diverticulosis of the jejunum, generally considered to be an asymptomatic condition, may produce a variety of interesting clinical and pathophysiologic syndromes which are correctable by surgical intervention. In a group of 62 patients with jejunal diverticulosis seen at the Cincinnati General Hospital and associated hospitals of the University of Cincinnati, the natural history and complications of this poorly understood condition have been delineated. In this series significant symptomatic complications have occurred in 16 patients, and these form the basis of this report.
As seen at operation or the autopsy table, acquired jejunal diverticula appear as thinwalled, round, elliptical or multilobulated sacs continuous with the wall of the intestine and extending between the leaves of the mesentery, in contrast to the congenital Meckelian diverticulum which arises from the antimesenteric border of the intestine. A branch of the mesenteric vessel can often be seen coursing across the fundus of a sac. When
