The authors report ten cases of small bowel diverticulosis revealed by a complication in four cases. Aetiologic, pathological, clinical and therapeutic characteristics of this rare disease are reviewed. Main complications are perforations, intestinal obstruction and hemorrhage. The treatment was the resection of the segment of small intestine involved by complicated diverticula. Resection was followed by anastomosis or temporary enterostomy if there was an acute peritonitis. Uncomplicated diverticulae must be respected and left in place.
