Small-bowel diverticulosis.

Diffuse jejunoileal diverticulosis with pneumoperitoneum but without peritonitis is an uncommon but well-documented entity. Cases of jejunoileal diverticular perforation in which the perforation is evident are managed with resection of the diseased bowel and primary anastomosis. In the absence of an intraoperative finding of a perforation or an area of discrete inflammation, copious irrigation and closure of the abdomen is appropriate in cases of diffuse small-bowel diverticulosis.
