Abstract
Acute diverticulitis of the right colon is a rare condition with a higher incidence in Oriental populations than in Occidental populations. A retrospective review was conducted between 1982 and 1993 on 22 surgically treated Chinese patients (14 men, 8 women; mean age 47 years) with documented right colon diverticulitis. Most patients presented with right lower quadrant pain and local peritoneal signs. Acute appendicitis was the preoperative diagnosis in 82% (18/22) of the patients. Only one diagnosis subsequently proved correct. The pathology was easily recognized in 4 patients during surgery, while examination of the resected specimen confirmed the intraoperative suspicion in 13 patients. The right colon was resected and an ileocolonic anastomosis performed in 21 patients; the remaining patient underwent diverticulectomy and drainage of a pericolic abscess. There was no postoperative mortality, and 4 patients developed wound infection. Our results showed that acute diverticulitis of the right colon was encountered once in 180 cases of acute appendicitis. Local resection or colectomy with primary anastomosis without bowel preparation is the procedure of choice.
