    Abstract:
    INTRODUCTION: Left-sided diverticulitis is a common disease in Western countries, whereas right-sided diverticultitis is rare and symptoms are often similar to the clinical signs of an acute appendicitis. It was the aim of this study to analyse surgical experience in right-sided diverticulitis. METHODS: All patients who underwent resectional surgery for both right-sided and sigmoid diverticular disease were entered prospectively in a registry database (8-year observation period, 1996-2003). For the current study, a retrospective analysis of all patients who underwent ileocolic resection or right colectomy for right-sided colonic diverticulitis was performed, specifically focussing on incidence, clinical symptoms, indication for surgery, type of procedure, and histopathological parameters including immunohistochemistry, and outcome in right-sided diverticulitis. RESULTS: Within eight years, 481 patients were treated surgically for chronically recurrent or acute complicated diverticular disease: 468 patients with sigmoid diverticulitis, 12 patients with right-sided diverticulitis, and 1 patient with combined right-sided and sigmoid diverticular disease. This corresponds to an incidence of right-sided diverticulitis of 2.5 % related to the total number of resections for diverticulitis, and an incidence of 1.3 % in relation to the appendectomies in our patients. In 4 patients, acute appendicitis was presumed preoperatively. Most common diagnostic tool was ultrasonography. Right colectomy was performed in 9 patients with complicated cecal diverticulitis, whereas ileocolic resection was performed in 2 patients and simultaneous ileocolic and sigmoid resection was carried out in one patient. Postoperatively, no morbidity occurred. Histopathological assessment showed local perforation in 75 % (9/12). Hypoganglionosis or aganglionosis was detected in 5 of 12 resected specimen. DISCUSSION: As right-sided diverticulitis is a rare colonic disease in Western countries, the differentiation from acute appendicitis can be difficult. In general, there is no difference in the treatment of right-sided diverticulitis compared to left-sided diverticulitis, and surgery is only indicated in complicated right-sided diverticulitis. Resection of the inflamed colon with primary anastomosis is safe and can be performed by laparoscopy in experienced centers. At present, it can only be speculated whether hypoganglionosis or aganglionosis are causative factors in the etiology of right-sided diverticulitis.
