Purpose
While the incidence of right colonic diverticulitis (RCD) is rare in Western countries, the right colon is the most common site of diverticulitis in Asian countries. However, its recurrent pattern and management were rarely studied. This study was designed to elucidate the pattern of recurrence in RCD.
Methods
Of the 154 patients admitted as right colonic diverticulitis between February 2004 and March 2012, 104 patients were enrolled, prospectively. The recurrence rate, size, multiplicity, location, diagnostic criteria score, and predisposing factors were evaluated based on Hinchey’s classification of diverticulitis.
Results
There were 104 patients with right colonic diverticulitis in this study, and 20 patients (19.2 %) recurred after medical treatment. When the diverticula were not located in the right colon, the recurrence rate was significantly higher than the diverticula located only in the right colon (p = 0.004). The recurrence rate of diverticulitis for a single diverticulum was significantly lower than that for multiple diverticula (p = 0.02). Of the 20 patients with recurrence, 1 (5 %) patient underwent laparoscopic diverticulectomy due to a misdiagnosis of diverticulitis as appendicitis. The remaining 19 patients (95 %) received nonoperative management and recovered without any sequelae.
Conclusions
The recurrence rate was 19.2 %, and the predisposing factors were the location of diverticula and the multiplicity of primary diverticula. The re-recurrence rate of recurred patients was 26.3 %. The recurred lesions were controlled simply by nonoperative management. Elective surgery was also a treatment option.
