Prediction and management of recurrent right colon diverticulitis
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 design ed to eluci date 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 , prospect ively . 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
