To investigate the clinical characteristics of colonic diverticulosis and the surgical method and curative effect of laparoscope in colonic diverticulosis.

From June 2013 to July 2018, thirty-two cases of colonic diverticulosis diagnosed in Guangzhou Huadu District People’s Hospital were retrospectively analyzed. There were eleven males and twenty-one females. Diverticles occurred in rectum in four cases, sigmoid colon in two cases, left colon in six cases and ileocecal in twenty cases. The operation was terminated in two cases because the family refused to undergo intestinal resection. Thirty cases underwent intestinal resection, including sigmoidectomy in two cases, rectal resection in four cases, right hemicolectomy in eleven cases, partial resection of descending colon in five cases, ileocecal resection plus jejunocolic anastomosis in eight cases, of which seven cases underwent temporary descending colon fistula and were admitted half a year later. Laparoscopic exploration and conversion to laparotomy were performed in fourteen cases, laparoscopic surgery was performed in sixteen cases.

The symptoms were relieved after anti-infection treatment in two cases, after 1 month of follow-up, colonoscopy was not positive, and diverticulitis had not recurred so far. Thirty cases gained satisfactory postoperative recovery results, no symptoms such as diarrhea and feces were found during follow-up. There was no significant difference in the incidence of complications between ileocecal resection and right hemicolectomy (50.0% vs36.4%, χ2=1.584, P=0.812). The recovery of gastrointestinal function in laparoscopic surgery group was faster than that in open surgery group (t=8.062, P<0.01), and the hospitalization time was shorter (t=8.607, P<0.01).

Partial intestinal resection in the first stage is safe and effective after diagnosis of colonic diverticulum. Laparoscopic partial intestinal resection has more advantages than traditional surgery.
