[Complicated colonic diverticulosis. Results of surgical treatment between 1981 and 1998 in 370 patients]. / Les diverticuloses coliques compliquées. Résultats du traitement chirurgical entre 1981 et 1998 chez 370 patients.

AIM OF THE STUDY: The aim of this retrospective study was to analyze case reports of all the patients with complicated diverticular disease of the colon admitted in the same surgical center during an 18-year period and to report the postoperative results in patients operated on in emergency and in patients operated on electively. PATIENTS AND METHOD: From 1981 to 1998, 501 patients were admitted for complicated diverticular disease. There were 233 men and 268 women. Mean age was 66 years (range: 27-96). One hundred and thirty-one patients were only treated medically and 370 patients were operated on, either as an emergency (n = 211) or electively (n = 159). The complicated diverticular disease was located on the left colon in 362 cases and in the right colon in 8 cases. RESULTS: In the emergency group, 103 patients were operated on for pelvic (n = 24) and generalized purulent (n = 67) or stercoral (n = 12) peritonitis, mainly with Hartmann procedure (n = 80) with 14 postoperative deaths; 67 were operated on for pericolic abscess with 6 deaths, 19 for colonic obstruction with two deaths and 22 for profuse hemorrhage with 4 deaths. The overall postoperative mortality rate was 12.3%, and morbidity rate 38.7%. Intestinal continuity was restored in 74% and eventrations were present in 10%. In the elective group, there were two postoperative deaths in patients with a colic fistula (n = 30), no mortality and a 10.8% morbidity rate in the other patients (n = 129). CONCLUSION: This series of an 18-year duration emphasizes the severity of surgery for acute complications in diverticular disease of the colon and the advantages of elective surgery. Large progress in the management of peritonitis and pericolic abscesses has made possible the improvement of their prognosis.
