INDICATION AND SURGICAL TREATMENT OF ACUTE AND COMPLICATED DIVERTICULITS

Abstract

Although the surgical treatment of acute and complicated diverticulitis has been refined over the years, discussion is still ongoing about whether a single or two stage procedure (Hartmann’s procedure) should be performed in patients with peritonitis from perforation of a colonic diverticulum. A retrospective review was completed for patients undergoing surgery for acute complicated diverticulitis from 1980 to 1997. All patients were categorized according to Hinchey classification. Of the 186 patients treated, emergency operation was performed in 52 (28 per cent; group I ) and an elective operation in 134 (72 per cent; group II).

All patients had a resection of the involved colon and anastomosis was performed using CEEA staplers. In the group I, 50 patients underwent resection with immediate recostruction with or without colostomy and two an Hartmann’s procedure. Among the group II, primary anastomosis with or without proximal diversion was performed in 132 patients; two patients underwent an Hartmann’s procedure. Post-operative mortality was of 5,76 % in the group I and 2,9 % in the group II. Nine anastomotic leaks occurred in the group I and 18 in the group II.

Comparing these results with the recent literature, we have concluded that primary resection is virtually always possible in acute and complicated diverticulitis. Primary anastomosis with or without colostomy, in expert hands, is a safe procedure for patients in stage I of Hinchey’s classification or II, but should be considered on an individual basis in presence of peritonitis. In case of fecal peritonitis, persistent hypotension, ascites, severe immune compromise and extreme malnutrition the Hartmann procedure represent the procedure of choice.
