The role of surgical treatment in colon diverticulitis: indications and results.

PURPOSE Colon diverticulitis is a common illness with affects 37-45% of western populations. Indications regarding therapy guidelines, operative timing and which surgical procedure to perform are still controversial. MATERIAL AND METHOD Between January 1977 and December 1997, 239 patients, diagnosed with diverticulitis, have been admitted, on emergency, to our Department of General Surgery; 135 males (56%) and 104 females (44%), (mean age of 63 years). RESULTS AND DISCUSSION Forty-two patients (18%), clearly diagnosed with diffuse or local peritonitis, underwent delayed emergency surgical procedure; 44 (22%) out of 197 patients, treated with medical therapy and subsequently underwent elective surgery procedures for complications (fistulas or stenosis). Among the 42 patients treated in emergency, 26 cases (62%) underwent to resection with immediate reconstruction. Among the elective surgery group 39 (89%) out of 44 underwent to resection with immediate reconstruction. Complications reached 40% in the group of emergency patients (mortality rate 12%) and 16% in the elective surgery group (mortality rate 2%). Several features possible influencing mortality rate have been analysed; age > 70 years, acute associated diseases, generalised peritonitis and surgical timing show a statistical significance. CONCLUSION Therefore, a careful evaluation of the patients, an appropriate pre and post-operative medical treatment, with a wider use of the most recent techniques such as CT scan guided drain, intra-operative wash-out and peritoneal lavage are recommended in order to reduce morbidity and mortality.
