Intra-operative colonic irrigation in the management of left-sided large bowel emergencies

In a consecutive series of 93 patients who required emergency surgery for distal colonic lesions, 61 had primary bowel resection with immediate anastomosis after intra-operative antegrade colonic irrigation. The operative mortality was 8 per cent, anastomotic leakage rate 7 per cent and superficial wound infection occurred in 3 per cent of patients. The mean hospital stay was 13 days. Of the remaining 32 patients, 3 did not have a resection and 29 had a primary resection and end colostomy without anastomosis: bowel continuity was later restored in 17 of 28 survivors (61 per cent) but 11 (39 per cent) were left with a permanent colostomy. The hospital mortality in this group was 6 per cent, superficial wound infection rate 14 per cent and the mean hospital stay 26 days. The results of this study suggest that intra-operative colonic irrigation is an effective method enabling the surgeon to perform a primary anastomosis with reasonable safety after emergency resection of selected distal colonic lesions.
