One hundred and eighteen patients undergoing low colorectal anastomoses were randomly allocated to reconstitution by either single layer interrupted extramucosal sutures or circular staple gun. In the 60 patients undergoing sutured anastomosis there were 2 (3 per cent) clinical leaks and 4 (7 per cent) radiological leaks, and no failures. Of the 58 patients who underwent stapled anastomosis there were 4 failures, 7 (12 per cent) clinical leaks, 14 (24 per cent) radiological leaks and 1 death. Stapled anastomoses were more than ten times as expensive as sutured anastomoses and there were no savings in time or numbers of associated colostomies. An interrupted extramucosal suture technique remains the ultimate standard for low colorectal anastomosis.
