Staples or sutures for colonic anastomoses--a controlled clinical trial.

We randomly allocated 100 patients undergoing colonic or rectal resections to have their anastomoses made either by a single layer of braided polyester interrupted sutures, or by the SPTU circular stapling instrument. Twelve anastomoses leaked, 4 being detected only by contrast enema. There was no difference in leak rate between the two anastomotic methods, but patients in the stapled group had a significantly higher incidence of minor wound infection, and spent significantly more days in hospital after operation. The stapling instrument is no safer than sutures for colonic and rectal anastomoses, but considerably facilities the performance of a low anterior resection.
