Abstract
Stapled anastomoses are currently an established technique in colorectal surgery. Larger series about the use of circular staplers in rectal anastomoses within daily clinical routine are rare. We evaluated the morbidity, clinical leakage rate, and mortality in an unselected population of a teaching hospital after elective, left-sided colorectal resections with stapled rectal anastomoses. In the course of our study, manually sewn rectal anastomoses were not performed. All anastomoses were tested intraoperatively by instillation of liquid. A total of 615 elective colorectal resections with stapled rectal anastomoses was performed by 18 surgeons from 1984 to 1993. A protective colostomy was created in 2.9 percent (n=16) of all patients. Clinical anastomotic leakage occurred in nine patients (1.5 percent). The mortality rate was 1 percent (n=6). Use of the stapling technique facilitates the performance of anastomoses, particularly in regions with difficult anatomy. The rate of local complications is low, and protective colostomy can thus be dispensed with in most cases.
