[Interpretation of results of clinical studies for practical colon and rectum surgery]

Systemic antibiotic prophylaxis in surgery of the colon and rectum is principally useful. It should be administered only on the day of surgery. Stapling makes it possible to enlarge the indication for deeper rectal resection. In cases of deep rectal anastomoses in men bladder dysfunction has to be expected in a considerable percentage. Anal continence does not depend on the anastomotic technique but on the anastomotic level in relation to its distance from the ano-cutaneous line and in consequence on the loss of reservoir capacity.
