Abstract
The exact incidence of colonic anastomotic breakdown in humans is difficult to assess. The low incidence reported on the basis of only clinical observation is misleading, since it was demonstrated that leakages occur without clinical manifestation. Better evaluation of the rate of incidence will require meticulous postoperative investigation. A new colonic anastomosis was performed in 24 cases of high and low anterior resections. The principle of forming a seromuscular cuff was employed.
