The anterior resection operation revisited.

In a ten-year clinical experience (1966-1976) with anterior resection of the rectum and rectosigmoid colon, automated Russian and American anastomosing instruments were used. Results of operation in 123 cases of benign and malignant colonic disease show a nil mortality and no serious morbidity. The technique described establishes a colorectal mechanical anastomosis without the need of preliminary purse-strings and with peritonealization of the staple line for added safety.
