Abstract
This report summarizes experience with 19 posterior approaches to the rectum including nine trans-sacral (Kraske) and ten transsphineteric (Mason) procedures. This study included 12 men and 7 women, ranging in age from 18 to 89 years. Surgical indications included villous tumors in nine patients, various benign problems in four patients, primary carcinomas in three patients, and recurrent cancer in three patients. Eight complications developed in the 19 patients including: four fecal flstulae, two wound dehiscences, one rectal stricture, and one sacrococcygeal hernia. Spontaneous closure of the fecal fistulae occurred in two patients, and two patients required proximal colostomies. Fecal continence was achieved in 18 of the 19 patients. No patient died as a complication of the procedure. No recurrent tumors have developed. The conclusion is that a posterior approach to the rectum is a safe and effective procedure for various benign and for selected malignant conditions. It is particularly suitable for villous tumors that are too high for transanal resection and too low for transabdominal resection. It is an effective procedure for small, exophytic, mobile carcinomas of the lower 10 cm of the rectum in selected patients.
