Low and ultra-low rectal resection: results and prospectives.

Abstract

We present our experience in the treatment of middle-lower rectal cancer particularly in reference to the use of those operative techniques which permit to save the sphincteric system. From 1990 to April 1995 seventy-two patients were operated on for middle-lower rectal cancer applying the Knight-Griffen technique. Such a method has already demonstrated the characteristics of a valid anastomosis, being simple, fast and safe. The introduction of stapler devices in the rectal surgery, particularly in its middle-lower tract has significantly modified the quality of life of such patients, reducing drastically the number of colostomies. The possibility to extend the rectal resection towards the anus with colo-anal anastomosis has showed a loco-regional recurrence rate not different from abdominal-perineal resection, even though with some sphincteric troubles due to incontinence. The satisfying surgical results obtained with low and ultra-low recta resections, by now widewordly accepted, should not anyway mask the importance of an early diagnosis as the main factor governing the prognosis (i.e. the overall mortality).
