[Status of local excision of local deep rectal cancers with curative intention].

103 cases have been analyzed retrospectively to define the indication for local extirpation of small and deep-seated rectum carcinomas with curative purpose. While pedunculated carcinomatous adenomas can be removed by endoscopic loop extraction, the non-sessile polypous carcinomas have to be radically extirpated by excision from intestinal wall resection is a promising procedure. Here, the transanal access by means of a funnel-shaped, lateral fenestrated glass speculum as introduced by Dewey yields better results than the rectotomia posterior.
