[Transanal local tumorectomy]

Transanal tumorectomy is an operation with continuing anal continence. With necessary indications give, this operation is justified both curatively and palliatively. Sphincter-stretching in combination with a lateral sphincterotomy of the Musculus sphincter internus and externus to two thirds their height is performed. This technique allows the resection of tumors in the rectum up to 12 cm from the anocutaneous line, a height that cannot be reached by dilatation only. The results from the First Surgery Department of Innsbruck University show that in more than 50% of patients submitted to transanal tumorectomy, this expansion of the operational angle was necessary to remove tumors.
