A new type of abdomino-transanal resection of the rectum instead of its extirpation is being applied in tumors localized in the proximal part of the lower one third of rectum (5-6 cm from the anorectal line). For removing the whole lymph collector of the lower one third of the rectum the authors remove the levator tunnel as well. What remains intact is only the anal mucosa and the external anal sphincters. The anastomosis is realized by preliminary placing all catgut. Prophylactic transversostoma is also an obligatory procedure, so that the anal sphincters may remain at rest for 2-3 months after the operation. During this time the anal sphincters and the neorectum are fixed to the adjacent tissues and the anal tonus is fully restored. This operation was applied in 15 patients with very good result, as regards anal continence, without any case of relapse of the tumor so far.
