title: [Sphincter-conserving surgery in tumors of the middle and distal rectum: methods, indications and limitations].
abstract: The purpose of this review is to summarize new developments in the surgical treatment of benign and malignant tumors of the rectum, focusing on oncological requirements and postoperative functional aspects which affect the quality of life. One of the developments is the transanal endoscopic microsurgical (TEM) approach to resection of adenomas and low risk early cancers in the rectum. Another focus is total rectum resection with colo-anal reconstruction with a colon pouch. This procedure reconstructs anorectal anatomy and provides nearly normal function. The reconstruction exists in two forms, (a) the colon-J-pouch and (b) the ileocecal interposition pouch (cecum pouch), which was developed at our institution. The review includes 33 consecutive patients with a rectum tumor. Standardized tumor-specific and functional staging determines which technique is used. 12 patients were operated on using the transanal endoscopic approach, 3 patients had a posterior proctotomy, another patient a transanal local excision and 17 patients total rectum resection with colon pouch reconstruction as described above.
