In tumor localization at the level of 7--12 cm aside from the anus the authors performed 168 abdominoanal resections of the rectum with descending of different portions of the left colon. Among these patients in 126 subjects descending of the sigmoid in the anal canal was performed, in 30 of the splenic angle of the transverse colon, and in 12 of a proximal portion of the descending left colon. Some characteristic features of surgery for descending of different portions of the left colon are described.
