[Proctectomy with external sphincter elements' preservation in surgery of low-ampullary rectal cancer]

Operational technique for the rectum tumors, localized at the level of dentate line, developed in the State center of coloproctology, allows preservation of external anal sphincter elements and thus, partial preservation of defecation control. Technique is described and proved, preliminary treatment results of 42 patients are analysed. The operation is oncologically effective (local recurrence rate 4,8%). Preservation of external sphincter elements has a high functional value in complex with "neorectum" and "neosphincter". A majority of operated patients can keep the stool, 80% of able-bodied patients continued their professional activities.
