Abstract
Background: Despite conventional attitudes that interdict sphincter-preservation surgery (SPS) for cancers arising in the terminal 3 cm of rectum, we have selectively employed high-dose preoperative external radiation (HDPER) and either radical or local excisional SPS techniques for rectal cancer arising between the 0.5 and 3 cm levels above the anorectal ring. We have reported a preliminary experience with HDPER and full-thickness local excision (FTLE) and three different methods of radical SPS. We now describe our experience with a single method of radical excision, transanal abdominal transanal proctosigmoidectomy with coloanal anastomosis (TATA) and FTLE in conjunction with HDPER for cancers of the distal 3 cm of rectum based on specific guidelines.
