Background: Management of low rectal cancer continues to be a challenge, and decision making regarding the need for an abdominoperineal resection (APR) in patients with low-lying tumors is complicated. Furthermore, choices need to be made regarding need for modification of the surgical approach based on tumor anatomy and patient goals.
Discussion: In this article, we address patient selection, preoperative planning, and intraoperative technique required to perform the three types of abdominoperineal resections for rectal cancer: extrasphincteric, extralevator, and intersphincteric. Attention is paid not only to traditional oncologic outcomes such as recurrence and survival but also to patient-reported outcomes and quality of life.
