[What is new in the surgical treatment of rectal cancer?].

Rectal adenocarcinoma is a common cancer. Substantial advances in surgical technique and adjuvant treatments usually allow to preserve sphincter function, without overruling oncologic surgery standards. Sexual function is usually preserved, except in patients with locally advanced tumors. There is sound evidence that complete removal of the mesorectum and local radiation therapy decrease the rate of local recurrences. Quality of functional results after colorectal versus coloanal anastomosis is compared, and the contribution to patient comfort of construction of a reservoir is evaluated.
