Localisation and preservation of the autonomic nerves in rectal cancer surgery - technical details.

Iatrogenic surgical injury to pelvic autonomic nerves followed by genitourinary dysfunctions are well known problems after total partial mesorectal excision for rectal cancer. The purpose of our paper is to present the useful anatomical landmarks for a safe nerve-sparing surgery in rectal oncology. Over the course of a total mesorectal excision we describe and illustrate the key risk zones of autonomic nerve injury based on our experience in rectal surgery and on the revised literature.
