Anatomical basis for pelvic autonomic nerve preservation in total mesorectal excision of adult male / 国际外科学杂志

ABSTRACT

Objective To study the pelvic fascia related to pelvic autonomic nerve and detect the anatomical localization of pelvic autonomic nerve by marker in adult male.Methods Twelve pelvises of adult male harvested from cadavers were studied by dissection.Results Hypogastric nerve was embedded in the posterior leaf of the visceral pelvic fascia.Pelvic plexus was situated between vesicohypogastric fascia and visceral fascia.Pelvic nerve branch of seminal vesicle and prostate was located at the anterolateral part of Denonvilliers fascia.Sacral promontory,ureter,junction of Denonvilliers fascia,visceral fascia and seminal vesicle could be regarded as anatomical markers for pelvic autonomic nerve.Conclusion The anatomical characteristics of pelvic autonomic nerve can be used for protecting and isolating pelvic autonomic nerve in total mesorectal excision of adult male.
