Laparoscopic pelvic anatomy of nerve-sparing radical hysterectomy.
Many reports regarding nerve-sparing radical hysterectomy have been published. However, most reports have been based on systematic descriptions via laparotomy or cadaver dissection. The aim of this work was to describe the pelvic anatomy of nerve-sparing radical hysterectomy via laparoscopy, with specific focus on the inferior hypogastric plexus. This study is based on 125 patients with FIGO stage IB cervical cancer who had undergone laparoscopic nerve-sparing radical hysterectomies since 1999. The inferior hypogastric plexus was demonstrated via laparoscopy and was comprised of afferent fibers from the sacral root (S2, S3, and S4), sacral sympathetic ganglion, and hypogastric nerve, and efferent fibers forming its vesical, uterovaginal, and rectal branches. During the dissection of the posterior leaf of the vesicouterine ligament, various vesical veins were identified. If the cut edge of an inferior vesical vein was pulled medially with upward traction, the vesical branches of the inferior hypogastric plexus were exposed and these were divided into medial and lateral branches. The magnified view of laparoscopy made it possible to dissect nerves and vessels meticulously and to secure a clear resection margin during the dissection of the deep part of the cardinal ligament, uterosacral ligament, and posterior leaf of the vesicouterine ligament.
