Objective: Excisional techniques used to surgically treat deep infiltrating endometriosis (DIE) can result in inadvertent damage to the autonomic nervous system of the pelvis, leading to urinary, anorectal, and sexual dysfunction [1–4]. This educational video illustrates the autonomic neuroanatomy of the pelvis, identifying the predictable location of the hypogastric nerve in relation to other pelvic landmarks, and demonstrates a surgical technique for sparing the hypogastric nerve and inferior hypogastric plexus. Design: Using didactic schematics and medical drawings, we discuss and illustrate the autonomic neuroanatomy of the pelvis. With annotated laparoscopic footage, we demonstrate a stepwise approach for identifying, dissecting, and preserving the hypogastric nerve during pelvic surgery. Setting: Tertiary care academic hospitals: Mount Sinai Hospital in Toronto, Ontario, Canada, and S. Orsola Hospital in Bologna, Italy. Interventions: Radical excision of DIE with adequate identification and sparing of the hypogastric nerve and inferior hypogastric plexus bilaterally was performed, following an overview of pelvic neuroanatomy. The superior hypogastric plexus was described and the hypogastric nerve, the most superficial and readily identifiable component of the inferior hypogastric plexus, was identified and used as a landmark to preserve autonomic bundles in the pelvis. The following steps, illustrated with laparoscopic footage, describe a surgical technique developed to identify and preserve the hypogastric nerve and the deeper inferior hypogastric plexus without the need for more extensive pelvic dissection to the level of the sacral nerve roots: (1) transperitoneal identification of the hypogastric nerve, with a pulling maneuver for confirmation; (2) opening of the retroperitoneum at the level of the pelvic brim and retroperitoneal identification of the ureter; (3) medial dissection and identification of the hypogastric nerve; and (4) lateralization of the hypogastric nerve, allowing for safe resection of DIE. Conclusion: The hypogastric nerve follows a predictable course and can be identified, dissected, and spared during pelvic surgery, making it an important landmark for the preservation of pelvic autonomic innervation.

Abstract

Objective: Excisional techniques used to surgically treat deep infiltrating endometriosis (DIE) can result in inadvertent damage to the autonomic nervous system of the pelvis, leading to urinary, anorectal, and sexual dysfunction [1–4]. This educational video illustrates the autonomic neuroanatomy of the pelvis, identifying the predictable location of the hypogastric nerve in relation to other pelvic landmarks, and demonstrates a surgical technique for sparing the hypogastric nerve and inferior hypogastric plexus. Design: Using didactic schematics and medical drawings, we discuss and illustrate the autonomic neuroanatomy of the pelvis. With annotated laparoscopic footage, we demonstrate a stepwise approach for identifying, dissecting, and preserving the hypogastric nerve during pelvic surgery. Setting: Tertiary care academic hospitals: Mount Sinai Hospital in Toronto, Ontario, Canada, and S. Orsola Hospital in Bologna, Italy. Interventions: Radical excision of DIE with adequate identification and sparing of the hypogastric nerve and inferior hypogastric plexus bilaterally was performed, following an overview of pelvic neuroanatomy. The superior hypogastric plexus was described and the hypogastric nerve, the most superficial and readily identifiable component of the inferior hypogastric plexus, was identified and used as a landmark to preserve autonomic bundles in the pelvis. The following steps, illustrated with laparoscopic footage, describe a surgical technique developed to identify and preserve the hypogastric nerve and the deeper inferior hypogastric plexus without the need for more extensive pelvic dissection to the level of the sacral nerve roots: (1) transperitoneal identification of the hypogastric nerve, with a pulling maneuver for confirmation; (2) opening of the retroperitoneum at the level of the pelvic brim and retroperitoneal identification of the ureter; (3) medial dissection and identification of the hypogastric nerve; and (4) lateralization of the hypogastric nerve, allowing for safe resection of DIE. Conclusion: The hypogastric nerve follows a predictable course and can be identified, dissected, and spared during pelvic surgery, making it an important landmark for the preservation of pelvic autonomic innervation.
