Laparoscopic Diagnosis and Treatment of Obturator Nerve Entrapment Because of a Deep Infiltrating Endometriotic Nodule: A Case Report

摘要

Deep infiltrating endometriosis (DIE) is a particular form of endometriosis causing a variety of severe pelvic pain in women. The involvement of peripheral nerves by DIE implants is very rare. The most common involved site is the sacral plexus. There are few reported cases of involvement of the obturator nerve by DIE. To our knowledge, only 6 cases of symptomatic obturator nerve involvement by DIE have been described (according to PubMed database search in July 2018), and 3 of them were treated laparoscopically. We report a rare case of a deep infiltrating endometriotic nodule entrapping the right obturator nerve. Unlike the previously reported cases, patient history, clinical and laboratory data, and missed findings in previous imaging studies made our case difficult to diagnose. We successfully diagnosed the case and treated the patient with laparoscopic surgery. A video showing the surgery is also included. The recent follow-up in July 2018 (18 months after the operation was performed in January 2017) showed no signs or symptoms of recurrence or any other new complaints. The 18-month follow-up for this case is the longest follow-up data reported in the literature. (C) 2018 AAGL. All rights reserved.
