Laparoscopic Resection of Deep Infiltrating Endometriosis Affecting the Sciatic Nerve: A Case Report of Neurolysis and Fertility Preservation

Abstract

Introduction:

Sciatic nerve endometriosis is a rare but debilitating form of deep infiltrating endometriosis (DIE) that typically presents with cyclical, refractory sciatica. Management requires meticulous surgical planning and a multidisciplinary approach to achieve both neurological relief and fertility preservation.

Case Presentation:

A 37-year-old nulligravid patient presented with severe, debilitating left-sided sciatica unresponsive to hormonal treatment. Transvaginal ultrasound and pelvic magnetic resonance imaging revealed a large nodule reaching the left obturator internus and piriformis muscles. A complete laparoscopic excision was performed. Complete excision of the nodule infiltrating the obturator internus muscle was achieved, followed by nerve neurolysis.

Conclusion:

Complete laparoscopic excision offers a safe and effective treatment for sciatic nerve endometriosis, providing excellent symptom relief. This video highlights the necessary anatomical landmarks and surgical technique for safe neurolysis in the context of DIE.
