OBJECTIVE: To report that isolated endometriosis of the sciatic nerve without further manifestation of endometriosis does exist. DESIGN: We describe our technique of laparoscopic neurolysis of the sciatic nerve and the sacral plexus. SETTING: Department of Gynecology and Obstetrics, St. Elisabeth Hospital, affiliated with the University of Cologne, Cologne, Germany. PATIENT(S): Three female patients with isolated endometriotic infiltration of the endopelvic portion of the sciatic nerve. INTERVENTION(S): Elective laparoscopic neurolysis of the sciatic nerve with removal of endometriosis. MAIN OUTCOME MEASURE(S): Disparition of pain in the patients and histologic information of the endometriosis. RESULT(S): Isolated endometriosis of the sciatic nerve and/or the sacral plexus does exist without any further endometriosis genitalis externa manifestations. CONCLUSION(S): In young patients with sciatica of an unknown genesis, an endometriosis of the sciatic nerve must be evoked, and a laparoscopic exploration of the sciatic nerve must be discussed.
