Post-orgasm pain associated with endometriosis and complete resolution of symptoms after laparoscopic en-bloc peritonectomy, a case report

Introduction and importance: We report a rare case of post-orgasmic pain associated with endometriosis of the left hypogastric nerve and posterior vaginal wall. It is not a typical symptom of dyspareunia and has not been frequently associated with endometriosis in previous reports.Case presentation: A 36-year-old woman presented with post-orgasmic pain exclusively at orgasm, but no dys-pareunia during intercourse. She also reported bladder irritation and secondary dysmenorrhea.Clinical discussion: Physical examination revealed a small mass on the posterior vaginal wall and thickening of the left uterosacral ligament (USL) associated with severe pain. Pelvic magnetic resonance imaging (MRI) revealed endometrial tissue infiltration of the USL, hypogastric nerve tract, and posterior vaginal wall, consistent with endometriosis. Laparoscopic surgical excision was performed. Complete en bloc peritonectomy excision of the posterior pelvic compartment and complete removal of the lesions identified on MRI was performed. There were no postoperative complications and symptoms resolved completely. Histopathological examination revealed endometriosis.Conclusion: Orgasm-associated pain is rarely associated with endometriosis of the hypogastric nerve. In most cases there is no obvious cause for this symptom in this type of dysorgasmia. The complete resolution of symptoms after removal of the endometriosis by peritonectomy of the posterior pelvic compartment and en bloc excision strongly suggests a causal relationship between endometriosis of the hypogastric nerve and the orgasmic pain and urinary symptoms observed in this case. Also, the effective surgical technique used to treat endometriosis.
