Postoperative Outcomes after Surgery for Deep Endometriosis of the Sacral Plexus and Sciatic Nerve: A 52-patient...

To assess 1-year postoperative outcomes of surgery for deep endometriosis involving the sacral roots and sciatic nerve.

Retrospective case series.

Three referral centers.

Fifty-two women.

Surgery for deep endometriosis involving the sacral roots and sciatic nerve.

Deep endometriosis involved the sacral roots in 49 women (94.2%) and the sciatic nerve in 3 cases (5.8%). Sciatic pain (buttock or leg) was recorded in 43 women (82.7%), pudendal neuralgia in 11 women (21.2%), and leg motor weakness in 14 cases (27%). The surgical procedures carried out on the pelvic nerves included complete release and decompression (92.3%), excision of the epineurium by shaving (5.8%), and intraneural excision (1.9%). Additional major surgical procedures involved the digestive tract in 82.7% of the cases and the urinary tract in 46.2%. Rectovaginal fistula occurred in 13.5% of the cases. Self-catheterization was required in 14 cases (27%) at 3 weeks after surgery and in 3 women (5.8%) 12 months later. One-year follow-up showed significant improvement in quality of life measured using the Short-Form 36 questionnaire and standardized gastrointestinal scores. De novo hypoesthesia, hyperesthesia, or allodynia were recorded in 9 women (17.2%). The cumulative pregnancy rate was 77.2%% after natural conception in 47%.

Laparoscopic management of deep endometriosis involving the sacral roots and sciatic nerve improves patients' symptoms and overall quality of life. Although pain reduction may be rapid after surgery, other sensory or motor complaints, including bladder dysfunction, may be recorded over months or years.
