Abstract
Purpose
Radical eradication of deep infiltrating endometriosis (DIE) is associated with a high risk of iatrogenic autonomic denervation and pelvic dysfunction. Our aim was to prospectively analyze peri-operative details and post-operative functional outcomes (in terms of pain relief and bladder, rectal, and sexual function) among women operated for DIE of the posterior compartment with nerve-sparing technique, using the visual analogue scale and validated questionnaires.
Methods
All women undergoing laparoscopic nerve-sparing eradicative surgery for DIE nodules of the posterior compartment ≥ 4 cm ± bowel resection were included. Pain scores [using Visual Analogue Scale (VAS) scores] were collected before surgery and 6 and 12 months after surgery. Functional outcomes in terms of bladder, rectal, and sexual function, were evaluated using validated questionnaires (i.e., ICIQ-UISF, NBD score, and FSFI) administered pre-operatively and 6 months after surgery.
Main results
A total of 34 patients were included. Twenty-eight (82.4%) of them had already undergone a previous abdominal surgery for endometriosis. Bowel resection was performed in 16 (47.1%) patients. Median VAS score levels of pelvic pain were significantly decreased after surgery both at 6 (median 3, range 0–7 and 2, 0–7, respectively) and at 12 months (3, 0–8 and 2, 0–7), compared to pre-operative levels (9, 1–10 and 3, 0–7, respectively) (p < 0.0001). No differences were found in terms of urinary function between pre- and post-operative ICIQ-SF questionnaires. In no cases, bladder self-catheterization was needed at the 6-and 12-month follow-up. Median NBD score was 3.5 (0–21) pre-operatively and 2 (0–18) after 6 months (p = 0.72). The pre-operative total FSFI score was 19.1 (1.2–28.9) vs. 22.7 (12.2–31) post-operatively (p = 0.004).
Conclusions
The nerve-sparing approach is effective in eradicating DIE of the posterior compartment, with satisfactory pain control, significant improvement of sexual function, and preservation of bladder and rectal function.
