Transvaginal sacrospinous ligament suture rectopexy for obstructed defecation symptoms: 1-year outcomes

INTRODUCTION AND HYPOTHESIS: The current study was aimed at investigating the safety, efficiency, and durability of transvaginal sacrospinous ligament suture rectopexy in women with obstructed defecation symptoms (ODS) and significant rectal hypermobility/folding. METHODS: This was a prospective case series study performed during December 2018 to July 2020. Women presenting to our center with pelvic organ prolapse electing for surgical treatment were screened for ODS utilizing the PFDI-20 questionnaire. Patients were eligible for inclusion if they reported OD symptoms accompanying >50% of bowel movements (BMs), BM frequency ≥3 per week, stool type 3 or 4 based on the Bristol stool chart, absence of dyssynergic Valsalva, and dynamic ultrasound indicating a rectal compression ratio >25%. Patients underwent transvaginal sacrospinous ligament rectopexy and were followed up at 2 and 12 months postoperatively. RESULTS: A total of 20 patients underwent the procedure and completed the follow-up. Statistically significant improvements were observed in all OD symptoms and subjective improvement (94.7% ± 13.4 and 90.6% ± 18) at 2 and 12 months after the surgery respectively. Mean rectal compression ratio, detected via ultrasound, improved from 45.5% ± 18.4 preoperatively to 9.2% ± 13.7 at 2 months (p < 0.0001) and 19.6% ± 14.4 at 12 months (p < 0.0012). Surgical failure, defined as combined subjective (ODS >50% of bowel movements) and anatomical failure (rectal compression ratio >25%), occurred in 2 patients. CONCLUSION: Transvaginal sacrospinous ligament suture rectopexy was safe, feasible, and effectively treated ODS within this cohort of women undergoing POP surgery with rectal hypermobility confirmed by dynamic ultrasound.
