Modified laparoscopic sacrocolpopexy for advanced posterior vaginal wall prolapse: a 3-year prospective study.

Objectives: To evaluate and validate the safety and efficacy of modified laparoscopic sacrocolpopexy for advanced posterior vaginal wall prolapse at up to 3 years of follow-up.

Material and methods: As a prospective observational study, we collected 56 cases with advanced posterior vaginal wall prolapse and performed modified laparoscopic sacrocolpopexy (MLSC) with self-cut mesh. The main improvement is the cutting and fixing of the mesh. Patients were followed up at 6, 12, 24 and 36 months. The main indicators of follow-up were postoperative anatomic success rate and Pelvic organ prolapse quantitation (POP-Q) score, and secondary indicators were related to quality-of-life scales and postoperative complication rates.

Results: All patients completed the operation through minimally invasive surgery, and there were no vital organs and blood vessel damage during the operation. The mean age was (58.32 ± 7.63) years. There was no recurrence of stage I or lower during the follow-up maximum of 36 months (median 24 months), and the anatomic success rate was 100%. The quality-of-life scores improved significantly (p < 0.001) and the quality of sexual life was not affected (p = 0.5). There was 1 case of continuous vaginal mesh exposure at 12 months (2.86%) and 1 case of severe infection with poor healing of vaginal stump within 6 months (1.79%). No one had urinary incontinence (UI) requiring reoperation.

Conclusions: In patients with advanced posterior vaginal wall prolapse, MLSC can provide good and durable pelvic floor anatomical recovery and functional outcomes with no specific complications.
