Long-term outcomes of modified laparoscopic sacrocolpopexy for advanced pelvic organ prolapse: a 3-year prospective study.

Objective: The aim of the study was to evaluate the anatomical and functional outcomes of modified laparoscopic sacrocolpopexy (MLSC) for the treatment of advanced pelvic organ prolapse (POP).

Methods: From May 2009 to September 2012, a consecutive prospective observational study of 30 participants was conducted to evaluate MLSC as a treatment for symptomatic advanced POP at Peking Union Medical College Hospital. The Pelvic Organ Prolapse Quantification (POP-Q) classification was used to determine the POP stage. Validated tools were used to evaluate symptoms (Pelvic Floor Distress Inventory, PFDI-20) and sexual function (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, PISQ-12). Measurements were recorded preoperatively and then at 3 months and yearly after surgery. We compared the follow-up results with the preoperative data.

Results: All participants completed a 3-year clinical follow-up routine. The anatomical results at 3 months showed significant improvements (P < 0.05) compared with the preoperative results based on the POP-Q measurements. This improvement remained significant after 3 years (P < 0.05). The anatomical cure rate was 100% and 96.7% at 3 months and 3 years after surgery, respectively. Pelvic floor function remained significantly improved after surgery compared with preceding surgery (P < 0.05) according to the following measures: PFDI-20 (106.2 vs 36.0), Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6, 47.9 vs 13.7), Colorectal-Anal Distress Inventory-8 (CRADI-8, 29.2 vs 9.2), and Urinary Distress Inventory-6 (UDI-6, 29.2 vs 13.2). The participants maintained a high level of sexual function (PISQ-12: 29.0 vs 35.1, P < 0.05). One case of mesh exposure (3.3%) and two cases of de novo dyspareunia (8.7%) were observed.

Conclusions: MLSC seems to be a safe and effective procedure that achieves good long-term anatomical and functional results.
