Pilsner Modification of Mesh Sacrohysterocolpopexy (PiMMS): An Initial Report on Safety and Efficacy.

INTRODUCTION AND HYPOTHESIS

It is reported that up to 60% of women would prefer to spare their uterus during pelvic organ prolapse (POP) repair surgery. A reliable hysteropexy technique is therefore crucial. We aimed to describe the safety profile and initial core patient-reported and clinical outcomes of the Pilsner modification of laparoscopic mesh sacrohysterocolpopexy (PiMMS) in comparison with the laparoscopic sacrohysterocolpopexy technique (standard laparoscopic sacrohysterocolpopexy [sLSH]) previously used in our unit.

METHODS

This was a retrospective cohort study conducted in a single tertiary referral urogynecological center. All patients who underwent laparoscopic mesh sacrohysterocolpopexy between 1 January 2015, and 31 January 2022 were included in the study. Follow-up clinical, patient-reported, and imaging outcomes at the 12-month follow-up time point are presented.

RESULTS

A total of 87 patients were included. Of these, 49 (56.3%) and 38 (43.7%) underwent sLSH and PiMMS respectively. Low numbers of perioperative complications were found in both groups with no mesh-related complications reported following PiMMS up to 12 months postoperatively. There were no apical compartment failures in either group. There were 8 (17.0%) vs 1 (2.7%) anterior compartment failures (Ba ≤ -1) in the sLSH and PiMMS groups respectively (p = 0.07) at 12 months. At the 1-year follow-up, 42 (89.4%) patients reported a Patient Global Impression of Improvement score of ≤ 2 in the sLSH groups compared with 35 (94.6%) patients following PiMMS.

CONCLUSIONS

The PiMMS technique seems to have comparable safety profile and patient-reported outcomes with the sLSH technique. However, there is a trend toward reduced anterior compartment failures with this modification. The findings of this preliminary report need to be re-evaluated in a well-powered prospective study.
