Vaginal mesh erosion after abdominal sacral colpopexy

Area of Science:

• Urogynecology
• Pelvic reconstructive surgery
• Surgical outcomes and complications

Background:

• Vaginal mesh erosion is a known complication following pelvic reconstructive surgery.
• Different surgical approaches for sacral colpopexy may influence the risk of mesh erosion.
• Understanding comparative erosion rates is crucial for optimizing surgical techniques.

Purpose of the Study:

• To compare the prevalence and incidence of vaginal mesh erosion between abdominal sacral colpopexy and various sacral colpoperineopexy procedures.
• To evaluate the impact of vaginal suture or mesh placement in combined procedures on erosion rates.
• To determine the time to mesh erosion across different surgical techniques.

Main Methods:

• Retrospective analysis of 273 sacral vault suspensions performed between 1992 and 1999.
• Patients categorized into four groups: abdominal sacral colpopexy, abdominal sacral colpoperineopexy, and two combined vaginal-abdominal groups (vaginal suture or vaginal mesh).
• Survival analysis and Cox proportional hazards models used to assess erosion rates and time to erosion.

Main Results:

• Overall mesh erosion rate was 5.5%.
• Abdominal sacral colpopexy (3.2%) and abdominal sacral colpoperineopexy (4.5%) showed no significant difference in erosion rates.
• Combined procedures with vaginal suture (16%) and vaginal mesh (40%) had significantly higher erosion rates and shorter time to erosion compared to abdominal sacral colpopexy alone.

Conclusions:

• Combined vaginal-abdominal sacral colpoperineopexy, particularly with vaginal mesh placement, is associated with a substantially higher risk of mesh erosion.
• The time to mesh erosion is significantly shorter in combined vaginal-abdominal approaches compared to purely abdominal sacral colpopexy.
• Surgical technique involving vaginal component in sacral colpoperineopexy significantly impacts mesh erosion outcomes.
