A National Contemporary Analysis of Perioperative Outcomes of Open versus Minimally Invasive Sacrocolpopexy

Abstract

Purpose: We evaluated the perioperative morbidity of open abdominal sacrocolpopexy and minimally invasive sacrocolpopexy using data on a contemporary nationwide cohort.

Materials and methods: We used the ACS (American College of Surgeons) NSQIP® (National Surgical Quality Improvement Program) database to identify women who underwent abdominal or minimally invasive sacrocolpopexy from 2010 to 2016. Associations of surgical approach with 30-day complications, blood transfusion, prolonged hospitalization and reoperation were evaluated by logistic regression. Hospital readmission within 30 days was calculated by the person-years method and Cox proportional hazard models.

Results: A total of 4,362 women underwent sacrocolpopexy, including abdominal sacrocolpopexy in 1,179 (27%) and minimally invasive sacrocolpopexy in 3,183 (73%). The proportion of minimally invasive sacrocolpopexy increased during the study period from 70% in 2010 to 82% in 2016. Baseline characteristics were similar between the treatment groups aside from a higher rate of chronic obstructive pulmonary disease (p = 0.03) and higher preoperative albumin (p <0.0001) among abdominal sacrocolpopexy cases. Compared to abdominal sacrocolpopexy, minimally invasive sacrocolpopexy was associated with lower rates of 30-day complications (p = 0.001), deep vein thrombosis/pulmonary embolism (p = 0.02), surgical site infections (p <0.0001), shorter hospitalization (p <0.0001) and fewer blood transfusions (p = 0.01). Minimally invasive sacrocolpopexy was also associated with a lower 30 person-days readmission rate (2% vs 2.7%, p ≤0.0001) and 30-day reoperation rate (1.1% vs 1.4%, p <0.0001). On multivariable analysis minimally invasive sacrocolpopexy was independently associated with a reduced risk of 30-day complications (OR 0.46, 95% CI 0.28, 0.76, p = 0.002), blood transfusion (OR 0.33, 95% CI 0.15, 0.74, p = 0.007), prolonged hospitalization (OR 0.16, 95% CI 0.12, 0.23, p <0.001) and readmission (HR 0.62, 95% CI 0.41, 0.96, p = 0.03).

Conclusions: Minimally invasive sacrocolpopexy was associated with reduced rates of 30-day complications, blood transfusion, prolonged hospitalization and hospital readmission compared to abdominal sacrocolpopexy.
