Obesity and its long-term impact on sacrocolpopexy key outcomes (OBELISK).

Sacrocolpopexy is the preferred contemporary approach to managing significant apical pelvic organ prolapse. Obesity is an established risk factor for several surgical procedures and can have a negative impact on outcomes. Our goal was to evaluate the impact of BMI on the safety and efficacy of laparoscopic sacrocolpopexy in women with pelvic organ prolapse. A single-center retrospective observational study of women undergoing laparoscopic sacrocolpopexy between January 1, 2015, and December 31, 2017. We found 299 procedures: 82 (27.4%), 147 (49.2%) and 70 (23.4%) in women with BMI <25 (normal weight), BMI ≥ 25 - < 30 (overweight) and BMI ≥ 30 (obese), respectively. Perioperative and early postoperative complications were generally low and not statistically significantly different between the groups. At 12 months postoperatively, 81 (98.8%), 136 (92.5%) and 62 (88.6%) normal-weight, overweight and obese women attended their follow-up, respectively. All obese women attending the follow-up scored an overall Patient Global Impression of Improvement (PGI-I) of ≤ 3. The Pelvic Floor Distress Inventory (PFDI) scores showed a significant improvement in all domains and were similar between the study groups. In total, there was one (0.4%) anatomical apical compartment failure, three (1.1%) anterior compartment failures and two (0.7%) posterior compartment failures with no significant differences between the groups. Similarly, there were no differences in functional outcomes or mesh position as assessed by ultrasound. There were no differences in surgical, short- and long-term outcomes of laparoscopic sacrocolpopexy for pelvic organ prolapse in obese compared with non-obese women.
