Complications of obliterative versus reconstructive vaginal surgery for pelvic organ prolapse in octogenarians: A retrospective cohort study

Aims: Women of advanced age may choose between restorative or obliterative surgery for surgical management of pelvic organ prolapse. Obliterative surgery is traditionally reserved for a subset of older women with more severe medical comorbidities, since obliterative approaches are generally considered to be less morbid and older individuals have higher rates of perioperative complications than younger cohorts. This study compared perioperative complications amongst octogenarians undergoing obliterative versus reconstructive approaches. This data will help to inform perioperative counselling as previous studies have not been powered to evaluate complications in this population. Methods: The National Surgical Quality Improvement Program database was used to identify patients that had Pelvic organ prolapse surgery between 2012 and 2021, aged 80 years or older. Single-compartment procedures, vaginal mesh procedures, and oncologic surgery were excluded. The primary outcome was any complication within the first 30 days excluding urinary tract infection (UTI). UTI, readmission, and severe complications were secondary outcomes. Results: Of the 4149 patients identified, 2514 (60.6%) underwent reconstructive surgery and 1635 (39.4%) underwent obliterative surgery. Patients undergoing reconstructive surgery were more likely to have an American Society of Anesthesiologists (ASA) class of 1 or 2 (46.1% vs. 31.3%, p = 0.002) and were less likely to be on antihypertensive medication (72.0% vs. 75.8%, p = 0.006). Further, there was an increased length of stay (1.47 +/- 1.84 vs. 1.03 +/- 1.31 days, p < 0.001) in hospital for reconstructive surgery which was more often performed as an inpatient (45.7% vs. 37.9%, p < 0.001). There was no difference in the primary outcome: any complication excluding UTIs. However, UTI was more common in the reconstructive group (aOR 0.48; 95% confidence interval 0.34-0.0). The rate of serious complications (Clavien-Dindo Class IV) was low overall and not different between reconstructive and obliterative approaches (1.3% vs. 1.0%, respectively). Conclusions: Both vaginal reconstructive and obliterative approaches have low complication rates in octogenarians, with only UTI rate being different between cohorts. When choosing surgical approach, we suggest a case-based, patient center discussion on the anatomic outcomes, durability and patient satisfaction.
