Perioperative Complications and Cost of Vaginal, Open Abdominal, and Robotic Surgery for Apical Vaginal Vault Prolapse.

Objectives: To determine the rate of perioperative complications and cost associated with Mayo-McCall culdoplasty (MMC), open abdominal sacrocolpopexy (ASC), and robotic sacrocolpopexy (RSC) for posthysterectomy vaginal vault prolapse.

Methods: We retrospectively searched for the records of patients undergoing posthysterectomy apical vaginal prolapse surgery (MMC, ASC, or RSC) between January 1, 2000, and June 30, 2012, at our institution. For all patients identified, perioperative complications, length of hospital stay, and inpatient costs to patients were abstracted from the medical records and compared by procedure. Inverse-probability-of-procedure weighting using propensity scores was used to obtain less-biased comparisons of outcomes between procedures.

Results: A total of 512 patients met the inclusion criteria (174 MMC, 237 ASC, and 101 RSC). Using inverse-probability weighting, the MMC group had a significantly lower intraoperative complication rate (3.3% vs 11.6% for ASC, 3.4% vs 24.1% for RSC), median operative time (94 vs 217 min for ASC, 100 vs 228 min for RSC), and median cost (US $8,776 vs $12,695 for ASC, US $8,773 vs $13,107 for RSC) than the ASC and RSC groups (all P < 0.01). In addition, the MMC group had significantly fewer postoperative grade 3+ complications than the RSC group (1.1% vs 9.4%, P < 0.01).

Conclusions: In the treatment of posthysterectomy vaginal vault prolapse, MMC is associated with decreased non-urinary tract infection, less perioperative morbidity, and lower cost to patients compared with sacrocolpopexy.
