To assess perioperative outcomes and identify predictors of complications for minimally invasive surgery (MIS) myomectomy in a cohort of women with large and numerous myomata.DesignCase-control study (Canadian Task Force classification II-2).SettingAcademic tertiary care medical center.PatientsWomen undergoing MIS myomectomy performed by 3 high-volume surgeons between April 2011 and December 2014.InterventionsCharacteristics were compared between women who experienced complications and those who did not. Factors predictive of complications were then identified.Measurements and Main ResultsA total of 221 women underwent an MIS myomectomy, 47.5% via a laparoscopic approach and 52.5% via robotic surgery. The mean ± SD specimen weight was 408.1 ± 384.9 g, uterine volume was 586.1 ± 534.1 cm3, dominant myoma diameter was 9.6 ± 5.1 cm, and number of myomata removed was 4.5 ± 4.1. The most common complications were hemorrhage >1000 mL (8.6%) and blood transfusion (4.1%). The conversion rate was 1.8%. A dominant myoma diameter of ≥12 cm and a uterine volume of ≥750 cm3 increased the odds of complications (odds ratio [OR], 7.44; 95% confidence interval [CI], 2.03–31.84; p = .004 and OR, 6.15; 95% CI, 1.55–30.02; p = .014 respectively). A receiver operating characteristic curve considering dominant myoma diameter and uterine volume had an area under the curve of 0.81. A combination of dominant myoma diameter of ≥10 cm and uterine volume of 600 cm3 predicted complications with 79% sensitivity and 79% specificity.ConclusionOur cohort had large and numerous myomata with high specimen weights, but complications were comparable to those reported in previous studies of MIS myomectomy with less complex pathology. Hemorrhage and transfusion accounted for the majority of complications, and a combination of dominant myoma diameter and uterine volume was predictive of complications. Both factors can be easily defined before surgery and may be used to guide patient counseling, referrals, and implementation of preventative measures for hemorrhage and transfusion.
