Comparability of perioperative morbidity between abdominal myomectomy and hysterectomy for women with uterine leiomyomas.
OBJECTIVE
The aim of this study was to compare the perioperative morbidity associated with abdominal myomectomy with that of hysterectomy.


METHODS
This was a retrospective cohort study of 394 women at an academic medical center. Main outcome measured was perioperative morbidity, with the following secondary outcomes: febrile morbidity, hemorrhage, unintended major surgical procedures, life-threatening events, and rehospitalization.


RESULTS
Morbidity was associated with myomectomy and hysterectomy in 39% and 40% of cases, respectively. The crude odds ratio for morbidity of myomectomy with respect to hysterectomy was 0.93 (95% confidence interval, 0.63-1.40). Women who underwent myomectomy were significantly younger, weighed less, and had a smaller preoperative uterine size. In a multivariable analysis that accounted for these differences the odds ratio increased to 1.46 (95% confidence interval, 0.77-2.77) but still was not statistically elevated. The study had >90% power to detect a clinically relevant 15% absolute difference in overall morbidity between the 2 groups.


CONCLUSIONS
No clinically significant difference in perioperative morbidity between myomectomy and hysterectomy was detected. Myomectomy should be considered a safe alternative to hysterectomy.
