Objective:
To identify the prevalence of unexpected uterine sarcoma after myomectomy for presumed leiomyoma and compare clinical outcomes after primary myomectomy with and without power morcellation.
Methods:
In a retrospective study, a review was undertaken of the medical records of patients who had unexpected uterine sarcoma after myomectomy with and without power morcellation at Peking Union Medical College Hospital, Beijing, China, between January 2009 and December 2013.
Results:
Among 4248 patients who underwent myomectomy for presumed leiomyoma, 9 (0.2%) had unexpected uterine sarcoma (1 [<0.1%] had leiomyosarcoma; 8 [0.2%] endometrial stromal sarcoma). The malignancy was identified in 5 (0.2%) of 3068 women who were treated by laparoscopy with power morcellation and 4 (0.3%) of 1180 who underwent laparotomy (P=0.274). All nine patients were alive after a mean follow-up of 31.2 months in the laparoscopy group and 40.5 months in the laparotomy group.
Conclusion:
The overall incidence of unexpected uterine sarcoma after myomectomy was low. Incidental power morcellation of unexpected uterine sarcoma seemed to cause no increase in sarcoma dissemination.
