Power morcellators: a review of current practice and assessment of risk.

Power morcellation has come under scrutiny because of a highly publicized case of disseminated leiomyosarcoma following a laparoscopic hysterectomy. A recent Federal and Drug Administration safety communication discouraging use of power morcellators on presumed uterine leiomyoma further highlights the need for reexamination of uterine tissue extraction. This clinical opinion aims to summarize current approaches to uterine/fibroid tissue extraction including the associated immediate and long-term potential risks of open power morcellation. The known data about risk of uterine sarcoma is reviewed followed by a discussion of acceptable risk and informed consent in the context of shared-decision making.
