Minimally Invasive Hysterectomy & Power Morcellation Use

Obstet Gynecol; ePub 2017 May 5; Zaritsky, et al

A high minimally invasive hysterectomy rate is primarily associated with uterine size and can be maintained without power morcellation use, a recent study concluded. The trend analysis and retrospective cohort study included women aged ≥18 years undergoing hysterectomy for benign conditions. Researchers found:

  • There were 31,971 hysterectomies from 2008 to 2015 with slight decrease in incidence.
  • Minimally invasive hysterectomies increased from 39.8% to 93.1% during the same study period.
  • Vaginal hysterectomies decreased slightly from 26.6% to 23.4%.
  • The proportion of nonrobotic laparoscopic hysterectomies with power morcellation increased steadily from 3.7% in 2008 to a peak of 11.4% in 2013 but then decreased to 0.02% in 2015.
  • Women with large uteri were more likely to receive abdominal hysterectomies than minimally invasive hysterectomy and laparoscopic hysterectomy with power morcellation than without power morcellation.
  • Laparoscopic supracervical hysterectomy was strongly associated with power morcellation use.
