Efficacy of In-bag Morcellation

Not Applicable

Completed

• Conditions: Hysterectomy, Vaginal; Uterine Myomatosis; Laparoscopy

• Registration Number: NCT03281460
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

Laparoscopic mini-invasive surgery supplanted laparotomy for many years, including hysterectomy or myomectomy (less postoperative complications compared to laparotomy) However the US Federal Drug Administration (FDA) strongly warned against the use of power morcellation in 2014 because of the risk of iatrogenic spread of malignant cells.

The hypothesis is that in-bag morcellation may prevent cells dissemination. The investigator compare in this prospective randomized study two groups of patients: group A (in bag-morcellation during laparoscopic myomectomy or hysterectomy) versus group B (morcellation without any bag during laparoscopic myomectomy or hysterectomy)
