Transvaginal Electromechanical Fragmentation and Removal of Large Uterus in a Sealed Bag: The First Group of Clinical Studies Balancing Scar - Free and Anti - Dissemination
Conditions: Uterine Fibroids, Adenomyosis, Enlarged Uterus
Sponsor: Chang Zhou

STUDY PROTOCOL
Official Title: Transvaginal InBag Electromechanical Morcellation for Extraction of Large Uteri
During Total Laparoscopic Hysterectomy
NCT Number: Pending
Document Date: March 2026
Background
This study evaluates a novel transvaginal specimen extraction technique using a sealed containment bag
combined with electromechanical morcellation during laparoscopic hysterectomy for large uteri.
Study Design
Singlecenter interventional surgical cohort study.
Primary Outcome
Containment bag integrity assessed using methylene blue leakage testing immediately after specimen
extraction.
Secondary Outcomes
Specimen extraction time, operative time, intraoperative blood loss, postoperative complications, and
length of hospital stay.
Eligibility Criteria
Women undergoing total laparoscopic hysterectomy for enlarged uteri (>12week size).
