In-Bag Morcellation as a Routine for Laparoscopic Hysterectomy

Area of Science:

• Gynecology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Laparoscopic hysterectomy carries a risk of disseminating unsuspected malignant cells through tissue morcellation.
• Contained morcellation techniques aim to mitigate this risk by enclosing the specimen within a bag during the procedure.

Purpose of the Study:

• To evaluate the safety and efficacy of routine in-bag morcellation during laparoscopic hysterectomy.
• To assess the technical success rate and potential for cell spread with the More-Cell-Safe system.

Main Methods:

• A consecutive cohort of 49 patients undergoing laparoscopic hysterectomy utilized routine in-bag morcellation.
• The More-Cell-Safe containment system was employed, and outcomes including operative time, specimen weight, and residual tissue were recorded.
• Peritoneal washings were analyzed for malignant or smooth muscle cells post-morcellation.

Main Results:

• No cases of unsuspected malignancy were identified.
• The technical success rate for contained morcellation was 93.9%.
• Morcellation time correlated with uterine volume and specimen weight but not BMI; peritoneal washings were negative for malignant cells.

Conclusions:

• Routine in-bag morcellation is a safe and effective method for laparoscopic hysterectomy, significantly reducing the risk of spreading unsuspected malignant cells.
• The More-Cell-Safe system provides reliable containment, with a high success rate and no evidence of cell dissemination in this cohort.
