Contained tissue extraction using power morcellation: prospective evaluation of leakage parameters

Area of Science:

• Gynecologic Surgery
• Minimally Invasive Procedures
• Surgical Safety

Background:

• Minimally invasive hysterectomy and myomectomy pose challenges for safe tissue removal, especially concerning potential dissemination of undetected malignancy.
• Contained tissue extraction techniques aim to reduce risks associated with morcellation.

Purpose of the Study:

• To quantify perioperative outcomes of contained tissue extraction using power morcellation.
• To evaluate tissue or fluid leakage from within the containment system during these procedures.

Main Methods:

• A multicenter prospective cohort study of women undergoing minimally invasive hysterectomy or myomectomy.
• Utilized contained power morcellation with blue dye application to detect specimen spillage.

Main Results:

• 76 patients completed the protocol; mean morcellation time was 30.2 minutes.
• Specimen weights averaged 480.1g (hysterectomy) and 239.1g (myomectomy).
• 9.2% of cases showed dye or tissue spillage, with intact containment bags.

Conclusions:

• Contained tissue extraction using power morcellation is feasible.
• Further refinement of this technique is recommended for enhanced safety and efficacy.
