Indications for morcellation in gynecologic surgery

Area of Science:

• Gynecologic Surgery
• Minimally Invasive Procedures
• Surgical Oncology

Background:

• Laparoscopic hysterectomy and myomectomy frequently involve tissue morcellation.
• Myometrial cells can persist in the abdomen and pelvis post-myomectomy, regardless of morcellation.
• Distinguishing leiomyosarcoma (LMS) from benign fibroids preoperatively is challenging.

Purpose of the Study:

• To review the necessity and implications of tissue morcellation in minimally invasive gynecologic surgery.
• To address concerns regarding cancer spread during morcellation of presumed benign fibroids.
• To emphasize the importance of complete residual disease removal in gynecologic procedures.

Main Methods:

• Review of current literature on tissue morcellation in laparoscopic gynecologic procedures.
• Analysis of myometrial cell dissemination and residual disease following myomectomy.
• Discussion of leiomyosarcoma (LMS) characteristics and surgical management.

Main Results:

• Residual myometrial cells are present post-myomectomy, with or without morcellation.
• Containment bags are not essential for removing residual tissue; meticulous cleaning is effective.
• The concern of 'cutting-through' cancer is often overstated and irrelevant for LMS in minimally invasive gynecologic surgery.
• Complete removal of all tissue and cells from the abdominal and pelvic cavity should be the primary surgical goal.

Conclusions:

• Tissue morcellation is often required for women undergoing laparoscopic myomectomy or hysterectomy for symptomatic fibroids.
• Leiomyosarcoma (LMS), though rare, has a poor prognosis due to early metastasis and high recurrence rates.
• The priority in minimally invasive gynecologic surgery, including procedures involving morcellation, is the complete elimination of residual disease.
