Abstract:
Morcellation is the fragmentation of tissue to facilitate removal of the specimen through small incision in minimally invasive surgery. This technique is not unique to gynecology and is used in general surgery with the goal of improved surgical outcomes including decreased pain, cost, hospital length of stay, and rapid return to normal activities and work. Gynecologic laparoscopic power morcellation (LPM) has come under increased scrutiny over the last 2 years due to widespread attention to a known but rare complication, an unanticipated dissemination of malignancy, namely occult uterine leiomyosarcoma. This chapter focuses on complications associated with gynecologic tissue morcellation from inoculation of benign or malignant tissue fragments within the peritoneal cavity and direct trauma from morcellation techniques. We also include a review of the various morcellation techniques from knife to electrical and the use of intraperitoneal specimen containment systems.
Insights
Gynecologic laparoscopic power morcellation (LPM) offers benefits but carries risks of spreading benign or malignant tissue. This review examines morcellation complications and containment strategies to improve patient safety.
Area of Science:
- Minimally Invasive Surgery
- Gynecologic Oncology
- Surgical Pathology
Background:
- Morcellation, tissue fragmentation for removal via small incisions, is used in general and gynecologic surgery to improve outcomes.
- Gynecologic laparoscopic power morcellation (LPM) faces scrutiny due to rare but serious complications, including dissemination of occult uterine leiomyosarcoma.
- Complications involve peritoneal inoculation of benign/malignant tissue and direct surgical trauma.
Purpose of the Study:
- To review complications associated with gynecologic tissue morcellation.
- To discuss the risks of tissue dissemination and direct trauma during LPM.
- To present an overview of different morcellation techniques and containment systems.
Main Methods:
- Literature review of morcellation techniques and complications.
- Analysis of risks associated with gynecologic laparoscopic power morcellation.
- Evaluation of specimen containment systems for intraperitoneal use.
Main Results:
- Morcellation can lead to the spread of benign or malignant tissue within the peritoneal cavity.
- Direct trauma from morcellation instruments is another potential complication.
- Various morcellation devices (e.g., knife, electrical) and containment strategies exist.
Conclusions:
- Understanding and mitigating the risks of tissue dissemination are crucial for safe gynecologic morcellation.
- Intraperitoneal specimen containment systems offer a potential solution to reduce complication rates.
- Further research and standardized protocols are needed to optimize safety in LPM procedures.
