morcellation
Pronunciation: mor-sel-LAY-shun
Surgical technique involving fragmentation of tissue specimens for removal, generally contraindicated in suspected malignancies due to risk of tumor dissemination.
Full Definition
Morcellation is a surgical technique that involves mechanically fragmenting tissues into smaller pieces to facilitate removal through small incisions, commonly used in minimally invasive procedures. In oncologic surgery, morcellation is generally contraindicated when malignancy is suspected because fragmentation can lead to tumor cell spillage and dissemination throughout body cavities. This risk has led to significant changes in surgical practice, particularly in gynecologic oncology, where power morcellation of uterine specimens has been restricted due to concerns about spreading undiagnosed uterine sarcomas. When morcellation is necessary for benign conditions, containment systems may be used to prevent tissue spillage.
Usage
Usage note: Term carries significant oncologic safety implications; usage should emphasize contraindications in malignant disease.
