Trocar port metastasis
Pronunciation: TROH-kar port meh-TAS-tah-sis
Tumor implantation at laparoscopic trocar insertion sites following minimally invasive gastrointestinal cancer surgery.
Full Definition
Trocar port metastasis refers to the development of tumor deposits at the sites where laparoscopic trocars were inserted during minimally invasive gastrointestinal cancer procedures. This complication occurs when malignant cells are inadvertently seeded during trocar insertion or removal, or through pneumoperitoneum-induced tumor cell dissemination. The incidence varies by primary tumor type and surgical technique. Prevention strategies include proper trocar site management, wound protectors, and meticulous surgical technique. Documentation of port site locations and follow-up imaging protocols are essential for early detection.
Usage
Usage note: Hyphenate when used as a compound modifier (trocar-port metastasis recurrence).
