port site metastasis
Tumor recurrence at trocar insertion sites following laparoscopic surgery for cancer.
Full Definition
A rare but serious complication where malignant cells implant and grow at the abdominal wall sites where laparoscopic ports were inserted during minimally invasive cancer surgery. Port site metastases can occur through direct tumor cell implantation during specimen extraction or through pneumoperitoneum-related dissemination. While uncommon, this complication has important implications for surgical technique, specimen extraction methods, and patient counseling regarding laparoscopic approaches for certain gynecologic malignancies.
Usage
Usage note: Use singular 'metastasis' for individual occurrence, 'metastases' for multiple sites.
