margin re-excision
Additional surgical removal of tissue following initial resection when pathological margins are found to be positive or inadequate.
Full Definition
Margin re-excision is a secondary surgical procedure performed when the initial pathological examination reveals positive, close, or otherwise inadequate margins following tumor resection. This procedure involves returning to the operative site to remove additional tissue from the areas where margins were compromised, aiming to achieve clear margins and reduce the risk of local recurrence. The decision for re-excision depends on tumor type, location, margin distance, patient factors, and the availability of alternative treatments such as radiation therapy. Re-excision can be technically challenging due to altered anatomy from the initial surgery, tissue inflammation, and difficulty identifying the exact location of previous resection margins. Success is measured by achieving negative margins while preserving function.
Usage
Usage note: Hyphenate the compound term; specify which margins require re-excision.
