endoscopic mucosal resection
Also written as: EMR — Endoscopic Mucosal Resection
Minimally invasive technique for removing superficial lesions from hollow organs during laparoscopy.
Full Definition
A precise surgical technique combining laparoscopic and endoscopic approaches to remove superficial mucosal lesions from the gastrointestinal tract or other hollow organs. The procedure involves lifting the mucosa with saline injection, then using specialized endoscopic tools to resect the lesion while preserving the deeper layers of the organ wall. This approach is particularly valuable for treating early-stage cancers, large polyps, or other mucosal abnormalities that cannot be removed through standard endoscopic techniques alone.
Usage
Usage note: Commonly abbreviated as EMR; distinguish from deeper resection techniques.
