parenchymal transection
The surgical division of organ tissue, particularly liver or pancreas, to achieve tumor removal while preserving functional tissue.
Full Definition
Parenchymal transection refers to the controlled surgical division of solid organ tissue, most commonly performed during hepatic or pancreatic resections. This technique involves cutting through the functional tissue of an organ using various methods including crush-clamp technique, ultrasonic dissection, or electrocautery. The goal is to achieve oncologically sound resection margins while maximizing preservation of remaining organ function. Careful attention to hemostasis and bile duct or pancreatic duct integrity is essential during the procedure.
Usage
Usage note: Specifically refers to cutting organ tissue, not merely separating or mobilizing structures.
