Novel Surgical Technique of Liver Parenchyma Transection During Robotic-Assisted Liver Resection: "Trac & Pac".

ABSTRACT:

Background/purpose

A standardized liver parenchymal transection method in robotic-assisted liver resection has not yet been established, and the techniques used vary among institutions. We developed a novel transection technique for robotic-assisted liver resection termed "Trac & Pac," which uses maryland bipolar forceps with a gentle stroking motion and strategic traction to progressively expose and dissect the liver parenchyma.

Methods

We described the technical details of "Trac & Pac" and Evaluated its short-term outcomes (2022-2025), comparing them with those of conventional laparoscopic liver resection using the Cavitron Ultrasonic Surgical Aspirator (CUSA) (2018-2022).

Results

The robotic-assisted liver resection group included 26 patients who underwent robotic
