Randomized trial investigates enhanced surgical access through extensive liver dissection in cadaveric models, suggesting improved outcomes.
Key Points
This research aims to assess whether advanced liver dissection techniques enhance surgical access to right posterior lesions during laparoscopic liver resections.
Performed dissections using a formalin-preserved cadaveric model to measure liver rotation.
Defined three key dissection steps focusing on ligaments and the inferior vena cava.
Measured rotation angles using 30 newtons of traction applied via the round ligament.
30 dissections conducted with progressive rotation angles measured at median values of 36°, 45°, 71°, and 87°.
Angulation gains observed between each surgical step included 9° [6-13], 19° [17-31], and 13° [10-21].
Negative correlation between liver weight and angle of rotation during later dissection steps.
