Clinicians tend to overestimate liver remnant volume, increasing risk of liver failure post-surgery

Clinicians inaccurately estimate future liver remnant volume visually, tending to overestimate it, especially in cases with small remnants leading to higher risk of post-hepatectomy liver failure. Accuracy is lower for right hepatectomy (mean percent overestimation of 22%) and right trisectionectomy (mean percent overestimation of 25%), with specialists in hepatopancreatobiliary surgery having even higher overestimations. Experience level affects accuracy, with less experienced providers being more inaccurate in estimations.
