Combined preoperative albumin bilirubin score and hepatectomy percentage for evaluate the liver regeneration after partial hepatectomy

Abstract

Surgical resection is a pivotal therapeutic approach for addressing hepatic space-occupying lesions, with liver volume restoration and hepatic functional recovery being crucial for assessing surgical prognosis. The preoperative albumin-bilirubin (ALBI) score, encompassing serum albumin and bilirubin levels, can be determined via blood analysis, effectively mitigating human error and providing an accurate depiction of liver function. The hepatectomy ratio, which is the proportion of the liver volume removed to the total liver volume, is critical in preserving an adequate liver tissue volume to ensure postoperative hepatic functional compensation, minimize surgical complications, and reduce mortality rates. Incorporating the preoperative ALBI score and hepatectomy ratio aids surgeons in assessing the optimal timing and extent of partial hepatectomy. The introduction of preoperative albumin bilirubin score and hepatectomy percentage is beneficial for the surgeons to evaluate the timing and magnitude of partial liver resection.

Core Tip: Preoperative albumin bilirubin score can visually indicate the reserve of liver function, which is one of the indexes to evaluate liver volume recovery after partial hepatectomy. Besides, the size of the removed portion of the liver is also critical for the recovery of liver volume. By combining these two methods, the surgeons can determine the size and timing of a partial liver removal.
