Year: 2024

Abstract: Background Presence of background liver disease increases the post operative morbidity and mortality among patients undergoing liver resection for hepatocellular carcinoma (HCC). These patients need evaluation of background liver function and portal hypertension, in addition to the conventional risk assessment. The current study aims to look at the outcomes of liver resections performed for HCC cases comparing cohorts with conventional risk assessment (CA) and those with functional assessment (FA) of background liver. Method A retrospective study including all liver resections for HCC cases performed in our tertiary care hepatobiliary unit between 2013 and 2022 (10 years) was conducted. A pathway for liver functional assessment using Tc 99m Mebrofenate SPECT-CT, and portal pressures (cut-off values of 2.79/min/m2 and 10mmHg, respectively) was included in the departmental protocol in December 2018. Data on demographics, underlying degree of liver cirrhosis, types of liver resection and post-operative outcomes including post-hepatectomy liver failure (PHLF) were collected and reported using descriptive statistics. Results 200 liver resections, performed for HCC between 2013 and 2022, were divided into a conventional (126 patients) and functional (74 patients) assessment groups. Median age (68 years) was similar. Background liver cirrhosis was present in 27 (21%) vs 19 (26%) cases, and major resections were performed in 47 (37%) and 10 (13%) cases in the CA and FA groups respectively. In the CA group, 90-day mortality was 7% (compared to FA group (1%) (p=0.26). None of the patients in FA group was found to have PHLF whereas 3 patients each had PHLF grade B and C in the conventional group. Conclusion Formal functional assessment of the background liver by evaluating the function of future liver remnant and presence of portal hypertension helps in selection of patients for appropriate surgical treatment options and improve the post-operative outcomes.
