Impact and outcomes of liver resection for hepatocellular carcinoma in patients with clinically significant portal hypertension.

PURPOSE: Clinically significant portal hypertension (CSPH), although not a contraindication for liver resection in cirrhosis, is considered a determinant prognostic factor for post-surgical outcomes. This study aims to investigate the effects of CSPH on short and long-term results after hepatic resection for hepatocellular carcinoma (HCC).

METHODS

Single-center retrospective analysis of 126 consecutive hepatic resections for HCC in Child-Pugh A patients, performed between 2008 and 2018. Patients were divided according to the presence of CSPH, defined as a hepatic venous pressure gradient ≥ 10 mmHg. To overcome selection bias, 42 patients with CSPH were matched through propensity score with 42 patients without CSPH. Intraoperative and post-operative outcomes, along with overall and disease-free survival, were compared between the matched groups.

RESULTS

Liver decompensation was four-fold in the CSPH group (28.6% vs. 7.1%, p = 0.010), while rate of severe complications, including 90-days mortality, was not statistically different between patients with and without CSPH. Overall and recurrence-free survival was not inferior in patients with CSPH compared to non-CSPH group.

CONCLUSIONS

The present study has demonstrated acceptable outcomes of liver resection for HCC in carefully selected Child-Pugh A cirrhotic patients, even in the presence of elevated portal pressure.
