RESUMO

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.

OBJETIVOS: La hipertensión portal clínicamente significativa (HPCS), si bien no representa una contraindicación para la resección hepática en la cirrosis, se considera un factor pronóstico determinante en los resultados posoperatorios. Este estudio se propone de estudiar los efectos de la HPCS en los resultados a corto y largo plazo tras la resección hepática por carcinoma hepatocelular (CHC). MÉTODOS: Análisis retrospectivo mono-céntrico de 126 resecciones hepáticas por CHC en pacientes Child-Pugh A, realizadas entre el 2008 y el 2018. Los pacientes se han dividido según la presencia de HPCS, definida como gradiente de presión venoso hepático ≥ 10 mmHg. Para controlar el sesgo de selección, 42 pacientes con HPCS se han apareado con puntaje de propensión con 42 pacientes sin HPCS. RESULTADOS: La tasa de descompensación hepática fue 4 veces superior en los pacientes con HPCS (28.6% vs. 7.1%, p = 0.010), mientras las complicaciones graves, incluyendo la mortalidad a 90 días, no se mostraron diferentes en los pacientes con y sin HPCS. La supervivencia global y libre de recidiva no fueron inferiores en los pacientes con HPCS comparados. CONCLUSIONES: El presente estudio ha demostrado resultados aceptables en la resección hepática en pacientes con cirrosis Child-Pugh A cuidadosamente seleccionados, también en presencia de hipertensión portal.

RESUMO

AIM: To study the prevalence, characteristics, risk factors and mortality at 28 d of acute-on-chronic liver failure (ACLF). METHODS: A total of 100 cirrhotic patients admitted to our hospital for more than one day were included during the period between June 2013 and December 2015. We used the European Association for the Study of the Liver-Chronic Liver Failure-Consortium diagnostic criteria for ACLF, considering it as the acute decompensation of cirrhosis associated with the presence of one or more organ failure. For the diagnosis of organic failure the Chronic Liver Failure-Sequential Organ Failure Assessment score was used. Our population was divided into patients with and without ACLF. Clinical characteristics, presence of precipitating events, potential risk factors for developing ACLF and causes of mortality were analyzed. Mortality at 28 d was evaluated. RESULTS: Twenty-nine patients (29%) developed ACLF criteria. Alcoholism, detected in 58 patients (58%), was the major etiological agent of cirrhosis. Bacterial infections were recognized as a precipitating event in 41.3% of cases and gastrointestinal bleeding in 27.5%. No precipitating event was identifiable in 27.5% of patients with ACLF. Comparing patients with and without ACLF, statistically significant risk factors were: Child Pugh score 10.2 ± 2.1 vs 8.4 ± 1.6 (P ˂ 0.0001), MELD score 20.7 ± 8.5 vs 12.3 ± 4 (P ˂ 0.0001), presence of ascites 27 (93%) vs 43 (60.5%) (P = 0.001), leukocytosis 15300 ± 8033 per cubic millimeter vs 10770 ± 5601 per cubic millimeter (P ˂ 0.0001), and high plasma levels of C reactive protein values 50.9 ± ​​46.4 mg/L vs 28.6 ± 23.4 mg/L (P ˂ 0.0019). Mortality rate was 62% (18 patients) vs 5.6% (4 patients), respectively (P < 0.0001). CONCLUSION: We observed that the ACLF is a frequent entity in this group of patients and has a significantly higher mortality rate.
