PH is a very rare disease,more common in adults,and when it affects the liver,it comes to the surgeon's attention only in an extremely urgent situation after the lesion's rupture with the resulting hemoperitoneum. This report describes the case of a 29-year-old woman affected by recurring abdominal pain. Computed tomography scans showed a hepatic lesion formed by multiple hypodense areas,which showed an early acquisition of the contrast during the arterial phase. Furthermore,it remained isodense with the remaining parenchyma during the late venous phase. We decided on performing a liver resection of segment Ⅶ while avoiding a biopsy for safety reasons. The histopathologic examination confirmed the diagnosis of focal PH. PH should always be considered in the differential diagnosis of hepatic lesions. Clinicians should discuss the possible causes and issues related to the differential diagnosis in addition to the appropriate therapeutic approach. The fortuitous finding of a lesion,potentially compatible with PH,requires elective surgery with diagnostic and therapeutic intents. The main aim is to prevent the risk of a sudden bleeding that,in absence of properly equipped structures,may have a fatal outcome.展开更多

METHODS: Data from 358 patients transplanted between 1989 and 2010 in two Italian transplant centers and with evidence of hepatitis C recurrence were analyzed. A χ2, Fisher's exact test and Kruskal Wallis' test were used for categorical and continuous variables, respectively. Survival analysis was performed at 10 years after transplant using the Kaplan-Meier method, and a log-rank test was used to compare groups. A P level less than 0.05 was considered significant for all tests. Multivariate analysis of the predictive role of different variables on 10-year survival was performed by a stepwise Cox logistic regression.RESULTS: The ten-year survival of the entire population was 61.2%. Five groups of patients were identified according to the virological response or lack of a response to antiviral treatment and, among those who were not treated, according to the clinical status(mild hepatitis C recurrence, "too sick to be treated" and patients with comorbidities contraindicating the treatment). While the 10-year survival of treated and untreated patients was not different(59.1% vs 64.7%, P = 0.192), patients with a sustained virological response had a higher 10-year survival rate than both the "non-responders"(84.7% vs 39.8%, P < 0.0001) and too sick to be treated(84.7% vs 0%, P < 0.0001). Sustained virological responders had a survival rate comparable to patients untreated with mild recurrence(84.7% vs 89.3%). A sustained virological response and young donor age were independent predictors of 10-year survival. CONCLUSION: Sustained virological response significantly increased long-term survival. Awaiting the interferon-free regimen global availability, antiviral treatment might be questionable in selected subjects with mild hepatitis C recurrence.展开更多

In this study, we assessed the accuracy of the 50/50 criteria (bilirubin >2.9 mg/dL and international normalized ratio >1.7 on postoperative day 5) and the Mullen criteria (bilirubin peak >7 mg/dL on postoperative days 1-7) in predicting death from hepatic failure in patients undergoing right hepatectomy only. In addition, we identified prognostic factors linked to intra-hospital morbidity and mortality in these patients. METHODS: One hundred seventy consecutive patients underwent major right hepatectomy at a tertiary medical center from 2000 to 2008. Nineteen (11.2%) patients suffered from liver cirrhosis. Univariate and multivariate analyses were performed to identify predictors of intra-hospital mortality, morbidity and death from hepatic failure. RESULTS: The intra-hospital mortality was 6.5% (11/170). Of the six patients who died from hepatic failure, one was positive for the 50/50 criteria, but all six patients were positive for the Mullen criteria. Multivariate analysis showed that male gender, hepatitis C (HCV), hepatocellular carcinoma, postoperative bilirubin >7 mg/dL and ALT<188 U/L on postoperative day 1 were predictive of death from hepatic failure in the postoperative period. Age >65 years, HCV, reoperation, andrenal failure were significant predictors of overall intra-hospital mortality on multivariate analysis. CONCLUSIONS: The Mullen criteria were more accurate than the 50/50 criteria in predicting death from hepatic failure in patients undergoing right hepatectomy. A bilirubin peak >7 mg/dL in the postoperative period, HCV positivity, hepatocellular carcinoma, and an ALT level <188 U/L on postoperative day 1 were associated with death from hepatic failure in our patient population.展开更多
