Cholangiocarcinoma (CCA) arises from the biliary tract epithelium and accounts for 10–15% of all hepatobiliary malignancies. Depending on anatomic location, CCA is classified as intrahepatic (iCCA), perihilar (pCCA) and distal (dCCA). The best treatment option for pCCA is liver resection and when a radical oncological surgery is obtained, 5-year survival rate are around 20–40%. In unresectable patients, following a specific protocol, liver transplantation (LT) for pCCA showed excellent long-term disease-free survival rates. Fewer data are available for iCCA in LT setting. Nevertheless, patients with very early unresectable iCCA appear to achieve excellent outcomes after LT. This review aims to evaluate existing evidence to define the current role of LT in the management of patients with CCA.

In resected perihilar cholangiocarcinoma (PHC), positive ductal margin (DM) is associated with poor survival. There is currently little knowledge about the impact of positive radial margin (RM) when DM is negative. The aim of this study was to evaluate the incidence and the role of positive RM. Patients who underwent surgery between 2005 and 2017 where retrospectively reviewed and stratified according to margin positivity: an isolated RM-positive group and DM ± RM group. Of the 75 patients identified; 34 (45.3%) had R1 resection and 17 had positive RM alone. Survival was poorer in patients with R1 resection compared to R0 (p = 0.019). After stratification according to margin positivity; R0 patients showed better survival than DM ± RM-positive patients (p = 0.004; MST 43.9 vs. 23.6 months), but comparable to RM-positive patients (p = 0.361; MST 43.9 vs. 39.5 months). Recurrence was higher in DM ± RM group compared to R0 (p = 0.0017; median disease-free survival (DFS) 15 vs. 30 months); but comparable between RM and R0 group (p = 0.39; DFS 20 vs. 30 months). In univariate and multivariate analysis, DM positivity resulted as a negative prognostic factor both for survival and recurrence. In conclusion, positive RM resections appear to have different recurrence patterns and survival rates than positive DM resections.

Background: Hepatitis B virus (HBV) remains a leading etiology for liver transplantation (LT). In a large cohort of HBsAg-positive patients, this study evaluates long-term patient and graft survival after LT over the past 30 years while analyzing trends and outcomes following waiting list (WL) inclusion over the last 15 years. Methods: HBsAg-positive patients who underwent transplantation between 1991 and 2020 and were waitlisted from 2006 to 2020 at Padua Hospital were included in the analysis. Patients were stratified according to hepatitis delta virus (HDV) coinfection, transplant indication (decompensated cirrhosis vs. hepatocellular carcinoma (HCC)), and WL inclusion period. Results: Among 321 HBsAg-positive LT recipients (31.5% HDV-coinfected, 46.4% HCC), 1-year and 5-year patient/graft survival rates were 87.6%/86.7% and 82.6%/82.2%, respectively. From 2006 to 2020, 284 HBsAg-positive patients were waitlisted (32.6% HDV-coinfected), with a significantly higher prevalence of HCC compared to non-HBV patients (p = 0.008). High-barrier nucleos(t)ide analogues (hbNUCs) significantly reduced mortality (p = 0.041) and improved survival post-WL inclusion (p = 0.007). Survival rates were consistent regardless of LT indication, HDV coinfection, or WL inclusion period. Post-transplant prophylaxis predominantly involved immunoglobulins (HBIG) + NUCs, resulting in only two cases of HBV reactivation, both clinically inconsequential. Conclusions: Over the past 30 years, HBV has remained a consistent indication for LT at our center. Thanks to hbNUCs, WL outcomes have improved and HCC has become the main indication for LT.

Second opinion consultation is a well-established practice in different clinical settings of diagnostic medicine. However, little is known about second opinion consultation activity in transplantation, and even less is known about it concerning donor assessment. The consultations provided by the second opinion service led to the safer and homogeneous management of donors with a history of malignancy or ongoing neoplasm by transplant centers. Indeed, two of the most important aspects are the reduction of semantic differences in cancer reporting and the standardization of procedures, which are mainly due to the different settings and logistics of different pathology services. This article aims to discuss the role and the future of the second opinion in Italy during organ procurement, highlighting the critical issues and areas for improvement.

Novel direct antiviral-acting (DAA) molecules significantly improved efficacy and ameliorated outcomes of patients with chronic hepatitis C (CHC). The extensive use of DAA from 2015, due to large access to therapy, maximized rates of viral eradication with a safety profile in the majority of cases. Aims: We evaluated risk factors and the incidence of related clinical events and hepatocellular carcinoma (HCC) in cases with sustained virologic response (SVR) after DAA. We also aimed to apply a score assessment to identify the individual patient with unfavorable outcomes during an average follow-up (FU) of five years. Methods: In total, 470 cases consecutively recruited with CHC have been compared by non-invasive tests (NIT), as APRI, FORNS, FIB-4, LSPS, and transient elastography (TE) liver stiffness measurement (LSM), to identify cutoff related to major event onset. Results: Grouping of cases without or with related events development of both types hepatic (HE) (i.e., HCC or further cirrhosis decompensation or/with hospitalized septic state) or extrahepatic (EHE) (i.e., other tumors, bleeding, or thrombotic episodes and other organs pathologic conditions not liver related)allowed us to select the parameters to propose a novel risk stratification system (RISS) for the identification of the remnant individual patient’s risk for HCC occurrence, orthotopic liver transplant (OLT) need, or death during long-term follow-up (FU). Conclusions: Patients with cirrhosis and portal hypertension (PH) maintained a higher LSM mean value (>25 kPa), showed the lowest reduction of NIT scores, and developed events in 80/108 (74%) cases (67 and 13 of HE and EHE type), even after long-term successful DAA therapy. Furthermore, cases with RISS score ≥ 8 demonstrated a significant incidence of HCC (37/46, 80.4%) and a reduction in survival rate to 65.4% at 5-year FU.

Background: The movement of endemic diseases from tropical and disadvantaged areas is gradually spreading to developed countries as well. Amoebiasis, in particular, represents a significant threat to public health, amplified by globalization and increasing contact between humans and animals or vectors. In this way, atypical diseases may emerge in our country, also through an unusual mode of transmission—likely sexual, as “sexually transmitted enteric (STE) diseases”. Objective: We report and discuss the clinic approach to a rare case of dual human infestations by ecto- and endo-parasites with multiple liver abscesses presentation in a young truck driver residing in Northern Italy. Methods: The patient underwent a comprehensive screening with laboratory and microbiological tests, and CT images. Results: In July, the patient was admitted to our hepatology unit following the ultrasound identification of two hypoechoic lesions in the right lobe of the liver. In his medical history, in April, after a seemingly harmless infestation of body lice, effectively treated, he suffered from a prolonged and debilitating episode of acute diarrhea, lasting a month. This status was also accompanied by intestinal cramps, weight loss, and recurring fever episodes. Afterwards also appeared a Quincke’s-like angioedema involving the lips and mouth mucosa, with evening time exacerbation. Conclusions: The differential diagnosis of this complex and unusual clinical picture, together with the temporal evolution of the patient’s signs and symptoms, led us to hypothesize the presence of concomitant infections. These were most likely borreliosis and a STE disease, the latter ultimately diagnosed as amebiasis with hepatic invasion, allowing appropriate treatment and a favorable clinical outcome.
