Background: Biliary fistulas typically occur as surgical complications after laparoscopic cholecystectomy, liver transplantation, or partial liver resection.
Aims: This study aimed to evaluate the efficacy of the endoscopic treatment of biliary fistulae secondary to liver transplantation compared to that of other etiologies.
Methods: A retrospective study of 25 patients undergoing endoscopic retrograde cholangiopancreatography for biliary fistula from 2015 to 2021 was conducted at the Endoscospy Unit of Walter Cantídio University Hospital. Clinical characteristics and endoscopic success rates of the post-liver transplantation group were analyzed in comparison with those of other etiologies.
Results: The main causes of biliary fistula were liver transplantation (44%) and cholecystectomy complications (44%). The post-liver transplantation group had a significantly higher proportion of male sex (liver transplantation=81.8%, others=28.6%) and older age (liver transplantation=54.1 years, others=42.0 years) and a higher incidence of biliary stenosis (liver transplantation=90.9%, others=14.3%) than those of the group with other etiologies (p<0.05). The two groups received similar treatment types, among which sphincterotomy associated with biliary stent placement was most commonly used. Endoscopic therapeutic success rates showed no significant difference between the post-liver transplantation group (63.6%) and the group with other etiologies (71.4%).
Conclusions: The endoscopic treatment of biliary fistulae secondary to liver transplantation presented a recovery rate similar to that of other etiologies despite the patients older age and the presence of biliary stenosis.

Background: Hematopoietic stem cell transplantation (HSCT) is a common therapy for many hematologic malignancies. While advances in transplant practice have improved cancer-specific outcomes, multiple and debilitating long term physical and psychologic effects remain. Patients undergoing allogeneic bone marrow transplantation (allo-BMT) are often critically ill at initial diagnosis and with necessary sequential treatments become increasingly frail and deconditioned.

Primary sclerosing cholangitis (PSC) is associated with a high risk of hepatobiliary malignancy, especially cholangiocarcinoma (CCA). There are no good tumor markers to screen for CCA, and current recommendations for PSC monitoring are mainly based on expert opinions. The optimal strategy to assess disease progression and screen for CCA - the main cause of death of PSC patients - remains unclear.

Background: The treatment of advanced hepatocellular carcinoma (HCC) with atezolizumab and bevacizumab led to significant improvements in overall survival (OS), progression-free survival (PFS), and response rate compared with sorafenib in the phase III IMbrave150 trial. The etiology of background liver disease can differ between Eastern and Western populations, leading to a potentially different impact of systemic therapies; therefore the unequal representation must be considered in the IMbrave150 trial. To provide further data on the safety and effectiveness of atezolizumab and bevacizumab, the phase IIIb AMETHISTA (Atezolizumab plus bevacizumab in METastatic HCC Italian Safety TriAl) ran in a Western (Italian) population of patients with advanced HCC.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Ischemic damage to bile duct epithelium with development of cholestasis and retrograde biliary tract infection are considered as the main etiological factors. This work presents a clinical case of "Biliary-cast syndrome" in a patient with acute biliary pancreatitis and pulmonary embolism.
