Pancreato-Biliary Endoscopy Division and Endosonography Division, Pancreas Translational and Clinical Research Centre, San Raffaele Scientific Institute, Vita Salute San Raffaele University, Milan.

Purpose Of Review: Alcohol is a type I carcinogen and the WHO stated that it caused 5% of all deaths in 2016, of which 13% because of cancers. Among digestive tract cancers, this association is clear for esophageal, liver and colorectal cancer, and more debated for gastric and pancreatic cancer. The present review will revise recent evidence on epidemiologic association and mechanisms linking alcohol with the risk of esophageal, gastric, colorectal and pancreatic cancers. Read More

Yamanashi Prefectural Central Hospital, 1-1-1 Fujimi, Kofu-shi, Yamanashi, 400-8506, Japan.

Chronic hepatitis C virus (HCV) infection is common among patients with chronic kidney disease (CKD) and those on hemodialysis due to nosocomial infections and past blood transfusions. While a majority of HCV-infected patients with end-stage renal disease are asymptomatic, some may ultimately experience decompensated liver diseases and hepatocellular carcinoma. Administration of a combination of elbasvir/grazoprevir for 12 weeks leads to high sustained virologic response (SVR) rates in patients with HCV genotypes (GTs) 1a, 1b or 4 and stage 4 or 5 CKD.

Management of Acute Gallstone Cholangitis after Roux-en-Y Gastric Bypass with Laparoscopic Transgastric Endoscopic Retrograde Cholangiopancreatography.

Obes Surg 2018 Dec 11. Epub 2018 Dec 11.

Service de Chirurgie Générale et Endocrinienne, CHU Lille, Hôpital Huriez, Rue Michel Polonowski, 59000, Lille, France.

Background: The incidence of biliary lithiasis is increased after bariatric surgery due to rapid weight loss [1]. Trans-oral endoscopic management in cases of common bile duct gallstone complication is not possible in patients with Roux-en-Y gastric bypass (RYGB) due to the modified anatomy. Access to the biliary tree after RYGB with a classical direct surgical approach of common bile duct and choledocoscopy can be used, but may be complicated in situations of acute cholangitis because of the fragility of common duct, or in cases of previous cholecystectomy.

Safety and Efficacy of Low-Dose Single-Agent Capecitabine in Inoperable Gallbladder Cancer with Jaundice Post-Single-System Single-Catheter External Biliary Drainage: a Pilot Study from a Highly Endemic Area.

Indian J Surg Oncol 2018 Dec 31;9(4):530-537. Epub 2018 Jul 31.

1Department of General Surgery, King George's Medical University, Lucknow, UP India.

Gallbladder cancer (CaGB) in the subcontinent belongs to low socioeconomic status, and at the time of diagnosis, a large number is unresectable or inoperable so the palliative treatment remains the only option. In the present study, attempt was made to see the effect and safety profile of single-agent oral capecitabine in inoperable CaGB in presence of low levels of jaundice post-single-catheter transhepatic external biliary drainage. In  = 35 of inoperable jaundiced CaGB, post-biliary drainage capecitabine in low dose was started when their total bilirubin levels fell to 10 mg% or below. Read More

Heme oxygenase-1 induction by hemin prevents oxidative stress-induced acute cholestasis in the rat.

Clin Sci (Lond) 2018 Dec 11. Epub 2018 Dec 11.

Instituto de Fisiología Experimental (IFISE-CONICET) y Area Bioquímica Clínica, Facultad de Ciencias Bioquímicas y Farmacéuticas, UNR, Suipacha 570, Rosario, S2002LRL, Argentina

We previously demonstrated in and models that physiological concentrations of unconjugated bilirubin prevent oxidative stress (OS)-induced hepatocanalicular dysfunction and cholestasis. Here, we aimed to ascertain, in the whole rat, whether a similar cholestatic OS injury can be counteracted by heme oxygenase-1 (HO-1) induction that consequently elevates endogenous bilirubin (BR) levels. This was achieved through the administration of hemin, an inducer of HO-1, the rate-limiting step in BR generation. Read More

Portal vein embolization DOES not AFFECT the long-term survival and risk of cancer recurrence among colorectal liver metastases patients: A prospective cohort study.

Int J Surg 2018 Dec 8. Epub 2018 Dec 8.

Service de chirurgie hépatobiliaire et pancréatique et de transplantation, Département de chirurgie, Centre Hospitalier de l'Université de Montréal, Site St-Luc, Montréal, QC, Canada.

Background: Previous studies comparing the survival outcomes of liver resections with and without preoperative portal vein embolization (PVE) for colorectal liver metastases (CLM) have linked PVE to higher rate of tumor progression, lower overall survival (OS) and lower disease-free survival (DFS). The lack of adjusted models to compare these outcomes is a limitation of these studies since patients requiring PVE may differ significantly from the ones receiving upfront surgery.

Adjuvant Therapy for Biliary Tract Cancers.

J Oncol Pract 2018 Dec;14(12):701-708

South East Cancer Center, University Hospital Waterford, Waterford, Ireland; and Princess Margaret Cancer Centre, University of Toronto, Toronto, Ontario, Canada.

Biliary tract cancers, including gallbladder cancer, intrahepatic, perihilar, and distal cholangiocarcinomas, although anatomically contiguous, represent a heterogeneous group of cancers with extensive biologic and genetic diversity. With early disease, surgical resection is the preferred option for all subtypes; however, relapse rates remain high, and survival outcomes are poor. Data to guide the use of adjuvant therapy have been limited to retrospective series, population-based studies, and meta-analyses, all with their associated limitations. Read More

Mouse Model for Cholangiocarcinoma from Peribiliary Glands.

Methods Mol Biol 2019 ;1905:237-245

Department of Gastroenterology, The University of Tokyo, Tokyo, Japan.

A good mouse model is mandatory for elucidating carcinogenic mechanisms and identifying the cellular origin of cancer. Although the lack of an appropriate mouse model has hampered investigation of extrahepatic cholangiocarcinoma (ECC), we recently established a novel mouse model of biliary injury-related ECC by ductal cell-specific activation of Kras and deletion of transforming growth factor (TGF) β receptor type 2 and E-cadherin. Using this mouse model, we identified that peribiliary glands, which are considered a biliary epithelial stem cell niche, are potential cellular origins of ECC. Read More

Methods Mol Biol 2019 ;1905:187-198

Department of Pathology, School of Medicine, University of California, San Diego, CA, USA.

It has been demonstrated that the liver remarkably alter its tissue structures during regeneration, and various types of liver stem or progenitor cells locating in specific areas in the liver tissue contribute to regeneration. Therefore, it is important to analyze the dynamic rearrangement of the liver tissue structures in 3D for better understanding the process and mechanism of liver regeneration. Here we describe a macroscopic analysis method to visualize the whole 3D structure of the vasculatures and the biliary tree, which are dynamically remodeled during regeneration, and a microscopic analysis method to visualize detailed structures at the cellular level, which can compensate what cannot be detected in the macroscopic analysis.

Lineage tracing of liver cells is a powerful tool to understand liver embryonic development, healthy liver cell homeostasis, tissue repair, and regeneration. Lineage tracing of biliary epithelial cells (BECs) in the adult liver has been used to assess the contribution of the biliary epithelium to liver injury, regeneration, and disease. These studies have shown the contribution of BECs to the expansion of ductular reaction (DR) and liver progenitor cells (LPCs) and eventually the generation of new hepatocytes. Read More
