miR-122-5p Inhibits the Proliferation, Invasion and Growth of Bile Duct Carcinoma Cells by Targeting ALDOA.

Bile duct cancer, although not among the most common tumors, still accounts for more and more worldwide deaths each year. By attempting to verify an overexpression of ALDOA in cholangiocarcinoma tissues and cells and explore the underlying molecular mechanism regulated by miR-122-5p, this study was designed to provide a potential molecular target in bile duct cancer treatment.

Use of a Lithotripter to Salvage a Bile duct stone and Kinking Retrieval Basket In the Distal Common Bile Duct.

A 65-year-old man was transferred from a secondary hospital after a bile duct stone and a retrieval basket became impacted in the common bile duct (CBD) during an endoscopic retrograde cholangiopancreatography (ERCP). Prior to transfer, lithotripsy after exchanging the basket sheath for a metal sheath was tried but failed because of the fracture of a wire near the patient's mouth. After transfer to our facility, we attempted an ERCP prior to considering surgery. This article is protected by copyright. All r...

Cytologic diagnosis of adenocarcinoma on bile duct brushings in the presence of stent associated changes: A retrospective analysis.

Bile duct brushing (BDB) cytology, for the characterization of bile duct strictures, can be challenging to interpret when associated with a stent. Our study aims to identify the cytologic criteria for the diagnosis of adenocarcinoma in BDBs in the presence of a stent.

Ex vivo magnifying endoscopic observation of bile duct mucosa using narrow band imaging.

Detailed endoscopic findings of the bile duct mucosa have not been fully established. This fundamental ex vivo study assesses the relationship between magnified endoscopic findings and pathological findings of the bile duct mucosa.

A case of a right accessory hepatic duct diagnosed during a Whipple procedure.

Although anatomic variations of the bile tract are relatively common and can be present in about 28% of patients, existence of an accessory right hepatic duct that confluence on the common bile duct is quite rare.

Laparoscopic cholecystectomy with aberrant bile duct detected by intraoperative fluorescent cholangiography concomitant with angiography: A case report.

Laparoscopic cholecystectomy is the standard surgical treatment for patients with benign gallbladder disease. However, bile duct injury continues to be reported as a surgical complication. Intraoperative cholangiography is recommended to reduce the risk of bile duct injury during laparoscopic cholecystectomy. Intraoperative cholangiography using indocyanine green, which is excreted into bile and shows fluorescence under infrared light, has recently been reported as useful in preventing bile duct injury duri...

FDG PET/CT Imaging of Hepatocellular Carcinoma With Bile Duct Tumor Thrombus.

Hepatocellular carcinoma rarely involves the major bile duct. Here, we reported a 46-year-old man with liver cancer who underwent FDG PET/CT for staging. The images showed abnormal FDG uptake in the left lobe and hilum of the liver, which was confirmed as hepatocellular carcinoma and hepatic portal bile duct tumor thrombus, respectively, by the pathology.

Intraductal papillary neoplasm of the bile duct with rapidly progressive multicentric recurrence: A case report.

Knowledge on the pattern of recurrence and prognosis of intraductal papillary neoplasms of the bile duct (IPNB) is limited. Few studies have reported IPNB recurrence in the remnant intrahepatic bile duct, which is indicative of the true multicentricity of IPNB. Herein, we report a case of IPNB with rapidly progressive recurrence in the remnant intrahepatic bile duct and review the literature for discussing the prognosis of IPNB with multicentricity.

Reliability and accuracy of a novel classification system using peroral cholangioscopy for the diagnosis of bile duct lesions.

 The aim of this study was to propose a novel, comprehensive, macroscopic classification for bile duct lesions.

Bile acids drive chemotaxis of Clonorchis sinensis juveniles to the bile duct.

Clonorchiasis is a neglected tropical disease caused by Chinese liver fluke, Clonorchis sinensis infection. C. sinensis is a biological carcinogen causing cholangiocarcinoma in humans. In the mammalian host, C. sinensis newly excysted juveniles (CsNEJs) migrate from the duodenum into the bile duct. Bile drives the chemotactic behavior of CsNEJs. Little is known about which components of bile induce the chemotaxis. We designed a chemotaxis assay panel and measured the chemotactic behavior of CsNEJs in respon...

A case of obstructive jaundice due to early carcinoma of the cystic duct protruding into the common bile duct.

Cystic duct carcinoma is a rare disease, and only 33 cases reported worldwide have completely fulfilled the criteria first established by Farrar in 1951. Here we describe an extremely rare case of early cystic duct carcinoma that fulfilled the Farrar criteria, the papillary tumour protruding into the common bile duct, leading to obstructive jaundice.

Live Donor Liver Transplantation Using Selected Grafts with Two Bile Ducts compared to One Bile Duct Does Not Impact on Patient Outcome.

We read with great interest the article from the Toronto group showing similar results with grafts with one or more bile ducts in living donor liver transplantation (LDLT). (1) However, one should take this message cautiously as intuitively a graft with one duct is preferred by most surgeons. Some previous studies have demonstrated that multiple bile ducts were significant independent risk factor for development of biliary complications with no difference in patient survival when compared with single duct i...

Surgical Outcomes of Hepatocellular Carcinoma With Bile Duct Tumor Thrombus: A Korea-Japan Multicenter Study.

To identify optimal surgical methods and the risk factors for long-term survival in patients with hepatocellular carcinoma accompanied by macroscopic bile duct tumor thrombus (BDTT).

Comparison of endoscopic papillary large balloon dilation with or without endoscopic sphincterotomy for the treatment of large bile duct stones.

Endoscopic papillary large balloon dilation (EPLBD) without prior endoscopic sphincterotomy (EST) produces excellent outcomes for the treatment of large common bile duct (CBD) stones. However, it remains unclear how the outcomes of EPLBD alone compare with those of EPLBD with EST. In this study, we assessed the safety and therapeutic outcomes of EPLBD with vs. without EST for the removal of large bile duct stones.

DLEC1 methylation is associated with a better clinical outcome in patients with intrahepatic cholangiocarcinoma of the small duct subtype.

Intrahepatic cholangiocarcinoma is a complex disease with three different histologic subtypes, the large duct, small duct, and bile ductular types. In the present study, we elucidated whether the three histological subtypes have differences in their methylation profiles and developed a DNA methylation marker that might help identify a subset of ICC with a different prognosis. We screened 113 promoter CpG island loci against 10 cases of intrahepatic cholangiocarcinoma and normal cystic ducts using the MethyL...

Predictors of Failed Transcystic Laparoscopic Common Bile Duct Exploration: Analysis of Multicenter Integrated Health System Database.

The aim of this study is to report our experience with laparoscopic common bile duct exploration (LCBDE) and validate the experts' opinion about anatomical predictors of failed transcystic LCBDE (TLCBDE) approach.

The reasonable drainage option after laparoscopic common bile duct exploration for the treatment of choledocholithiasis.

To obtain a reasonable drainage after laparoscopic common bile duct exploration (LCBDE) for the treatment of choledocholithiasis.

Bile micro-infarcts in cholestasis are initiated by rupture of the apical hepatocyte membrane and cause shunting of bile to sinusoidal blood.

Bile duct ligation (BDL) is an experimental procedure that mimics obstructive cholestatic disease. One of the early consequences of BDL in rodents are so-called 'bile infarcts' that correspond to Charcot-Gombault necrosis in human cholestasis. The mechanisms causing bile infarcts and their pathophysiological relevance are unclear. Therefore, intravital two-photon-based imaging of bile duct-ligated mice was performed with fluorescent bile salts (BS) and non-BS organic anion analogues. Key findings were follo...

Safe Laparoscopic Cholecystectomy: A Systematic Review of Bile Duct Injury Prevention.

Since the introduction of laparoscopic cholecystectomy (LC), a substantial increase in bile duct injury (BDI) incidence was noted. Multiple methods to prevent this complication have been developed and investigated. The most suitable method however is subject to debate. In this systematic review, the different modalities to aid in the safe performance of LC and prevent BDI are delineated.

Management of iatrogenic bile duct injuries: Multiple logistic regression analysis of predictive factors affecting morbidity and mortality.

Iatrogenic bile duct injuries remain a challenge for the surgeons to overcome. The predictive factors affecting morbidity and mortality are important for determining the best management modality.

A case report: Feasibility of a near infrared ray vision system (Photo dynamic eye®) for the postoperative ischemic complication of gallbladder carcinoma.

Radical resection with or without preserving extra-hepatic bile duct has shown similar prognoses for gallbladder carcinoma (GB ca), although aggressive resection is essential. In preserving bile duct, ischemic complications are serious, life-threatening serious problems. Correct evaluation of the blood flow to the biliary tract is crucial.

Colon liver metastasis complicated with tumor thrombus in the bile duct: A case report.

Hepatectomy including conversion therapy is recommended for colorectal liver metastasis (CRLM). CRLM complicated with bile duct tumor thrombus (BDTT) is rare, even though there are more opportunities to perform hepatectomy for CRLM in recent years.

Rare case of idiopathic sclerosing cholangitis, which was difficult to distinguish from cholangiocarcinoma: A case report.

It is often difficult to correctly diagnose patients who present with dilation of the bile duct. Cholangiocarcinoma, primary sclerosing cholangitis (PSC) and immunoglobulin (Ig)G4-related sclerosing cholangitis must be considered as potential diagnoses for these cases. The current study presents a 73-year-old female patient who presented with a high fever and abdominal pain. Contrast-enhanced computed tomography and magnetic resonance cholangiopancreatography revealed stenosis and dilation of the intrahepat...

Reference limits for hepatic bile duct-to-arteriole and bile duct-to-portal tract ratios in healthy cats.

OBJECTIVE To establish reference limits for hepatic bile duct-to-arteriole ratio (BD:A) and bile duct-to-portal tract ratio (BD:PT) in healthy cats and assess whether these parameters could be used to support a diagnosis of biliary ductopenia in cats. SAMPLE Hepatic biopsy samples from healthy cats (n = 20) and cats with ductopenia (2). PROCEDURES Hepatic biopsy samples from healthy cats were used to count the number of bile ducts and hepatic arterioles in 20 portal tracts for each cat. Mean BD:A and mean B...

Spindle and giant cell type undifferentiated carcinoma of the distal bile duct: a case report.

Undifferentiated carcinoma of the biliary tract is rare and more frequently occurs in the gall bladder than in the extrahepatic bile ducts. We report on an extremely rare case of a spindle and giant cell type undifferentiated carcinoma of the distal bile duct. In the presented tumor, atypical glands and single-cell clusters arising from the bile duct epithelium gradually transitioned into a predominantly sarcomatoid architecture, which constituted more than 98 % of the whole tumor volume. Focally, osteocl...
