Cholangiocarcinoma (CC) is a rare malignant tumour arising from cholangiocytes, and its prognosis is usually unfavourable, mostly as a result of late diagnosis of the tumour. The current incidence of cholangiocarcinoma in the Czech Republic is 1.4/100,000 inhabitants per year; in less than 30 % of patients with CC, one of the known risk factors can be identified, most frequently, primary sclerosing cholangitis. Only patients with early diagnosed and surgically amenable cholangiocarcinoma are likely to have a longer survival time; in their case, survival for more than five years has been achieved in 20 % to 40 %...

BACKGROUND/AIMS: It is difficult to diagnose cholangiocarcinoma in the early stages because most patients present with jaundice, which is generally thought to be the most important symptom at diagnosis. Despite improvements to surgical instruments and techniques, these rates are not quite satisfactory. Intraductal ultrasound (IDUS) is easy to handle due to the wire-guided, thin-caliber, and high-frequency probe. The purpose of the present study was to assess the efficacy of IDUS as a diagnostic tool for patients with early distal cholangiocarcinoma...

BACKGROUND/AIMS: Primary sclerosing cholangitis (PSC) is often complicated by cholangiocarcinoma (CCA); thus, early detection of CCA is an important way to improve PSC prognosis. METHODOLOGY: In a retrospective study, 23 cases of PSC were included. Seven cases were complicated by CCA (CCA group) and 16 cases were not (control group). Blood examinations, bile duct imagings from direct cholangiography, intraductal ultrasonography (IDUS) findings and pathological diagnosis results (bile juice cytology, brush cytology, and forceps biopsy) were referenced...

Intraductal ultrasonography (IDUS) is one of the most useful diagnostic tools for various extrahepatic biliary diseases. However, conventional IDUS has some limitations in providing accurate cross-sectional imaging of the bile duct in patients with extensive pneumobilia. Using a balloon-sheathed catheter, the US system (balloon-sheathed IDUS) can overcome these limitations. Sixteen patients underwent balloon-sheathed IDUS during endoscopic retrograde cholangiography. The balloon-sheathed IDUS was inserted via a transpapillary route when visualization of the bile duct with conventional IDUS was distorted by extensive pneumobilia...

Background and Aim. Distal cholangiocarcinoma associated with choledocholithiasis has not been reported, and the causal relationship remains to be established. We evaluated diagnosis of distal cholangiocarcinoma diagnosed after the removal of choledocholithiasis. Patients and Methods. We assigned 9 cases of cholangiocarcinoma with choledocholithiasis to Group A. As a control group, 37 patients with cholangiocarcinoma without choledocholithiasis were assigned to Group B. Results. Abdominal pain at admission is the only significant difference between Group A and Group B (P = 0...

The technique of intraductal ultrasonography (IDUS) of the bile duct with a thin-caliber probe and a ropeway system has provided excellent images of the bile duct and periductal structures and is an easy transpapillary approach. In addition, once the guide wire is inserted into the bile duct, IDUS and transpapillary biopsy after endoscopic retrograde cholangiopancreatography can be performed in a single session. Here, we review the usefulness of IDUS in the diagnosis of cholangiocarcinoma and IgG4-related sclerosing cholangitis...

The accurate diagnosis of extrahepatic bile duct carcinoma is difficult, even now. When ultrasonography (US) shows dilatation of the bile duct, magnetic resonance cholangiopancreatography followed by endoscopic US (EUS) is the next step. When US or EUS shows localized bile duct wall thickening, endoscopic retrograde cholangiopancreatography should be conducted with intraductal US (IDUS) and forceps biopsy. Fluorescence in situ hybridization increases the sensitivity of brush cytology with similar specificity...

BACKGROUND/PURPOSE: IgG4-related sclerosing cholangitis (IgG4-SC) is one of several diseases associated with autoimmune pancreatitis (AIP). However, diffuse cholangraphic abnormalities seen in association with AIP may resemble those seen in primary sclerosing cholangitis (PSC), and the presence of segmental stenosis suggests cholangiocarcinoma. IgG4-SC responds well to steroid therapy, whereas in contrast, liver transplantation is the only effective therapy for PSC, and surgical intervention is also needed for cholangiocarcinoma...

BACKGROUND AND AIM: In hilar cholangiocarcinoma, an accurate assessment of preoperative resectability is important to optimize surgical resection. We investigated the accuracy of the combination of intraductal ultrasonography (IDUS) and percutaneous transhepatic cholangioscopy (PTCS) for evaluating longitudinal extent in hilar cholangiocarcinoma. METHODS: Patients diagnosed with hilar cholangiocarcinoma underwent multidetector computed tomography (MDCT) and magnetic resonance cholangiography (MRC) for tumor staging and Bismuth type...

PURPOSE: IgG4-related sclerosing cholangitis (IgG4-SC) is one of the diseases associated with autoimmune pancreatitis. Several cases of IgG4-SC showed no pancreas abnormalities and it was difficult to distinguish cholangiocarcinoma. We aimed to clarify the findings of transpapillary intraductal ultrasonography (IDUS) and bile duct biopsy in the patients with IgG4-SC. METHODS: We retrospectively evaluated the findings of transpapillary IDUS and biopsy in 23 consecutive patients with IgG4-SC at Nagoya City University Hospital between 2004 and 2008...

OBJECTIVE: Primary sclerosing cholangitis (PSC) is associated with the development of cholangiocarcinoma (CC) in approximately 9% of patients. Neither cholangiography nor endoscopic tissue sampling can reliably distinguish between CC and benign dominant bile duct stenosis. The aim of the present study was to assess the value of intraductal ultrasonography (IDUS) in distinguishing between benign and malignant dominant stenoses in PSC patients. MATERIAL AND METHODS: Forty PSC patients with dominant bile duct stenoses were studied prospectively...

BACKGROUND AND STUDY AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is the diagnostic procedure of choice in patients with biliary strictures and no culprit mass lesion on abdominal imaging, but it is limited in its diagnostic accuracy. The aim of this prospective study was to determine the value of intraductal ultrasound (IDUS) in distinguishing between benign and malignant biliary strictures in this clinical setting. PATIENTS AND METHODS: Sixty-one patients with painless jaundice and no mass lesion on abdominal computed tomography, who were found to have a biliary stricture at ERCP, underwent IDUS with a high-frequency (20-MHz) wire-guided probe...

Byung Moo Yoo
The prognosis of hilar cholangiocarcinoma is very poor due to its location and complicated anatomical characteristics. The bile duct cancer arising in the hilum easily invades the vascular structures and spreads along the bile duct. Complete curation could only be expected when curative resection of the hilar cholangiocarcinoma had been achieved. For the operability to be decided, the evaluation of longitudinal and vertical tumor extensions are important. Preoperative endoscopic staging work-up could be performed using endoscopic retrograde cholangiography (ERC), choledochoscopy, endoscopic ultrasonography (EUS) and intraductal ultrasonography (IDUS)...

The instruments and processing systems of intraductal ultrasonography (IDUS) and 3D-IDUS are developing. IDUS is a reliable method for the evaluation of cholangiocarcinoma, and accurate staging is the most significant role of IDUS. DPR images produced by 3D-IDUS are useful to assess the tumor extension and the relationship with surrounding organs. 3D-IDUS is more useful for the precise diagnosis of cancer extension in cholangiocarcinoma, especially in invasion into the portal vein and pancreas, than CT scan and angiography...

OBJECTIVE: This study assesses the value of intraductal ultrasound (IDUS) when the findings of endoscopic retrograde cholangio-pancreatography (ERCP) are unclear. PATIENTS AND METHODS: IDUS was performed over a two-year period in cases of bile duct or pancreatic duct stenosis of unknown origin found during ERCP or if cholelithiasis was suspected but ERC was seemingly normal. Duct stenoses were classified,before and after IDUS, as benign or malignant ductal or malignant extraductal, the findings then being checked by clinical follow-up,histology or, if bile duct stones had been suspected, by instrumental bile duct exploration...

BACKGROUND: We wanted to distinguish wall thickening caused by cancer extension from that caused by inflammation after placing a biliary catheter on intraductal ultrasonography (IDUS). METHODS: We studied 51 patients with biliary tract malignancies who had undergone placement of biliary drainage catheters before IDUS. IDUS was performed from a transhepatic (n = 34) or transpapillary (n = 17) route with a thin-caliber ultrasonic probe (2.0 mm in diameter, 20-MHz frequency)...

The development of endoscopic biliary stenting (EBS), using the Wallstent, to treat patients with obstructive jaundice secondary to unresectable tumors of the pancreas or biliary ducts has led to improved quality of life in these patients. We followed six patients with intraductal ultrasonography (IDUS) after insertion of a Wallstent. In two patients, endoscopic ultrasonography (EUS) was also performed, and in three patients IDUS was repeated every few months. IDUS allowed ingrowth of the tumor or formation of debris in the stent to be observed clearly and easily...
