BACKGROUND:  Tissue sampling for biliary stricture is important for differential diagnosis and further treatment. The aim of this study was to assess a novel dilation catheter-guided mini-forceps biopsy (DCMB) method in the diagnosis of malignant biliary strictures. METHODS:  42 patients with malignant biliary stricture who underwent both brush cytology and DCMB during endoscopic retrograde cholangiopancreatography between October 2014 and November 2015 were retrospectively included...

Background and study aims:  Biliary strictures are frequently a challenging clinical scenario and the anatomopathological diagnosis is essential in the therapeutic management, whether for curative or palliative purposes. The acquisition of specimens is necessary since many benign diseases mimic biliopancreatic neoplasms. Endscopic retrograde cholangiopancreatography (ERCP) is the traditionally used method despite the low sensitivity of biliary brush cytology and forceps biopsy. On the other hand, several studies reported good accuracy rates using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA)...

Endoscopic transpapillary brush cytology and forceps biopsy during endoscopic retrograde cholangiopancreatology are generally used to obtain pathological evidence of biliary strictures. Recently, the new endoscopic scraper Trefle® has been reported and demonstrated high cancer detectability in malignant biliary strictures. This device is used to scrape the stricture over the guidewire, and, in the original method, the tissue and/or cell samples obtained are subjected to histological and/or cytological analysis separately...

BACKGROUND AND AIMS: Our goal was to compare the diagnostic accuracy of FISH in the detection of malignancy compared with other standard diagnostic modalities, including brush cytology and biopsy specimens over a 10-year period of prospective data collection. METHODS: We conducted a review of all consecutive biliary strictures evaluated between 2006 and 2016. Patients with a final pathologic diagnosis or conclusive follow-up were included. We evaluated the performance of FISH polysomy (CEP 3, 7, and 17) and 9p21 deletion as well as cholangioscopic biopsy (CBx) and EUS-FNA...

BACKGROUND/AIMS: It is sometimes difficult to distinguish between malignant and benign biliary strictures using imaging studies alone, and pathological diagnosis is necessary. The aim of this study was to determine the usefulness of endoscopic transpapillary tissue sampling and factors predictive of diagnostic accuracy. METHODS: From April 2008 to December 2014, 136 patients underwent endoscopic transpapillary tissue sampling for malignant biliary strictures. The cytological and histological findings were reported as negative, suspicious, or positive...

OBJECTIVES: To evaluate percutaneous brush cytology, forceps biopsy and a tandem procedure consisting of both, in the diagnosis of malignant biliary obstruction. METHODS: A retrospective review of consecutive patients who underwent biliary brush cytology and/or forceps biopsy between 01/2010 and 09/2014 was performed. The cytology and pathology results were compared to the composite outcome (including radiological, pathological and clinical data). Cost for tandem procedure compared to brush cytology and forceps biopsy alone was calculated...

We report a case of a 70-year-old man with acute acalculous cholecystitis caused by Giardia lamblia. Contrast-enhanced computed tomography (CT) showed distention of the gallbladder due to a pericholecystic abscess without gallstones. Magnetic resonance cholangiopancreatography and drip infusion cholecystocholangiography-CT demonstrated a stricture of the hilar bile duct and cystic duct obstruction. We conducted transpapillary bile duct brush cytology and a biopsy of the hilar bile duct stricture; numerous active trophozoites of Giardia lamblia were observed without malignant findings...

Bile duct brush cytology, intraductal biopsy and EUS-FNA are all used to characterize biliary strictures, with suboptimal sensitivity. Surgical resection without confirmed malignancy is undesirable. Cholangioscopy with targeted biopsies appears to increase the diagnostic yield in indeterminate biliary strictures, but it is still considered optional.

Background and Aims: There are no systematic reviews comparing the use of endoscopic retrograde cholangiopancreatography (ERCP)-based brush cytology and forceps biopsy and endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) for the diagnosis of malignant biliary stricture; so in this revision, we will compare ERCP against EUS-FNA for tissue diagnosis of malignant biliary stricture. Design: A systematic review was conducted of comparative studies (prospective or retrospective) analyzing EUS and ERCP for tissue diagnosis of malignant biliary stricture...

Cholangiocellular carcinoma (CCA) is the second most frequent primary liver carcinoma and is an aggressive tumor, which is mostly diagnosed in advanced stages. The overall survival is poor. Histpathological analysis of tumor biopsies or cytological analysis of biliary brushings can be used to confirm the diagnosis. A differentiation is made between distal, perihilar and intrahepatic CCA. The anatomical position determines the diagnostic and therapeutic strategy. Before diagnostic or therapeutic measures are undertaken it is essential to resolve biliary obstruction via endoscopic stenting or percutaneous biliary drainage...

BACKGROUND: The accuracy of current endoscopic modalities for diagnosing cholangiocarcinoma in primary sclerosing cholangitis (PSC) is suboptimal. AIM: To evaluate the comparative effectiveness of endoscopic retrograde cholangiopancreatography (ERCP)-based modalities, independently or in combination, for the diagnosis of cholangiocarcinoma in patients with PSC-induced biliary strictures. METHODS: Searches of PubMed, EMBASE, Web of Science and the Cochrane Library databases were performed through December 2015...

BACKGROUND AND AIMS: Cholangiocarcinoma (CCA) is a leading cause of morbidity and mortality in patients with primary sclerosing cholangitis (PSC). Although several ERCP-based diagnostic modalities are available for diagnosing CCA, it is unclear whether one modality is more cost-effective than the others. The primary aim of this study was to compare the cost-effectiveness of ERCP-based techniques for diagnosing CCA in patients with PSC-induced biliary strictures. METHODS: We performed a cost utility analysis to assess the net monetary benefit for accurately diagnosing CCA using 5 different diagnostic strategies: (1) ERCP with bile duct brushing for cytology, (2) ERCP with brushings for cytology and fluorescence in situ hybridization (FISH)-trisomy, (3) ERCP with brushings for cytology and FISH-polysomy, (4) ERCP with intraductal biopsy sampling, and (5) single-operator cholangioscopy (SOC) with targeted biopsy sampling...

Biliary epithelial cells preferentially respond to various insults under chronic pathological conditions leading to reactively atypical changes, hyperplasia, or the development of biliary neoplasms (such as biliary intraepithelial neoplasia, intraductal papillary neoplasm of the bile duct, and cholangiocarcinoma). Moreover, benign biliary strictures can be caused by a variety of disorders (such as IgG4-related sclerosing cholangitis, eosinophilic cholangitis, and follicular cholangitis) and often mimic malignancies, despite their benign nature...

Endoscopic evaluation of indeterminate biliary strictures (IDBSs) has evolved considerably since the development of flexible fiberoptic endoscopes over 50 years ago. Endoscopic retrograde cholangiography pancreatography (ERCP) was introduced nearly a decade later and has since become the mainstay of therapy for relieving obstruction of the biliary tract. However, longstanding methods of ERCP-guided tissue acquisition (i.e., biliary brushings for cytology and intraductal forceps biopsy for histology) have demonstrated disappointing performance characteristics in distinguishing malignant from benign etiologies of IDBSs...
