BACKGROUND: When encountering solid pancreatic lesions, nonpancreatic primary metastases are rare and differentiating a metastasis from a primary neoplastic lesion is challenging. The clinical presentation and radiologic features can be similar and the possibility of a pancreatic metastasis should be considered when the patient refers to a history of a different primary cancer. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound-guided fine-needle aspiration has become the gold standard method for diagnosing pancreatic lesions...

INTRODUCTION: Primary neuroendocrine tumors (NET) of the extrahepatic biliary tree are a rare entity with less than 100 reported cases in the literature. PRESENTATION OF CASE: Here, we report a case of NET of the extrahepatic bile duct in a 64-year-old male patient presenting with painless jaundice, direct hyperbilirubinemia, and mildly elevated transaminases. Diagnostic workup with an ultrasound revealed dilation of the intrahepatic biliary ducts, without cholelithiasis or choledocholithiasis...

Endoscopic retrograde cholangiopancreatography (ERCP) has become the mainstay of therapy for pancreatobiliary diseases. While ERCP is safe and highly effective in the general population, the procedure remains challenging or impossible in patients with surgically altered anatomy (SAA). Endoscopic ultrasound (EUS) allows transmural access to the bile or pancreatic duct (PD) prior to ductal drainage using ERCP-based techniques. Also known as endosonography-guided cholangiopancreatography (ESCP), the procedure provides multiple advantages over overtube-assisted enteroscopy ERCP or percutaneous or surgical approaches...

Gallstones and their complications are one of most frequent gastroenterological diseases leading to hospital admission in Europe. Cholesterol stones are the most common; except of few patients there is a direct link to lifestyle. Obesity, diabetes and insufficient physical activity represent the major risk factors. Abdominal ultrasound is the gold standard for detection of gallstones. ERCP is indicated only in the therapeutic setting. In case of symptomatic gallbladder stones as well as bile duct stones, cholecystectomy is necessary...

Elevated liver enzymes are a frequent finding in both symptomatic and asymptomatic patients necessitating further evaluation to clarify the underlying disease. Three different patterns of increased liver enzymes can be defined to allow for a more precise and rational further diagnostic approach. A predominant increase in transaminase activities reflects a disturbance of hepatocellular integrity which can be found in patients with viral hepatitis, genetic liver diseases like Wilson`s disease or hemochromatosis, and drug-induced liver diseases...

The porta hepatis and hepatoduodenal ligament (HDL) are important anatomical pathways of extension of disease to and from the liver. The imaging of this area is difficult. The role of endoscopic ultrasound (EUS) as an imaging modality for hepatoduodenal ligament has not been established so far. All images in the present study have been generated from a detailed review of real time recordings using the curved linear scanning echoendoscope EG -3830 UT (Pentax Corporation, Tokyo, Japan), coupled with a Hitachi avius and Hitach 7500 processor (Hitachi Aloka Medical, Tokyo Japan)...

Background and Aim. A successful endoscopic ultrasound guided rendezvous (EUS-RV) biliary drainage is dependent on accurate puncture of the bile duct and precise guide wire manipulation across the ampulla of Vater. We aim to study the feasibility of using a flexible 19-gauge fine aspiration needle in the performance of EUS-RV biliary drainage. Method. This is a retrospective case series of EUS-RV biliary drainage procedures at a single center. Patients who failed ERCP during the same session for benign or malignant biliary obstruction underwent EUS-RV using a flexible, nitinol covered, 19-gauge needle for biliary access and guide wire manipulation...

Bo Sun, Bing Hu
Intraductal ultrasonography (IDUS) provides real-time, cross-sectional imaging of pancreatobiliary ducts and surrounding structures during endoscopic retrograde cholangiopancreatography using a high-frequency ultrasound (US) transducer. Hence, IDUS has been considered a sensitive tool in the evaluation of suspicious choledocholithiasis and neoplasms, to help distinguish between benign and malignant bile duct strictures or wall thickness, and to assess tumor extension and invasion depth. With the rapid development and enriched choices of sensitive diagnostic modalities include but are not limited to endoscopic US, peroral cholangioscopy, and confocal laser endomicroscopy, it is needed to systematically assess the role of IDUS in the investigation of pancreatobiliary diseases...

Cystic Dystrophy and Heterotopic Pancreas (CDHP) is a rare cause of chronic pancreatitis, duodenal obstruction and obstructive jaundice. The diagnosis is often delayed and requires multimodal imaging with Computed Tomography (CT), Magnetic Resonance Cholangio-Pancreatography (MRCP) and Endoscopic Ultrasound (EUS). The treatment is not standardized but Pancreatoduodenectomy (PD) provides long-term relief in some cases. The present case is about a 47-year-old male with history of alcohol abuse for 10 years who presented with a history of recurrent acute pancreatitis...

Common bile duct (CBD) stones are common in elderly adults, but the effect of aging on the presentation of CBD stones remains to be evaluated. Recent studies have demonstrated that the clinical presentation of CBD stones may vary with age. Younger adults may present with classical biliary colic symptoms, whereas elderly adults may have no unapparent clinical features. Younger adults with CBD stones were significantly more likely to have abnormal liver function tests than those without. The sensitivity and accuracy of transabdominal ultrasound scans in screening for CBD stones increases with age...

Portal biliopathy refers to cholangiographic abnormalities which occur in patients with portal cavernoma. These changes occur as a result of pressure on bile ducts from bridging tortuous paracholedochal, epicholedochal and cholecystic veins. Bile duct ischemia may occur due prolonged venous pressure effect or result from insufficient blood supply. In addition, encasement of ducts may occur due fibrotic cavernoma. Majority of patients are asymptomatic. Portal biliopathy is a progressive disease and patients who have long standing disease and more severe bile duct abnormalities present with recurrent episodes of biliary pain, cholangitis and cholestasis...

BACKGROUND: Periampullary cancer includes cancer of the head and neck of the pancreas, cancer of the distal end of the bile duct, cancer of the ampulla of Vater, and cancer of the second part of the duodenum. Surgical resection is the only established potentially curative treatment for pancreatic and periampullary cancer. A considerable proportion of patients undergo unnecessary laparotomy because of underestimation of the extent of the cancer on computed tomography (CT) scanning. Other imaging methods such as magnetic resonance imaging (MRI), positron emission tomography (PET), PET-CT, and endoscopic ultrasound (EUS) have been used to detect local invasion or distant metastases not visualised on CT scanning which could prevent unnecessary laparotomy...
