abstract autoimmune pancreatitis (aip) is a rare disorder that may be present as common bile duct stricture. the patient was a seventy-year-old man with presentations as recurrent abdominal pain and jaundice, elevated billirobin (bil) and elevated alkaline phosphatase (alkp) in association with the presence of hetrogenesity of the pancreatic head and dilated intra and extra hepatic bile ducts i...

agnostic workup because of elevated serum liver enzyme levels (γ-glutamyltransferase 53.94 μkat/L, reference range 0.00–0.63). A transabdominal ultrasound revealed dilated extrahepatic bile ducts, and on endoscopic ultrasound (EUS) the common bile duct (CBD) was dilated with hyperechoic fociwith no acoustic shadowing within, and a 20-mm hyperechoic frond-like mass was noted within the infundibu...

Fibrosis, bile duct proliferation and mast cell hyperplasia characterize extrahepatic cholestasis. We studied these liver alterations in a new microsurgical model of extrahepatic cholestasis in the rat. Male Wistar rats: Sham-operated (n=9) and Microsurgical Cholestasis (n=10). After 4 weeks, a liver morphometric study was carried out using an image analysis system to assess bile proliferation ...

BACKGROUND After hepatectomy, bile leaks remain a major cause of morbidity, cost, and disability. This study was designed to determine if a novel intraoperative air leak test (ALT) would reduce the incidence of post-hepatectomy biliary complications. STUDY DESIGN Rates of postoperative biliary complications were compared among 103 patients who underwent ALT and 120 matched patients operated o...

Bile ducts are hepatic tubular structures that are lined by cholangiocytes, a type of liver epithelial cell. Cholangiocytes first form a single layer of cells, termed the ductal plate, surrounding the portal vein, which eventually remodels into the branching tubular network of bile ducts. The process of bile duct morphogenesis is not yet clear: a conventional model where cholangiocytes prolifer...

OBJECTIVE The purpose of this study was to evaluate the MR spectrum and MR cholangiographic imaging findings of clonorchiasis. MATERIALS AND METHODS We reviewed 26 patients with confirmed clonorchiasis by either stool tests (n=24) or surgery (n=2). MR imaging was performed on a 1.5 T system (GE Medical Systems, Milwaukee, WI) with a torso coil. Axial T1- and T2-weighted, gadolinium-enhanced d...

INTRODUCTION We report an unusual presentation of a small hepatic cyst causing cholangitis. CASE PRESENTATION A 70-year-old Asian man was hospitalized for aggravated chronic pain in the right upper portion of his abdomen. Fever developed after admission. Laboratory tests revealed elevated hepatobiliary enzymes, inflammatory markers and carbohydrate antigen 19-9 without hyperbilirubinemia. Ult...

Cholangiocarcinoma (CC) of the biliary tract occasionally presents a predominant intraductal papillary growth in the bile ducts, called as biliary tract carcinoma (BTC) of papillary growth (PG) and intrahepatic CC (ICC) of intraductal growth (IG) type. Recently, intraductal papillary neoplasm of bile duct (IPNB) has been proposed as a pre-invasive biliary neoplasm. This study was performed to c...

Most biliary tract neoplasms are malignant and have been traditionally divided into cancers of the gallbladder, the extrahepatic bile ducts, and ampulla of Vater. Although infrequent, bile duct carcinomas and cancer of the gallbladder are not rare. In the United States, an estimated 6,000 to 7,000 new cases of carcinoma of the gallbladder and 3,000 to 4,000 new cases of carcinoma of the bile du...
