Intraductal papillary neoplasms of the bile duct (IPNBs) are recognized as a distinct type of biliary tumor. We herein discuss the possible mechanisms underlying the development of multiple tumors in patients with IPNBs through a case presentation and literature review. A 64-year-old woman initially underwent extended right hepatectomy for IPNB in the right hepatic duct. Although the surgical m...

Patient #1, a 45-year-old man who was being monitored because of chronic pancreatitis, had anicteric cholestasis and pain caused by double-duct stricture. Endoscopic retrograde cholangiopancreatography (ERCP) was undertaken using air, with the patient under general anesthesia with intubation (●" Fig.1). After short sphincterotomies had been done, self-expandingmetal stents were inserted (10mm d...

A 65-year-old woman underwent resection of a distal common bile duct carcinoma (Whipple's procedure). Twelve months later a single hepatic metastasis was detected and a chemoembolization was performed. Immediately after chemoembolization the patient developed a multimicrobial sepsis including Clostridium perfringens. CT scans depicted pathognomonic signs of gas-containing abscess in the necroti...

We report two cases of common bile duct stone formed around a fish bone which migrated from the intestinal tract, along with their characteristic imaging findings. Two patients who had no history of previous operation were admitted because of cholangitis. Percutaneous transhepatic biliary drainage (PTBD) was performed and the cholangiogram showed filling defects with an unusually elongated shap...

The ampulla of Vater represents the epithelial junction of the main pancreatic duct and the distal bile duct, surrounded by the pancreatic head and duodenum parenchyma. Ampullary carcinoma can arise either from the intestinal epithelium or the epithelium covering the pancreatobiliary ducts. Many tumors develop from pre-existing adenomas, others evolve from precursor intraepithelial neoplasia su...

Eimeria macusaniensis is an important coccidian intestinal parasite of New World camelids. It may be the same parasite as E. camelli, a similar-appearing intestinal coccidian of Old World camels, but this has not been proven. E. macusaniensis affects all ages of camelid, not just juveniles. Its contribution to illness may not be appreciated, since some camelids become sick up to two weeks befor...

This study describes for the first time the presence of H+-peptide cotransport in cells of the bile duct. Uptake of [glycine-1-14C]glycylsarcosine ([14C]Gly-Sar) in human extrahepatic cholangiocarcinoma SK-ChA-1 cells was stimulated sevenfold by an inwardly directed H+ gradient. Transport was mediated by a low-affinity system with a transport constant (Kt) value of 1.1 mM. Several dipeptides, c...

Chylothorax is the most common cause of pleural effusion in neonates. It is usually idiopathic. Neonatal chylothorax successfully respond to octreotide treatment and can reduce the duration of hospitalization. A number of therapeutic interventions have been used to reduce chyle production and promote resolution of a chylothorax. Initial management typically includes restriction or temporary ces...

BACKGROUND Percutaneous closure of patent ductus arteriosus (PDA) has become standard therapy. Experience with the Occlutech® Duct Occluder is limited. METHODS Data regarding ductal closure using Occlutech® Duct Occluder were reviewed and prospectively collected. Demographics, hemodynamic and angiographic characteristics, complications, and outcomes were documented. RESULTS From March 2013 ...
