AIM To determine the sensitivity and specificity of endoscopic ultrasonography (EUS) in patients with inconclusive magnetic resonance imaging/magnetic resonance cholangiopancreatography (MRI/MRCP) in pancreatobiliary abnormalities. METHODS During 10 months, patients with pancreatobiliary diseases referred to endoscopic retrograde cholangiopancreatography (ERCP) because of inconclusive MRI/MRC...

We report a case of papillary carcinoma of the duodenum combined with right renal carcinoma. A 58-year-old man underwent a physical examination that revealed intrahepatic and extrahepatic bile duct dilatation on B ultrasound. Intrahepatic bile duct dilatation could be seen on magnetic resonance imaging (MRI), but the head of the pancreas and distal bile duct showed no tumor signals, which led t...

annular pancreas (ap) is a rare congenital abnormality in which pancreatic tissue completely surround the duodenum. presentation of ap in adulthood is very rare and obstructive jaundice is one of the uncommon manifestations of ap in adults. herein; we reported a 47 years old woman who presented with icterus, midcommon bile duct stricture and annular pancreas. she was diagnosed as pancreas cance...

Previous work demonstrated that serum metabolomics can distinguish pancreatic cancer from benign disease. However, in the clinic, non-pancreatic periampullary cancers are difficult to distinguish from pancreatic cancer. Therefore, to test the clinical utility of this technology, we determined whether any pancreatic and periampullary adenocarcinoma could be distinguished from benign masses and b...

Periampullary duodenal diverticula are not uncommon and are usually asymptomatic although complications may occasionally occur. Here, we report the case of a 72-year-old woman who presented with painless obstructive jaundice. Laboratory tests showed abnormally elevated serum concentrations of total and direct bilirubin, of alkaline phosphatase, of γ-glutamyl transpeptidase, and of aspartate and...

BACKGROUND In patients with non-resectable peri-ampullary cancer, optimization of quality of life is an important goal. Although endoscopic palliation is widely used, the proponents of laparoscopic biliary bypass claim that this procedure alters management towards surgery. However, the evidence base for selection of laparoscopic bypass is limited and the aim of this report is to scrutinize the ...
