Inflammatory Polyp in the Common Bile Duct with Pancreaticobiliary Maljunction
نویسندگان
چکیده
A 63-year-old woman was admitted because of epigastric pain and obstructive jaundice. Endoscopic retrograde cholangiopancreatography and intraductal ultrasonography revealed a 25-mm papillary nodule in the middle to inferior portion of the common bile duct (CBD). Pancreaticobiliary maljunction (PBM) was also identified. Contrast-enhanced computed tomography also showed an enhanced nodule in the CBD, and we suspected intraductal papillary neoplasm of the bile duct. We performed pylorus-preserving pancreatoduodenectomy. Postoperative pathological examination revealed an inflammatory polyp in the middle CBD. Inflammatory polyp in the bile duct is rare and there are no previous reports accompanied by PBM. PBM is a major risk factor for biliary tract cancer. Preoperative diagnosis of a benign disorder was difficult in this case.

Pitfalls of MRCP in the diagnosis of pancreaticobiliary maljunction.
CONTEXT Magnetic resonance cholangiopancreatography (MRCP) is useful for examining the pancreatic duct system in patients with acute pancreatitis instead of using endoscopic retrograde cholangiopancreatography (ERCP), as ERCP-induced pancreatitis represents a serious problem. However, we present here a case of idiopathic acute pancreatitis in which MRCP suggested pancreaticobiliary maljunction,...
متن کاملDue Significance Need be given to Pancreaticobiliary Maljunction in Pediatric Practice
Pancreaticobiliary maljunction (PBM) is a congenital anomaly defined as junction of the pancreatic and bile ducts located outside the duodenal wall beyond the influence of the sphincter of Oddi, usually forming a markedly long common channel. Other names are “anomalous arrangement of pancreaticobiliary ducts” or “anomalous union of biliopancreatic ducts” [1]. Average length of common channel is...
متن کاملPancreaticobiliary maljunction without bile duct dilatation in children: distinction from choledochal cyst.
OBJECTIVES Pancreaticobiliary maljunction without bile duct dilatation (nondilated type) is rare in children, and its definition remains unclear. There is controversy over treatment between pediatric and adult patients. We reevaluated our previous definition of the nondilated type in children (common bile duct diameter <or=6 mm on cholangiography). PATIENTS AND METHODS Of 150 children with pa...
متن کاملAnnular pancreas concurrent with pancreaticobiliary maljunction presented with symptoms until adult age: case report with comparative data on pediatric cases
BACKGROUND Annular pancreas (AP) concurrent with pancreaticobiliary maljunction (PBMJ), an unusual coexisted congenital anomaly, often presented symptoms and subjected surgical treatment at the early age of life. We reported the first adult case of concurrent AP with PBMJ presented with symptoms until his twenties, and performed a literature review to analyze the clinicopathological features of...
متن کاملAltered expression levels of occludin, claudin-1 and myosin light chain kinase in the common bile duct of pediatric patients with pancreaticobiliary maljunction
BACKGROUND In pancreaticobiliary maljunction (PBM), the sphincter of Oddi can not control bile and pancreatic juice flow, which may lead to two-way reflux of bile and pancreatic juice, thus causing chronic inflammation, thickening, fibrosis and metaplasia of the common bile duct wall. These pathophysiological changes have been linked to disruption of the epithelium barrier in the common bile du...
