A 55-day-old boy was transferred to our unit with intestinal obstruction and obstructive jaundice after two neonatal operations for duodenal atresia and intestinal malrotation. Abdominal ultrasound showed dilated intrahepatic and extrahepatic ducts with cut-off at the distal common bile duct (CBD).
Intraductal papillary mucinous neoplasms (IPMN) are characterized by the growth of epithelial components with mucin production in the main pancreatic duct, or a large branch. We report a case of intraductal papillary mucinous carcinoma (IPMC) of the pancreatic head, complicated by pancreaticobiliary
BACKGROUND
The pathogenesis of biliary atresia (BA) is still unknown. There are several reports on the etiology of BA, including pancreaticobiliary maljunction (PBM). We experienced a case of Kasai type IIIa BA with PBM, in which we found elevation of pancreatic enzymes in the gallbladder. We
It is known that the etiology of congenital biliary dilatation (CBD) is closely associated with pancreaticobiliary maljunction (PBMJ). Treatment of CBD today is primary excision of the cyst followed by hepaticoenterostomy. However, PBMJ without dilatation of the biliary tract has recently been
Pancreaticobiliary maljunction (PBM) usually is associated with choledochal cyst. PBM without dilatation of the common bile duct is rare in infants and children. This rare type of the anomaly may lead to the development of malignancy of the bile duct in later life. The authors report the clinical
OBJECTIVE
To clarify the strategy for early diagnosis of pancreaticobiliary maljunction (PBM) without biliary dilatation and to pathologically examine gallbladder before cancer develops.
METHODS
The anatomy of the union of the pancreatic and bile ducts was assessed by using endoscopic retrograde
Pancreaticobiliary maljunction (PBM) is associated with the occurrence of biliary cancer due to pancreatobiliary reflux. We present a case of simultaneous double cancer of the gallbladder and bile duct. A 77-year-old woman who had jaundice, intra- and extra-hepatic biliary ductal dilatation and a
Pancreaticobiliary maljunction (PBM) is associated with the occurrence of biliary cancer due to pancreatobiliary reflux. From the perspective of carcinogenesis, the treatment for PBM is controversial. We herein report a case of hilar cholangiocarcinoma 20 years after the occurrence of gallbladder
BACKGROUND
Pancreaticobiliary maljunction (PBM) is frequently associated with congenital choledochal cyst (CCBD), but differs in embryonic cause and clinical features. It is thought to develop as a misarrangement of the embryonic connections in the pancreaticobiliary ductal system, with the terminal
The purpose of this review is to evaluate our current knowledge of the embryologic etiology of pancreaticobiliary maljunction (PBM), its diagnosis, clinical aspects, and treatment, and to clarify the mechanisms of PBM involvement in carcinogenesis. Although the embryologic etiology of PBM still
The concept of congenital biliary dilatation (CBD) was established by Alonso-Lej whose classification has been widely accepted and become a standard. Todani, Komi and several investigators then added additional subclassifications and/or made a proposal of new classification. The trias, abdominal
Pancreaticobiliary maljunction (PBM) is an uncommon congenital anomaly of the pancreatic and biliary ductal system, defined as a union of the pancreatic and biliary ducts located outside the duodenal wall. According to the Komi classification of PBM, the common bile duct (CBD) directly 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)
Pancreaticobiliary maljunction (PBM) is frequently associated with biliary cancer due to reflux of pancreatic enzymes into the choledochus, and even after surgery to correct the PBM such patients still have a risk of residual bile duct cancer. Here, we report the case of a 59-year-old female with
OBJECTIVE
To discuss the imaging anatomy about pancreaticobiliary ductal union, occurrence rate of pancreaticobiliary maljunction (PBM) and associated diseases in a Chinese population by using magnetic resonance cholangiopancreatography (MRCP).
METHODS
Data were collected from 694 patients who
