Newest firstBackground Pancreaticobiliary maljunction (PBM) is a congenital disease in which the pancreatic and bile ducts fuse outside the duodenal wall. Congenital biliary dilatation (CBD) involves PBM and dilatation of the extrahepatic bile duct. The lack of Oddi sphincter action at the confluence results in the retrograde flow of pancreatic juice into the bile duct, placing patients with CBD at high risk of biliary carcin…
Open article record in new tab ↗Congenital biliary dilatation (CBD), frequently associated with pancreaticobiliary maljunction (PBM), predisposes patients to biliary tract malignancies due to chronic reflux of pancreatic juice into the biliary epithelium. Although biliary diversion reduces carcinogenic risk, malignancy may still arise many years after surgery. A 69-year-old woman underwent choledochal cyst excision and Roux-en-Y hepaticojejunost…
Background/purpose We evaluated the minimally invasive surgery for congenital biliary dilatation (CBD) in adults and children and analyzed the surgical outcomes, especially in children aged <6 years. Methods Characteristics and surgical outcomes of patients with CBD who underwent minimally invasive surgery at our hospital between 2013 and 2023 were retrospectively reviewed. Results Overall, 129 patients (89 childr…
Background Pancreaticobiliary maljunction (PBM) can be classified into two categories, PBM with congenital biliary dilatation (CBD) or PBM without biliary dilatation, and the management of PBM is often controversial. The treatment for PBM with CBD is prophylactic flow diversion surgery, and some authors have reported that the incidence of cancer after extrahepatic bile duct excision is less than 1%. A very rare ca…
Aim Pancreaticobiliary maljunction (PBM) with or without congenital biliary dilatation (CBD) is a risk factor for biliary tract cancer. We investigated long-term outcomes after biliary diversion operation with special reference to types of CBD. Methods Subjects comprised 40 adult patients who underwent biliary diversion operation for PBM without biliary tract cancer. Group A comprised 20 patients with type Ia or I…
Open article record in new tab ↗Background 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 fuses with the ventral pancreatic duct in all types. Pancreas divisum (PD) occurs when the ventral and dorsal ducts of…
Background The genesis of the "complex type" classification of pancreaticobiliary maljunction (PBM) is unclear, and the pancreaticobiliary anatomy is also varied according to each case. We encountered a patient with PBM and incomplete pancreatic divisum (PD). We herein discussed about the embryological etiology of pancreaticobiliary system predicted from PBM with incomplete PD. Case presentation A 67-year-old man…
Open article record in new tab ↗We encountered a very rare case of bile duct carcinoma associated with congenital biliary dilatation (CBD) in a 16-year-old female who was admitted to our hospital because of right upper abdominal pain and vomiting. Abdominal computed tomography demonstrated a cystic dilatation of the common bile duct measuring 7 cm in diameter and two enhanced tumors 4 cm in diameter located in the inferior bile duct and middle b…
Open article record in new tab ↗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 suspect…
