Background: Although annular pancreas concurrent with pancreaticobiliary maljunction has rarely been reported, some reports have pointed out a possibility that both anomalies have a common pathogenesis in pancreatic development. We herein report a case with pancreaticobiliary maljunction diagnosed long after surgical treatment for annular pancreas.
Case Presentation: A 34-year-old female, with a surgical history of duodenal obstruction due to annular pancreas in the neonatal period, was referred to our hospital for further examination of chronic pancreatitis. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed choledocholithiasis, pancreatic lithiasis, and pancreaticobiliary maljunction without biliary dilatation. Choledocholithotomy and cholecystectomy were performed, and highly elevated levels of amylase in bile from the common bile duct were found intraoperatively.
Conclusion: The present case highlights a possible association of pancreaticobiliary maljunction in a patient with annular pancreas.

Pancreaticobiliary maljunction (PBMJ) has a long common channel (CC) that causes pancreaticobiliary reflux (PBR), which has been implicated in gallstones, cholangiocarcinoma, and pancreatitis. By contrast, PBR has occurred in cases with normal and longer CCs than normal but shorter than PBMJ. This pathophysiology has been primarily reported in adults and rarely in children.

We present the case of a 54-year-old woman who was diagnosed with intraductal papillary neoplasm of the bile duct (IPNB) in the remnant intrapancreatic bile duct, 37 years after surgery for congenital biliary dilatation. Endoscopic ultrasonography revealed a papillary, low-echoic mass in the intrapancreatic bile duct, and peroral cholangioscopy revealed a papillary mucosa. A pancreaticoduodenectomy was performed, and the patient was pathologically diagnosed with type 1 pancreatobiliary-type IPNB with associated invasive carcinoma.

Rationale: This case report aims to enhance understanding of pancreatobiliary maljunction (PBM) and promote more proactive treatment.
Patient Concerns: The patient, a 24-year-old Chinese female, was admitted to the hospital on April 7, 2020, due to "recurrent abdominal pain for over 2 years, with a recent episode accompanied by nausea and vomiting for 1 day." She had a previous history of gallstones.

Background: In patients with pancreaticobiliary maljunction complicated by congenital biliary dilatation, the pancreatic enzyme flows back into the bile, leading to bile duct carcinogenesis. Although the biliary tract resection and reconstruction is well documented to decrease the rate of malignancy, cancer occurrence has been reported in the residual intrahepatic or intrapancreatic bile duct, even after resection. We report a case of multiple biliary tract cancers in the liver complicated by congenital biliary dilatation, whose tumor lesions were resected en bloc without disconnecting the biliary tract by simultaneous pancreatoduodenectomy and living donor liver transplantation.

Pancreaticobiliary maljunction (PBM) is a congenital anomaly where the pancreatic and bile ducts join outside the duodenal wall, resulting in formation of an elongated common channel. In normal physiology, the sphincter of Oddi regulates the junction between the pancreatic and bile ducts. Individuals with PBM lack this regulatory mechanism resulting in reflux of pancreatic juices into the biliary tract.
