Introduction
Anomalous pancreaticobiliary junction (APBJ) is the term used to describe anatomical variants of pancreatic and biliary ductal junctional anatomy. Patients have junction of the pancreatic and bile ducts located outside the duodenal wall, forming a long common channel. We report our findings and clinical outcomes in a North American series of patients with APBJ undergoing ERCP.
Methods
Retrospective chart review.
Results
We reviewed 2,218 ERCP performed on 1,050 patients. Twelve patients (1.1%) with APBJ were identified (5F, 7M). No patient had an associated choledochocele. Mean age was 53.2 (range 17–85). A total of 43 ERCP procedures were performed on these 12 patients. All patients experienced passive pancreatography. No patient developed post-ERCP pancreatitis. Only one patient had a history of antecedent pancreatitis.
Conclusions
In North American patients undergoing ERCP, 1.1% of patients had APBJ. Our study population was predominately Caucasian, male, and in all but one patient lacked a history of prior pancreatitis. No patient developed post-ERCP pancreatitis. This suggests that APBJ may have different clinical manifestations in a North American population when compared to Asian populations.
