Abstract
Background: To our knowledge this is the first report describing the relation between the form of the duodenal papilla and the pancreaticobiliary maljunction (PBM). Methods: The duodenal papilla was studied endoscopically in 46 patients with PBM and in 80 patients without PBM. Results: The duodenal papilla was classified into three types by three independent endoscopists. Conclusion: The oral protrusion of the duodenal papilla in patients with PBM was shorter or absent compared with the duodenal papilla in patients without PBM.
