Figure 1 Minor papilla cannulation and fluoroscopic confirmation in Case 1. A: Endoscopic view of precut sphincterotomy at the minor papilla; the preplaced biliary stent serves as a landmark, with coordinated instrument assistance; B: Intraprocedural fluoroscopic confirmation of guidewire advancement to the pancreatic tail with adjusting patient position to optimize fluoroscopic field; C: Fluoroscopic view of the double-guidewire technique with changing to cannulate via the minor papilla under the reference marker of indwelling biliary guidewire; D: Fluoroscopic confirmation after the stent placement, verifying correct stent positioning and unobstructed biliary drainage.
