Efficacy and safety of early pancreatic duct stenting for unresectable pancreatic cancer: A randomized controlled trial

Figure 1 Endoscopic procedure. A: The duodenal papilla can be seen under duodenoscope; B: After successful pancreatic duct cannulation, a pancreatic stent duct was placed through the guidewire; C: Radiological image of the self-expandable metallic biliary stent after deployment; D: The pancreatic stent duct and self-expandable metallic biliary stent were successfully placed under duodenoscope.

Figure 2 Consort flowchart. The double-stent group underwent endoscopic retrograde cholangiopancreatography with a fully-covered self-expandable metallic biliary stent and a pancreatic duct stent, while the single-stent group underwent a fully-covered self-expandable metallic biliary stent only. CPN: Celiac plexus neurolysis; ERCP: Endoscopic retrograde cholangiopancreatography.
