Intraductal infusion surgery. (a) Schematic of the organization of the infusion. (b) Actual organization of the equipment. (c) A microclamp is placed on the bile duct near the liver to prevent perfusion of the liver. (d) A 30-gauge needle is used to make a small duodenal hole opposite to the sphincter of Oddi. Next, a 31-gauge blunt-ended catheter is carefully placed into the biliary-pancreatic duct through the sphincter of Oddi in the duodenum. (e) The tip of the catheter should be positioned at the origin of the pancreas branch in the biliary-pancreatic duct. (f) The catheter can be then secured with the second microclamp at the sphincter of Oddi to prevent backflow into the duodenum. Yellow arrows point to the biliary-pancreatic duct, green arrows point to the tip of the catheter in the biliary-pancreatic duct, blue arrows point to the sphincter of Oddi and red arrows point to the pancreatic duct branch in the biliary-pancreatic duct.
