ABSTRACT

Catheterization of the pancreatic ducts is almost exclusively carried out by an endoscopic approach. Percutaneous pancreatic duct stenting is advocated as a last resort, when endoscopy has failed. The main indication for pancreatic duct stenting is a primary or intermediate treatment of pain, related to chronic pancreatitis and a therapeutic test prior to major surgery. A solitary or dominant ductal stricture, located in the head of the pancreas, represents the best indication. Other indications are intractable pain in pancreatic cancer, with dilated ducts or a postoperative anastomotic stenosis. A prerequisite for percutaneous puncture of the main pancreatic duct, with CT guidance, is a minimal diameter of 3 to 5 mm. The access route is predominantly anterior and transgastric. Stents with a diameter of 5 to 6 mm and a length of 2 to 4 cm are placed. Only a few case reports of the percutaneous stenting technique are available. The endoscopic literature reported an immediate pain relief in 94% and a long term benefit in 64% of the cases with chronic pancreatitis. The main drawback of placement of metal stents in the pancreatic duct is clogging, which is not significantly improved compared to the use of plastic stents.
