We describe here our experience of successful closure of a lesion of the main pancreatic duct by means of a constructed S-type pancreatic stent.
A 67-year-old woman with an abnormal biliary-pancreatic junction and a tumor of the gallbladder underwent cholecystectomy plus R2, extrahepatic cholangiectomy, hepatocholangiojejunostomy, and Roux-en-Y reconstruction on 2 February 2001. In the postoperative period pancreatic fistulization occurred, with endoscopic retrograde cholangiopancreatography (ERCP) revealing a leak of contrast medium medially to the common bile duct. A pancreatic stent (GEPD, 7-Fr; Wilson-Cook, Winston-Salem, North Carolina, USA) was therefore put in place. Unfortunately, the stent migrated 2 days later, and so it was replaced with a constructed pancreatic stent with a shape which approximated to that of the main pancreatic duct (Figure [1]) (constructed S-type pancreatic stent, 7-Fr; Olympus, Tokyo, Japan). This was followed by excellent progress, which allowed removal of the stent and discharge of the patient from hospital 6 weeks later.
In our department, we have been using straight biliary stents (PBD, Olympus; or GEPD, Wilson-Cook). However, as the main pancreatic duct has characteristic bends within the pancreatic head, we were not able to stabilize the fixation of stents and consequently they migrated. Because of this, in 1998 we constructed a stent with a shape which approximated to that of the main pancreatic duct. The tip of the stent tapers and sideholes have been added. The two bends in the stent correspond to the shape of the main pancreatic duct. The material used is a polyolefin-based elastomer, with a flexibility which is 50 - 70 % greater than that of PBD; this is important for the adaptation of the stent to interindividual variability in the shape of the main pancreatic duct (Figure [2]). We applied the stent in the case of a patient with chronic pancreatitis, with excellent results [1] [2] [3]. Unfortunately, because of the migration of a GEPD stent the patient had become febrile, so we replaced it with an S-type stent and this resulted in remission. The stent closed the lesion of the main pancreatic duct, protected the flow through the duct, and also stayed in place. Based on these outcomes we concluded that the constructed S-type pancreatic stent was effective in the treatment of postoperative pancreatic fistula.
