Trans-drain Occlusion for Postoperative Pancreatic Fistula- A Double Blind Randomized Clinical Trial

"1. Fistulography: an 18G needle is inserted into the tube and diluted contrast medium is slowly injected into the tube.~2. Trans-drain occlusion: a 0.035-inch guidewire is inserted via the puncture needle. The drain tube is removed, cut at 4 cm proximal to the skin fixation site, and preserved for reinsertion. After inserting a 40cm 5Fr KMP catheter over the guidewire, the guidewire is removed. Afte rinsing the KMP catheter with 3ml 5% glucose water, withdraw the catheter and simultaneously inject glue (33%, 1:2, 0.5ml of NBCA + 1ml Lipiodol) into the catheter until the proximal 5cm of the catheter remains inside the tract. The guidewire is re-inserted through the catheter, and then the original drain tube is re-inserted over the guidewire. The guidewire is removed and the drain is fixed."
