Stent Implantation for Puncture Drainage of Pancreatic Pseudocysts Clinical Effects of Endoscopic Ultrasonography - guided Plastic

Abstract：Objective To explore the effect and complication of endoscopic ultrasonography - guided(EUS -guided)plastic stent implantation for puncture drainage of pancreatic pseudocysts. Methods Clinical data of 9 pa-tients with severe pancreatitis and pancreatic pseudocysts from Apr. 2012 to Jan. 2014 were analyzed retrospectively. Lesion sites were determined and appropriate puncture point was chosen by color Doppler line shape endoscopic ultra-sonography scan. Guidewire was placed into the pseudocyst. A tiny incision was made on the capsule wall of the pseud-ocyst by disposable needle knife. Then double pigtail stents internal drainage(1 or 2 depending on the state of illness) were put after dilated into the pseudocyst. Patients were followed up after the first and third month. The stent was pulled out after pancreatic pseudocysts disappeared. All patients were examined by CT and B - ultrasonic as well as 1 year follow - up. Results The success rate of drainage procedure was 100% . 2 of 9 patients had a fever two days af-ter surgery;postoperative infection of the pseudocysts was the cause probably. 1 patient cured by intravenous infusion of antibiotics sensitive,and fever of the other patient was controlled by intravenous infusion of imipenem. Plastic stent implantation 1 patient was pulled out in local hospital after one month and pseudocyst relapsed three months later. Conclusion EUS - guided puncture drainage can be used to treat pancreatic pseudocysts with acceptable feasibility, efficacy and safety. More plastic stents can be placed if possible,which is worthy of promoting in clinical.
