Clinical value of indwelling cutting with guidewire in difficult intubation of pancreatic duct for chronic pancreatitis / 中华消化内镜杂志

ABSTRACT

Objective:To evaluate the safety and efficacy of indwelling cutting with guidewire in treatment of difficult pancreatic duct stricture.Methods:A retrospective study was performed on the data of patients with chronic pancreatitis, who failed to implant pancreatic duct stent by endoscopic retrograde cholangiopancreatography (ERCP) and whose narrow pancreatic duct only allowed the guidewire to pass through, in Nanjing Drum Tower Hospital from November 2017 to April 2019. The dilatation effect of guidewire indwelling on difficult pancreatic duct stenosis was studied. The duration of guidewire indwelling, the success rate of stent re-implantation, the level of postoperative amylase, recent complications, and follow-up results were analyzed.Results:A total of five patients received indwelling guidewire after failure of dilation of pancreatic duct stenosis during ERCP. After 2.4 days of mean indwelling time, all patients received re-ERCP. The narrow pancreatic duct was successfully expanded and the stent was placed. In terms of complications, only one patient suffered from acute pancreatitis after the first ERCP, and was improved after medical treatment.Conclusion:Guidewire indwelling is a new simple, safe, and effective method for dilatation of pancreatic duct stenosis, and has important clinical value in the management of difficult intubation of pancreatic duct in chronic pancreatitis.
