丝留置切割法在慢性胰腺炎胰管困难性 插管中的价值初探

Clinical value of indwelling cutting with guidewire in difficult intubation of pancreatic duct for chronic pancreatitis

摘要:

目的 评价导丝留置切割法对困难性胰管狭窄再扩张的安全性及有效性。方法 收集2017年11月—2019年4月期间在南京鼓楼医院消化内科行经内镜逆行胰胆管造影术(endoscopic retrograde cholangiopancreatography, ERCP) 胰管支架置入失败，狭窄胰管仅能允许导丝通过并留置导丝的慢性胰腺炎患者资料，探讨导丝留置切割对于困难性胰管狭窄的扩张作用，分析导丝留置时间、再次ERCP胰管支架置入成功率、术后淀粉酶水平、导丝留置近期并发症及随访结果。结果 共计5例患者ERCP术中胰管狭窄扩张失败后留置导丝，平均留置导丝2.4 d后，再次行ERCP，胰管狭窄部位均可成功扩张,并置入胰管支架。并发症发生方面，仅有1例患者首次ERCP术后发生急性胰腺炎，经过对症治疗好转。结论 导丝留置切割是一种简单、安全、有效的胰管狭窄扩张新方法，对处理慢性胰腺炎胰管困难性插管具有重要的临床价值。

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.
