研究目的: |
1. 主要目的:评价新型自排式胆道螺旋支架用于ERCP 取石术后临时性胆管引流的有效性(术后胆管炎/术后胰腺炎发生率)是否非劣于鼻胆管临时引流的有效性。 2. 次要目的:评价新型自排式胆道螺旋支架和鼻胆管在ERCP 取石术后临时性胆管引流的安全性(支架相关消化道损伤、支架滞留、鼻胆管相关不良事件、出血)、支架排出时间、鼻胆管拔出时间、术后住院时间、医疗费用等。 |

Objectives of Study: |
1. Primary Objective: to study if the temporary common bile duct draining efficacy, i.e. post-procedure cholangitis and pancreatis, of the novel biliary spontaneous dislodgement spiral stent is non-inferior to endoscopic nasobiliary drainage tube after complete removel of stones in the bile duct by ERCP. 2.Secondary Objective:to study the safety, i.e. stent-related injury of the GI tract, retention of the stent, nasobiliary tube-related adeverse events, bleeding, medical cost, and the time of stent evacuation, removal of nasobiliary tube and hospitalization. |

随机方法(请说明由何人用什么方法产生随机序列): |
先由不参与病例纳入的研究助理采用excel 生成2292 个随机数字(按患者入组顺序排列);再将随机数字从小到大排列,前1146 例归为螺旋支架组(A 组),后1146 例归为鼻胆管组(B 组);最后按照患者入组顺序从小到大重新排列。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A research assistant independent of this study generated a randomized sequence of 2292 numbers using Excel software, corresponding to the anticipated patient enrollment order. These numbers were subsequently sorted in ascending numerical order to create two balanced groups: the first 1146 numbers were allocated to the dislodgement spiral stent intervention (Experimental Group A), while the remaining 1146 numbers were assigned to the nasobiliary tube comparator (Control Group B). |
