研究目的: |
1.主要目标:验证可降解胆道封堵器代替常规胆道引流在PTCS术后减少并发症、促进快速康复及降低结石复发率的临床疗效与安全性。 2.次要目标:评估可降解胆道封堵器对患者术后生活质量、住院时间及医疗成本的影响,进一步优化胆道手术术后管理策略。 |

|
Objectives of Study: |
1. Primary Objective: To evaluate the clinical efficacy and safety of a biodegradable biliary blockage as an alternative to conventional biliary drainage in reducing postoperative complications, accelerating recovery, and decreasing stone recurrence rates following percutaneous transhepatic cholangioscopy (PTCS). 2. Secondary Objectives: To assess the impact of the biodegradable biliary blockage on postoperative quality of life, hospital stay duration, and medical costs, thereby optimizing postoperative management strategies for biliary tract surgery. |

随机方法(请说明由何人用什么方法产生随机序列): |
采用分层简单随机分配方法,按照中心进行分层,其中四川大学华西医院和成飞医院各40例,遂宁市中心医院10例,中心剩余10例,均按照1:1使用SPSS进行随机分组,随机化种子分别为20231201、20241202、20241203、20241204,制作随机化信封,中心剩余指标用于调整各中心纳入情况。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Stratified simple randomization was performed with center-based stratification, allocating 40 cases each to West China Hospital of Sichuan University and Chengfei Hospital, 10 cases to Suining Central Hospital, and reserving 10 cases for additional centers. All centers followed 1:1 randomization using SPSS with distinct random seeds (20231201, 20241202, 20241203, 20241204). Opaque randomization envelopes were prepared, with the reserved quota allowing for adaptive adjustment of enrollment across centers. |
