研究目的: |
1.明确胃癌根治术后胆囊结石发生的时间特点及发生规律。 2.比较不同UDCA用药时程在预防胆囊结石形成方面的效果。 3.探索胃癌术后预防胆囊结石的最佳UDCA用药时间。 4.为胃癌术后胆囊结石的规范化预防提供循证医学证据。 5.优化胃癌围手术期管理策略,减轻患者经济及心理负担。 |
||||||||||||||||||||||
|
Objectives of Study: |
1.Clarify the temporal characteristics and occurrence patterns of gallbladder stones after radical gastrectomy for gastric cancer. 2.Compare the effects of different durations of UDCA administration in preventing the formation of gallbladder stones. 3.Explore the optimal administration time of UDCA for the prevention of gallbladder stones after gastric cancer surgery. 4.Provide evidence-based medical evidence for the standardized prevention of gallbladder stones after gastric cancer surgery. 5.Optimize the perioperative management strategies for gastric cancer to alleviate the economic and psychological burdens on patients. |

随机方法(请说明由何人用什么方法产生随机序列): |
由独立统计人员利用统计软件(如SPSS或R软件)生成随机数字表,并按照1:1:1比例将符合纳入标准的患者随机分配至三组:3个月用药组、6个月用药组及12个月用药组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Independent statisticians generated random number tables using statistical software such as SPSS or R software, and randomly assigned patients who met the inclusion criteria to three groups at a ratio of 1:1:1: the 3-month medication group, the 6-month medication group, and the 12-month medication group. |

盲法: |
本研究采用开放标签研究设计(open-label study),即患者及研究医生均知晓具体用药方案。为减少观察偏倚,本研究在以下环节实施评价者盲法(blinded outcome assessment): 影像学评价盲法:所有腹部超声检查结果由影像科医师进行判读,影像科医师对患者的分组情况保持盲态。 数据统计分析盲法:在数据分析阶段,统计人员在不知道各组具体干预措施的情况下进行统计分析,以减少分析偏倚。 |
|
Blinding: |
This study adopted an open-label study design, meaning that both the patients and the study doctors were aware of the specific medication regimens. To reduce observational bias, in this study, the evaluator blinding (blinded outcome assessment) was implemented in the following aspects: imaging evaluation blinding: all abdominal ultrasound examination results were interpreted by radiologists, and radiologists remained blind to the grouping of patients. Blind data statistical analysis method: During the data analysis stage, statisticians conduct statistical analysis without knowing the specific intervention measures of each group to reduce analytical bias. |
