研究目的:

已有研究显示,人工智能系统在内镜诊断及操作质量管理中具有应用潜力。本研究拟开展一项前瞻性、单中心、随机对照试验,系统比较“AI 辅助系统联合传统带教培训”与“单纯传统带教培训”两种模式下超声内镜医师的操作表现差异。研究将通过评估总体能力(GOA)达标率、学习曲线演变及操作效率等关键指标,验证人工智能辅助系统在超声内镜规范化培训中的可行性及临床实用价值。  

Objectives of Study:

Previous studies have demonstrated the potential application of artificial intelligence (AI) systems in endoscopic diagnosis and quality management of endoscopic procedures. This study aims to conduct a prospective, single-center, randomized controlled trial to systematically compare the performance of endoscopic ultrasound (EUS) trainees under two training methods: "AI-assisted system combined with traditional mentorship" versus "traditional mentorship alone." The study will evaluate key outcomes including the rate of achieving global overall competence (GOA), evolution of learning curves, and operational efficiency, in order to verify the feasibility and clinical utility of an AI-assisted system in standardized EUS training.

排除标准:

超声内镜医生排除标准: (1)已掌握超声内镜独立操作技能的高级超声内镜医师; (2)因个人原因无法完成研究培训或观察流程的医师。 患者排除标准: (1)已参加其它临床试验,签署知情同意书并在其它临床试验的随访期内; (2)已参加药物临床试验,并且在试验药物或对照药物的洗脱期内; (3)超声内镜检查绝对禁忌症; (4)最近 5 年存在药物或酒精滥用情况或有心理障碍; (5)孕期或哺乳期妇女; (6)出血风险或血小板减少; (7)既往消化系统手术史; (8)严重的内科疾病; (9)上消化道梗阻; (10)既往麻醉药过敏反应史; (11)晚期肿瘤引起的上消化道解剖异常; (12)研究者认为受试者不适合接受超声内镜检查; (13)研究者认为受试者具有不适宜参加临床试验的高危疾病或其它特殊情况。

Exclusion criteria:

Exclusion Criteria for Endoscopic Ultrasound (EUS) Endoscopists: (1) Senior EUS endoscopists who have already mastered independent EUS operation skills; (2) Endoscopists unable to complete the training or observation procedures due to personal reasons. Exclusion Criteria for Patients: (1) Participation in another clinical trial, having signed an informed consent form, and still being within the follow-up period of that trial; (2) Participation in a drug clinical trial and currently within the washout period of the investigational or control drug; (3) Presence of absolute contraindications to endoscopic ultrasonography; (4) History of substance or alcohol abuse, or psychiatric disorders within the past five years; (5) Pregnant or lactating women; (6) Increased bleeding risk or thrombocytopenia; (7) History of gastrointestinal surgery; (8) Presence of severe internal medical diseases; (9) Upper gastrointestinal obstruction; (10) History of allergic reactions to anesthetic agents; (11) Anatomical abnormalities of the upper gastrointestinal tract caused by advanced malignancies; (12) Determination by the investigator that the subject is unsuitable for EUS examination; (13) Determination by the investigator that the subject has high-risk conditions or special circumstances that make participation in the clinical trial inappropriate.

公开/Public

盲法:

由于培训方式的性质不同,研究实施阶段受试者及带教导师无法盲法。但评估环节将采用单盲评估:所有操作视频及 EUS-TEESAT 评分过程将由未参与培训、未知分组信息的资深 EUS专家独立完成。研究数据录入与统计分析阶段同样保持分组编码匿名,仅在最终统计分析完成后进行解盲。

Blinding:

Due to the nature of the intervention, blinding of trainees and mentors will not be feasible. However, a single-blind assessment will be implemented: All recorded EUS procedures and TEESAT scoring will be independently evaluated by experienced EUS experts who are blinded to group allocation and not involved in the training process. During data entry and statistical analysis, all group codes will remain blinded. Unblinding will occur only after completion of the final analysis.
