研究目的:

本项目旨在对该人工智能辅助诊断系统进行进一步的前瞻性临床验证,以确定在临床实践中是否能有效协助内镜医生鉴别胃肠道间质瘤及平滑肌瘤,提高术前诊断准确率,以及进一步优化人工智能模型。  

Objectives of Study:

This project aims to further prospective clinical verification of the artificial intelligence-assisted diagnosis system. Furthermore, it can be analyzed whether it can effectively assist the endoscopist to identify gastrointestinal stromal tumors and leiomyomas in clinical practice, improve the accuracy of preoperative diagnosis, and further optimize Artificial intelligence model.

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

病理学诊断是诊断金标准。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Pathological diagnosis is the gold standard for the diagnosis.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

一个人工智能辅助超声内镜诊断系统 (由三组不同年资的内镜医师行超声内镜检查)

Index test:

An artificial intelligence assisted endoscopic ultrasound diagnosis system (Endoscopic ultrasonography was performed by three groups of endoscopists with different seniority).

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

病理学诊断为胃肠道间质瘤或平滑肌瘤患者。

例数:

Sample size:

60

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Patients with histological-confirmed gastrointestinal stromal tumor or leiomyomas.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

除间质瘤或平滑肌瘤以外的其他种类的胃肠道上皮下病变患者(例如,神经内分泌瘤、神经鞘瘤、异位胰腺、脂肪瘤)。

例数:

Sample size:

30

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

Patients with other types of gastrointestinal subepithelial lesions other than stromal tumors or leiomyomas(For example, neuroendocrine tumor, schwannoma, heterotopic pancreas, lipoma).
