Abstract

Gallstone disease is a common condition affecting a substantial number of individuals globally. The risk factors for gallstones include obesity, rapid weight loss, diabetes, and genetic predisposition. Gallstones can lead to serious complications such as calculous cholecystitis, cholangitis, biliary pancreatitis, and an increased risk for gallbladder (GB) cancer. Abdominal ultrasound (US) is the primary diagnostic method due to its affordability and high sensitivity, while computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) offer higher sensitivity and specificity. This review assesses the diagnostic accuracy of machine learning (ML) technologies in detecting gallstones. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting systematic reviews and meta-analyses. An electronic search was conducted in PubMed, Cochrane Library, Scopus, and Embase, covering literature up to April 2024, focusing on human studies, and including all relevant keywords. Various Boolean operators and Medical Subject Heading (MeSH) terms were used. Additionally, reference lists were manually screened. The review included all study designs and performance indicators but excluded studies not involving artificial intelligence (AI)/ML algorithms, non-imaging diagnostic modalities, microscopic images, other diseases, editorials, commentaries, reviews, and studies with incomplete data. Data extraction covered study characteristics, imaging modalities, ML architectures, training/testing/validation, performance metrics, reference standards, and reported advantages and drawbacks of the diagnostic models. The electronic search yielded 1,002 records, of which 34 underwent full-text screening, resulting in the inclusion of seven studies. An additional study identified through citation searching brought the total to eight articles. Most studies employed a retrospective cross-sectional design, except for one prospective study. Imaging modalities included ultrasonography (four studies), computed tomography (three studies), and magnetic resonance cholangiopancreatography (one study). Patient numbers ranged from 60 to 2,386, and image numbers ranged from 60 to 17,560 images included in the training, validation, and testing of the diagnostic models. All studies utilized neural networks, predominantly convolutional neural networks (CNNs). Expert radiologists served as the reference standard for image labelling, and model performances were compared against human doctors or other algorithms. Performance indicators such as sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were commonly used. In conclusion, while the reviewed machine learning models show promising performance in diagnosing gallstones, significant work remains to be done to ensure their reliability and generalizability across diverse clinical settings. The potential for these models to improve diagnostic accuracy and efficiency is evident, but the careful consideration of their limitations and rigorous validation are essential steps toward their successful integration into clinical practice.

摘要

胆结石病是一种常见疾病,全球大量人群受其影响。胆结石的风险因素包括肥胖、快速体重减轻、糖尿病和遗传易感性。胆结石可导致严重并发症,如结石性胆囊炎、胆管炎、胆源性胰腺炎以及胆囊癌风险增加。腹部超声(US)因其价格低廉和高敏感性,是主要的诊断方法,而计算机断层扫描(CT)和磁共振胰胆管造影(MRCP)具有更高的敏感性和特异性。本综述评估了机器学习(ML)技术在检测胆结石方面的诊断准确性。本系统综述遵循系统评价和Meta分析的首选报告项目(PRISMA)指南来报告系统评价和Meta分析。在PubMed、Cochrane图书馆、Scopus和Embase中进行了电子检索,涵盖截至2024年4月的文献,重点是人体研究,并包括所有相关关键词。使用了各种布尔运算符和医学主题词(MeSH)术语。此外,还对手动筛选参考文献列表。该综述纳入了所有研究设计和性能指标,但排除了不涉及人工智能(AI)/ML算法、非成像诊断方式、微观图像、其他疾病、社论、评论、综述以及数据不完整的研究。数据提取涵盖研究特征、成像方式、ML架构、训练/测试/验证、性能指标、参考标准以及诊断模型报告的优缺点。电子检索产生了1002条记录,其中34条进行了全文筛选,最终纳入7项研究。通过引文检索确定的另一项研究使文章总数达到8篇。除一项前瞻性研究外,大多数研究采用回顾性横断面设计。成像方式包括超声检查(4项研究)、计算机断层扫描(3项研究)和磁共振胰胆管造影(1项研究)。患者人数从60到2386不等,图像数量从60到17560张,这些图像包含在诊断模型的训练、验证和测试中。所有研究都使用了神经网络,主要是卷积神经网络(CNN)。专家放射科医生作为图像标记的参考标准,并将模型性能与人类医生或其他算法进行比较。常用的性能指标如敏感性、特异性、阳性预测值(PPV)和阴性预测值(NPV)。总之,虽然所综述的机器学习模型在诊断胆结石方面显示出有前景的性能,但仍有大量工作要做,以确保其在不同临床环境中的可靠性和可推广性。这些模型提高诊断准确性和效率的潜力是明显的,但仔细考虑其局限性并进行严格验证是将其成功整合到临床实践中的关键步骤。
