Image-enhanced endoscopy (IEE) has advanced gastrointestinal disease diagnosis and treatment. Traditional white-light imaging has limitations in detecting all gastrointestinal diseases, prompting the development of IEE. In this review, we explore the utility of IEE, including texture and color enhancement imaging and red dichromatic imaging, in pancreatobiliary (PB) diseases. IEE includes methods such as chromoendoscopy, optical-digital, and digital methods. Chromoendoscopy, using dyes such as indigo carmine, aids in delineating lesions and structures, including pancreato-/cholangio-jejunal anastomoses. Optical-digital methods such as narrow-band imaging enhance mucosal details and vessel patterns, aiding in ampullary tumor evaluation and peroral cholangioscopy. Moreover, red dichromatic imaging with its specific color allocation, improves the visibility of thick blood vessels in deeper tissues and enhances bleeding points with different colors and see-through effects, proving beneficial in managing bleeding complications post-endoscopic sphincterotomy. Color enhancement imaging, a novel digital method, enhances tissue texture, brightness, and color, improving visualization of PB structures, such as PB orifices, anastomotic sites, ampullary tumors, and intraductal PB lesions. Advancements in IEE hold substantial potential in improving the accuracy of PB disease diagnosis and treatment. These innovative techniques offer advantages paving the way for enhanced clinical management of PB diseases. Further research is warranted to establish their standard clinical utility and explore new frontiers in PB disease management.
图像增强内镜检查(IEE)推动了胃肠疾病的诊断和治疗。传统白光成像在检测所有胃肠疾病方面存在局限性,促使了IEE的发展。在本综述中,我们探讨了IEE在胰腺胆管(PB)疾病中的应用,包括纹理和颜色增强成像以及红色双色成像。IEE包括诸如色素内镜检查、光学数字和数字方法等。色素内镜检查使用靛胭脂等染料,有助于勾勒病变和结构,包括胰/胆管空肠吻合术。诸如窄带成像等光学数字方法可增强黏膜细节和血管形态,有助于壶腹肿瘤评估和经口胆管镜检查。此外,红色双色成像因其特定的颜色分配,提高了深层组织中粗大血管的可视性,并以不同颜色和透视效果增强出血点,在内镜括约肌切开术后处理出血并发症方面证明是有益的。颜色增强成像作为一种新型数字方法,可增强组织纹理、亮度和颜色,改善PB结构(如PB开口、吻合部位、壶腹肿瘤和导管内PB病变)的可视化。IEE的进展在提高PB疾病诊断和治疗的准确性方面具有巨大潜力。这些创新技术提供了优势,为PB疾病的强化临床管理铺平了道路。有必要进行进一步研究以确立其标准临床应用,并探索PB疾病管理的新领域。
