Probe based confocal laser endomicroscopy (pCLE) is a new endoscopic diagnostic method which integrates micro-imaging technology into endoscopy and can identify the morphological structure of particular tissue surface, so that the ongoing procedure of endoscopy can make the histopathological diagnosis. pCLE has the "optical biopsy" function, avoids shortcomings in physical biopsies such as being time-consuming, cumbersome, and prone to sampling error, and thus improves the diagnostic accuracy and efficiency. The field of research of pCLE as a new endoscopic imaging technology has been expanded from the digestive cavity structure to the respiratory system and urinary system. This article reviews the progress of research and clinical application of pCLE.

与其他常用的成像技术相比, Lim等[18]发现pCLE和WLE的敏感性、特异性和准确性分别为88.6%、90.3%、89.3%和27.3%、96.8%、56.0%. pCLE在腺瘤的诊断中显示了比传统活检更高的准确性(91.7% vs 85.2%)[19]. 有研究者以组织病理学检查为金标准对比了窄带成像(narrow band imaging, NBI), 自体荧光(autofluorescence imaging, AFI), pCLE和WLE四种成像技术在胃黏膜肠化生的诊断差异[18]. 结果实时pCLE比WLE有更高的敏感性(90.9% vs 37.9%)和准确性(88.0% vs 64.8%), 和AFI相比, 其有更高的敏感性(90.0% vs 68.2%)、特异性(84.7% vs 69.5%)和准确性(88.0% vs 68.8%), 和NBI相比, pCLE在这三个指标上与其相似.
