The intrapapillary capillary loop (IPCL) changes in superficial esophageal lesions

Abstract

The aims of this study were to investigate intrapapillary capillary loops (IPCLs) of superficial esophageal lesions changes in different types classified by the Japan Esophageal Society classification. The calibers, areas, and densities of IPCLs were detected in 34 cases of esophageal lesions using immunohistochemical analysis. Statistically significant differences in calibers, areas, and densities of IPCLs were observed between type A, type B1/B2, and type B3 area (P < 0.001). In conclusion, the results of this observation showed the Japan Esophageal Society classification of IPCL would help endoscopists to diagnose the type and the invasion depth of lesion in esophagus, and decide the treatment strategy.
