Abstract:
Objective To study the detection rate of early esophageal carcinoma using magnifying endoscopy,and to evaluate the relationship between the imaging patterns of microvasculature change and his- tological diagnosis.Methods Two hundred and fourteen patients with esophageal mucosa roughness,ero- sion,plaque,abnormal color and indentation in conventional endoscopy and 16 healthy volunteers were en- rolled.The magnifying endoscopy images were graded as four patterns by intraepithelial papillary capillary loop(IPCL)changes after iodine dyeing.The biopsies underwent pathologic evaluation.The comparison be- tween the imaging patterns of endoscopy and histological diagnosiswas was evaluated.Results 80.4%(90/ 112)esophagitis was type 2,and 85.7%(12/14)early esophageal carcinoma was type 3 and type 4.The difference was significant between early esophageal carcinoma and normal mueosa(?~2=27.32,P
