Abstract:
Objective To analyze endoscopic ultrasonography (EUS) image of esophageal granular cell tumor (GCT) by computer image analysis software,and to explore its diagnostic and differential diagnostic value.Methods Eight esophageal GCT and eight leiomyomas confirmed by pathological and immunohistochemical examination were collected,mean gray value and gray value standard deviation of EUS image of the leisons were analyzed by computer image analysis software.The comparison of two groups was analyzed by t test.Results The endoscopic and ultrasound images of esophageal GCT and leiomyomas were similar.The mean gray value of EUS image of esophageal GCT and esophageal leiomyomas was 67.51 and 51.76,the difference was statistically significant (t=2.225,P=0.043).However,there was no significant difference in the standard deviation of gray value (13.54 vs 13.12,t=0.225,P=0.825).Conclusion The accuracy of GCT diagnosed by EUS could be increased by comparing the gray values of EUS images of esophageal GCT and leiomyomas.
