Abstract

Two patients with corrosive esophagitis caused by alkaline household agents were examined with endoscopic ultrasound using a 20-MHz probe. In the first case, endoscopic ultrasound revealed circumferentially thickened mucosa and muscularis propria, and lack of differentiation between the mucosa and submucosa. However, esophageal stricture did not develop during 3 months of follow-up, suggesting that the deep lesion may have involved a narrow section of esophagus only. In the second case, a markedly thickened mucosa was seen, resulting in no sequelae. Endoscopic ultrasound offers a more accurate evaluation of the depth of the lesions in alkaline esophagitis compared to standard endoscopy or computed tomography. Longitudinal studies are needed to identify lesions at greatest risk for progression to stricture.
