OBJECTIVE: We evaluated the ability of endoscopic ultrasonography to predict likelihood of stricture formation in patients with corrosive esophagitis. METHODS: Consecutive patients with esophagitis resulting from alkaline or acid chemical ingestion (n = 11) were evaluated prospectively by endoscopic ultrasonography between hospital days 4 and 12. Findings for the most severe lesion were classified according to the appearance of the muscular layers: distinct muscular layers without thickening (grade 0); distinct muscular layers with thickening (grade I); obscured muscular layers with indistinct margins (grade II); and muscular layers that could not be differentiated (grade III). Findings were also classified according to whether apparent damage to muscular layers in the worst-appearing image involved part of the circumference (type a) or the whole circumference (type b). Implications of these findings for subsequent stricture formation were then evaluated. RESULTS: Stricture formation did not occur in patients with grade 0 or grade I images; transient stricture formation occurred in a patient showing grade IIa. Stricture requiring repeated bougie dilation occurred in a patient showing grade IIIb. CONCLUSIONS: Endoscopic ultrasonographic images presumed to reflect the destruction of muscular layers (grades II to III), as opposed to only edema (grade I), may be associated with stricture formation. This modality can accurately visualize deep lesions in corrosive esophagitis, making it prognostically useful.
