AIM: To evaluate the effectiveness of trimodal imaging endoscopy (TME) to detect another lesion after endoscopic submucosal dissection (ESD) for superficial @entity356 (SGN). METHODS: Surveillance esophagogastroduodenoscopy (EGD) using a TME was conducted in 182 @entity1 that had undergone ESD for SGN. @entity2996 ( @entity2996 ) was conducted after white-light imaging (WLI). When SGN was suspicious, magnifying endoscopy with narrow-band imaging (ME-NBI) was conducted. Final diagnoses were made by histopathologic findings of biopsy specimens. The detection rates of lesions in WLI, @entity2996 , and NBI, and the characteristics of lesions detected by WLI and ones missed by WLI but detected by @entity2996 were examined. The sensitivity, specificity, and accuracy of endoscopic diagnosis using WLI, @entity2996 and ME-NBI were evaluated. RESULTS: In 242 surveillance EGDs, 27 lesions were determined pathologically to be @entity5 . Sixteen early @entity356 and 6 gastric @entity652 could be detected by WLI. Sixteen lesions were reddish and 6 were whitish. Five @entity356 were missed by WLI but were detected by @entity2996 , and all were whitish and protruded gastric @entity652 . There was a significant difference in color and pathology between the two groups (P = 0.006). Sensitivity, specificity and accuracy in ME-NBI were higher than those in both WLI and @entity2996 . Specificity and accuracy in @entity2996 were lower than those in WLI. CONCLUSION: Surveillance using trimodal imaging endoscopy might be useful for detecting another lesion after endoscopic submucosal dissection for superficial @entity356 .
