Summary
Brief summary (as posted)
The aim of the present study was to assess whether it was necessary to conduct magnifying endoscopy with narrow band imaging (ME-NBI) targeted biopsy compared with endoscopic forceps biopsy (EFB) from white light endoscopy in diagnosing early gastric cancer (EGC). Meanwhile, the investigators proposed the most cost-effective way to diagnose EGC.

- Suspected EGC group
- description
- Participants with suspected EGC from white light endoscopy were enrolled.The endoscopist first used white light endoscopy to identify suspected gastric lesions and assessed lesions carefully with magnifying view, non-magnifying NBI view and ME-NBI view in sequence. After assessing suspected EGC in ME-NBI view, ME-NBI targeted biopsy was performed where abnormal phenomenon was identified in ME-NBI view.

- description
- EFB and ME-NBI targeted biopsy and final resected specimens were assessed according to the Vienna classification. Suspected lesions were assessed in ME-NBI view according to the diagnostic classification proposed by Yao and Ezoe et al. However, little different from their classification, lesions were classified into positive HGN phenomenon, indefinite and suspected HGN, negative HGN phenomenon. After that, ME-NBI targeted biopsy was performed where abnormal or suspected phenomenon was observed. Compared with final pathology of endoscopic submucosal dissection (ESD) or surgery specimens, sensitivity of EFB, ME-NBI, ME-NBI targeted biopsy, ME-NBI combined EFB and ME-NBI combined targeted biopsy was calculated. Accuracy of EFB and ME-NBI targeted biopsy was compared using McNemar test. The same method was used to compare ME-NBI combined EFB and ME-NBI combined targeted biopsy.
