 Background and Aim:Although the high diagnostic performance of magnifying endoscopy for diagnosing EGC(early gastric cancer)has been extensively established, whether this modality has changed our clinical practice remains unclear. Thus, this study aims to investigate the number of biopsies performed for the endoscopic diagnosis of one EGC in the routine upper GI endoscopic examination using magnifying endoscopy.

 Methods:We determined the number of biopsies/number of detected EGCs in consecutive endoscopic examinations performed by one experienced endoscopist using magnifying endoscopy.

 Results:The number of biopsies(n=34)/number of detected EGCs(n=9)was 3.8.

 Discussion:Mass screening endoscopy revealed that the number of biopsies/number of detected EGCs was 34.1(personal communication). Comparing our outcome with data obtained by mass screening endoscopy, magnifying endoscopy seemingly contributes to decreasing the number of biopsies needed for detecting one cancer.

 Conclusions:Magnifying gastroscopy could have changed our clinical practice because it can decrease the number of biopsies, that is, this modality can act as an optical biopsy.
