Significance of endoscopic appearance of areae gastricae in the diagnosis of chronic atrophic fundic gastritis (CAFG) was investigated by image-enhanced endoscopy. Materials and Methods:  Endoscopic images of the corpus lesser curvature were studied in 50 patients with CAFG. Extent of CAFG was evaluated with autofluorescence imaging endoscopy. The areae gastricae pattern was evaluated with 0.2% indigo carmine chromoendoscopy. Micro-mucosal structure was examined with magnifying chromoendoscopy and narrow band imaging. Results:  In patients with small extent of CAFG, polygonal areae gastricae separated by a narrow intervening part of areae gastricae was observed, whereas in patients with wide extent of CAFG, the size of the areae gastricae decreased and the width of the intervening part of areae gastricae increased (p < 0.001). Most areae gastricae showed a foveola-type micro-mucosal structure (82.7%), while intervening part of areae gastricae had a groove-type structure (98.0%, p < 0.001). Groove-type mucosa had a higher grade of atrophy (p < 0.001) and intestinal metaplasia (p < 0.001) compared with foveola type. Conclusions:  As extent of CAFG widened, multifocal groove-type mucosa that had high-grade atrophy and intestinal metaplasia developed among areae gastricae and increased along the intervening part of areae gastricae. Our observations facilitate our understanding of the development and progression of CAFG. en-copyright= kn-copyright= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UedoNoriya en-aut-sei=Uedo en-aut-mei=Noriya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshiharaRyu en-aut-sei=Ishihara en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NagaiKengo en-aut-sei=Nagai en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuiFumi en-aut-sei=Matsui en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtaTakashi en-aut-sei=Ohta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HanafusaMasao en-aut-sei=Hanafusa en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HanaokaNoboru en-aut-sei=Hanaoka en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakeuchiYoji en-aut-sei=Takeuchi en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=HigashinoKoji en-aut-sei=Higashino en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IishiHiroyasu en-aut-sei=Iishi en-aut-mei=Hiroyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TomitaYasuhiko en-aut-sei=Tomita en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TatsutaMasaharu en-aut-sei=Tatsuta en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=YamamotoKazuhide en-aut-sei=Yamamoto en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil= kn-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=3 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=4 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=5 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=6 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=7 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=8 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=9 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=10 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=11 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=12 en-affil= kn-affil=Department of Pathology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=13 en-affil= kn-affil=Department of Gastrointestinal Oncology, Osaka Medical Center for Cancer and Cardiovascular Diseases affil-num=14 en-affil= kn-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences en-keyword=Chronic atrophc fundic gastritis kn-keyword=Chronic atrophc fundic gastritis en-keyword=image enhanced endoscopy kn-keyword=image enhanced endoscopy en-keyword=areae gastricae kn-keyword=areae gastricae en-keyword=magnified endoscopy kn-keyword=magnified endoscopy en-keyword=narrow band imaging kn-keyword=narrow band imaging END
