 On the basis of our experience of high-magnifying endoscopy of fine gastric mucosal pattern, fine regenerative mucosal patterns were observed and classified in the healing process of gastric ulcer.

 The healing process was divided into regenerative stage (R) with ulceration and epithelization stage (E) without white coating. Furtheremore, they were classified into seven types, R0, R1, R2, E1, E2, E3 and E4 (Table 2, Fig. 2, 3). Generally, A1 stage of Sakita's classification showed R0, A2 showed R1, H1 and H2 showed R2, S1 showed E1 and E2, and S2 showed E3 and E4 from onset to healing (Table 3, 4).

 The existence of white coating was easily diagnosed by magnifying or conventional endoscopy with indigocarmine contrast method. Inspite of disappearance of white coating, E1 stage showed early ulcer recurrence (Table 5) and incomplete epithelization histologically (Table 6).

 Magnifying endoscopic diagnosis of gastric ulcer healing was made at E2 (radiating pattern) and E3 (granular pattern). Furtheremore, E4 stage which showed the fine patterns same as surroudings was considered as the complete ulcer healing.

 These fine regenerative patterns were considerably diagnosed by dying and close-up observation using conventional endoscopes in routine examination.
