There were 1623 cases of initial gastric ulcer, 113 cases of recurrent. ulcer, 29 cases of second recurrent ulcer and 44 cases of relapsing ulcer in past six years (from 1967 to 1973). Their classification and stage in 77 cases comparing with pathological finding after operation are investigated and illustated as follows: 1) Stages of gastric ulcer in operated cases are pathologically classified with four stages: active, intermediate, healing and scar. Comparing, with endoscopic classification 79.7% of operated cases are consistent with endoscopic stage. 2) Fibrinoid degeneration are disclosed in active stage (++), and intermediate stage (++)-(-). No fibrinoid degeneration is found in healing and scar stage. Those are useful to decide the healing stage of ulcer. 3) Gastric ulcer with acute bleeding is belong A I or A II in endoscopic classification and its lacking in the fibrinoid degeneration so it showed be considered as an acute ulcer. Clinically, it is important to comf irm the existence of f ibrinoid degeneration by biopsy. 4) Incidence of the six stages of gastric ulcer: AI 8.4%, AII 28.3%, HI 11.8%, HII 10.9%, HIII 8.9%, S31.3%. 66.7% of total cases of gastric ulcer located inangle and lower body. Location of ulcers showes a tendency of the high percentage in gastric body and it is parallel with ages especially in female. 5) Incidence of the stage of recurrent in active stage within one year is 31.1% but over one year is 59.2%, second recurrent within one year 38.9%, over one year 63.6 %, relapsing within one year 65.9 % and over one year 54.5%.
