胃癌に対する内視鏡的粘膜切除術

抄録

For 6 years, since 1988 to 1994, we have been performed medical treatment of the 143 gastric lesions, which were diagnosed of early gastric cancer or adenoma, by the endoscopic mucosal resection (EMR) .
Method : We have performed the EMR by the Tada's method. We have peformed the EMR by two panendoscopes before 1992, but after 1992, by one 2-channels therapeuetic scopes.
Results : (1)In this study, 60 gastric cancer lesions were examined, in which 42 lesions were already diagnosed as gastric cancer before EMR. Diagnosis of 11 lesions, which were 12% of adenoma, were corrected to the early gastric cancer after EMR. On the 7 lesions, which were suspected of gastric cancer, final diagnosed of the early gastric cancer by EMR. 48/60 lesions (80%) were intramucosal cancer.
(2)By the 2 panendoscopes method, pathological complete resection rate and no recurrence rate were 63%, 85%. Simularly, by the 2-channels therapeutic scope, there were 60%, 96%. In the two EMR methods, there was no significant difference. There were 6 recurrenced cases, all these cases were occured in the pathological incomplete resected cases. Only one complication was post EMR bleeding case.
In conclusion, EMR is effective and safety method for early gastric cancer.
