    ABSTRACT: Diagnosis of the depth of the cancer invasion is necessary to select the indication of endoscopic treatment. We used endoscopic ultrasonography (EUS) and Submucosography (SMG) to diagnose the depth of cancer invasion and compared their efficacy against 63 lesions in 60 cases of gastric and esophageal cancers. SMG could diagnose the invasion correctly in 97% of m (mucosa) cancers, 88% of sm (submucosa) cancers and 100% of advanced cancers. On the other hand, linear-type EUS could diagnose the cancer invasion correctly in 60% of the m cancers, 83% of the sm cancers and 100% of advanced cancers. The results of the comparison of radial-type EUS and SMG showed similar results. Both EUS and SMG are appropriate for the judgement of endoscopic treatments. However, for the selection of the indication of endoscopic treatment which is applied to relatively small sized lesions in general, SMG appears to be superior to EUS in both resolution power and accuracy in shooting.

    ABSTRACT: Histopathological classification of gastric aberrant pancreas has been done by Heinrich's criteria. However in some case it was difficult to detect incomplete Langerhans' island consisting of several endocrine cells or a single endocrine cell by usual H-E staining. To identify the distribution of incomplete Langerhans' islands and endocrine cells, we applied an enzyme antibody method utilizing PAP method for 7 cases of gastric aberrant pancreas. It became easy to identify the endocrine cells such as single cell and islet cells by using the PAP method. In all 3 cases of aberrant pancreas classified as Heinrich type II and one of 2 case of type III, Langerhans' islands or endocrine small cell groups and single cells were found. The PAP staining method was useful to determine the Heinrich's classification of the aberrant pancreas.
