  • Look Inside

 TV-Endoscopic findings were compared with those obtained by dissecting microscope and histologic examination of surgically resected stomachs. Results are as follows.

 1. Minute surface structure seen by TV-Endoscope was confirmed to correspond to those consisted of gastric pits observed by dissecting microscope.

 2. Differential diagnosis of early gastric cancer and estimation of histological type are to some degree possible endoscopically by observing whole lesion and such minute surface structure on TV-Endoscope.

 3. Dense and diverse Leistenspitz due to carcinomatous tubules is noted in well-differentiated adenocarcinoma unless surface structure is destroyed by carcinomatous erosion. Leistenspitz is most often elongated or linear in shape for elevated type and circular or rod in shape for excavated type.

 4. Poorly-differentiated adenocarcinoma has insular foci of regenerative epithelium consisting of wide Leistenspitz in excavated area and relatively large gastric foveolae remaining as a result of destruction of normal gastric mucosa.

 5. Possibility of making use of the findings of Leistenspitz in differential diagnosis was discussed by measuring the width of Leistenspitz of both carcinomatous and non-carcinomatous areas by TV-Endoscope and dissecting microscope. There were cases in which the difference in width of Leistenspitz was not significant between carcinomatous and non-carcinomatous areas. Thus, the width of Leistenspitz alone is not useful in differential diagnosis.
