Endoscopic ultrasonography (EUS) was performed in 8 patients with non-Hodgikin Lymphoma of the stomach and its clinical significance was evaluated. I used Kajiyama's classification of EUS echo level. Namely, level 0 denotes an absent echo. Level 1 represents an echoic level of the 4th layer of the stomach, Level 2 the level of the splenic parenchyma. Level 3 the level between level 2 and 4. Level 4 that of the 3rd layer of the stomach. Most of the gastric lesion tended to show a lower echoic pattern or level 1, but some showed a higher echo level 2. EUS showed three types of infiltration. 1) In four cases the infiltration was confined to the 2nd or 3rd layer. 2) In three cases EUS showed transmural infiltration. 3) In one cases it showed infiltration to the surrounding organ. In four cases extragastric lymphnodes were also well demonsterated as low echoic and neary circlular masses. In two cases gastrectomy was performed and in two other cases autopsy was performed. The depth and type of infiltration evaluated by EUS corresponded well to the histological findings of the specimen. We administered chemotherapy to 7 patients and in two cases the therapy was effective, EUS clearly showed diminution of the size of the leision and the echo level increased from level 1 to 3. EUS provided a helpful information not only on the intramural extension of malignant lymphoma of the stomach but also on the effectiveness of chemotherapy.
