Complex endoscopic examination in differential diagnosis of various macroscopical forms of lymphomas and cancer of stomach

Abstract

   Now there is a problem of timely diagnostics of malignant lymphoms as a result of expressed polymorphism of the visual picture frequently accepted for a cancer and other stomach diseases.
   Study objective. Increase of diagnostic efficacy of lymphomas and carcinoma of stomach using endosonographic method.
   Methods. The work was based on examination and treatment data of 29 patients with various macroscopical types of lymphoma and carcinoma of the stomach. To all patients intracavitary scanning and tumor biopsy was carried out after a video gastroscopy.
   Results. After visual examination in 8 (27.6%) observations we could not diagnose with full reliance a stomach lymphoma. Endosonography in 3 (10.3 %) cases signs of stomach lymphoma with typical thickening of submucosal layer was revealed. At 3 (10.3 %) patients were detected ultrasonic characteristics of infiltrative cancer, were visualised the hypoechogenic homogeneous mass which is starting with a mucosa, infiltrate submucosal and muscular layers that the differentiation of these layers has been completely disturbed. Only in 2 (6.9 %) cases among all patients we could not detail the diagnosis. Thus, endosonographic examination in 6 (20.7 %) patients of this group has specified the visual diagnosis, and in 21 (72.4 %) patient — has confirmed. Results was statistically significant (p < 0.05). Diagnostic value analysis of visual and endosonographic method in lymphoma revealing has shown significant superiority of the last. Its sensitivity 12 % over than visual endoscopic method, diagnostic accuracy — on 6.8 % above.
