Abstract     Aim. The aim of our study was the evaluation of the TNM stage according to endoscopic ultrasonography (EUS) examination in gastric cancer patients before gastrectomy, in comparison to stage according to patho-histological examination of the resected specimen. Patients and methods. The study includes 82 patients, operated for resectable gastric cancer in the period from January 1, 2001 and July l, 2003 at the Department of abdominal and general surgery in General hospital Maribor. Determination of EUS stage has been performed preoperatively, and the patho-histological stage of the resected specimen postoperatively. Results. The comparison of EUZ and patho-histological stage revealed the accuracy of EUS stage in 68% of patients for loco-regional tumor infiltration. The accuracy of EUS stage was 68% for T1, 69% for T2, 69% for T3 and 60% for T4. Lymph nodes (N) were correctly staged by EUS in 57%. EUZ stage was accurate for non metastatic lymph nodes (N-) in 40% and for metastatic lymph nodes in (N+) 90%. Conclusions. According to our results, the accuracy of EUS stage in comparison to patho-histological stage with regard to tumor infiltration and to lymph node stage is 68% and 57% respectively. Underestimation of the final T2 and T3 stage in Tl stage by EUS, according to the results of our study, yet presents the problem of consequence of the EUS in our institution in terms of possible endoscopic ablative procedures in treatment of early gastric cancer. The present level of accuracy of EUS alows us the strategy that patients, classified preoperatively as T1 to T3, can be operated primarily with sufficient security. In patients where radical resection of the tumor seems doubtful, as in T4, N+ and presence of ascites, we recommend a diagnostic laparoscopy to confirm the diagnosis.
