The Capabilities of Ultrasound Diagnosis in Assessment of Gastric Carcinoma of Different Localization and Stage

Abstract

Objective: To evaluate the diagnostic possibilities of transabdominal ultrasonography for various localizations of gastric carcinoma (GC). Materials and Methods: The study included 101 patient with GC, the stage T1 in 5, the stage of T2 – in 12, the stage of T3 – in 39 and the stage of T4 – in 45 cases respectively. The stomach tumor in 37 (36.6%) cases was localized mainly in the antrum, 35 (34.6%) – in the body, 12 (11.9%) in the cardia and fundus, in 13 (12.9%) cases it had a total, in 4 (4.0%) - subtotal character. Ulcerating infiltrating forms (UIF) of GC was diagnosed in 71 cases, diffuse infiltrating forms (DIF) in 23 cases. All patients underwent preoperative X-ray, virtual gastroscopy techniques, multidetector computed tomography and transabdominal ultrasonography (USG). Results: The intestinal histological form of GC was detected in 7 cases – with USG in 6 cases. The UIF of GC with the help of USG was diagnosed in 69 (97,2%) cases, DIF – in 23 (100%) cases of T2-T4 stages. The results of USG and CT was coincided in all cases of T3 and in 92,7% of T4 stages of GC. Conclusions: The combined use of ultrasonography and gastroscopy will increase the detection of early intestinal type of GC. USG is the best, cheap, independent method for diagnosing a diffusely infiltrative form of GC, especially of the antrum. At stage T3, he is not inferior to CT in assessing the localization and prevalence of GC, and at stage T4, the difference between them is negligible.
