Abilities of Transabdominal Ultrasonography in the Diagnosis of Gastric and Duodenal Leiomyomas
The purpose of this study was the identification of abilities of transabdominal ultrasonography of leiomyomas of stomach and duodenum. Material and methods. The study is based on the materials of clinic, endoscopy and ultrasonography of 34 patients, undergoing treatment in the hospital since 2002 to 2007. There were 9 men and 25 women. A stomach was filled with 500-800 ml of water. Results. Nonepithelial lesions of stomach and duodenum were identified in all cases. The leiomyomas were more common than any other nonepithelial lesion (24 cases) that was confirmed by operation. In the present observation all leiomyomas arose from muscular layer of stomach and duodenum. Criteria for diagnostic significance of ultrasonogra-phy were: sensitivity - 96.30 ± 3.6%, specificity - 98.44 ± 1.5%, accuracy - 97.80 ± 1.5%. Conclusions. Thus, transabdominal ultrasonography of upper gastrointestinal tract has a great diagnostic efficacy in identifying of nonepithelial tumors.
