Transabdominal Ultrasonography for Assessing the Depth of Tumor Invasion in Gastric Cancer

摘要

BackgroundAlthough endoscopy and endoscopic ultrasonography are generally used to diagnose the depth of gastric tumor invasion, endoscopy is invasive and frequently results in patient discomfort. Transabdominal ultrasonography (TUS) is noninvasive and may be useful in determining this depth. We investigated the usefulness of TUS in determining the depth of tumor invasion in patients with gastric cancer.
