Gastrointestinal endoscopic examination and Computed tomography. a. A gastrointestinal endoscopic examination was performed and disclosed an ulcerated lesion in the lesser curvature of the gastric corpus located at 7 cm from the esophagogastric junction, which squashed and isolated the gastric folds from the rest of the stomach. b. An elevated lesion that appeared to be a submucosal tumor (SMT), which was suspected of being an advanced gastric cancer, was detected on the anal side of the ulcerated lesion. c. Computed tomography (CT) revealed thickening of the gastric wall and findings indicative of abdominal wall invasion.
