Endoscopic resection for residual lesion of metastatic gastric cancer: A case report

Figure 1 Objective image findings at the first visit to our institute. A: EGD findings before treatment. EGD found a protruding lesion, 20 mm in diameter, at the gastric cardia; B: Abdominal CT with contrast before treatment; CT showed multiple mass lesions throughout the liver (arrows). EGD: Esophagogastroduodenoscopy; CT: Computed tomography.

Figure 2 Objective image findings after chemotherapy. A: EGD finding after chemotherapy. The lesion became unclear. It appeared smooth and protruded, and looked like a submucosal tumor; B: Abdominal CT with contrast after chemotherapy showed multiple lesions had disappeared and no evidence of disease in the liver. EGD: Esophagogastroduodenoscopy; CT: Computed tomography.

Figure 3 Result of gastric submucosal dissection. A: Macroscopic findings from a resected specimen; B: Histopathological result of a resected specimen: 28 mm × 12 mm, U, type 0-IIc, 1.0 mm × 1.0 mm, well-differentiated tubular adenocarcinoma (tub1), ypT1b, ly0, v0, pHM(-), and pVM(-).
