Diagnosis of Gastric Adenocarcinoma with Magnified Endoscopy

  • Tsuneo Oyama


Many magnified endoscopic classifications have been reported [1–5]. But a large majority of them are difficult to understand and complicated. The author divided the magnified endoscopic findings into two basic categories of surface and vascular patterns to simplify the diagnostic process [6, 7]. The theory behind this diagnostic approach with magnified endoscopy is explained in this chapter.
