 The Japan Esophageal Association has established a new simple classification for superficial esophageal squamous cell carcinoma in order to diagnose the depth of invasion of tumors. The classification is based on the presence of loop formation and thick abnormal vessels and includes the following categories : B1, presence of a loop-like shape ; B2, absence of a loop-like shape ; and B3, presence of very thick(60μm or thicker)vessels. This study describes the effectiveness and limitations of this new classification.
