Superficial esophageal cancer


Japanese Classification of esophageal cancer, 11th edition : Part II and III, Japan esophageal society





Superficial esophageal cancer의 내시경적 소견

• Faint hyperemia

• Change of microvasculature

• Eroded/ulcerated

• Mucosal thickening

• Coarsening of the mucosa

• Multiple white mucosal plaques

• NBI magnifying endoscopy (NBI-ME)

• Lugol’s solution apply : Lugol-voiding lesion

Biopsy

• Is, III >> IIc > IIa > IIb

• 종양의 표면에 과립상이 불규칙하게 있는 경우

• 종양의 주변부 융기가 동반된 경우

• 종양의 크기가 큰 경우

• 식도 굴곡이 많아 정확한 관찰 어려움

• 미소침윤이 있는 경우 실제보다 심달도 얕게 판단됨
