65 years old female was referred due to an EGC (biopsy: moderately differentiated adenocarcinoma). It was a small non-atrophic area in the GC side of the proximal antrum. In the close-up image, it was a small flat elevated lesion with slight depression in the center.
ESD was done as usual.

6. Depth of invasion : invades mucosa (muscularis mucosa) (pT1a)
7. Resection margin : free from carcinoma(N), safety margin : distal 10 mm, proximal 8 mm, anterior 10 mm, posterior 12 mm, deep 500 ㎛
8. Lymphatic invasion : not identified(N)
9. Venous invasion : not identified(N)
10. Perineural invasion : not identified(N)

[우리말 註]
가까이 본다고 잘 보이는 것은 아닙니다. 멀리서 위축된 점막을 고루 관찰하며 non-atrophic area가 없는지 살피면 작은 위암을 발견할 수 있습니다.
