74 years old female was referred for the treatment of gastric cancer (histology: moderately differentiated adenocarcinoma). Would you try ESD or refer to the surgeon?

ESD was done.

ESD : Early gastric carcinoma
1. Location : low body, posterior wall
2. Gross type : EGC type IIc
3. Histologic type : tubular adenocarcinoma, moderately differentiated
4. Histologic type by Lauren : intestinal
5. Size of carcinoma : (1) longest diameter, 15 mm (2) vertical diameter, 12 mm
6. Depth of invasion : invades submucosa, (depth of sm invasion : 200 ㎛) (pT1b)
7. Resection margin : free from carcinoma(N), safety margin : distal 15 mm, proximal 6 mm, anterior 14 mm, posterior 18 mm, deep 300 ㎛
8. Lymphatic invasion : not identified(N)
9. Venous invasion : not identified(N)
10. Perineural invasion : not identified(N)
11. Microscopic ulcer : absent
12. Histologic heterogeneity: absent

I carefully discuss the risk of recurrence, and the patient made an informed choice for the careful observation without surgery.
