Multiplicity of early gastric cancer is a well-known. Sometimes, another cancer is found in the first follow-up endoscopy after a successful ESD for EGC. Of course, the patient is not happy. The doctor is unhappy, too.

ESD was done as usual for the second cancer. The procedure was difficult due to the location. A big loop approach was used.


ESD: Early gastric carcinoma
1. Location : body
2. Gross type : EGC type IIa
3. Histologic type : tubular adenocarcinoma, well differentiated
4. Histologic type by Lauren : intestinal
5. Size of carcinoma : (1) longest diameter, 16 mm (2) vertical diameter, 10 mm
6. Depth of invasion : invades mucosa (lamina propria) (pT1a)
7. Resection margin : free from carcinoma(N), safety margin : distal 12 mm, proximal 10 mm, anterior 14 mm, posterior 6 mm, deep 400 §­
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

When another cancer was found after ESD within a year, we call it a synchronous cancer.
