A patient with EGC was referred (pathology report: P/D adenocarcinoma). Based on the pathology report and unclear border of the lesion, initial plan was surgery. However, outside slide review and repeated biopsy at my hospital was all M/D adenocarcinoma.

55 year old male

After a long and careful discussion, the patient and I decided to do ESD.

ESD was done as usualy and the final pathology was excellent.
