Malignancy
NO
The aim of this study is to confirm that the resected tumor specimen is putted the specimen board correctly and no measurement error among endosocpists.

Diagnosis
Maneuver |
5 endoscopists among 7 endoscopists except for 2 endoscopists who performed ESD were randomized and selected 3 endoscopists using sealed envelope method. Endoscopist1 put the resected specimen one by one, and measured maximum tumor size and maximum vertical size of the specimen. After putting it out from the specimen board, next endoscopist do the same procedures and recorded the sizes.
Endoscopist2 put the resected specimen one by one, and measured maximum tumor size and maximum vertical size of the specimen. After putting it out from the specimen board, next endoscopist do the same procedures and recorded the sizes.
Endoscopist3 put the resected specimen one by one, and measured maximum tumor size and maximum vertical size of the specimen.Endoscopist 3give pathologists this specimen 3 and are true size of resected specimen.
