 The resected specimens of colorectal T1 cancer are appropriately treated to obtain an accurate pathological diagnosis. Immediately after the lesion excision, the lesion is attached to the specimen fixing board using a pin. Then, it is fixed with 10% neutral buffered formalin solution. Then, the surface structure of all excised specimens is observed in detail under a stereomicroscope. An endoscopist makes incisions so that the area of interest is a pathological specimen. Thereafter, the resected specimen is submitted to the pathology department.

 Proper handling of resected specimens is one of the important processes that facilitate accurate diagnosis. It is the responsibility of the endoscopist to submit the specimen in a state where detailed examination is possible.
