To investigate certain types of inflammation, during a colonoscopy, a doctor might pinch off normal-looking mucosa at a number of locations for subsequent microscopic examination. What is the size of each specimen, e.g., dimensions, volume?
For example, one would think that specimen size would be discussed in the ASGE 2013 Guideline for Endoscopic mucosal tissue sampling, but it isn't. Orientation is, number of sites is, but specimen size is not.
My question is about biopsy of normal mucosa, not polyps or other visible abnormalities. A reference for this information would be appreciated as well.
