Comprehensiveness
Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Advice
- Confirm that the patient identity on the specimen container matches the identity that will be applied to the gross description and cassettes.
- Generally measure estimated volume or 3 dimensions for samples greater than 0.4 cm in greatest dimension.[notes 1]
- ((Note the color of the sample, even when unremarkable.))[notes 2]
- Generally, use inking for resection margins where cancer radicality is important.Template:Ink note Excisions made by laser do not need inking on the excision surfaces, since the coagulated surface can be easily identified in the microscope.[1]
- Black is generally the best ink for both gross identification and microscopy.
- Blue and green are great for microscopy, but are often messier to apply and can be visually difficult to distinguish from black.
- Red is most difficult to see under the microscope, and should only be used as a last resort.
- (Preferably photograph or make a drawing where slices have been taken.)[2]
- Remove any surgical stitches from samples before microtomy.
- (At least for larger samples, consider looking for medical imaging or biopsy reports in order to better guide the process.)[3]
- Generally, strive to make slices perpendicular to visible interfaces of relevant tissues.
- Generelly dissect and inspect the entire specimen, while keeping relevant parts intact enough for presentation to seniors and/or maintaining orientation.
