Contents
Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Fixation
Generally 10% neutral buffered formalin.
Gross processing
- Count the number of fragments. They can be classified as “multiple” at over 5 or 6 specimens. Possibly add “Mixed with luminal material”.
- Preferably stain with eosin if any fragment is smaller than about 0.3 cm
- Biopsies that are thicker than about 3-4 mm generally need to be bisected.
Microscopic examination
(Read the endoscopy report before evaluating (except for polyp biopsies, where it can be presumed that the purpose is to look for any malignancy).)
Example normal reports
Further information in main articles of each location.
(Middle third esophagus, biopsy:) Squamous mucosa without significant histopathologic changes. (Negative for eosinophilic esophagitis.) |
(GE junction, biopsy:) Squamous mucosa without significant histopathologic changes. (Negative for gastric mucosa or intestinalized (Barrett's) mucosa.) |
(Gastric, biopsy:) Gastric mucosa without significant histopathologic changes. ((Negative for Helicobacter pylori organisms on H&E slide.)) |
(Small bowel, biopsy:) Duodenal mucosa without significant histopathologic changes. ((Negative for celiac disease.)) |
(Colon, biopsy:) Colonic mucosa without significant histopathologic changes. ((Negative for colitis.)) |
