Presentations and targets
Gross processing
More specific grossing is available for presentations above. For larger specimens (not biopsies):
- Identify segment of intestine if possible.
- Measure length, average width and any significant variations thereof.
- Optionally, measure the mesentery.
- Inspect the serosa- look for any perforations, adhesions, fistulas and exudate.
- If perforation is present, try to probe it from the serosal surface
- Open longitudinally
- If the specimen is not fixed already, put it in formalin, preferably for a total of 48 hours.[1]
- Look for for any mucosal lesions. Note any evidence of inflammation, hemorrhage, abscess, perforation or fistula.
- Note the thickness of the wall.
- Note any obvious mesenterial lymph nodes. A more comprehensive search for lymph nodes is necessary in cases of Intestine with tumor.
- Sections to submit for microscopy:
- 2 sections of any perforation(s), any mucosal lesions, any obvious lymph nodes.
