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.
