Presentations
Gross processing
More specific grossing is available for presentations above.
- Identify segment of colon
- Measure length and variations in width
- 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
- Semi-quantitate the number of diverticula – “numerous” if too many to count
- Look for for any mucosal lesions. Note any evidence of inflammation, hemorrhage, abscess, perforation or fistula
- Note the thickness of the wall
- Optionally, measure the mesentery
- Note any obvious mesenterial lymph nodes
- Sections to submit for microscopy:
- 2 sections of any perforation(s), one section of intact diverticulum, any mucosal lesions, any obvious lymph nodes.
- If there is no perforation: 3 sections of diverticulum.
