Features:
- Normal small bowel wall.
Note:
- May have increased intraepithelial lymphocytes.[2]
Sign out
Small Bowel, Excision During Gastric Bypass:
- Small bowel wall within normal limits.
Small Bowel, Excision during Roux-en-Y Gastric Bypass: - Small bowel wall within normal limits.
IELs present
Small Bowel, Excision during Gastric Bypass: - Small bowel wall with increased intraepithelial lymphocytes, otherwise within normal limits, see comment. Comment: The increased intraepithelial lymphocytes are likely explained by obesity; however, other causes (such as infection, inflammatory bowel disease and celiac disease) should be considered within the clinical context.
