Small Bowel, Excision During Gastric Bypass:
	- Small bowel wall with increased intraepithelial lymphocytes, otherwise within normal limits, see comment.

Small Bowel, Excision during Obesity Surgery:
	- Small bowel wall with increased intraepithelial lymphocytes, otherwise within normal limits, see comment.

Comment:

Immunostains show that the lymphocytes are predominantly T cells (CD3 >> CD20).

The significance of the increased intraepithelial lymphocytes (IELs) is unknown. Causes of IELs (infection, inflammatory bowel disease, celiac disease) should be considered clinically.
