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. | |||
