Small bowel biopsy
Key points
- Small bowel biopsy is a diagnostic procedure in which a portion of the lining of the small intestine is removed for examination.
- Small bowel biopsy samples can be obtained by EGD (esophagogastroduodenoscopy) or other endoscopy of the upper gastrointestinal tract.
- Preparation for this test is similar to that for an EGD.
- The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust.

Definition
Small bowel biopsy is a diagnostic procedure in which a portion of the lining of the small intestine is removed for examination.
How the test is performed
Small bowel biopsy samples can be obtained by EGD (esophagogastroduodenoscopy) or other endoscopy of the upper gastrointestinal tract. A flexible tube (endoscope) is inserted through your mouth or nose and into the upper gastrointestinal tract. Tissue samples removed during endoscopy are sent to the laboratory for examination.
How to prepare for the test
Preparation for this test is similar to that for an EGD. Fasting for at least 4 hours is recommended. You must sign an consent form.
Infants and children:
The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For general information regarding how you can prepare your child, see the following topics:
- Infant test or procedure preparation (birth to 1 year)
- Toddler test or procedure preparation (1 to 3 years)
- Preschooler test or procedure preparation (3 to 6 years)
- Schoolage test or procedure preparation (6 to 12 years)
- Adolescent test or procedure preparation (12 to 18 years)
How the test will feel
The passage of the tube and capsule often makes a person feel like gagging (topical anesthetic is used to minimize this sensation).
A mild sedative can be given, but only in small doses because the person must remain alert enough to assist with the procedure (by doing such things as swallowing and turning). The biopsy sampling causes little or no pain, although it may cause some mild cramping.
Why the test is performed
This test is most often performed to help diagnose diseases of the small intestines.
Normal Values
Normal small bowel tissue includes finger-like projections (villi), crypts, columnar epithelial cells, and round cells.
What abnormal results mean
Abnormal findings may include:
- Ulcers
- Polyps
