A small-bowel follow-through, also called small-bowel series, is a radiologic examination of the small intestine from the distal duodenum/duodenojejunal junction to the ileocecal valve.
An X-ray examination of the most proximal small bowel (duodenum) is typically done together with an examination of the esophagus and stomach and is called an upper GI series.
- Person drinks radio-opaque contrast.
- X-ray images of abdomen are made at timed intervals.
Pathology of the small bowel is uncommon. Therefore, upper GI and lower GI endoscopy is often done prior to small-bowel follow-through.
Categorically, the indications are:
- Negative upper endoscopy and negative lower endoscopy
- Investigation of a small bowel abnormality found on other medical imaging
