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.[1]

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.


  1. Patient drinks radio-opaque contrast, most often barium
  2. 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
