Normal Fluoroscopic Appearance of the Pediatric Gastrointestinal Tract | Pediatric Radiology Reference Article | Pediatric Imaging

Etiology:
Imaging Radiograph:
— Colonic air-fluid levels are common during bowel clean out
— In chronically dilated bowel it is difficult to distinguish small bowel from colon
Imaging Fluroscopy:
— Esophagus has a smooth contour without extrinsic compressions and the primary peristaltic wave should flow continuously through the esophagus without interruption, if flow of peristaltic wave is interrupted then consideration should be given to the presence of proximal escape of primary peristalsis
— Stomach should have a normal contour and should have the lesser curvature above the greater curvature and should empty briskly
— Dudodenal bulb should distend nicely and the duodenum should have a normal contour and the duodenal jejunal junction (ligament of Treitz) should be at the level of the duodenal bulb and over the left pedicle of the spine or to the left of the spine
— Jejunum (on the left side of the abdomen) has a feathery appearance and compared to the ileum (on the right side of the abdomen) the jejunum has a greater caliber and has thicker and more numerous folds
— Colon should have a normal contour and the haustra should be well visualzied
Imaging CT:
— Jejunum normally enhances more than ileum due to increased number of valvulae conniventes in jejunum
