Esophagram (Barium Swallow)

Fluoro+ ContrastAbdomen & Pelvisverify
Indications
  • Dysphagia
  • Odynophagia
  • Suspected stricture, web, or ring (e.g., Schatzki ring)
  • Gastroesophageal reflux / hiatal hernia
  • Suspected esophageal mass or carcinoma
  • Achalasia or other dysmotility
  • Suspected perforation or leak (use water-soluble)
  • Evaluation of varices
  • Postoperative anastomotic evaluation
Patient prep
  • NPO at least 4-6 hours (commonly NPO after midnight)
  • Remove radiopaque objects from neck/chest
  • Confirm no recent suspected perforation before giving high-density barium
  • Screen for aspiration risk and barium allergy/prior reactions
Contrast
AgentHigh-density barium sulfate suspension for double-contrast; thin (low-density) barium for full-column/motility; water-soluble iodinated (e.g., Gastrografin or low-osmolar Omnipaque) if perforation/leak suspected or aspiration risk
Routeoral
DoseVariable per swallow; effervescent granules/gas crystals for double-contrast distention
TimingReal-time fluoroscopic observation during swallowing and esophageal transit
Technique
  • Begin upright; have patient drink barium while imaging the pharynx and esophagus
  • Double-contrast: effervescent crystals then high-density barium, upright LPO/RPO for mucosal relief
  • Single/full-column: thin barium with patient prone RAO to distend and assess contour and motility
  • Mucosal relief views after column empties
  • Prone RAO bolus-swallow for primary peristalsis/motility (single swallow)
  • Provocative maneuvers for reflux/hernia: Trendelenburg, Valsalva, water-siphon test
  • Solid bolus (marshmallow, barium tablet, or bread) to unmask subtle rings/strictures

Key points
  • Use water-soluble iodinated contrast first if perforation/leak/postoperative anastomotic leak is suspected; if water-soluble is negative and suspicion persists, follow with barium for better sensitivity
  • Avoid high-osmolar water-soluble agents (Gastrografin) if aspiration risk is high (chemical pneumonitis/pulmonary edema); use low-osmolar nonionic agent instead
  • Barium is contraindicated if free peritoneal/mediastinal leak likely (barium mediastinitis/peritonitis)
  • Solid bolus challenge increases sensitivity for rings and strictures
  • Distinguish from MBSS: esophagram focuses on the esophagus; MBSS is the dynamic swallow study with speech-language pathologist
