Upper GI Series (Barium X-ray)

Procedure Overview

Upper GI Series (Barium X-ray) at Gangnam Heartscan Healthcare Center is a non-invasive contrast radiographic study of the upper gastrointestinal tract, covering the esophagus, stomach, and duodenum. By coating the mucosal lining with an oral barium sulfate contrast suspension and effervescent granules, real-time fluoroscopic X-ray imaging evaluates luminal contour, peristaltic motility, hiatal hernia, ulcers, and structural narrowing.

Clinical Indications

• Non-endoscopic radiographic screening of the esophagus, stomach, and duodenum
• Evaluation of swallowing difficulties (dysphagia),esophageal motility disorders, or structural strictures
• Assessment of gastric contour, hiatal hernia, ulcer craters, or mucosal irregularity
• Alternative upper GI imaging option for patients who prefer or require a non-endoscopic evaluation

How the Screening Works

1. Oral Contrast Ingestion: The patient swallows effervescent granules (to gently distend the stomach with gas) followed by liquid barium contrast medium.
2. Multi-Position Fluoroscopic Imaging: While the examination table tilts and the patient shifts positions on cue, the radiologic team captures serial X-ray images of the barium coating the upper GI tract.
3. Radiologist Interpretation: A board-certified diagnostic radiologist reviews the dynamic and static fluoroscopic images to assess mucosal architecture and motility.

Preparation & Precautions

• Fast completely from food, water, and smoking for at least 8 hours before the examination so the stomach is completely empty.
• After the examination, drink plenty of water throughout the day to help flush the barium contrast naturally from the digestive tract and prevent constipation.
• Inform the medical staff prior to the exam if you are pregnant or suspect pregnancy, or if you have a history of severe constipation or bowel obstruction.
