- Single contrast barium swallow in supine/RAO position. There is severe dysmotility of the oesophagus and complete failure of emptying into the stomach.
- Single contrast barium swallow - now standing up. Due to gravity, barium empties into the stomach.
- Double contrast barium swallow. The upper and mid-sections of the oesophagus are patulous and again show severe dysmotility. There is smooth tapering towards the gastro-oesophageal junction. No convincing stricture. No mucosal abnormality.
LAO: with gas, the gastro-oesophageal junction dilates up to 1.5 cm.
Cardiac rosette view.
Frontal: patulous duodenum with delayed gastric/duodenal emptying.
