barium swallow study showing an abrupt tapering of the distal oesophagus at the gastro-oesophageal junction, with distal oesophageal dilatation; there was stagnation of the barium agent, indicating severe oesophageal dysmotility

Barium swallow demonstrated proximal oesophageal dilatation with delayed emptying (Figure 1).
abdomino-pelvic CT scan in axial view, showing distension of the stomach and intestines; the distended large bowel anterior to the liver displaced it medially, suggestive of a long-standing process

F2
Abdominopelvic CT scans revealed luminal dilatation of the oesophagus, stomach, small and large bowel, as well as faecal loading (Figure 2).
gastroscopy demonstrated a dilated proximal oesophagus with a distal narrowing and oesophagitis

An upper endoscopy showed proximal oesophageal dilatation with distal oesophagitis and narrowing (Figure 3).
(A, B) capsule endoscopy images revealed distal oesophagitis with ulceration (green arrows)

F4
Distal oesophagitis with ulceration was seen, and a significant amount of food was in the stomach despite overnight fasting, suggestive of gastroparesis (Figure 4(A, B)).
