"subacute stage: 10-20 days after ingestion and characterised by oesophageal ulceration"
"chronic stage: occurs after 21 days with oesophageal inflammation healed by fibrosis resulting in stricture"
Expected headings
"Fluoroscopy"
"Complications"
"acute stage: in the first 10 days from ingestion; acute necrosis with mucosal blurring and dilated atonic oesophagus"
"Water-soluble contrast medium is preferred in the acute stage. Findings in acute stage include mucosal oedema, ulceration and sloughing of the mucosa with oesophageal dilatation and atony. Complications seen in this stage can include perforation and leakage; the same findings can be seen in the subacute stage with mild oesophageal narrowing."
"Barium contrast can be used in the chronic stage; single long or multiple strictures involve the middle and lower oesophagus."
