Overview
Fluoroscopy
- Most sensitive within the first 24 hours.
- A water-soluble agent should be used initially as barium can cause mediastinitis and can produce granulomas.
- Esophageal perforation may be represented as mucosal irregularity or gross extraluminal contrast extravasation.
- Dye studies may be useful for evaluating patients with a pleural effusion and a thoracotomy tube who are suspected to have an esophageal leak.
Suspected gastroduodenal perforation
- An upper GI study with water-soluble contrast medium is not usually the primary study for detection of a suspected gastric or duodenal perforation but can be useful for confirmation of an equivocal appearance on CT or for detection of the precise location of a small perforation.
Suspected small bowel perforation
- Small bowel follow through is inferior to CT of the abdomen and pelvis with oral contrast for detection and localization of small bowel perforation.
