Overview
Esophageal fluoroscopy is most sensitive within the first 24 hours. Small bowel follow through is inferior to CT of the abdomen and pelvis with oral contrast for detection and localization of small bowel perforation.
Gastrointestinal perforation other imaging finding
Fluoroscopy
- Esophageal fluoroscopy is most sensitive within the first 24 hours.[1]
- 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.[2]
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.[3]
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.[4]
