Overview
Barium esophagography is helpful in the diagnosis of esophageal stricture. Findings on a barium esophagogram suggestive of benign esophageal stricture include concentric narrowing, smoothly tapering and eccentric narrowing, abrupt, asymmetric in malignant causes.
Other Imaging Findings
Benign strictures can be distinguished from malignant strictures based on barium esophagography:[1][2]
- Benign:concentric narrowing, smoothly tapering,
- Malignant: eccentric narrowing, abrupt, asymmetric ,
Barium esophagography is helpful in the diagnosis esophageal stricture. Findings on a barium esophagography suggestive of esophageal stricture include:
| Barium swallowing finding | |
|---|---|
| Gastroesophageal Reflux Disease |
|
| Esophageal carcinoma | Irregular contour and shelflike proximal and distal margins |
| Scleroderma | Tapered narrowing in long segment of the distal esophagus |
| Nasogastric intubation | Long segment of narrowing in the distal esophagus |
| Radiation stricture | Smooth, tapered segment of concentric narrowing |
| Drug-induced stricture | Asymmetric focal narrowing in the upper thoracic esophagus |
| Esophageal sclerotherapy | Long, irregular stricture in the distal esophagus |
| Caustic ingestion | Segmental or diffuse strictures |
- Endoscopic ultrasound is used for detection local invasion in malignant causes
- Esophagogastroduodenoscopy (EGD) is done for staging suspicious malignant causes that were diagnosed in barium esophagogram
- Ct scan is used for staging malignant strictures
- Manometry is used in cases of esophageal stricture due to dysmotility
- Chest radiography can be used for diagnosis extrinsic compression as a cause of esophageal stricture
