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	Sacculations Fixed transverse folds Esophageal intramural pseudodiverticula
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
