Abstract

An adult, male, Dorper sheep with a history of regurgitation and postprandial chronic tympanism underwent imaging examinations. In the simple radiographic examination of the cervical and thoracic region were observed a ventral deviation of the trachea and presence of gas in the area of ​​projection of the thoracic esophagus. The barium sulphate esophagogram revealed contrast retention and moderate dilatation of the portion of the esophagus between the fourth and ninth thoracic vertebrae. In the endoscopic evaluation, the diagnosis of segmental megaesophagus was confirmed, as the thoracic portion of the esophagus was distended, fluid and food accumulation and hypomotility were present in the affected area, without any alteration of the mucosa or sign of stenosis
