esophageal perforationGI disease A defect in the esophagus where the lumen communicates with the thoracic cavity
of or pertaining to the esophagus.
very rare; include atresia, duplication, segmental aplasia, esophagorespiratory fistulae, diverticula, epithelial inclusion cysts.
congenital lack of continuity of the esophagus, commonly accompanied by tracheoesophageal fistula, and characterized by accumulations of mucus in the nasopharynx, gagging, vomiting when fed, cyanosis and dyspnea. Treatment is by surgical repair by esophageal anastomosis and division of the fistula.
may result from acute or chronic obstruction of the esophagus, or from defective innervation. See also megaesophagus.
may be tubular and communicate with the effective esophagus, or cystic appearing as a cystic mass close to the functioning esophagus.
clinically visible enlargement as seen in esophageal diverticulum, stenosis, paralysis, cardial obstruction.
a cause of acquired megaesophagus; usually caused by trauma or spontaneous ulceration.
see reticular groove.
esophageal groove lesion
includes granuloma, papilloma, foreign body lodgment; cause of obstructive bloat.
hyperkeratotic thickening of the esophageal mucosa due usually to hypovitaminosis A or chlorinated naphthalene poisoning.
esophageal motility disorders
very rare except for papilloma and fibropapilloma; causes chronic esophageal obstruction.
acute obstruction is manifested by inability to swallow, regurgitation of saliva, food and water through the nose and much discomfort expressed by retching movements and pawing at the throat. Ruminants develop ruminal tympany. Chronic obstruction shows the same syndrome but with a gradual development and a tendency to develop aspiration pneumonia.
occurs in dogs in association with the parasite Spirocerca lupi.
a cause of obstructive bloat.
causes esophageal obstruction.
see patch graft.
causes local cellulitis and compression-obstruction of esophagus.
esophageal pulsion diverticulum
a diverticulum that pushes outwards causing pressure on surrounding organs and tissues.
esophageal segmental aplasia
causes esophageal obstruction in neonates.
esophageal stenosis, esophageal stricture
causes esophageal obstruction; may be partial, permitting passage of liquids.
see nasogastric tube.
usually associated with pressure necrosis due to prolonged obstruction and injury by a solid foreign body or, rarely equine dysautonomia or Gasterophilus spp. infestation.
distended veins at the gastric cardia causing dysphagia.
a hole or break in the containing walls or membranes of an organ or structure of the body. Perforation occurs when erosion, infection or other factors create a weak spot in the organ and internal pressure causes a rupture. It also may result from a deep penetrating wound caused by trauma.
usually the result of obstructive urolithiasis with eventual leakage of urine into the peritoneal cavity. See also congenital urinary bladder rupture.
occurs when an infectious process erodes the tympanic membrane or leads to increased pressure in the middle ear.
causes local cellulitis and obstruction of the esophagus.
a complication of duodenal and gastric ulcers. It requires immediate surgical correction to prevent hemorrhage, shock and peritonitis.
is usually a result of obstructive urolithiasis; urine collects in a ventral subcutaneous site.
