In the horse, treatment is usually conservative as most obstructions resolve spontaneously or with medical treatment. Treatment comprises passage of a nasogastric tube followed by intraluminal oesophageal lavage. Before attempting this procedure it is important to ensure that the horse is well sedated (with its head below the thoracic inlet) so that the risk of aspiration is minimised. The administration of oxytocin may be beneficial, particularly in animals with cranial onstructions. If conservative treatment fails to resolve the problem, surgery to remove the obstruction may be required. Careful consideration should be given before embarking such treatment due to the high complication rate associated with oesophageal surgery.

In cattle, rumenal bloat caused by the obstruction is an emergency and requires immediate treatment. This is achieved by trocharisation through the left paralumbar fossa. Once the bloat has been relieved, the obstruction may be manually broken down via percutaneous massage, or may resolve spontaneously due to the large volume of saliva present. As in the horse, a sedative such as xylazine may be administered combined to provide both sedation and muscle relaxation. Broad spectrum antibiotics should be administered if there is any suspicion of aspiration,
