Esophagostomy tubes are used to provide long‐term support to the patients. Esophagostomy tube can be maintained for several weeks to months. They are mostly used to support anorexic patients with chronic systemic disease. They are also used for patients with severe trauma to the head, after surgery of the oral cavity, or to keep the stomach decompressed (Crowe and Devey 1997a; Devitt and Seim 1997; Levine et al. 1997; Kanemoto et al. 2017).

Esophagostomy tubes are contraindicated for dogs or cats with esophageal disease. Megaesophagus, esophagitis, esophageal stricture, and reflux are contradictions for the placement of an esophagostomy tube. However, an esophagostomy tube has been used to keep a megaesophagus decompressed to reduce the risk of aspiration pneumonia in one dog (Kanemoto et al. 2017). Esophagostomy tubes have also been advanced to the jejunum to support dogs with pancreatitis or anorexia (Cummings and Daley 2014).

The main advantage of an esophagostomy tube is that a diet modified into a gruel can be used to support the patient. The nutrition is delivered three or four times a day. Diet is blenderized with enough water and delivered slowly and warm to the patient. Also, dogs and cats can eat orally even if the tube is in place. The tube is then used for complement if the caloric intake is not sufficient.
