  • Title: Repurposing medical devices as "button" esophagostomy tubes for extended nutritional support.
    Author: Craven MD.
    Journal: J Vet Intern Med; 2022 Jan; 36(1):196-203. PubMed ID: 34786762.
    Abstract:
    BACKGROUND: Esophagostomy tubes (E-tubes) are widely utilized for extended nutritional support in dogs and cats. Problems associated with their use include the unwieldy excess (10-20 cm) of external tubing, constant need for neck wraps and necessity for skin sutures, suture tract infection, and tube loss if sutures fail. OBJECTIVES: To evaluate 2 different, low profile (LP) "button" products intended for use in people as enteral (jejunostomy [J] and gastrojejunostomy [G-J]) feeding tubes for suitability as LP E-tubes in dogs and cats. ANIMALS: A young giant breed dog that required extended (>6 months) nutritional and fluid support during recovery from severe neurological illness with protracted adipsia, anorexia, and dysphagia. METHODS: Prospective evaluation of 2 commercially available LP feeding devices after placement of a standard E-tube. An LP J-tube and an LP G-J tube were assessed in consecutive 4-week trials, for tube retention, patient comfort, stoma health, and functionality. RESULTS: Both products performed extremely and equally well as LP E-tubes in this clinical patient, enhancing patient freedom and comfort by eliminating external tubing, skin sutures, and bandaging. The dual port G-J tube allows medication delivery (eg, sucralfate) to the entire esophagus, but for safety alone (ie, to avoid aspiration), the single port J-tube appears the best device for client-owned patients. CONCLUSIONS AND CLINICAL IMPORTANCE: The LP enteral feeding tubes from the human medical field can be successfully used as LP E-tubes in dogs and cats, offering superior patient comfort, with no obvious detriment to the patient and main drawback of higher cost.
