Gastric dilatation-volvulus (GDV) is a common medical and surgical emergency that involves severe gas distention and malposition of the stomach in dogs. GDV results in profound distension of the stomach which compresses vital blood vessels and organs within the abdomen, thus reducing oxygen delivery to these organs. The ultimate result is tissue death and toxins in the blood stream. Surgery is necessary to correct the condition, and overall mortality rates range from 10-50% depending on severity and duration of gastric dilatation. For this reason, rapid and effective decompression of the stomach is critical for successful treatment of dogs with GDV. Currently, approaches to decompression have a temporary effect and gas can re-inflate the stomach within minutes. Oftentimes affected dogs are not near a facility with surgical capabilities when they develop signs of GDV. Owners may then need to drive hours to a facility in which emergency stabilization and surgery can be performed. In this study, a new, minimally-invasive technique, similar to that used in human medicine, will be tested for its ability to immediately and continuously alleviate the gas distention in the stomach of GDV patients using a specialized catheter, thus allowing the patient to be stabilized and/or transported for surgery. This relatively inexpensive and rapid procedure could have far-reaching impact for dogs with this devastating condition.
