Gastric Torsion: A Horribly Unhealthy Kind of Twist
Initial symptoms of gastric torsion include a bloated appearance through the midsection (the ribs look like they are expanding outward), drooling, nonproductive retching/vomiting, restlessness, weakness, shallow breathing, rapid heart rate (if it can be felt through the chest wall), and pale gum color. If you observe such symptoms, quickly make some phone calls to find the closest veterinary hospital capable of performing immediate surgery on your best friend. The sooner surgery can be performed the greater the likelihood of a successful outcome. Irreparable damage to the stomach tissue is often the deal breaker if the torsion is not corrected quickly. At the time of surgery, not only is the stomach derotated, it is tacked (attached with stitches) to the inside of the abdominal wall to prevent a repeat spinning performance. Additionally if the spleen or portions of the stomach wall appear devitalized (deprived of normal blood flow for too long) they will be removed. If surgery is successful, the dog typically has a minimum two to three day post-operative stay in the hospital for round the clock monitoring for post-operative complications.
Truth be told, we really don’t know much about what causes gastric torsion. Clearly, there is a breed/conformation association- large deep-chested breeds such as Great Danes, Irish Setters, Standard Poodles, Irish Wolfhounds, Boxers, Dobermans, Weimaraners, and Rottweilers are particularly predisposed. Affected males definitely outnumber females. One study documented that elevating the food bowl actually predisposes to gastric torsion. Other studies have indicated that the following factors may also be part of the recipe that results in gastric dilatation-volvulus: eating only one meal per day, eating rapidly, eating dry foods that list oils or fats among the first four label ingredients, exercising in close association to mealtime, being underweight, and being of an “anxious” rather than “happy” personality type. The only known way to prevent gastric torsion from occurring is by performing a prophylactic (preventive) gastropexy procedure (sutures are used to tack the stomach wall to the inside lining of the abdominal cavity). This does not prevent the bloating (stomach distending with gas), but does prevent the life threatening twisting part of this miserable disease process.
Would you like to participate in a study to learn more about why dogs develop gastric torsion? If your dog has ever bloated (distention of the stomach without rotation) or has experienced gastric torsion, I encourage you to take this survey http://www.surveymonkey.com/s/WS2VKFP. It is being conducted by Dr. Cynthia Otto from the University of Pennsylvania School of Veterinary Medicine in collaboration with researcher, author and lecturer, Dr. Carmen Battaglia. A summary of the results and findings will be posted at www.breedingbetterdogs.com in November, 2010. If you and your dog did have direct experience with a gastric torsion, I sure as heck hope yours was a happy ending.
