Gastric Torsion: A Horribly Unhealthy Kind of Twist

Thursday, July 1st, 2010
Torsion, gastric torsion, gastric dilatation-volvulus, GDV; these are terms you never want to hear applied to your dog.  They all mean the exact same thing- your dog’s stomach is distended with gas and has twisted on itself, and emergency surgery offers the only hope for saving his life.  Here’s a visual aid to help you understand what happens when a dog develops gastric torsion.  Picture a fanny pack in your mind.   The pouch of the fanny pack represents your dog’s stomach.  One strap of the fanny pack is the esophagus that transports food from your dog’s mouth down into his stomach.  The other strap is the upper small intestine (duodenum) that transports food out of the stomach.  Now hold one strap of the fanny pack in each hand and twirl the pouch until it twists on itself causing the straps to crimp.  This is what happens when gastric torsion occurs- the stomach twists on itself, cutting off normal blood flow to the stomach and surrounding structures.  Additionally, gas and fluid continue to accumulate within the stomach and cannot flow out via the crimped esophagus or duodenum, so the stomach progressively distends. A dog in this situation quickly lapses into a state of shock and surgical “decompression” or untwisting of the stomach is the only way out of this nightmare.  Time is of the essence- the longer the stomach remains twisted, the greater the likelihood of irreversible devitalization (death) of the stomach tissue.

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.

Morris Animal Foundation 2010 K9 Cancer Walk

Wednesday, April 14th, 2010

I am gearing up for Morris Animal Foundation’s 2nd annual K9 Cancer Walk to be held in Elk Grove, California (www.curecaninecancer.org/) on Saturday, April 24th.  Just as was the case last year, I will be a speaker at this fabulous event along with Dr. Michael Kent, a staff oncologist at the UC Davis veterinary school.  The actual walk will begin at 10:00 am and the speakers program will be at 11:30 am.

Care to join me there?  If you cannot participate in person, I hope you will consider joining my virtual Speaking for Spot Team (http://maf.convio.net/site/TR/Events/CCC?team_id=1260&pg=team&fr_id=1040).   And if you are able to attend, please come introduce yourself to me.  I would love to meet you!

Here is the blog I posted one year ago after the very first K9 Cancer Walk.

Walking to Cure Canine Cancer

This past Saturday, I saw four three-legged dogs- each one having lost a limb as part of their treatment for bone cancer.  I met another sweetie pie with a shaved patch over one side of his chest.  His mom told me this was the site where her pup’s chest cavity was drained of fluid produced by a cancer growing at the base of his heart.  Yet another dog I encountered had an orange-sized tumor on the bridge of his nose. 

Believe it or not, I met none of these dogs in a veterinary hospital setting; rather, we were all gathered in Elk Grove, California, the site of the very first Morris Animal Foundation Walk to Cure Canine Cancer. Morris Animal Foundation has launched an unprecedented $30 million fundraising effort with the following goals in mind:

1.  Provide new treatments for dogs currently suffering from cancer
2.  Establish a high-quality tumor sample bank that can be used by cancer researchers
3.  Develop prevention strategies so that cancer might one day be eliminated or, at the very least, drastically reduced in incidence and severity
4.  Train new researchers who will work towards discovering preventions, treatments and cures

An important part of the fundraising effort will be in the form of “Walks to Cure Canine Cancer.”  The Elk Grove Walk raised $17,945!  I had the honor of speaking at this fabulous first-of-its-kind event-what a thrill to be part of it all!  More than 300 dogs and their humans gathered together in the fight against canine cancer.

As unfathomable as it sounds, cancer will be the cause of death in one out of every four of our beloved canine companions.  There’s so much we don’t yet know about what causes canine cancer and how best to treat it.  I’m thrilled with the Morris Animal Foundation plans.  They are an incredibly ethical and effective organization, and I am expecting great things. To learn more about the Morris Animal Canine Cancer Campaign, please visit www.curecaninecancer.org/. I encourage you to participate in any way you can.

Best wishes to you and your four-legged family members for abundant good health,

What is a Veterinary Specialist?

Sunday, March 21st, 2010

I participate in a list serve for veterinarians who specialize in internal medicine. The list serve “topic de jour” concerns veterinarians who are general practitioners (also known as family veterinarians), yet bill themselves as “specialists” in specific venues such as surgery, dentistry, or cardiology.  The responses have been strongly disapproving, and here is the reason why:  The American Veterinary Medical Association dictates that the term “specialist” be reserved only for veterinarians who have completed all of the requirements to become a “diplomate” within a specialty organization. What must a veterinarian do to become an official specialist/diplomate? Trust me, it is a long and arduous process! After graduating from veterinary school, wannabee specialists must complete a minimum three-year internship and residency training program, author publications in peer reviewed journals, and pass some insanely rigorous examinations specific to the specialty they are pursuing.  (Note that the requirements differ for those who become specialists in complementary/alternative medicine fields of veterinary medicine such as homeopathy, acupuncture, chiropractic, and Chinese herbs.) If one is successful in completing this rigorous and extensive training they achieve “board certification” status and are deemed to be “specialists” or “diplomates” within their chosen specialty.  This is much like the process physicians go through to become specialists.

The world of veterinary specialists has grown by leaps and bounds.  Much like Starbucks®, if there’s not already a group of specialists in your community, there likely will be soon!  Veterinary specialists are found in university teaching hospitals and in some private practices.  They often “cohabitate,” sharing specialty staffing, equipment and laboratory services with specialists in different areas of expertise.  When this is the case, you, the lucky client, end up with access to multiple specialists under one roof.  Not only is this convenient, it also focuses a lot of brainpower and experience on your pet- group discussions about patients (medical rounds) typically occur daily in such specialty hospital settings.

When might you need the services of a veterinary specialist? Just as your family physician refers patients to specialists, your family veterinarian should be considering referral in the following three situations:

  1. A second opinion is desired by you or your veterinarian.  Yes, you definitely have the right to request a second opinion.  I know it can be tough telling your vet you would like a second opinion, but as your beloved pet’s medical advocate, you are obligated to do so just as soon a your “gut” starts suggesting that a second opinion makes sense. I encourage you to read the chapter called, “A Second Opinion is Always Okay” in Speaking for Spot- it will provide you with plenty of helpful coaching about how to tactfully broach the subject with your veterinarian! Hopefully your vet has established relationships with local specialists- the kind she would trust to take good care of her own dog should the need arise. Not all family veterinarians are keen on “letting go” of their patients, so self-referral might be your only way to seek out the help of a specialist.
  2. Help is needed to figure out what is wrong with your pet. Specialists have advanced diagnostic tools (ultrasound, endoscopy, CT imaging, MRI scans, etc.) and have developed the skills to use them. Additionally, because of their extensive experience with challenging cases, specialists often have the ability to hone in on a diagnosis in the most direct and expedient manner.
  3. Your vet doesn’t specialize in the disease your pet has or the therapy he needs.  Just as with our own health issues, treatment is ideally managed by someone who works with that particular disease issue day in, and day out, and regularly pursues continuing education pertaining to that disease.

How can you tell if a particular veterinarian is truly a specialist?  Simply examine the initials following his or her name. See the list of specialties and their corresponding initials below. For example, if you look at the initials following my signature (ACVIM), you can tell that I am a specialist in The American College of Veterinary Internal Medicine. To learn more about any of these areas of specialization, pay a visit to the websites.  Those listed below are within the United States, but you will find comparable organizations in many other countries or continents.

Have you ever taken your pet to a veterinary specialist?  Have you ever wanted to do so, but had trouble getting “buy in” from your family veterinarian?  If so, please share your experience.  I’d love to hear from you.
