Abstract

Gastric dilatation-volvulus (GDV) is a common and catastrophic disease of large and giant-breed dogs. Treatment of GDV includes medical stabilization followed by prompt surgical repositioning of the stomach in its normal anatomic position. To prevent reoccurrence, gastropexy is used to securely adhere the stomach to the body wall. Effective gastropexy decreases the recurrence of GDV from as high as 80% to less than 5%. The purpose of this article is to describe the history, indications, and techniques for gastropexy. Gastropexy was first reported in veterinary medicine in 1971 for the management of gastric reflux, and later in 1979 for treating and preventing the recurrence of GDV. Gastropexy is indicated in all dogs that undergo surgical correction of GDV. Additionally, prophylactic gastropexy should be strongly considered at the time of surgery in dogs undergoing splenectomy for splenic torsion and potentially other splenic pathology, and in dogs of at-risk breeds, such as Great Danes, that are undergoing exploratory celiotomy for any reason owing to evidence for increased risk of GDV in these patients. Although there are numerous techniques described, gastropexy is always performed on the right side of the abdomen, near the last rib. Ensuring an anatomically correct gastropexy location is vital to prevent postoperative complications such as partial pyloric outflow obstruction. Gastropexy can be performed as part of an open surgical approach to the abdomen or using a minimally invasive technique. When combined with surgical correction of GDV, gastropexy is almost always performed as an open procedure. The stomach is repositioned, the abdomen explored, and then a permanent gastropexy is performed. Techniques used for open gastropexy include incisional, belt-loop, circumcostal, and incorporating gastropexy, as well as gastrocolopexy. Each of these has been described later. Incisional gastropexy is currently the most commonly performed method of surgical gastropexy in dogs; it is quick, relatively easy, safe, and effective. Minimally invasive techniques for gastropexy are often used when gastropexy is performed as an elective, isolated procedure. Minimally invasive techniques include the grid approach, endoscopically guided miniapproach, and laparoscopic gastropexy. Laparoscopic gastropexy is the least invasive alternative; however, it requires special equipment and significant surgical expertise to perform. The authors consider it a veterinarian׳s responsibility to educate the owners of at-risk large and giant dog breeds about prophylactic gastropexy given such a favorable risk-benefit profile.
