Gastropexy with an automatic stapling instrument for the treatment of gastric dilatation and volvulus in 20 dogs.

Abstract

Surgical stapling equipment was used to create a gastropexy in 20 dogs undergoing emergency surgery for gastric dilatation and volvulus (GDV). The technique involved creation of a tunnel between the seromuscular layer and the submucosa of the pyloric antrum, and a matching tunnel beneath the right m. transversus abdominis. The arms of a gastrointestinal anastomosis stapling device were introduced into the tunnels, and the device was fired to create the gastropexy. One dog died of systemic sequelae of GDV during the early postoperative period. None of the remaining 19 dogs developed a recurrence of GDV during follow-up periods ranging from 5 to 43 months. In 11 dogs, the integrity of the gastropexy was evaluated by abdominal ultrasonography and either negative contrast gastrography or double contrast gastrography; in these dogs, the radiographic and/or the ultrasonographic findings were suggestive of an intact gastropexy. There were no complications involving the gastropexy staple line. The results of this study indicate that an effective and consistent permanent gastropexy can be created, using surgical stapling equipment.
