Partial gastrectomy with an automatic stapling instrument for treatment of gastric necrosis secondary to gastric dilatation-volvulus.

A gastrointestinal anastomosis stapling instrument was used to perform partial gastrectomy in nine dogs undergoing emergency surgery for gastric dilatation-volvulus. The amount of necrotic stomach resected was 20% to 50%. Permanent gastropexy was performed, and six dogs also required partial or total splenectomy. Six dogs (67%) were normal after surgery, with follow-up periods of 6 to 16 months for five dogs. One dog died and two dogs were euthanatized because of postoperative complications unrelated to the surgical technique. There were no complications involving the partial gastrectomy staple line.
