  • Title: Pylorectomy and gastroduodenostomy in the dog: technique and clinical results in 28 cases.
    Author: Walter MC, Matthiesen DT, Stone EA.
    Journal: J Am Vet Med Assoc; 1985 Nov 01; 187(9):909-14. PubMed ID: 4055513.
    Abstract:
    Pylorectomy and end-to-end gastroduodenostomy are surgical procedures that allow excision of abnormal pyloric tissue and provide improved gastric outflow. These techniques were used for the treatment of benign, malignant, and ulcerative conditions that were judged to be not adequately treatable with pyloromyotomies or pyloroplasties. End-to-end gastroduodenostomy was not much more difficult than a standard intestinal anastomosis; however, a thorough knowledge of the pyloric area anatomy was required to avoid serious surgical errors. In addition, gentle tissue manipulation and precise suture placement reduced the chance of iatrogenic pancreatitis, biliary obstruction, tissue ischemia, and/or suture line leakage. The results of surgery depended on the underlying disease process. Dogs with benign lesions such as chronic hypertrophic pyloric gastropathy responded favorably to treatment. Dogs with malignant disease and perforated ulcers had low long-term survival rate. Pyloric adenocarcinoma was not adequately treated with this method alone.
