The sensitivity, specificity, and predictive value of these imaging signs as predictors of gastric wall necrosis, as determined by visual inspection at surgery or necropsy, were determined. The sensitivity and specificity of gastric pneumatosis were 14.1% and 92.7%, respectively. The prevalence of gastric wall necrosis was 26.6%. The positive and negative predictive values of gastric pneumatosis for predicting gastric necrosis were 40.9% and 74.9%, respectively. Gastric pneumatosis and pneumoperitoneum were identified together in four dogs. Pneumoperitoneum, either alone or in conjunction with pneumatosis, yielded similar results as a test for gastric necrosis. Splenomegaly and severity of gastric distention were insensitive and nonspecific for gastric wall necrosis. Splenomegaly did not predict the need for splenectomy at surgery. Although pneumatosis and pneumoperitoneum are relatively specific signs of gastric wall necrosis, the utility of these signs as a test for gastric necrosis is limited in clinical practice. The significance of pneumatosis should be taken into consideration with previous treatments for gastric decompression, as percutaneous gastric trocharization or orogastric intubation may increase the number of false\u2010positive results.<\/jats:p>","DOI":"10.1111\/j.1740-8261.2004.04034.x","type":"journal-article","created":{"date-parts":[[2004,5,25]],"date-time":"2004-05-25T18:24:42Z","timestamp":1085509482000},"page":"205-209","source":"Crossref","is-referenced-by-count":30,"title":["Pneumatosis in Canine Gastric Dilatation\u2010Volvulus Syndrome"],"prefix":"10.1111","volume":"45","author":[{"given":"Anthony J.","family":"Fischetti","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.
