Sa290 Gastrointestinal Foreign Body Obstruction in Dogs

Overview GI obstructions are a common cause of vomiting in patients seen in clinical practice. Causes of anatomic obstruction include foreign bodies (linear or nonlinear), pyloroantral hypertrophic disease, polyps, intussusception, intramural masses (neoplasia, granulomatous enteritis, phycomycosis, satrictures, hematoma), and extramural compression (adhesions, strangulation, volvulus). Functional obstruction is caused by such disorders as adynamic ileus (e.g., surgical operations, peritonitis, sepsis, metabolic abnormalities). Intestinal obstruction can be classified as acute or chronic, partial or complete, and simple or strangulated.
