Gastrointestinal (GI) obstruction is a life-threatening condition that should always be considered in the differential diagnosis of dog and cat diseases involving acute and chronic GI symptoms. Mechanical or functional obstruction leads to local circulatory obstruction, water-electrolyte abnormalities, hypovolemia and shock. Complications may include intestinal perforation, tissue necrosis, peritonitis, toxaemia and death. GI obstruction in dogs and cats is often caused by the anatomical predisposition in the intestinal structure of small animals and their constant presence in a human environment, one conducive to the swallowing of inappropriate and inedible objects (1, 2, 7, 8, 19). An early diagnosis of GI obstruction improves prognosis. Clinical symptoms of obstruction are not specific and depend on the location, degree of obstruction and developing disorders in fluid circulation. In order to make the final diagnosis, imaging methods are used: x-ray and/or ultrasound. The only effective solution is surgical or endoscopic removal of the cause of the obstruction (1, 12, 13, 19). The aim of the study is a clinical analysis of animals with GI symptoms, determination of GI obstruction frequency and evaluation of the diagnostic value of ultrasound examinations in the determination of such diagnosis.
