Gastrointestinal obstruction is a life-threatening condition that is usually caused by accidental ingestion of inedible objects, through play or food indiscretions. Ingested foreign objects generate the mechanical obstruction of the gastrointestinal segment, characterized by a relatively typical set of symptoms, depending on the location. The aim of this study was the clinical and imaging description of some cases of gastrointestinal obstruction in dogs and cats, caused by swallowing textile foreign bodies. The study included 12 dogs and 8 cats of different breeds and ages, belonging to both sexes, which showed clinical signs suggestive from a clinical-anamnestic point of view for gastrointestinal obstruction. These patients had symptoms with acute or chronic progressive evolution of the gastrointestinal tract, including restlessness, deviation, vomiting (single or repeated episodes), abdominal tenderness, constipation and tenesmus. The diagnosis was confirmed by radiographic examination, simple and with contrast medium, and ultrasound, completed in some situations with laparotomy. Ingested textile foreign bodies were represented by socks/stockings (5 dogs and 3 cats), underwear (3 dogs), rope (1 dog and 3 cats), carpet fragments (2 dog and 1 cat), toy fragments (1 dog and 1 cat), and they were located in the stomach (7/12; 58.33%, respectively 4/8; 50%), in the gastro-duodenal segment (2/12; 16.67%, respectively 3/8; 37.5%), in the jejunum (3/12; 25%, respectively 1/8; 12.5%) and in the colon (1/12; 8.33%, respectively 1/8; 12.5%). Gastrointestinal obstruction in pets, caused by accidental ingestion of textile foreign bodies, is a medical emergency and imaging examinations are the main diagnostic tool in the establishment of a subsequent therapy with maximum efficiency.
