Focal and linear gastrointestinal obstructions in dogs and cats are commonly seen and often require emergency surgical intervention in conjunction with attentive medical management. This chapter focuses on focal and linear gastrointestinal obstruction due to foreign body ingestion as well as intussusception. Gastrointestinal obstruction causes many local and systemic abnormalities that contribute to the development of the clinical signs observed. Abdominal radiography is frequently used to assess the abdomen in vomiting patients. The type of surgery performed is dependent on the extent of injury to the intestine. A careful and thorough inspection of the entire gastrointestinal tract should be performed. Gastric foreign bodies are removed through a longitudinal gastrotomy incision on the ventral surface of the stomach. Animals with evidence of perforation or significant intestinal injury and necrosis should be treated with resection and anastomosis that allows removal of the compromised section of intestine.
