This week’s case is a 5-month-old male Labrador Retriever with vomiting for 24 hours. Painful on abdominal palpation. What is your interpretation?
On radiographs of the abdomen, there is distension of several small intestinal loops with gas. The distended loops are arranged in a loosely plicated fashion. There are normal bowel loops located in the ventral portion of the abdomen. These loops while normal in size, contain granular mineral and soft tissue material. The stomach contains soft tissue material and gas bubbles. There is soft tissue material in the pylorus on the left lateral projection (image 2). The liver, spleen, and urinary tract are normal.
Focal small intestinal dilation with plication indicates a mechanical small intestinal obstruction by a linear foreign body. There is foreign material located in the stomach which is likely anchored in the pylorus.
A gastrotomy and enterotomy were performed, and soft fabric and string were removed from the stomach and string from the plicated small intestine.
