Description
A pedunculated lipoma is a common cause of small intestinal strangulation or obstruction in horses older than fifteen years of age. It is seen in all types of horses but most commonly in ponies and cob-type horses. Geldings appear to be at higher risk compared to mares and stallions.
Lipomas are the most-common intra-abdominal tumour of geriatric horses. They are often multiple in number and attach to the mesentery of the intestine via a stalk or pedicle of varying length. The stalk becomes wrapped around a segment of small intestine, causing compression of the intestinal lumen and corresponding mesenteric vessels. More rarely, broad-based tumours can occur causing periodic restriction of ingesta without intestinal compromise. Lipomas may also be incidental findings at post mortem or exploratory laparotomy.
Clinical signs
- Acute onset abdominal pain (flank-watching, rolling, kicking, pawing)
- Decreased borborygmi
Other clinical findings include the production of large volumes of gastric reflux following nasogastric intubation, although this may be absent in the early stages of disease. Multiple distended loops of small intestine may be palpable on rectal examination or visible on ultrasonographic examination.
Treatment
Prognosis
The prognosis for this condition depends heavily on the time between diagnosis and surgery. If surgery is performed relatively early on, a
