===Description===

A pedunculated lipoma is a common cause of small intestinal strangulation or obstruction in horses older than fifteen years of age. Less commonly they may affect the small colon. Lipomas are seen in all types of horses but mostly in ponies and cob-type horses. Geldings appear to be at higher risk compared to mares and stallions. It is unclear whether the risk of lipoma formation is associated with body condition.

Lipomas are seen in all types of horses but mostly in ponies and cob-type horses. Geldings appear to be at higher risk compared to mares and stallions, suggesting a possible endocrine aetiology. It is unclear whether the risk of lipoma formation is associated with body condition.

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. Longer stalks are associated with more severe and complete intestinal strangulation. 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.

===Treatment===

===Treatment===

The only treatment available for the disease is surgical resection the tumour and, if necessary, any compromised intestine. The surgeon will evaluate the colour of the mesentery, the mucosa, intestinal motility and whether a pulse remains in the mesenteric vessels when deciding whether to resect and the portion of intestine to be removed.

===Prognosis===

===Prognosis===

The long term survival following surgery varies from 38% to 50%. If surgery is not performed until signs of cardiovascular compromise have occurred the prognosis is poor.  

Studies have shown that around 75% of horses that have undergone surgery will be discharged, but the long term survival following surgery varies from 38% to 50%. The prognosis is more favourable if surgery is performed before signs of cardiovascular compromise have occurred.
