| − | ==Aetiology==
| + | Impaction of the stomach typically consists ofexcessive dry, fibrous ingesta, but may also be composed of ingested materialsthat form a mass, such as persimmon seeds or mesquite beans.1-3 Otherfeeds that tend to swell after ingestion, including wheat, barley, and sugarbeet pulp, may also cause impaction. Additional signs may include dysphagia,dropping of feed, and bruxism.3,5 However, the diagnosis of stomachimpaction is usually made at surgery on horses that have had uncontrollablecolic or poor response to medical therapy. However, endoscopy will revealgastric impaction, and may provide information on the specific nature of theimpaction. Although this would not typically be performed on an acute coliccase, it would be indicated in a horse with chronic colic. |
| − | Ingestion of coarse roughage (straw bedding, poor quality forage), foreign objects (rubber fencing) and feed that may swell after ingestion or improper mastication (sugar beet pulp) have been implicated (151-154) but a specific cause is not always apparent. Predisposing factors:
| |
| − | *Poor dentition
| |
| − | *Poor mastication
| |
| − | *Rapid consumption of feedstuffs
| |
| − | *Inadequate water consumption
| |
| − | | |
| − | ==Clinical Signs==
| |
| − | Acute or chronic colic signs
| |
| − | *Anorexia
| |
| − | *Weight loss
| |
| − | *Spontaneous reflux in severe cases with gastric contents visible at the nares

| − | ==Diagnosis==
| |
| − | Often made at exploratory celiotomy if horse suffers from acute severe abdominal pain
| |
| − | Endoscopy: full stomach after a normally adequate fast (18-24hrs)
| |
| − | Abdominal radiography in smaller horses and ponies
| |
| − | | |
| − | ==Treatment==
| |
| − | Analgesia
| |
| − | Gastric lavage via nasogastric intubation
| |
| − | Massage and injection of fluid to soften the imapction at surgery(151-3)
