RECTICULO-OMASAL AND PYLORIC STENOSIS

Functional Reticulo-omasal and Pyloric Stenosis (Vagal indigestion)

• The condition is also known as Hoflund’s syndrome or chronic indigestion or vagal indigestion or functional stenosis of the stomach.
• Clincially there are two types of functional stenosis of the stomach. These include reticulo-omasal stenosis or cranial functional stenosis and pyloric stenosis or caudal functional stenosis. Usually animals suffer from either of them and rare cases suffer from both.

Aetiology

• Both these conditions are characterized by impairment of the passage of food either through reticulo-omasal orifice or across pylorus.

Clinical signs

• The loss of body condition is rapid and the animal becomes dull and listless. Mild abdominal pain or discomfort exhibited by shifting weight from one leg to another.
• The faeces is scanty and consistency varies from normal to diarrhoetic or constipated.
• Rumen movements are sluggish and weak. The temperature, pulse and respiration rate are usually normal and dehydration occurs only in the last stages of the disease.
