Surgery of the neonatal bovine digestive tract.

Many disorders of the calf's gastrointestinal tract require surgical intervention if a successful outcome is to be obtained. The most common abnormalities in this category are abomasal volvulus, abomasal ulcers, small intestinal accidents, and atresia of the spiral colon. These can be differentiated by the age of the animal at presentation and a careful physical examination. Special considerations in neonatal gastrointestinal surgery include: ensuring adequate serum immunoglobulin status, rapid treatment of dehydration and hypoglycemia, and consideration of the inheritability of any corrected defects. Prompt attention to metabolic disturbances and correction of the abnormalities are essential for a successful outcome.
