Lower-intestinal contrast studies (i.e., barium enema) have been reported to have 100% sensitivity and 100% specificity for identifying mechanical obstruction (meconium impaction, atresia coli) of the transverse colon or small colon in foals less than 30 days of age ( Figure 11-14) . The only published study on 20 foals less than two weeks of age with acute abdominal pain reported that an exploratory celiotomy revealed functional ileus (45%), meconium impaction (25%), large-colon displacement (15%), small intestine displaced around the base of the cecum (10%), ruptured gastric ulcer, and small colon obstructed by the ovarian ligament. 8 These reports underscore the difficulty in definitively identifying the cause of abdominal pain prior to exploratory celiotomy in neonatal foals, as clearly some of these cases, such as enteritis and functional ileus, would not be considered to be predominantly surgical diseases.	./cache/cord-022483-hdmwv540.txt	./txt/cord-022483-hdmwv540.txt
