Fluoroscopic examination was quite helpful for making an accurate diagnosis, selecting a proper treatment, including indication for surgery, and judging a prognosis in each cases.
Characteristic fluoroscopic findings in the forestomach diseases were impaction and bloat of the rumen, atony, slow and weak contraction and foreign bodies in the reticulum, atony of the abomasum, and functional disorders of the colon. In 80% of the cows with these diseases, the reticulum had sharp foreign bodies. As the tips of these bodies touched the mucosae of the reticulum, reticular contraction became unclear or less marked. These bodies might act as triggers for functional disorders of the reticulum and other parts of the forestomach, finally causing reticular and abomasal atony.
In 92% of the cows with abomasal displacement, the reticulum had sharp foreign bodies and showed the same movements as described above. These findings suggested that abomasal displacement might have some relations with such functional disorders in the fbrestomach as caused by traumatic reticulitis.
