Intestinal atresia in calves: 22 cases (1978-1988).

A retrospective study of 22 calves afflicted with intestinal atresia was performed to determine typical signs of disease, treatment, and survival rate. All 22 calves, except 2 heifers with atresia ani and rectovaginal fistula, were examined when they were between 1 and 10 days old because of depression, anorexia, abdominal distention, and lack of feces. All calves had been observed to stand and suckle shortly after birth. Survival rate was influenced by the atretic segment affected: 0% (0/2 surgically treated) for atresia jejunal; 42% (5/12 examined) or 71% (5/7 recovering from general anesthesia) for atresia coli; and 63% (5/8 examined) or 71% (5/7 surgically treated) for atresia ani. Survival appeared to depend principally on early recognition, anatomic site affected, and successful surgical establishment of a patent intestinal tract.
