The intestinal prolapse occurred as a complication of the castration in fou
r horses. Two of them were castrated using the open method without ligation
(1, 2), one using the closed method without ligation (4). All of these thr
ee horses were castrated in the field condition. One horse (3) was castrate
d using the primary closure technique at the clinic. The bilateral intestin
al prolapse in the horse castrated in its home stable (2) by the clinic sta
ff surgeons was treated using the reposition of the intestine and the closu
re of the abdominal cavity. Two horses (1,4) were treated by private practi
tioners using temporary fixation of the bowel in the scrotum. Consecutive l
aparotomy and enterectomy was performed in both of them at the clinic. Seve
re diarrhoea followed by the ileal obstruction on;he tenth day alter castra
tion appeared at one of these horses (4). The ileal obstruction was treated
surgically. The primary closure method of the castration in the further pa
tient (3) was complicated by extravaginal prolaps because of the rupture of
the peritoneum and fascia transversalis. Also this horse was treated using
laparotomy and enterectomy. All of the horses recovered and were withdrawn
from the clinic. Two of them died after six (1) and twelve (3) month after
castration respectively. One horse (2) survived for two years after castra
tion and was sold to a new owner. The last one (4) is still living live mon
ths after the castration complicated by the intestinal prolapse.
