Surgical management of rectal prolapse in an Indian rhinoceros (Rhinoceros unicornis)

An acute rectal mucosal prolapse in a 26-yr-old Indian rhinoceros (Rhinoceros unicornis) was repaired surgically by mucosal resection. Two days postoperatively, suture line dehiscence accompanied by substantial hemorrhage was managed by ligation and hemostasis during a second immobilization. Medical management with nonsteroidal anti-inflammatory drugs and diuretics reduced the mucosal edema and prevented recurrence of the prolapse. A combination of butorphanol and detomidine provided excellent reversible chemical restraint for this animal.
