Anorectal papilloma removal

Anorectal papillomas are common in large or overweight rabbits. They are seldom neoplastic. Histologically, they are chronic inflammatory lesions presumably due to a minor rectal prolapse and chronic trauma to the mucosa. Surgery is successful in removing the proliferative tissue but does not address the underlying cause so relapse is common. Crushing the tissue with rongeurs (illustrated) before excision reduces the amount of haemorrhage.
