'''Predisposing factors are any that cause tenesmus or diarrhoea''', such as enteritis, colitis, parasitism, dystocia, obesity, urethral obstruction or cystitis/urolithiasis, '''respiratory disease causing prolonged coughing and also increased abdominal fill''' in high fecundity ewes or cases of [[Bloat|bloat]].

'''Clinical examination''' is usually sufficient to diagnose and stage a rectal prolapse.

A prolapse must be '''differentiated from an ileocolic intususception''' by passing a proble, blunt instrument or finger between the prolapsed mass and the rectal wall. The fornix of the rectal wall in a prolapse would prevent insertion beyond a couple of centimetres.

==Treatment==

An '''epidural''' should be administered and the '''prolapse cleaned with warm water and soap''' and then '''evaluated for viability and necrosis'''. Any necrotic areas should be '''surgically debrided/amputated''' using the appropriate procedure and wounds sutured closed. It should then be '''replaced manually with plenty of lubricant'''. Circumferential '''purse string sutures''' can be placed to prevent recurrence although care must be taken not to occlude faecal passage. These are removed in 3-4 days.
