A simple method for correcting rectal prolapse in pigs.

The affected pig should be restrained and the corrugated tube gently inserted into the lumen of the prolapsed rectum the halfway-point on the tube needs to be inserted as far as the anal sphincter. The rubber bands should be stretched over the prolapse and placed as near as possible to the perianal skin; they must be tight enough to stop the blood supply to the prolapse. Faeces may move down the tube but in most instances the faeces block the tube; this presents no problem because the necrotic prolapse drops off in five to seven days, taking the corrugated tube with it (Fig 1). The pig then passes faeces normally.
