Aetiology

When a diseased or affected portion of the intestine is removed, the remaining sections of the intestine are surgically connected back together.

This surgical connection is called an anastomosis, and there are several types:

  • Colon-rectal
  • Colon-anus
  • J-pouch

As a result, the rectal reservoir decreases in size and increases the likelihood of stool incontinence.1
