What is a stoma?

The term "stoma" is used in medicine for an artificial bowel outlet, an artificial urinary diversion or a permanent tracheostomy.

There is a big variety of various forms of a stoma. Basically, a distinction is made between Ileostomy (small intestine), colostomy (colon) and urostomy (bladder).

On the sketch on the right side, you can see an ileostomy, on which I focused on.

The output drains out of the body into a device called "ostomy pouch".
