Whatever ostomy you have, like Mooza said - You're an Ostomate!
There are many different types of ostomy. Some examples are
Ileostomy: The surgeon removes the colon and rectum and attaches the bottom of the small intestine (ileum) to the stoma. Colostomy: The surgeon removes the rectum and attaches the colon to the stoma. Urostomy: The surgeon attaches the ureters - the tubes that carry urine to the bladder - to either the small intestine or to the abdominal wall.
if you have the opening in the colon ( colostomy) or have all of the colon removed and the opening is in the "ilium" of the small bowel......
....It's the bowel that's brought out onto the abdomen, and "fashioned into the stoma", I was once told that it's folded back, much like rolling up a sleeve, and it's then sutured to the abdominal wall. The exposed stoma is actually the inside of the bowel. The area where the stoma meets the abdomen is very sensitive, and the skin may break down and bleed, but it can heal easily with the right products and care.
Understanding the structure, also helps in the care.
