Also know as neoplasm, it is the unchecked growth of malignant cells in surrounding tissue. Further contagion (metastasis) may occur via the lymphs or blood.


The first part of the colon or large intestine, located right after the junction between small and large intestine.

Closed End Ostomy Bag

Also called a closed ostomy bag or pouch, it is a one use bag. It has no openings to allow waste discharge so it is discarded once full. It is convenient as requires no cleaning. Other ostomy bag features.


Partial or total resection of the colon. It may lead to a colostomy or an ileostomy if the whole colon is removed. In either case an ostomy bag is needed at least until reconstruction surgery is performed.


The large intestine, the final 3-4 feet of the gastrointestinal tract.

Colon Rectal Surgery

The medical and surgical treatment of diseases of the small and large intestine, including the rectum and anus.


An orifice or ostomy, performed to allow passage through the abdominal wall and onto the skin surface of the end portion of the colon that remains connected to the gastrointestinal tract. That part of the colon is made to protrude the abdomen about 1 to 2 inches. The protrusion is called the stoma, and when the stoma is made up of colon tissue is called a colostomy. After a colostomy, body secretions go through the stoma and into a colostomy bag. If a colostomy is performed too low or if it compromises the rectum, then it cannot be reversed and the colostomy bag must be worn permanently. As an alternative to constant use of an ostomy pouch, some colostomy patients may adopt colostomy irrigation. More about colostomy.

Colostomy Irrigation

An enema performed through a colostomy to induce stool evacuation. It represents an alternative to wearing a colostomy bag. In depth information on colostomy irrigation.

Continent Ileostomy

Please see: Koch Pouch.


Surface that is curved or rounded outward (think of the yolk on a large fried egg). It stretches the peristomal skin and compresses its borders forcing more protrusion from the stoma. The role of convexity in ostomy patients.

Convex Ostomy Supplies

Convex appliances are referred to in a number of ways. The convex part of the appliance might be known as the convex flange, convex baseplate, convex barrier, convex wafer or ring. They are used to avoid leaks mainly when dealing with retracted and flush stomas. However they are also indicated for ostomates with a protruding (normal stoma), with too many creases or scars on the peristomal skin, or with weak muscles around the stoma and who experience continuous leakages. Convex ostomy appliances are gently pushed over the stoma, effectively encircling it while creating a barrier between stoma and skin. This in turn creates a seal that prevents leaks. Convex ostomy supplies are usually more expensive than flat ones, but compensate on wear time and comfort. About wearing convex ostomy supplies: When, how, which.

Crohn’s Disease

An inflammatory immune disease of the intestinal tract that causes thickening of the intestinal wall, inflammation and ulceration of the intestinal lining (mucous membrane). Crohn’s Disease can cause problems from the mouth to the anus. Symptoms include abdominal pain, diarrhea, fever, and weight loss. Complications include bleeding, obstruction, perforation and development of fistulas. The last resort for some Crohn’s Disease cases is the removal of the affected section of intestine and create an ostomy, usually an ileostomy.

Cut-to-Fit Ostomy Bag

It is a bag or pouch where the user must trim the hole with scissors. It is used on stomas that are oval, irregular, or too large. Complete information on ostomy bags.
