Why a stoma may be fashioned?

If you mean a surgically created opening to the urinary bladder or to the intestines, or for a tracheostomy, they are open. e.g. A stoma IS always open. A temporary stoma may be made and later closed, but by definition, stoma is an "opening".1. Picture of trach stoma. - This shows a trach stoma cap which protects the stoma.2. Picture of a loop ileostomy. -- Whether the stoma opens to bowel or bladder, the outside of the stoma appears basically the same. If for bladder, a small flexible tube is kept put through the stoma; a see-through "bag" attached to the skin (or upper thigh) collects the urine which the person must dump. The tubing is replaced periodically. If for bowel, a see through pouch is affixed onto the skin, over the stoma, to collect feces. The feces must be 'dumped' also.On any stoma, the area must be cleansed or the tender tissue can break down, bleed, become infected, etc.
