Final answer:
Ileostomy is the medical procedure that often results in the patient having a stoma permanently placed.
Step-by-step explanation:
The medical procedure that often results in the patient having a stoma permanently placed is called ileostomy. An ileostomy involves bringing the distal ileum through the abdominal wall and creating an opening called a stoma. This allows the watery chyme to be collected in a bag-like adhesive appliance. This procedure is typically performed when the lower part of the small intestine (ileum) or colon is damaged or removed.
