Which procedure involves creating an opening from the ileum to the abdominal wall?

The procedure that involves creating an opening from the ileum to the abdominal wall is known as an ileostomy. This surgical procedure is performed to allow waste to exit the body directly from the ileum, which is the last part of the small intestine, when the lower part of the digestive tract is not functioning properly.

In an ileostomy, the ileum is brought through the abdominal wall and secured in place to form a stoma, which is the opening where waste is collected in an external bag. This is often necessary for patients who have undergone surgeries for conditions such as inflammatory bowel disease, colorectal cancer, or severe trauma to the intestines.

The other options do not pertain to creating an opening from the ileum to the abdominal wall. Immunology focuses on the immune system and its functions rather than surgical procedures. The intraperitoneal method refers to processes within the peritoneal cavity, often relating to dialysis or delivery of medications, but it does not involve forming a stoma. Lastly, the inguinal procedure typically relates to surgeries in the groin area, such as hernia repairs, and is not associated with an ileostomy.
