Creation of a new opening in the large intestine?

• A. Colonoscopy
• B. Costal
• C. Coronary Ischemia
• D. Colostomy

Answer: (D)

Creating a new opening in the large intestine is a colostomy. In this procedure, a portion of the colon is brought through an opening in the abdominal wall to form a stoma, allowing stool to exit into an external bag. This diverting of stool can be temporary or permanent and is done for reasons like bowel obstruction, injury, colorectal cancer requiring resection, or severe inflammatory bowel disease. Colonoscopy, by contrast, is an internal exam that visualizes the colon lining and may treat issues from inside the bowel, but it does not create an external opening. Costal relates to the ribs, and coronary ischemia refers to reduced blood flow to the heart muscle—neither involves making a new opening in the large intestine.
