👉 Duodenoscopy is a surgical procedure that involves removing the lining of the large intestine from the right side of the small intestine. This procedure is often performed to diagnose and treat conditions such as Crohn's disease, inflammatory bowel diseases, and diverticulitis. It is also used to monitor the healing process after surgery on the stomach or colon. Duodenoscopy is typically done under local anesthesia and requires general anesthesia for more complex procedures.
