👉 A duodenotomy is a surgical procedure that involves removing part of the small intestine from the duodenum, which is located at the end of the large intestine (colon). This surgery can be used to treat conditions such as ulcers or bleeding in the colon. It is often performed on patients who have had other procedures such as appendicitis or a perforated appendix removed. The procedure usually takes about 30 minutes and involves general anesthesia, followed by sedation and recovery.
