👉 Gastroduodenotomy is a surgical procedure performed to remove part of the small intestine or duodenum (the lower part of the digestive tract) from the stomach. It's called this because it involves cutting open the stomach and removing the portion that goes down into the small intestine through an incision in the abdomen. This operation can be used to treat various conditions, such as diverticulitis (a blockage of the digestive tract), inflammatory bowel disease, or certain types of cancer.
