What is gastroduodenostomy into its component word parts?

Gastroduodenostomy can be broken down into three component parts: "gastro-" meaning stomach, "duodeno-" referring to the duodenum (the first part of the small intestine), and "-stomy," which denotes a surgical creation of an opening. Therefore, gastroduodenostomy refers to a surgical procedure that creates a connection between the stomach and the duodenum.
