A surgical procedure that creates a direct connection between the stomach and another part of the digestive tract (usually the small intestine), bypassing damaged sections.
From Greek 'gaster' (stomach) + 'anastomosis' (a connecting opening). This surgical term emerged in the late 19th century as gastric surgery developed.
Gastroanastomosis sounds complex, but it's basically plumbing—surgeons reroute the digestive system like fixing a clogged pipe, and this surgery can actually help some people with obesity by reducing how much food enters the small intestine!
