A surgical operation that creates a new opening or connection between the duodenum and the jejunum, allowing food to bypass a blocked or damaged section.
From duodenum plus jejunum plus -ostomy. This compound term uses two anatomical parts from the small intestine connected by the surgical suffix indicating creation of an opening.
This surgery is often performed after gastric bypass operations to reverse weight-loss surgeries or to fix complications—it's a high-skill procedure because surgeons must match the vessel sizes perfectly to prevent leaks and ensure proper food flow.
