What is duodenojejunostomy?

Duodenojejunostomy is a surgical procedure that involves creating an anastomosis, or connection, between the duodenum (the first part of the small intestine) and the jejunum (the second part of the small intestine). This operation is typically performed to bypass a blockage or to facilitate the passage of food and digestive juices when normal flow is impeded, such as in cases of certain tumors or congenital conditions. It can also be part of surgeries for weight loss or to treat complications from other gastrointestinal conditions.
