Ileojejunal bypass
Ileojejunal Bypass
Ileojejunal bypass (pronounced: il-e-o-je-ju-nal by-pass) is a surgical procedure that is performed to treat obesity and related health conditions.
Etymology
The term "Ileojejunal bypass" is derived from the names of the two parts of the small intestine involved in the procedure: the ileum and the jejunum. The term "bypass" refers to the surgical technique of creating a pathway to avoid a certain area.
Procedure
In an ileojejunal bypass, the surgeon creates a direct connection from the ileum, the last part of the small intestine, to the jejunum, which is the middle part. This bypasses a significant portion of the small intestine, reducing the body's ability to absorb calories and nutrients from food, which can lead to weight loss.
Indications
Ileojejunal bypass is typically recommended for individuals who are severely obese and have not been able to lose weight through diet and exercise. It may also be used to treat certain health conditions related to obesity, such as type 2 diabetes or heart disease.
Risks and Complications
As with any surgical procedure, ileojejunal bypass carries some risks, including infection, bleeding, and complications from anesthesia. Long-term complications can include malnutrition due to reduced nutrient absorption, and dumping syndrome, a condition in which food moves too quickly from the stomach to the small intestine.
