JEJUNOILEAL BYPASS Meaning and
Definition
-
Jejunoileal bypass is a surgical procedure that involves rerouting a portion of the small intestine. It is typically performed as a treatment for severe obesity and is designed to restrict food absorption, thereby facilitating weight loss. The procedure involves bypassing a significant length of the jejunum, the second part of the small intestine, and connecting the proximal (closer to the stomach) end of the intestine to the distal (closer to the large intestine) end of the ileum, the final part of the small intestine.
By bypassing a section of the small intestine, the jejunoileal bypass reduces the amount of surface area available for nutrient absorption and alters the normal digestive process. This leads to a decrease in caloric intake and malabsorption of nutrients, resulting in weight loss. Additionally, the bypassed section of the intestine no longer comes into contact with ingested food, thereby reducing the absorption of certain vitamins, minerals, and bile acids.
While the jejunoileal bypass was once a popular procedure, it has largely been abandoned due to significant long-term complications. These include malnutrition, kidney stones, gallstones, liver disease, electrolyte imbalances, and a higher risk of developing vitamin and mineral deficiencies. Consequently, the procedure is now rarely performed and has been largely replaced by other effective weight loss surgeries, such as gastric bypass or adjustable gastric banding.

Etymology of JEJUNOILEAL BYPASS
The word "Jejunoileal Bypass" is a medical term used to describe a surgical procedure. It can be broken down into two main components: "Jejuno-" and "ileal".
1. Jejuno-: It originates from the Latin word "jejunus", which means empty or fasting. In medical terms, the "jejunum" refers to the middle section of the small intestine, between the duodenum and the ileum.
2. -ileal: The term "-ileal" refers to the ileum, the last section of the small intestine before it enters the large intestine or colon.
Therefore, "Jejunoileal Bypass" can be understood as a surgical procedure that involves bypassing or diverting a part of the small intestine, specifically the jejunum and ileum, which are important segments for digestion and absorption of nutrients.
