What is a Roux limb?
The Roux limb, the middle portion of the small intestine also known as the jejunum, is connected to the pouch. Food flows directly from the pouch into the Roux limb, bypassing most of the stomach.
What does Roux mean in surgery?
Overview. Gastric bypass, also called Roux-en-Y (roo-en-wy) gastric bypass, is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine.

How long is the Roux limb in gastric bypass?
This systematic review concludes that a range of 100-200 cm for combined length of biliopancreatic or alimentary limb gives optimum results with Roux-en-Y gastric bypass in most patients.
What is the Roux limb made of?
In this laparoscopic operation, the stomach is stapled or divided to form a small pouch (typically <30 mL in volume), which is anastomosed to the Roux limb (also known as the efferent or alimentary limb) made of jejunum of varying length (typically 75-150 cm).
What happens after Roux-en-Y surgery?
Bleeding, infection, and blood clots in your legs are possible side effects that may occur after any surgery. General anesthesia may also cause breathing problems or other reactions. You may also have leaks from the stomach pouch or the Roux limb.
How long should a Roux limb be?
The standard Roux length (sRYGB) group has a Roux limb length of 45–100 cm, with a distance from the ligament of Treitz to the jejunojejunostomy of 20–50 cm. The extended length (eRYGB) group has a Roux limb of 150 cm, with the distance of the ligament of Treitz to the jejunojejunostomy spanning 100 cm (Fig.

Standard Roux-en-Y gastric bypass (RYGB) has been used to treat these patients, with unsatisfactory results [3]. Long limb RYGB has been used to treat morbid obese and super-obese patients and has resulted in greater weight loss and a greater resolution of co-morbidities, with acceptable morbidity [4].
What is Roux-en-Y Hepaticojejunostomy?
What is hepaticojejunostomy? A hepaticojejunostomy, or Roux-en-Y procedure, bypasses the bile duct to allow digestive juices to drain from the liver directly into the small intestine. The hepatic duct is the tubular channel that carries bile from the liver to the small intestine to aid digestion.
