Which limb is the Roux limb?

When describing the surgery, the Roux limb is the efferent or antegrade limb that serves as the primary recipient of food after the surgery, while the hepatobiliary or afferent limb that anastomoses with the biliary system serves as the recipient for biliary secretions, which then travel through the excluded small …

Why is it called a Roux limb?

The Roux limb is named after a Swiss surgeon César Roux (1857-1934), who was Chief of Surgery at the county hospital of Lausanne and following the opening of the new University of Lausanne, in 1890, was its inaugural Professor of External Pathology and Gynecology 2,3.

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).

Where does Roux-en-Y come from?

The pouch holds one to two ounces of food or liquid at a time, while the remnant produces enzymes important for digestion. The term Roux-En-Y comes from the Y connection that is made with the small intestines during the surgery. This procedure has a successful track record and has been performed for more than 20 years.

What is Roux en?

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.

Is Roux-en-Y restrictive or malabsorptive?

Roux-en-Y is the most common type of gastric bypass surgery. The procedure involves stapling the stomach to create a small pouch that holds less food. We shape a portion of the small intestine into a “Y.” Roux-en-Y is: Malabsorptive (limits food absorption)

What is Portoenterostomy?

[ pôr′tō-ĕn′tə-rŏs′tə-mē ] n. A surgical procedure for the treatment of biliary atresia in which a Roux-en-Y anastamosis is connected to the hepatic end of the divided extravascular portal structures, including the rudimentary bile ducts.

Where is the Roux limb?

The biliopancreatic limb, also known as the duodenum, is located at the beginning of the small intestine. This limb contains digestive juices from the stomach, bile and pancreas. The Roux limb, the middle portion of the small intestine also known as the jejunum, is connected to the pouch.

What happens to the jejunum in a roux en Y reconstruction?

In a Roux-en-Y reconstruction, the jejunum is transected close to the ligament of Treitz, creating two distinct segments. The distal segment is sutured to the gastric remnant (gastrojejunostomy), becoming the efferent limb.

Is the afferent limb the same as the Roux limb?

It appears that the afferent limb is the same as the roux limb (= proximal to the gastrojejunal anastomosis) and the efferent limb is distal.

How does Roux en Y gastric bypass surgery work?

Roux-en-Y gastric bypass surgery. In this operation, the stomach is stapled or divided to form a small pouch (typically <30 mL in volume), which empties into a Roux limb of the jejunum of varying length (typically 75-150 cm). There are two anastomoses: a proximal gastrojejunal anastomosis and a distal jejunojejunal anastomosis.

What’s the difference between Roux en Y and hepaticojejunostomy?

Roux-en-Y choledochojejunostomy – indications same as Roux-en-Y hepaticojejunostomy. Roux-en-Y pancreas reconstruction after blunt abdominal trauma. Roux-en-Y hepaticojejunostomy or choledochojejunostomy with gastrojejunostomy as palliation for irresectable pancreatic head cancer.
