Roux limb

Roux limb may be formed in multiple different gastrointestinal surgeries, including

In these surgeries the small bowel is divided at some point. This leaves two components of small bowel:

The end of the distal component is dragged up and connected (anastomosed) to the remnant stomach (or oesophagus in the case of total gastrectomy). This is the Roux limb. It accepts incoming food and transmits it from the gastric remnant to the colon. It is sometimes referred to as the "feeding limb" (to differentiate it from the "biliopancreatic limb"). The term "efferent" limb is also sometimes used, but this term may be more appropriate in the setting of a Billroth II gastrojejunostomy configuration.

History and etymology

The Roux limb is named after César Roux (1857-1934).
