Overview
The name is derived from the surgeon who first described it (César Roux) and the stick-figure representation. Diagramatically, the Roux-en-Y anastomosis looks like the letter Y; typically, the two upper limbs of the Y represent (1) the proximal segment of stomach and the distal small bowel it joins with and (2) the blind end that is surgically divided off, and the lower part of the Y is formed by the distal small bowel beyond the anastomosis.
Roux-en-Ys are used in several operations and collectively called Roux operations.
