Roux en y Gastric bypass

Roux en y bypass is a procedure done as bariatric surgery used to treat morbid obesity  or after gastrectomy done for gastric cancer!  the Roux-en-Y anastomosis looks like the letter Y; typically, the two upper limbs of the Y represent a proximal segment of small bowel and the distal small bowel it joins with (which is often a blind end), and the lower part of the Y the distal small bowel (beyond the anastomosis).
