Roux-en-Y anastomosis
From Wikipedia, the free encyclopedia
In general surgery, a Roux-en-Y anastomosis, less formally and precisely Roux-en-Y, is a surgically created (end-to-side) anastomosis between (1) the duodenum and the proximal jejunum or (2) a proximal segment of jejunum and a distal segment of the jejunum.

[edit] Overview
The name is derived from the surgeon that first described it (César Roux)[1] and the stick-figure representation; diagramatically, the Roux-en-Y anastomosis looks like the letter Y, where the two upper limbs of the Y represent the duodenum (or proximal segment of jejunum) and proximal jejunum and the lower part of the Y the distal jejunum.
Roux-en-Ys are used in several operations and collectively called Roux operations.[1]
[edit] Operations that make use of a Roux-en-Y
Schematic of gastric bypass using a Roux en-Y anastomosis.
- Some gastric bypasses for obesity.
- Roux-en-Y reconstruction following partial or complete gastrectomy for stomach cancer.[2]
- Roux-en-Y hepaticojejunostomy used to treat (macroscopic) bile duct obstruction which may arise due to:
- A common bile duct tumour or hepatic duct tumour (e.g. resection of cholangiocarcinoma)[3]
- a bile duct injury (e.g. cholecystectomy surgical misadventure, trauma)
- an infection/inflammation (e.g. pancreatic pseudocyst)
- Roux-en-Y choledochojejunostomy - indications same as Roux-en-Y hepaticojejunostomy.
