Roux-en-Y anastomosis

Roux-en-Y anastomosis

In general surgery, a Roux-en-Y anastomosis, less formally and precisely Roux-en-Y, is a surgically created (end-to-side) anastomosis. Typically, it is between small bowel and small bowel that is distal (or further down the gastrointestinal tract) from the cut end.Roux operation. whonamedit.com.

Overview

The name is derived from the surgeon that 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 a proximal segment of small bowel and the distal small bowel it joins with, and the lower part of the Y the distal small bowel (beyond the anastomsosis).

Roux-en-Ys are used in several operations and collectively called Roux operations.

Operations that make use of a Roux-en-Y

* Some gastric bypasses for obesity.
* Roux-en-Y reconstruction following partial or complete gastrectomy for stomach cancer. [Surgery to remove stomach cancer. cancerhelp.org.uk. URL: [http://www.cancerhelp.org.uk/help/default.asp?page=3917 http://www.cancerhelp.org.uk/help/default.asp?page=3917] . Accessed on: February 7, 2008.]
* 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) [Lawrence PF. Essentials of general surgery. 3rd Ed. Lippincott Williams & Wilkins. 2000. ISBN 0-683-30133-0.]
** 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".
