The Roux en-Y-reconstruction is a surgical procedure for the reconstruction of the continuity of the intestinal tract after stomach resection or gastrectomy.
Procedure
The stomach is partially or entirely removed. The resulting duodenal stump is closed to from a blind end. The stomach stump or the esophagus is then connected isoperistaltically to the pulled up jejunum.
The jejunum cut off from the duodenum and connected to the stomach (gastrojejunostomy) or the esophagus (esophagojejunostomy). The duodenal stump is then connected to the side of the pulled up jejunum (Y-anastomosis). The distance between upper and lower anastomosis whould be no less than 30-40 cm.
Consequences
The Roux en-Y-reconstruction is the most common reconstructive procedure after gastric resection used today. It effectively avoids backflow of bile and thus gueards against ulcus formation and carcinoma of the anstomoses.
Complications can be dumping-syndrom or leakage or stenosis of the anastomoses.
