Updates in the research of Roux stasis syndrome

Abstract

Roux-en-Y procedure has widely been used for digestive tract reconstruction after distal or total gastrectomy, and the Roux stasis syndrome is one of the most common complications. The symptoms of Roux stasis syndrome include abdominal pain, abdominal distention, nausea, vomiting and anorexia. Abdominal movement of the intestinal loop and reversed peristalsis cause delayed passage of gastric contents, which is the main cause of the Roux stasis syndrome. Prokinetic agents and electronic stimulation have been investigated as potential nonsurgical treatment methods for Roux stasis syndrome. Uncut Roux-en-Y anastomosishas been found to be effective in preventing Roux stasis syndrome. In the future, precise evaluation of the psychological changes of the digestive tract after the Roux-en-Y anastomosis and understanding the mechanism of Roux stasis syndrome would be more effective to help the surgeons to resolve the problems. Key words: Roux stasis syndrome; Gastrectomy; Digestive tract reconstruction
