Roux淤滞综合征研究现状

Updates in the research of Roux stasis syndrome

Roux-en-Y手术方式是远端胃切除术后及全胃切除术后消化道重建的主要方式,Roux淤滞综合征是其常见术后并发症之一.Roux淤滞综合征是指患者行Roux-en-Y消化道重建术后出现的一系列症候群,主要包括腹痛、腹胀、恶心、呕吐及食欲减退等胃肠道排空障碍的症状.目前认为,Roux-en-Y术后Y形肠襻运动异常,产生逆向蠕动,导致其内容物排空障碍,是引发Roux淤滞综合征的主要原因.药物及电刺激的治疗方式对该综合征有一定治疗效果,通过“非离断式Roux-en-Y吻合术”预防该综合征的发生已得到广泛认可和应用.更准确地测定Roux-en-Y术后消化道的生理变化,解释Roux淤滞综合征的发生机制,将更有效地指导临床医师治疗该病.

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.＆quot;Uncut Roux-en-Y anastomosis＆quot; has 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.
