波士顿科学集团推出的Enteryx能够有效治疗GERD

来自临床试验的结果证实：患者对使用Enteryx方案减轻胃食管返流疾病（GERD）症状的效果感到很满意。

Enteryx是一种门诊手术，一个小时之内即可完成。医生将柔软的内窥镜插入患者嘴巴和食管。内窥镜帮助医生观察患者食管和胃的内壁。将一个小针插入内窥镜的工作管腔，用于注射Enteryx溶液，这是一种共聚物，海绵样物质，设计用于帮助下段食管括约肌（LES）在胃和食管之间形成更有效的屏障，从而减轻GERD的症状。Enteryx是波士顿科学集团的产品。

印地安那州大学医学中心医学系、医学和放射学教授Glen Lehman医生观察说：“这些临床试验的结果证实了Enteryx方案在控制GERD症状方面的安全性和效能，与每日使用质子泵抑制剂相比较，Enteryx方案能够使患者产生最高水平的满意度。”

这些临床试验结果在2005年5月芝加哥举行的年度消化疾病周会议上做了报道。在临床试验中，问卷调查表显示：接受Enteryx方案的患者反映GERD症状得到了确实的缓解，能够自由的进食和饮水，睡眠得到改善，总体治疗满意程度很高。
 
Studies Support Use of Enteryx for GERD
 
The results of four clinical trials have demonstrated patient satisfaction and the effectiveness of the Enteryx procedure in relieving the symptoms of gastroesophageal reflux disease (GERD).

Enteryx is an outpatient procedure that usually takes less than an hour to complete. A doctor passes a long flexible tube called an endoscope through a patient’s mouth and into the esophagus. The endoscope lets the doctor see the lining of the patient’s esophagus and stomach. A small needle, inserted through the working channel of the endoscope, is used to inject the Enteryx solution, a copolymer, into the muscle layer of the esophagus. Once injected, the Enteryx solution forms a soft, sponge-like material designed to help the lower esophageal sphincter (LES) form a more effective barrier between the stomach and the esophagus, reducing the symptoms of GERD. Enteryx is the product of Boston Scientific Corp. (Natick, MA, USA).

“These clinical trial results demonstrate the safety and efficacy of the Enteryx procedure at controlling GERD symptoms, and show that the Enteryx procedure contributes to high levels of patient satisfaction as compared to daily proton pump inhibitor (PPI) treatments,” observed Glen Lehman, M.D., professor of medicine and radiology, department of medicine, Indiana University Medical Center (Bloomington, IN, USA; www.indiana.edu/medical).

The trial results were presented at the annual Digestive Disease Week conference in Chicago (IL, USA) in May 2005. In one trial, a questionnaire revealed that patients who had the Enteryx procedure reported substantial improvement in GERD symptom control, freedom to eat and drink, ability to sleep better, and overall higher rates of treatment satisfaction.
