至今,治疗食管贲门失弛缓症的方法有三种:药物治疗、气体扩张和肌切开手术。尽管后两种方法的成功率达65%～90%,但可并发穿孔和返流。本实验通过括约肌内注射肉毒杆菌毒素(BT)治疗食管贲门失弛缓症,并与注射生理盐水和气体扩张相比较。 方法:16例新近诊断的食管贲门失弛缓症 So far, there are three ways to treat esophageal achalasia: drug therapy, gas expansion and myotomy. Although the latter two methods have a 65% to 90% success rate, perforation and regurgitation may occur. In this experiment, intramuscular injection of botulinum toxin (BT) in the treatment of esophageal achalasia, and injection of saline and gas expansion compared. Methods: 16 cases of newly diagnosed esophageal achalasia
