Results of 20 dilatation sessions in 15 patients with achalasia cardia were assessed to determine the safety and efficacy of polyethylene balloon achalasia dilators (Rigiflex).
All patients underwent an initial dilatation by inflating a 30 mm balloon to 9 psi for one minute. Need for subsequent dilatations was assessed on symptom assessment; 35 mm balloon was used for repeat procedure.
Overall success rate was 93.3%. The 30 mm balloon achieved a satisfactory result in 73.3% and the 35 mm balloon in 75% of the remainder. Only one patient needed surgery. No short-term complications were observed. The only late complication encountered over an average follow-up period of 16.2 months was gastroesophageal reflux in two patients.
Dilatation using Rigiflex dilators is a safe, effective and simple procedure for treating patients with achalasia.
评估15例贲门失弛缓症患者20次扩张治疗的结果，以确定聚乙烯球囊贲门失弛缓症扩张器（Rigiflex）的安全性和有效性。
所有患者均通过将30毫米球囊充气至9磅/平方英寸持续1分钟进行首次扩张。根据症状评估确定是否需要后续扩张；重复操作时使用35毫米球囊。
总体成功率为93.3%。30毫米球囊在73.3%的患者中取得了满意的效果，其余患者中35毫米球囊的成功率为75%。只有1例患者需要手术。未观察到短期并发症。在平均16.2个月的随访期内，仅遇到2例患者出现胃食管反流这一晚期并发症。
使用Rigiflex扩张器进行扩张是治疗贲门失弛缓症患者的一种安全、有效且简单的方法。
