Boston's balloon dilatation for treatment of cardiac achalasia / 介入放射学杂志

ABSTRACT

Objective To review and summerize effectiveness and method of the Boston's balloon dilation in cardiac achalasia. Methods The intensified guide wire was inserted into stomach through mouth cavity under TV controll. The Boston's balloon was inserted to the cardiac stricture through the guide wire and dilatated with 15% contrast medium with to a maximum diameter for five minutes and then the balloon was dilatated again for 3～5 minutes, all together for 3～4 times. The severe stricture must be pre dilatated with 20～25mm diameter balloon. Results The balloon insertion was technically successful in all 26 patients. The once succese of ballon dilation was achieved in 24 patients and twice in other 2. Follow up time was from 2 weeks to 31 months(mean 10.6 months). Recurrent stenosis had not occurred in all patients. Remission rate of dysphagia was 100%. Esophageal reflux occurred in 3 patients. Conclusions The Boston's balloon dilatation is simple and effective for treatment of cardiac achalasia. The method sometimes may replace surgical procedure.
