Long-term follow-up of two interventional procedures for achalasia

Objective To observed the long-term follow-up of the two types of interventional procedure for achalasia. Methods The study cohort was comprised of 140 patients of achalasia including 70 patients treated under fluoroscopy with pneumatic dilation (group A) and 70 with temporary partially covered metal stent dilation (group B). Results One hundred and forty dilations were performed on the 70 patients of group A with complications of chest pain (n=35), reflux (n=18), and bleeding (n=8); 38 patients of relapsing dysphagia during a 12-month follow-up, and 50 patients out of 60 of recurrent dysphagia during a 36-month follow-up. Seventy partially covered expandable metal stents were temporarily placed in the 70 patients of group B and withdrawn after 3-7 days via gastroscopy with complications of chest pain (n=28), reflux (n=15), and bleeding (n=9); 7 patients out of 70 exhibited dysphagia relapse during a 12-month follow-up, and 9 out of 58 patients exhibited dysphagia relapse during a 36-month follow-up. All the stents were inserted and withdrawn successfully. The follow-up in groups A-B lasted for 12-96 months. Conclusion Temporary partially covered metal stent dilation is one of the best methods of interventional procedure for achalasia in long-term follow-up.
