Abstract:
Objective To determine the curative effect of dilation for achalasia with temporary cardia stent in different diameters based on a long-term follow-up.Methods The study cohort was comprised of 135 patients of achalasia.Among them differentiated by stent diameters as followings:30 patients were treated under fluoroscopy with dilation of temporary cardia stent in 20 mm diameter(group A), 30 patients with dilation of temporary eardia stent in 25 mm diameter(group B),and 75 patients with dilation of temporary cardia stent in 30 mm diameter(group C).135 cardia stents were temporarily placed in the 135 patients and withdrawn after 3 -5 days via gastroscopy.All the stents were inserted and withdrawn successfully.The follow-up in all groups lasted 6-128 months.Results Six(20.0%)out of 30 patients,6(20.0%)out of 30 patients,5(22.7%)out of 22 patieuts,6(37.5%)out of 16 patients,5 out of 9 patients,3 out of 3 patients in group A exhibited dysphagia relapse during 6 months,1 year,3 years,5 years,8 years,and 10 years follow-up,respectively. Four(13.3%)out of 30 patients,4(13.3%)out of 30 patients,3(13.0%)out of 23 patients,4(22.2%)out of 18 patients,5(45.5%)out of 11 patients,and 3 out of 4 patients in group B exhibited dysphagia relapse during 6 months,1 year,3 years,5 years,8 years,and 10 years follow-up,respectively.No(0.0%)out of 75 patients, 1(1.5%)out of 66 patients,4(8.3%)out of 48 patients,6(18.2%)out of 33 patients,6(33.3%)out of 18 patients,2 out of 5 patients in group C exhibited dysphagia relapse during 6 months,1 year,3 years,5 years,8 years,and 10 years follow-up,respectively.Conclusion Dilation with temporary cardia metal stent in 30 mm diameter is the best dilation for achalasia in long-term follow-up.
