Abstract:
Objective To evaluate the long-term results of balloon dilatation for benign esophageal stricture and stent implantation for malignant esophageal stricture.Methods Balloon dilatation and stent implantation were performed in 156 cases,of which 12 cases received balloon dilatation in benign esophageal stricture and 134 cases received metallic stents,9 cases received balloon dilatation in malignant esophageal stricture of 143 cases.Results During a follow-up period of 1～48 months,61 cases died with a mean survival period of 8.9 months(1～33 months).Recurrent stenosis occurred in 63 cases(47%)who had to receive ballon dilatation or another stent implantation procedure,the stent was obstructed due to food and mucus in 3 cases,stricture at the upper end in 19 cases and the both ends in 8 cases.Conclusion Stent implantation is an effective palliative treatment for esophageal carcinoma with severe dysphagia.Tumor and hamartoplasia are the main cause of recurrent stricture.Covered stents can reduce the rate of recurrent stricture.
