AIM:To study the therapeutic efficacy of temporary partially-covered metal stent insertion on benign esophageal stricture.METHODS:Temporary partially-covered metal stent wasinserted in 83 patients with benign esophageal stricture.Allthe patients had various dysphagia scores.RESULTS:Insertion of 85 temporary partially-covered metalstents was performed successfully in 83 patients with benignesophageal stricture and dysphagia was effectively remittedin all the 83 cases.The dysphagia score was 3.20±0.63(mean±SD) and 0.68±0.31 before and after stent insertion,and 0.86±0.48 after stent removal.The mean diameter ofthe strictured esophageal lumen was 3.37±1.23 mm and25.77±3.89 mm before and after stent insertion,and16.15±2.96 mm after stent removal.Follow-up time was from1 week to 96 months (mean 54.26±12.75 months).Thecomplications were chest pain (n=37) after stent insertion,and bleeding (n=12) and reflux (n=13) after stent removal.CONCLUSION:Temporary partially-covered metal stentinsertion is one of the best methods for treatment of benignesophageal stricture.

The dysphagia score was 3.20 ± 0.63 (mean ± SD) and 0.68 ± 0.31 before and after stent insertion, and 0.86 ± 0.48 after stent removal. The mean diameter of the strict esophageal lumen was 3.37 ± 1.23 mm and 25.77 ± 3.89 mm before and after stent insertion, and 16. 15 ± 2.96 mm after stent removal.
