Analysis of Post-Metallic Stent Placement Complications in the Treatment of Esophageal Strictures

Purpose To analyse the causes of complications that occurred in the 67 patients treated by metallic stent implanation,in order to study the prevention and treatment. Methods From June 1996 to August 2000,96 metallic stents were used for 78 patients with esophageal strictures. Covered stents ( n =59) and uncovered stents ( n =37) were chosen.Postoperative complications were analysed. Results Sixty seven cases of the 78 patients were complicated with chest pain, gastroesophageal regurgitation, postoperative recurrent stenosis,stent migration,esophagorrhagia esophageal perforation and cardiac arrhythmia.These symptoms disappeared or were relieved mostly by treatment. Conclusion The post stent placement complications in the treatment of esophageal strictures are preventable and can be rilieved by treatment if they occur.
