Abstract:
Objective To investigate the complications and management of nitinol self-expandable metal stent (cSEMS) in treatment of refractory esophageal strictures in children. Methods The clinical data were reviewed for 9 pediatric patients with refractory benign esophageal disorders from May 2009 to December 2016, specially designed cSEMS were applied to them, data about effects and complications were collected during regular follow-ups. Results Successful cSEMS placement was performed in 9 children, the symptom of dysphagia was obviously alleviated after implantation, all patients underwent vomiting and chest pain 1~7 days after operation; 1 case could not put up with the pain, so the stent had to be removed in 36 hours after implantation; 2 cases developed a recurrent stricture within 3 months after stent removal, growth of mild granulation tissue was found in 1 case; In the case with esophageal fistulas, migration and poor adherence to the esophagus was occurred in 3 days after implantation, then a new designed cSEMS with bigger proximal tip was planted in the same place 1 week later, 2 months after stent removed, fistula was healed. Conclusion Placement of cSEMS is safe and effective in treating pediatric patients with refractory esophageal stricture. However, complications associated with stent placement should not be ignored, individually designed stent and timely management of the complications are quite important in order to enhance clinical efficacy.
