Clinical application of covered self-expending stent for malignant esophageal and duodenal strictures or fistulas

Objective To evaluate the value of covered self-expending metallic stent in the management of malignant esophageal and duodenal strictures or fistulas and explore the treatment for the associated common complications.Methods With interventional procedure under fluoroscopic guidance,95 self-expending mesh stents were implanted in 87 patients,including esophageal carcinoma(50 cases),esophagogastric anastomotic stenosis(23 cases),gastroduodenal malignant stenosis(5 cases),esophagobronchial fistula(3 cases),esophagogastric anastomotic fistula(6 cases).Results Stent placement was successful in all patients at the first trial,having no instant complication except one acute bleeding during the procedure and all of them with relief of stenostic complaint,restoration of clictelic function and closure of fistulas.The long-term curative effect showed something to do with different kind of disease,and the related treatment.Conclusion Self-expending metallic covered mesh stent is safe,effective and less complication;and could be further promoted with addition of radiotherapy and(or)chemotherapy.
