Abstract:
Objective To explore the feasibility of microinvasive technique in high level malignantesophageal obstruction and to provide the palliative therapy that can't be dredged by traditional methods. Methods There were 39 patients suffered from high level esophageal obstruction,involving the segments from esophageal circular pharynx to 12mm below. Tube-reticular nitinol metal stents woven by single thread were placed in orally to dredge the esophagus under fluoroscopic guidance after repeated tolerant expanding performance through expandable catheter. Interventional chemical therapy were administrated through blood-supply vessels. Results Thirty nine patients were grafted with 46 high level esophageal stents. 34 patients accepted 156 times of interventional chemical therapy. All patients restored with fine residue diet without showing side-effects except slight pain and tolerant uncomfortable feeling. The survival rate of the patients with both interventional chemical therapy and stents was longer than those with stent therapy alone. Conclusion Cervical high level segment of esophagus shouldn't be the restricted zone in the management of inner-stents. Interventional chemical therapy showed tumor-inhibiting effect in the cervical malignant diseases.
