Endoscopic decompression with memorized Nitinol alloy network stent for malignant stricture of esophagus and cardia:report of 30 cases

Objective:To assess the value of endoscopic decompression with memorized Nitinol alloy network stent in treatment of malignant stricture of esophagus and cardia.Methods:Thirty patients with unrespectable malignant stricture of esophagus and cardia were emplaced memorized Nitinol alloy network stent through gastroscope.For patients with serious stricture,the stents were inserted after Savary's dilation.Results:Successful stent placement was achieved in all the 30 cases,with an effective rate of 100%;28 patients were emplaced one stent and 2 patients two stents.Conclusions:The emplacement of Nitinol alloy network stent is effective for treatment of malignant stricture of esophagus and cardia (operation useless or unrespectable).It may extend the life span of the patients and improve their quality of life.The operation is safe and applicable.
