镍钛记忆合金食管内支架治疗食管疾病的临床研究

CLINICAL STUDY ON SELF EXPANDING INTRALUMINAL ESOPHAGEAL NITINOL STENT IN THE TREATMENT OF ESOPHAGEAL DISEASES

作者应用镍钛记忆合金食管内支架治疗各类食管疾病共９例，置入支架前吞咽困难Ｃｗｉｋｉｅｌ分级均达２－３级，置入后立即缓解，Ｃｗｉｋｉｅｌ０－１级者为１００％。全组病例除有异物感及轻微胸背疼痛外，无严重并发症发生。随访：除１例于置入后二周出现支架移位，后期衰竭死亡，１例置入后三月因肿瘤过生造成再狭窄外，其余病例随访１１－２３个月均存活，且支架通畅，进食良好。结论：镍钛记忆合金支架可确切有效地解除食管良、恶性狭窄，缓解吞咽困难，有效堵塞瘘口，防止食物及唾液外漏，是一种简便、有效且应用前景广阔的食管疾病治疗手段。

A self expanding intraluminal esophageal nitinol stent was implanted in 9 patients for treating esophageal diseases. The patients included postoperative anostomotic leakage, anastomotic stenosis, and malignant esophageal strictures. The dysphagia was considerably relieved in all patients immediately after stent insertion. All stents were implanted under fluoroscopic guidance. Successful stent placement was achieved in 8 of 9 cases at first trial. There were no serious stent related complications, and all patients only had foreign body feeling and light chest pain. Stent migration happened in 1 case, and ingrowth of tumor into stent in another one. The other 7 patients were followed up for 11 to 23 months. In conclusion, the self expanding intraluminal esophageal nitinol stent appears to be effective, safe and promising in the treatment of patients with benign or malignant esophageal diseases.
