MTN-S Nicked-Titamium Memotial Alloying Covered Stent In The Treatment Of Esophaged Anastomosis

Background:Esophageal anastomosis esophageal stenosis is a common post-operative complications, second surgery risks are great, was very difficult. Since the Song and other foreign scholars will stand for the disarmament of esophageal obstruction due to food has been a large number of studies confirm, and esophageal stents in malignant esophageal stenosis on the clinical efficacy. Abroad in recent years, research data indicate that esophageal stent-graft anastomosis in the treatment of esophageal stricture on the equally effective, domestic related literature have been reported, but the lack of bulk reported in the literature on the observation of long-term efficacy remains to be further studied。Objective:By observing the esophageal anastomotic stricture underwent esophageal stent implantation before and after eating status, and recovery of patients after stent eating status changes, the incidence of complications, remember to observe the shape of MTN-type titanium-nickel alloy coating can be recovery of esophageal stents in the esophagus after the lifting effect of anastomotic stenosis.Methods:Will be in March 2008-2.01 thousand years, in January, the doctor in my hospital postoperative anastomotic stricture of the esophagus 47 patients were divided into before surgery, two control groups, according to intraoperative imaging of the MTN-type shape, select the appropriate recoverable memory titanium-nickel alloy coated stents,47 stents were accurate positioning, the success of the release. And the discipline of clinical symptoms observed remission rate, complication rate, frame stability, stent removed at 4 weeks,8 weeks, 12 weeks in patients with clinical symptoms of dysphagia grading, complication rate, body weight change, survival station.Results:1, Stent implantation technical success rate was 100% clinical remission rate of 95%, and after the emergence of a transient retrosternal pain, nausea, vomiting, some patients have foreign body sensation, without serious complications. Dysphagia were graded 0.8 weeks gained an average of 5.7kg.2, 47 stents were successfully recovered in the DSA perspective, technical success rate was 100%, of which 1 patient stent in after the first 17 days of loss, dysphagia grade after stent removal of 2, compared to before surgery to reduce the 2; 1 cases stent in patients at 4 weeks after repeated displacement, loss, dysphagia following stent out of three, compared to preoperative lower one, the latter confirmed by endoscopy caused by scar formation of granuloma, the patient died 10 weeks after operation was caused by multiple transfers MODS; 39 patients with postoperative dysphagia dropped to 0.Conclusion:1, MTN-based shape-memory titanium-nickel alloy coated stent in the treatment of recyclable esophageal anastomotic stricture of the clinical application of curative effect, less complications, safe and reliable.2, Stent recovery time at home and abroad there is no consensus-building, protection of its in-depth study will be efficacy at the same time, reduce the incidence of complications, to alleviate the suffering of patients.
