目的 评价食管内支架置入在食管良恶性狭窄中的临床应用价值 ,探讨支架的选择对疗效的影响。方法 36例食管狭窄患者 ,良性狭窄 5例 ;恶性狭窄 31例 ,其中 4例合并食管气管瘘 ,3例合并食管纵隔瘘。选用国产镍钛合金记忆网状支架 2 6根 ,带膜支架 14根 ,均在x线监视下经口腔置入内支架。结果 36例置入 4 0根支架成功 ,仅 1根带膜支架发生移位 ,治疗前吞咽困难 3级 16例 (44 4 % ) ,2级 2 0例 (5 5 6 % ) ,治疗后 3级 1例(2 8% ) ,2级 8例 (2 2 2 % ) ,1级 12例 (33 3% ) ,0级 15例 (41 7% ) ,总有效率 97 2 %。结论 内支架置入治疗食管良恶性狭窄简便、安全有效 ,并发症少 ,能迅速改善患者营养状况 ,大大提高了生存质量 ,为肿瘤进一步治疗创造条件。支架选择恰当能保持食管开通率和减少滑移率
Objective To evaluate the clinical value of esophageal stent placement in benign and malignant esophageal stenosis and to explore the effect of stent selection on the curative effect. Methods Thirty-six patients with esophageal stenosis, five patients with benign stenosis and 31 patients with malignant stenosis were enrolled in this study. Four of them were combined with esophageal tracheal fistula and three with esophageal mediastinal fistula. Choose nickel-titanium alloy memory mesh stent 26, with stent 14, both under the x-ray monitoring into the stent within the mouth. Results Thirty-six cases were successfully treated with 40 stents. Only one stenting was transplanted. There were 16 cases (44.4%) with grade 3 dysphagia before treatment, 20 cases (55.6%) with grade 2 and 3 Grade 1 (28%), grade 2 8 (22%), grade 1 12 (33 3%), grade 0 15 (41.7%), with a total effective rate of 97 2%. Conclusion Stent implantation in the treatment of benign and malignant esophageal stenosis is simple, safe and effective, with fewer complications, can quickly improve the nutritional status of patients, greatly improving the quality of life and creating conditions for the further treatment of cancer. Stent selection properly to maintain esophageal opening rate and reduce the slip rate
