目的：用金属食管镜扩张食管狭窄并置入食管支架，改善恶性食管狭窄及食管瘘患者的生活质量。方法：患者经全麻或表麻在金属食管镜下扩张狭窄的食管，然后置入双喇叭硅胶管或镍钛合金支架。4例应用双喇叭硅胶管，24例应用镍钛记忆合金支架，所有患者食管扩张及支架直入顺利，术后进食无障碍。2例（72％）支架向上移位，23例（82．8％）发生胸骨后疼痛，7例（25．0％）发生胃液返流，4例（14．3％）发生阻塞，1例（3．6％）于术后两个月死于术后食管大出血。结论：用金属食管镜扩张恶性食管狭窄，人工支架置人是改善恶性食管狭窄患者生活质量的一种理想姑息治疗方法，支架置入方便，无严重并发症发生。
Objective: To use metal esophagoscopes to dilate esophageal strictures and place esophageal stents to improve the quality of life in patients with malignant esophageal stenosis and esophageal spasm. METHODS: Patients underwent dilating the narrow esophagus under metal esophagoscopy with general anesthesia or table anesthesia, and then placed a double-tipped silicone tube or NiTi stent. In 4 cases, dual-trumpet silicone tubes were used, and in 24 cases nickel-titanium memory alloy stents were used. All patients had esophageal dilatation and stenting straight-in, and they had no access to food after surgery. In 2 patients (72%), the stents were displaced upward. 23 cases (82.8%) experienced poststernal pain, 7 cases (25.0%) developed gastric reflux, 4 cases (14.3%) developed obstruction, and 1 case occurred. (3.6%) died of postoperative esophageal bleeding two months after surgery. Conclusion: The use of metal esophagoscope to dilate malignant esophageal stenosis and artificial stent placement is an ideal palliative treatment to improve the quality of life of patients with malignant esophageal stenosis. Stent placement is convenient and no serious complications occur.
