目的：探讨用食道内支架技术治疗食道恶性狭窄的疗效、技术要点及并发症。材料和方法：４６ 例中，男４０ 例，女６ 例，年龄５６ ～８０ 岁（ 平均６４ 岁） 。其中食道癌３９ 例，贲门癌２ 例。食道癌或贲门癌术后吻合口肿瘤复发５ 例。选用带膜支架３４ 例，不带膜支架１２ 例。均在Ｘ 线监视下，经口腔植入内支架。结果：４６ 例中４４ 例植入成功。４４ 例植入内支架的患者吞咽困难明显改善。随访６ ～２４ 个月，平均生存期８ 个月，最长２０ 个月。２ 例在２ 个月内肿瘤向腔内生长致再狭窄，再植入内支架症状改善。１ 例内支架植入后２ 个月发生移位，经手术取出，再植入。１ 例内支架植入１ 周后死亡。结论：食道内支架是治疗食道恶性狭窄的有效方法；吻合口或贲门癌所致狭窄以选不带膜支架为佳；配合必要的化、放疗可减少再狭窄，并且可提高生存期。
Objective: To investigate the efficacy, technical points, and complications of esophageal stenting in the treatment of malignant esophageal stenosis. Materials and Methods: Of the 46 cases, 40 were males and 6 were females, aged 56 to 80 years (average 64 years). There were 39 cases of esophageal cancer and 2 cases of cardiac cancer. Esophageal or cardiac cancer recurred in 5 cases after anastomotic cancer recurrence. Thirty-four patients with stents and 12 stents without stents were selected. Under X-ray monitoring, the stents were implanted orally. Results: Of the 46 cases, 44 cases were successfully implanted. Dysphagia was significantly improved in 44 patients with implanted stents. Followed up for 6 to 24 months, with an average survival period of 8 months and a maximum of 20 months. In 2 cases, the tumor grew into the lumen within 2 months and restenosis occurred, and the symptoms of stent implantation improved. One month after the implantation of the stent, there was a displacement, which was removed by surgery and then implanted. One patient died after 1 week of stent implantation. Conclusions: Esophageal stenting is an effective method for the treatment of malignant esophageal stenosis; anastomosis or cardiac cancer-induced stenosis is better than non-membrane stents; combined with necessary chemotherapy and radiotherapy can reduce restenosis and improve survival.
