目的探讨外放射对中晚期食管癌支架治疗的影响。方法 73例不能切除或拒绝手术治疗的中晚期食管癌合并严重狭窄患者分为两组， A组患者先行内镜支架扩张，术后辅以腔内放疗和热疗； B组患者先接受 6000－ 7000rad的外放射治疗， 3－ 6个月后行内镜下的支架扩张与腔内放射和热疗。结果 A组 42例，支架均一次顺利成功置入，成功率为 100％，术后并发症少。 B组 31例支架置入成功率为 29％，术后并发症发生率高，包括术后大出血，持续严重胸痛，食管气管漏，支架扩张不良和支架移位再狭窄。结论外放射治疗明显降低食管癌患者支架置入的成功率，术后并发症更多见更严重。
Objective To investigate the effect of external radiation on the treatment of advanced esophageal cancer. Methods A total of 73 patients with advanced esophageal cancer and severe stenosis who could not be removed or refused surgery were divided into two groups. The patients in group A underwent endoscopic stent dilatation and postoperative radiotherapy and hyperthermia. Patients in group B received 6000- External radiation therapy at 7000 rad and endoscopic stent-dilatation and intracavitary radiation and hyperthermia 3-6 months later. Results A group of 42 cases, the stent were successfully successfully inserted, the success rate was 100%, less postoperative complications. The success rate of stent implantation in group B was 29%. The incidence of postoperative complications was high, including postoperative bleeding, persistent severe chest pain, esophageal tracheal leakage, stent dilatation and stent restenosis. Conclusion External radiotherapy can significantly reduce the success rate of stent implantation in patients with esophageal cancer, postoperative complications are more serious.
