目的 总结放疗前后行有效食管扩张及支架置放的疗效。方法 未行放疗及放疗后两组均用锥形塑料探条扩张器扩张食管狭窄段，扩至１３ｍ ｍ 时采用置入器置放支架。结果 ５３ 例中未行放疗的 ３０ 例，扩张均为显效，显效率达１００％ （３０／３０），支架均１ 次顺利置放成功，成功率达 １００％（３０／３０）；行放疗的 ２３ 例中扩张及支架置放的总有效率仅为 １７３９％ （４／２３）；未行放疗组和放疗组扩张的显效率，支架置放的成功率二者差异非常显著（ Ｐ ＜ ０００１）。同样术前，术后进食标准积分的改善率差异也非常显著。结论 对既需要放疗，又需要支架置放的患者，应先行支架置放，后行放疗，以提高成功率。
Objective To summarize the effects of effective esophageal dilatation and stent placement before and after radiotherapy. Methods Before radiotherapy and radiotherapy, the pyramidal plastic probe dilators were used to expand the esophageal strictures, and the stent was placed with the instrument when expanded to 13 m. Results In all of the 53 cases, 30 cases were treated with radiotherapy and the expansions were markedly effective and the markedly effective rate was 100% (30/30). The stent was successfully placed in one case with a success rate of 100% (30/30) The total effective rate of expansion and stent placement was only 1739% (4/23) in 23 cases. There was a significant difference between the two groups in the success rate of stent placement without radiotherapy and radiotherapy (P < 0 001). The same preoperative and postoperative standard points of improvement of the difference is also very significant. Conclusion For patients who need both radiotherapy and stent placement, the stent should be placed in the first place and followed by radiotherapy to improve the success rate.
