暂时性金属支架扩张与水囊扩张治疗食管、贲门癌术后吻合口良性狭窄的对比研究

搞要:目的探讨暂时性金属支架扩张治疗食管、贲门癌术后吻合口良性狭窄的远期疗效。方法支架扩张组16例,置入支架1周后取出,定期随访,如再次出现狭窄,重复支架扩张;水囊扩张组15例,水囊扩张1次,1周后再次水囊扩张1次,定期随访,再度出现狭窄则重复水囊扩张。两组均随访治疗1a。结果支架扩张组1个月内仍能正常进食者占87.4%(14/16);而水囊扩张组1个月内能正常进食者占26.7%(4/15)。支架扩张组因再度狭窄在1a内重复支架治疗平均每例2.75次(包括首次);而水囊扩张组因再度狭窄在1a内重复水囊扩张治疗平均每例9.40次(包括首次)。结论暂时性金属支架扩张在治疗食管、贲门癌术后吻合口良性狭窄的远期疗效方面明显优于水囊扩张。

A comparison of temparary placement of expandable stent and balloon dilatation in treatment of anastomotic steruosis after operation on esophagus or preventriculus cancer

[Objective] To investigate the long-term efficacy of temporary placement of expandable metallic stent in the treatment of anastomotic stenosis after operation on esophagus or preventriculus cancer. [Methods] Stent group: Expandable metallic stents were temporarily placed in 16 patients with anastomotic stenosis and drawn out within 7 days. Balloon group: Balloon dilatation was applied two times in a week in 15 patients with anastomotic stenosis. Follow-up periods of all patients was 12 months. IF stenosis had recured, expandable metallic stents would have been temporarily placed once again in the patients of stent group and balloon dilatation would have been applied once more in the patients of balloon group. [Results] There was no dysphagia for 87.4% of the patients of stent group within one month after stent dilatation and for 26.7% of the patients of balloon group within one month after balloon dilation. Every patient of stent group was equally treated 2.75 times by stent dilatation and every one of balloon group 9.40 times by balloon dilatation in one year. [Conclusions] Temporary stent dilatation is superior to balloon dilatation in the treatment of anastomotic stenosis in the respect of Long-term efficacy.
