目的回顾总结使用记忆合金网状支架治疗食管狭窄的远期疗效。方法应用国产镍钛合金网状支架治疗食管狭窄38例,术后6、12、24个月随访,重新评定疗效。结果术后6、12、24个月的有效率分别为85.7%、69.0%、35.7%。结论食管狭窄患者的本身因素(疤痕体质、肿瘤复发)、放置支架的准确性等影响手术的远期疗效。网状支架有刺激组织增生的可能。吻合口狭窄者,其肉芽组织(非肿瘤组织)呈向上性生长;未手术的食管癌复发,其生长向上下两个方向漫延,没有明显的偏向。网状支架治疗食管狭窄近期疗效显著,远期疗效一般,故网状支架是治疗食管狭窄近期疗效较好的方法。
Objective To review and summarize the long-term effects of esophageal stenosis treated with memory alloy mesh stent. Methods 38 patients with esophageal stenosis treated with a domestic nickel-titanium mesh stent were followed up at 6, 12, and 24 months after operation to reevaluate the curative effect. Results The effective rates at 6, 12 and 24 months after operation were 85.7%, 69.0% and 35.7% respectively. Conclusion Esophageal stenosis in patients with their own factors (physical scars, tumor recurrence), the accuracy of placement of stents affect the long-term efficacy of surgery. Mesh scaffolds have the potential to stimulate tissue proliferation. Anastomotic stenosis, the granulation tissue (non-tumor tissue) was upward growth; esophageal cancer without surgery recurrence, the growth of the two directions up and down the spread, there is no obvious bias. Mesh stent treatment of esophageal stenosis has a significant short-term effect, long-term efficacy in general, so the mesh stent is the treatment of esophageal stenosis better curative effect.
