[目的]探讨多次置入多枚食管支架治疗食管恶性狭窄的临床价值。[方法]9例患者中8例患者分别于置入第1枚支架后3、5、8、16、17、17、20、24个月因肿瘤进展或炎性增生致再狭窄而置入第2枚支架,其中1例食管中段癌患者于第2枚支架置入后7个月因肿瘤进展致再狭窄而置入第3枚支架。另1例患者支架置入后行放疗引起上口瘘而置入第2枚支架。[结果]9例患者因肿瘤进展或炎性增生及食管瘘多次置入多枚食管支架后均开通食管梗阻,提高了患者生存质量,延长了患者生存时间。[结论]食管恶性狭窄支架置入后肿瘤进展或局部炎性增生等造成再次狭窄及食管气管瘘,采取多次置入多枚食管支架有着重要的临床价值。
[Objective] To explore the clinical value of multiple esophageal stent placement in the treatment of esophageal malignant stenosis. [Method] 8 patients in 9 patients were placed in the third, fifth, eighth, 16th, 17th, 17th, 20th, 20th and 24th month after the first stent implantation due to tumor progression or inflammatory hyperplasia Two stents, of which 1 case of esophageal cancer in the second stent after 7 months due to tumor progression caused by restenosis and placed in the third stent. Another case of patients with stent implantation after radiotherapy induced upper fistula into the second stent. [Results] Nine patients with esophageal obstruction after multiple esophageal stent placement due to tumor progression or inflammatory hyperplasia and esophageal fistula increased the patient’s quality of life and prolonged the survival time of patients. [Conclusion] Restenosis and esophageal tracheal fistula caused by tumor progression or local inflammatory hyperplasia after stenting of malignant esophageal strictures have many important clinical values.
