目的探讨内镜下植入钛镍记忆合金支架治疗结直肠恶性梗阻的疗效和临床价值。方法对32例结直肠恶性梗阻施行了X线辅助下经内镜植入钛镍记忆合金支架术。结果 32例患者中,31例结肠内支架植入成功,1例发生肠穿孔,成功率为96.9%。26例为姑息性治疗,2例分别于支架植入后3个月、6个月支架阻塞,再行支架植入或内镜下气囊扩张,未发生支架移位。6例于支架植入后1-2周行外科手术治疗,Ⅰ期吻合,术后恢复顺利,未发生感染、吻合口瘘等并发症,生存6个月以内32%(10/31),6个月以上68%(21/31),5例已超过12个月,现仍在随访中。结论内镜下植入钛镍记忆合金支架治疗结直肠恶性梗阻能够有效缓解患者的梗阻症状及并发症,可降低患者的创伤和痛苦,提高生活质量。
Objective To investigate the efficacy and clinical value of endoscopic titanium-nickel memory alloy stent implantation in the treatment of colorectal malignant obstruction. Methods 32 cases of colorectal malignant obstruction underwent X-ray assisted implantation of titanium-nickel-titanium alloy stent. Results Of the 32 patients, 31 cases of colonic stent implantation, 1 case of intestinal perforation, the success rate was 96.9%. Twenty-six patients were treated with palliative treatment. Two patients were blocked at 3 months and 6 months after stent implantation respectively. Stent implantation or endoscopic balloon dilatation was performed in 2 patients. Stent displacement did not occur. Six cases were treated with surgical operation 1-2 weeks after stent implantation. The patients in stage I were anastomosed and recovered smoothly. There were no complications such as infection and anastomotic fistula, 32% (10/31) of the patients survived within 6 months, 6 More than 68% (21/31) months, 5 cases have been more than 12 months, is still under follow-up. Conclusion Endoscopic implantation of titanium-nickel memory alloy stent in the treatment of colorectal malignant obstruction can effectively alleviate the symptoms and complications of obstruction in patients, reduce trauma and pain, and improve the quality of life.
