目的探讨晚期结直肠恶性肿瘤伴梗阻患者的内镜直视下内支架治疗的效果。方法对12例晚期结直肠恶性肿瘤伴梗阻的患者行内镜直视下记忆合金支架置入术,观察术后梗阻缓解以及并发症发生情况。结果本组患者导丝插入后支架置入一次成功率100%。12例支架放置成功后肠梗阻症状即可缓解。其中有1例患者出现肛门疼痛,复查肠镜及腹部平片,支架在位良好,给予消炎痛对症治疗后症状缓解;1例出现少量便血,给予常规止血治疗后好转。12例患者中无支架滑脱,堵塞,结肠穿孔等并发症发生。结论内镜直视下内支架术是治疗晚期结直肠恶性肿瘤伴梗阻患者有效、安全的方法。
Objective To investigate the effect of endovascular stent-graft under endoscopic surgery in patients with advanced colorectal malignancy and obstruction. Methods 12 cases of advanced colorectal malignant tumor with obstruction in patients undergoing endoscopic fixation with memory alloy stent placement, obstruction relief and complications were observed postoperative complications. Results This group of patients with guide wire insertion stent 100% success rate. 12 cases of stent placement successfully after the symptoms of intestinal obstruction can be alleviated. One patient had anorectal pain, colonoscopy and abdominal plain film were reviewed, and the stent was in good position. Symptomatic relief was given after symptomatic treatment of indomethacin. One patient had a small amount of blood in the stool and was improved after conventional hemostasis. No stent slippage, blockage, colonic perforation and other complications occurred in 12 patients. Conclusion Endoscopic stenting is an effective and safe method for the treatment of advanced colorectal cancer with obstruction.
