【摘要】 目的探讨金属内支架治疗直结肠恶性狭窄和梗阻的临床意义和效果。方法47例无手术治疗指征的直、结肠恶性狭窄和梗阻,在X线透视下,经肛门置入镍钛记忆合金网状支架。结果47例患者,共植入镍钛记忆合金网状支架53枚(6例因再次梗阻二次植入支架)。43例支架一次置入成功,占91.5%(43/47),4例经二次支架置入成功,占8.5%(4/47)。2例肿瘤破溃瘘道形成病例,置入覆膜支架成功封堵瘘口。所有病例支架置入后梗阻症状迅速解除,腹胀逐渐消失,可进半流质饮食,一般情况好转。生存6个月以内29.8%(14/47),6个月以上70.2%(33/47),2例已超过13个月,现仍在随访中。结论直结肠金属内支架置入术,是治疗无手术指征的直结肠恶性狭窄和梗阻的首选有效的姑息性治疗手段。更多还原

【Abstract】 Objective To explore the clinical significance and effect of treating malignant obstruction and stricture of rectum and colon by metallic stent.Methods 47 patients who could not be operated with malignant obstruction and stricture of rectum and colon were treated by Ni-Ti memory alloy mesh stent through anus under X-ray guidance.Results The total 53 Ni-Ti memory alloy mesh stents were used in 47 patients(twice in 6 patients because of the second obstruction).The process was successful once in 43 patients(91.5%)and twice in 4(8.5%).After treatment,the tumor’s fistulas were closed successfully with tectorial stent in 2 cases.The symptoms were alleviated quickly,meteorism disappeared gradually,the half-flow food could be taken and geting well generally in all patients.The survival rate of 6 months was 29.8%(14/47),over 6 months was 70.2%(33/47)and 2 patients are still alive now(followed up over 13 months).Conclusion The way with metallic stents is the first choice in palliative treatment in patients with could not be operated malignant obstructions and stricture of rectum and colon.更多还原
