内镜下金属支架置入治疗幽门及十二指肠恶性梗阻临床分析

Clinical analyses on endoscopic treatment in gastroduodenal malignant obstruction with metallic stent implantation

目的探讨内镜下金属支架置入治疗幽门及十二指肠恶性梗阻的临床价值。方法对2004.3～2011.9经内镜放置金属支架治疗幽门及十二指肠恶性梗阻24例临床资料回顾性分析。结果 24例共放置支架27枚,失败1例,成功23例,成功率(95.83%)。1例不成功因为支架置入器未能进入狭窄部位,22例患者临床症状缓解,临床有效率(91.67%)。4例患者置入2个支架,2例患者支架移位,2例患者肿瘤向上生长。并发症4例,2例移位,2例梗阻,发生率(16.67%)。结论内镜下金属支架置入是治疗幽门及十二指肠恶性梗阻的有效、安全、简单、可行的治疗方法。

Objective To evaluate the clinical application value of endoscopic treatment in gastroduodenal malignant obstruction with metallic stent implantation.Method The clinical data of 24 cases of endoscopic treatment in gastroduodenal malignant obstruction with metallic stent implantation from March 2004 to September 2011 were analyzed retrospectively.Results Twenty-seven metallic stents were placed in all 24 patients.23 successful implantation and 1 failure were abtained and the successful rate was 95.83%.One case of implantation failure were due to the digestive tract too narrow for stent implantation induced by lesions.After treatment clinical symptom remission rate was 91.67%（22/23）.2 stents were implanted in 4 cases,among which 2 cases due to stent displacement and 2 due to neoplasm growth.Postoperative.complications occurred in 4（16.67%） cases,including stent displacement（2/4） and gastrointestinal obstruction（2/4）.Conclusion The endoscopic treatment in gastroduodenal malignant obstruction with metallic stent implantation was effective、safe、simple and feasible.
