目的探讨经结肠镜钳道直视下置入金属支架治疗胃十二指肠恶性梗阻的临床疗效。方法将2010年6月至2015年6月收治的30例行经结肠镜钳道直视下置入金属支架治疗的胃十二指肠恶性梗阻患者作为研究组,另选取同期收治的36例行常规外科手术治疗的患者作为对照组,对比两组的梗阻改善情况。结果研究组患者的金属支架全部置入成功,两组患者的梗阻全部得到了有效缓解。研究组治疗后的狭窄段直径显著大于对照组[(5.43±1.75)cm vs(4.75±1.12)cm,P<0.05],研究组并发症发生率略低于对照组,但差异无统计学意义[(10.00%vs 22.22%,P>0.05)。两组患者的平均生存期比较无明显差异[(24.5±3.6)个月vs(23.9±4.4)个月,P>0.05)。结论对胃十二直肠恶性梗阻患者行经结肠镜钳道直视下置入金属支架治疗,能迅速、有效地解除梗阻,同时还具有可重复性强、操作简单、耐受性好等优点。
Objective To investigate the clinical efficacy of colon stent grafting under direct vision into metal stent in the treatment of malignant gastroduodenal obstruction. Methods Thirty patients with malignant gastroduodenal obstruction underwent colposcopy under direct vision underwent colposcopy were selected as study group from June 2010 to June 2015. Another 36 patients were enrolled in this study. Patients treated with conventional surgery as a control group, compared with two groups of obstruction to improve the situation. Results All metal stent in the study group was successfully inserted, and the obstruction of both groups was effectively relieved. The diameter of the stenosis in the study group was significantly larger than that in the control group [(5.43 ± 1.75) cm vs (4.75 ± 1.12) cm, P <0.05]. The complication rate in the study group was slightly lower than that in the control group, but the difference was not statistically significant [(10.00% vs 22.22%, P> 0.05). There was no significant difference in mean survival between the two groups [(24.5 ± 3.6) months vs (23.9 ± 4.4) months, P> 0.05). Conclusion The patients with malignant gastric gastroduodenal obstruction undergoing colposcopy under direct vision into the metal stent treatment can quickly and effectively relieve the obstruction, but also has the advantages of reproducibility, simple operation, good tolerance and so on.
