探讨支架和梗阻导管治疗左半大肠癌并发肠梗阻患者的疗效以及治疗特点。

选取本院2011年1月至2014年12月收治的左半大肠癌并发肠梗阻患者140例，随机分为支架组和导管组，每组70例。支架组在内镜下放置金属肠道支架减压治疗，导管组在肠镜及X线辅助下采用经肛放置肠梗阻导管治疗。梗阻消失后对患者实施一期肿瘤根治性切除手术。比较两组患者梗阻缓解手术情况、梗阻改善情况以及一期肿瘤根治性切除手术的效果。

导管组中患者梗阻手术成功率明显高于支架组（χ²=2.387，P=0.003），操作时间及手术费用明显低于支架组（t=21.754、165.009，均P<0.01）；导管组中患者腹痛腹胀缓解时间明显长于支架组（t=18.017，P<0.01）；两组患者术后排气时间、术后禁食时间以及住院时间差异无统计学意义（t=1.640、1.314、1.880，均P>0.05）。随访期间两组患者并发症的发生率差异无统计学意义（χ²=0.624，P=0.430）。

采用金属肠道支架治疗左半大肠癌并发肠梗阻患者腹痛腹胀缓解快，而采用经肛放置肠梗阻导管手术成功率高，复发率低，所需费用低且操作时间短。

To investigate the treatment of left colonic cancer patients complicated with intestinal obstruction.

One hundred and forty left colonic cancer patients complicated with intestinal obstruction were selected from Januray 2011 to December 2014, and were randomly divided into the stent group (treated with metallic stent assisted by endoscopy and X-ray) and the catheter group (treated with transanal ileus tube assisted by endoscopy and X-ray) , with 70 cases in each group. The relief of obstruction for radical resection, improvement of obstruction, and effect of radical excision surgery between the two groups were compared.

The surgical success rate of catheter obstruction was higher than that in the stent group (χ²=2.387, P=0.003) . The operation time and expenditure of the catheter group were significantly lower than the stent group (t=21.754, 165.009, all P<0.01) . The abdominal pain relief time of the catheter group was significantly longer than that of the stent group (t=18.017, P<0.01) . The postoperative exhaustion time, postoperative fasting time and hospitalization time of the two groups had no significant difference (t=1.640, 1.314, 1.880, all P>0.05) . The difference of the complications of the two groups was not statistically significant during follow-up (χ²=0.624, P=0.430) .

For left colorectal cancer patients complicated with intestinal obstruction, metallic stents treatment can shorten relief time, while obstruction catheter treatment has the advantages of higher success rate, shorter operation time and lower cost.
