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.
