Self-expanding metallic stents versus surgical intervention as palliative therapy for obstructive colorectal cancer: a meta-analysis. World J Surg 2015; 39: 2037-2044.

Published: 15th December 2015

Authors: Takahashi H, Okabayashi K, Tsuruta M, Hasegawa H, Yahagi M, Kitagawa Y et al.

Conclusion

This review included ten studies. Stents reduced the risk of early complications (odds ratio 0.34, 95 per cent confidence interval 0.2 to 0.58, P<0.01), and the need for a stoma (0.19, 0.12 to 0.28, P<0.01). They increased the risk of perforation (5.25, 2 to 13.8, P<0.01) and late complications (1.94, 0.9 to 4.19, P=0.03). They contributed to improved long term survival (0.46, 0.31 to 0.68, P<0.01).
