Outcomes of self-expandable metal stent as bridge to surgery versus emergency surgery for left-sided obstructing colon cancer: A retrospective cohort study

BackgroundLong-term outcomes of self-expandable metal stents (SEMSs) as bridges to surgery versus emergency in the treatment left-sided obstructing colon cancer remain unclear.MethodsUsing a nationwide inpatient database Japan, we performed one-to-one propensity score matching compare overall survival, stoma requirement, postoperative complications, and length stay between SEMS groups.ResultsCompared with group, group showed worse survival (hazard ratio, 1.80; 95% confidence interval, 1.07–3.01), higher incidence ileus (8% vs. 4%, P = 0.010), longer (14 12 days, < 0.001), lower requirement (10% 29%, 0.001).ConclusionsSEMSs are associated significantly poorer ileus, stay, than is surgery.
