Background
In patients with unresectable colorectal cancer (CRC) obstruction, choosing whether to perform self-expandable metal stent (SEMS) or palliative surgery is challenging, especially in those with good performance status. We aimed to compare the long-term outcomes of SEMS with those of palliative surgery in patients with unresectable CRC obstruction.
Methods
This retrospective study comprised 114 patients with unresectable CRC obstruction who underwent SEMS placement (n = 73) or palliative surgery (n = 41). The main outcome measurements were success rate, adverse events, patency, and survival duration.
Results
Early clinical success rates did not differ between SEMS and surgery. However, the rate of late adverse events was significantly higher in the SEMS group (27.4 vs. 9.8 %; P = .005). Patency duration was shorter after SEMS than after surgery (163 vs. 349 days; P < .001), even after additional intervention (202 vs. 349 days; P < .001). The median survival was significantly shorter after SEMS than after surgery (209 vs. 349 days; P = .005). Survival differed between treatments in patients with Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 (P = .016) but not in those with ECOG 2 or 3 (P = .487), and this was confirmed by multivariate analysis, which showed that surgery was a significant favorable predictor of survival for patients with ECOG 0 or 1 (hazard ratio .442; 95 % confidence interval .234–.835; P = .016).
Conclusions
Surgery may be preferable to SEMS for the palliation of unresectable CRC obstruction in patients with good performance status, especially ECOG 0 or 1.
