Kaplan-Meir estimation of recurrence-free survival after stent removal in the FC-SEMS (n = 22) and plastic stent group (n = 32). There were no significant differences in recurrence-free survival between the FC-SEMS and plastic stent groups (50.1 (95% CI, 31.2—69.1) vs. 51.7 (95% CI, 28.7—74.7) months, log-rank p = 0.646). Abbreviation: FC-SEMS, fully covered self-expandable metal stent; CI, confidence interval.
