Cumulative rate of complications by stent type. Cumulative rate of complications was investigated using the Kaplan-Meier method. The rate of complications on day 60 was 45% for PS and 0% for MS. On day 90, it was 60% for PS and 0% for MS. Cumulative rate for complications was significantly lower for MS than for PS. Statistical analysis was performed using the log-rank test. MS, metallic stent; PS, plastic stent. The solid line is the MS group; the wavy line is the PS group.
