Fig. 1. (A) Fluoroscopy time (min) for colonic stenting procedures. (B) Radiation exposure measured during the study (kerma-area product in μGy*m2).

Fig. 2. Kaplan-Meier curves between patient mortality (red line) and freedom from intestinal obstruction (blue line) were not significantly different, i.e. patients died with a patent stent (log-rank Mantel-Cox test: chi-square, 0.5654; p=0.4521).
