¹Includes 2 patients with peritoneal dialysis;

²Original paper reported 15.5%, which represented the percentage of perforation per lesion;

³The rate of late bleeding was 33.3% (5/15) in hemodialysis patients and 9.4% (6/64) in non-hemodialysis patients; the difference was significant (P < 0.05). ND: Not described; HR: Heparin replacement.
