Results of bile duct clearance after large-balloon dilation
LBD alone (n= 62) EST plus LBD (n= 69) P value
Diameter of inflated balloon (mm) 15.9 ± 2.3 (12-20) 16.2 ± 2.5 (12-20) 0.444
Complete stone removal irrespective of whether ML was used, no. (%) 60 (96.8) 66 (95.7) 0.738
Complete stone removal without ML, no. (%) 50 (80.6) 51 (73.9) 0.360

LBD: Large-balloon dilation; EST: Endoscopic sphincterotomy; ML: Mechanical lithotripsy.

Continuous variables are expressed as mean ± standard deviation (range).
