Mean Operative Time (min) –62 ESGE STEP-W T 0 = 11 = 5:4 Group I = 50 = 8:2 T 1 = 32 = 9:1 Group II = 12 = 23:2 (p<0,001) T 2 = 19 = 18:1 (p=0,02) www.ginendo.com Hysteroscopic Myomectomy Lasmar

% Complete Hysteroscopic Myomectomy - 62 ESGE STEP-W T 0 = 11/11 (100%) Group I = 50/50 (100%) T 1 = 31/32 (97%) Group II= 07/12 (58%) (p<0,001) T 2 = 15/19 (79%) (p=0,07) www.ginendo.com Hysteroscopic Myomectomy Lasmar
