New Submucous Fibroids Classification STEP-W classification AAGL 35 th Annual Meeting AAGL 35 th Annual Meeting Lasmar Hysteroscopic Myomectomy

Lasmar Classification (ESGE)  0 - Fibroids totally in cavity  1 - More than 50% in cavity  2 - Less than 50% in cavity Wamsteker K, 1993 Hysteroscopic Myomectomy

Lasmar New Classification Target More Correlation with Difficulty and Complexity of Hysteroscopic Myomectomy

Lasmar New Classification Including more 4 parameters: Penetration Penetration Size Size Topography Topography Extension of the base Extension of the base Wall Wall Hysteroscopic Myomectomy

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) Hysteroscopic Myomectomy Lasmar

Average Fluid Balance (ml) = 62 ESGE STEP-W T 0 = 11 = 56.2 Group I = 50 = 89.8 T 1 = 32 = Group II = 12 = (p=0,02) T 2 = 19 = (p=0,17) 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) Hysteroscopic Myomectomy Lasmar

Conclusion STEP-W Classification has a bigger Correlation with the Difficulty and Complexity of Hysteroscopic Myomectomy
