Is it possible to obtain a presurgical Lasmar score for hysteroscopic myomectomy by ultrasound alone?

Objective To determine whether a Lasmar score obtained entirely by the use of two‐dimensional (2D) and three‐dimensional (3D) ultrasound provides results similar to those obtained using the original hysteroscopic technique. Methods This was a prospective study performed on a series of patients presenting with symptomatic submucous fibroids and scheduled for hysteroscopic myomectomy. Ultrasound Lasmar scores were obtained by a single physician, a specialist in ultrasonography, in the luteal phase of the menstrual cycle. 3D images were evaluated by offline examination using multiplanar analysis. Classical Lasmar scores were obtained by a different physician, a specialist in hysteroscopy, during the follicular phase of the subsequent cycle. Surgery was performed by a third physician in the follicular phase who also reported a Lasmar score, which we considered as the gold standard. The concordance between group classifications (I–III, relating to difficulty of hysteroscopic resection) according to the three methods used to obtain the Lasmar score (ultrasound, classical and surgery) was calculated using Cohen's κ statistic. Results Thirty‐four women, with a mean age of 43 ± 4.9 years, were enrolled in the study. Thirty‐six submucous fibroids were identified by both ultrasound and diagnostic hysteroscopy. The mean diameter of fibroids evaluated was 28 ± 13.2 mm. The concordance between the three methods of classifying patients according to Lasmar score was high: classical vs. surgery, κ = 0.88; ultrasound vs. surgery, κ = 0.93; and classical vs. ultrasound, κ = 0.77. Conclusion The Lasmar score can be obtained solely by ultrasound examination performed in the luteal phase of the menstrual cycle, avoiding office hysteroscopy without a loss of diagnostic accuracy.
