To study the use of LPM for uterine fibroid treatment in Japan, we aimed to perform two national cross\u2010sectional surveys comprising multiple questionnaires.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The first survey (2011\u20132013) was conducted in November 2014, and 203 medical institutions responded. The second survey (2017\u20132019) was conducted in December 2020, and 302 medical institutions were investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 72\u2009104 and 120\u2009425 surgeries and 0.04% and 0.05% cases of postoperative malignancy diagnosis were reported in the first and second surveys, respectively. Magnetic resonance imaging was performed in &gt;90% of the cases in the first and second surveys as preoperative examinations. The frequency of LPM at hysterectomy was 8.9% and 4.6% and the frequency of LPM at laparoscopic myomectomy was 80.4% and 54.8% in the first and second surveys, respectively; both the parameters decreased in the second survey.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>It is impossible to completely exclude malignant diseases even if extensive preoperative diagnosis has been done before surgery.
