Samples were reevaluated by a blinded pathologist to assess the following primary outcome measures: presence and percentage of myometrium on the pathology sample, prevalence of isolated myometrium, and depth of myometrial resection. Data were evaluated using Fisher exact test and Kruskal-Wallis test, followed by multiple comparisons analysis. To maintain a familywise error rate of 5% across all four primary analyses, the Bonferroni correction method was applied.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>Of 458 pathology samples, 21.8% were obtained using hysteroscopic morcellators, 11.1% were obtained with hysteroscopic scissors, and 67.0% were obtained with hysteroscopy with dilation and curettage (D&amp;C).
