TVS was performed presurgically to evaluate lesion size (craniocaudal\u2013midsagittal length, anteroposterior thickness and transverse diameter), in accordance with the International Deep Endometriosis Analysis (IDEA) group consensus statement, and was compared with PSM. The agreement of lesion dimensions between the two methods was assessed by Bland\u2013Altman plots and limits of agreement and additionally by the intraclass correlation coefficient (ICC) and Pearson's correlation coefficient. Systematic and proportional bias was assessed using the paired <jats:italic>t<\/jats:italic>\u2010test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 207 consecutive women were eligible for inclusion. Forty\u2010one women were excluded, leaving 166 women for final analysis. A total of 123 segmental resections and 46 discoid resections were performed (both procedures were performed in three women). The mean difference between TVS and PSM was 0.90 (95%\u2009CI, 0.85\u20130.95)\u00a0mm for lesion length measurements, 1.03 (95%\u2009CI, 0.98\u20131.09)\u00a0mm for lesion thickness measurements and 0.84 (95%\u2009CI, 0.79\u20130.89)\u00a0mm for transverse diameter measurements. Bland\u2013Altman analysis demonstrated good agreement between the two methods for measurements of lesion length. Furthermore, there was good reliability and correlation between TVS and PSM for lesion length measurements, as demonstrated by an ICC of 0.82 (95%\u2009CI, 0.75\u20130.87) and Pearson's correlation coefficient of 0.72 (95%\u2009CI, 0.62\u20130.80), moderate\u2010to\u2010good reliability and correlation for lesion thickness measurements, with an ICC of 0.76 (95%\u2009CI, 0.67\u20130.82) and Pearson's correlation coefficient of 0.61 (95%\u2009CI, 0.51\u20130.70), and poor\u2010to\u2010moderate reliability and correlation for transverse  diameter measurements, with an ICC of 0.58 (95%\u2009CI, 0.39\u20130.71) and Pearson's correlation coefficient of 0.46 (95%\u2009CI, 0.33\u20130.58).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Preoperative TVS determines accurately rectosigmoid DE lesion length.
