Simple radiologic assessment of visceral obesity and prediction of surgical morbidity in endometrial cancer patients undergoing laparoscopic aortic lymphadenectomy: A reliability and accuracy study.

Aim: To evaluate the reliability of sagittal abdominal diameter (SAD)-a surrogate of visceral obesity-in magnetic resonance imaging, and its accuracy to predict the surgical morbidity of aortic lymphadenectomy.

Methods: We conducted a multicenter reliability (phase 1) and accuracy (phase 2) cohort study in three Spanish referral hospitals. We retrospectively analyzed data from the STELLA-2 randomized controlled trial that included high-risk endometrial cancer patients undergoing minimally invasive surgical staging.
