Evaluation of umbilical anatomy via computed tomography prior to single-incision laparoscopy

Laparoscopic surgery performed through a single incision is relatively new. Here, we investigated the importance of radiological anatomical evaluation of the umbilicus prior to such surgery. Umbilical images of 500 patients who underwent computed tomography (CT) in 2019 were evaluated retrospectively, using both transverse and sagittal sections. Spearman rank correlation analysis indicated a significant positive relationship between age and the sagittal and transverse umbilical measurements (all patients: P < .01; men: P = .001; women: P < .01). Mean transverse and sagittal measurements were 5.63 ± 1.9 and 6.2 ± 2.0 mm in women and 5.49 ± 1.9 and 6.2 ± 1.8 mm in men. Umbilical anatomy can be evaluated radiologically as a component of preoperative evaluation.
