Comparison between single-site and multiport robot-assisted hysterectomy in obese patients with endometrial cancer: An Italian multi-institutional study.

Abstract

The aim of this study is to compare robotic single-site hysterectomy (RSSH) and robotic multiport hysterectomy (RMPH) for endometrial cancer (EC) in obese patients in terms of surgical outcomes. This retrospective study compares RSSH with RMPH in obese patients with EC and FIGO stages I to II divided in three classes according to their body mass index (BMI): class A (30-34.9 kg/m2 ), class B (35-39.9 kg/m2 ), and class C (>40 kg/m2 ). We included 225 patients (RSSH: 76; RMPH: 149). The operative time and estimated blood loss (EBL) were lower in the A class of the RSSH group. The EBL and the conversion rate increased when the BMI increased in the RSSH group. The hospital stay was higher in the A class of the RMPH group. The advantages of RSSH in terms of reduced invasiveness remain true only in the first BMI class, whereas they are lost when the BMI increased.
