Perioperative outcomes of total laparoendoscopic single-site hysterectomy versus total robotic hysterectomy in endometrial cancer patients: A multicentre study

OBJECTIVE: To compare the peri-operative outcomes between total laparo-endoscopic single-site (LESS) and robotic approaches for the staging and treatment of early stage endometrial cancer patients. METHODS: A multicentre retrospective study involving three Italian gynaecological groups and one American centre. The peri-operative outcomes of LESS and robotic approach were compared in similar groups of patients, with regard to surgical outcomes and intra- and post-operative parameters and complications. RESULTS: During the study period, 75 patients submitted to a total LESS hysterectomy and 75 patients received a total robotic hysterectomy. The median operative time - 122 versus 175 min (p=0.0001) - and the estimated blood loss - 50 versus 80 mL (p=0.03) - were slightly more favourable in the LESS group. The intra-operative complications were equally distributed (p=0.99); in the robotic group there were 4 (5.3%) post-operative grade IIIb complications versus 1 (1.3%) in the LESS group (p=0.172). CONCLUSIONS: The LESS and robotic approaches both appear reasonable and each may have benefits and limitations depending upon the patient population. Further studies are needed to validate these preliminary conclusions
