Efficacy and safety of robotic complete mesocolic excision: a systematic review.

ABSTRACT

BACKGROUND: Complete mesocolic excision (CME) consists of the complete removal of tumor-bearing soft tissues enveloped by the mesocolic fascia and radical lymphadenectomy at the origin of feeding vessels. We conducted a systematic review, evaluating the efficacy of the robotic CME (RCME) in patients with right-sided colon cancer and presenting the data in comparison to those concerning the open RC (right colectomy) with CME. METHODS: One independent researcher searched the MEDLINE-PubMed database for published and unpublished material. RESULTS: Eighty-three articles were found to refer to CME, 17 of which met the selection criteria following the PRISMA guidelines. All researchers presented short-term outcomes and agreed on the oncologic safety of CME. Different surgical approaches were proposed; however, no significant differences were noticed regarding the peri-operative outcomes. CONCLUSION: Although long-term outcomes are needed to establish it as a standard of care in right-sided colon cancer, RCME is a procedure that gains more and more grounds due to its oncologic safety. The standard medial-to-lateral approach seems to have similar results to other approaches.
