Retraction: Multi-institutional surgical outcomes of robotic single-port surgery: a Korean experience

Shortly following publication of the manuscript “Multi-institutional surgical outcomes of robotic single-port surgery: a Korean experience” (1) in January 2023, the ACS Editorial Office received notification that ethical approval may not have been obtained from one of the authors’ participating sites. This was later confirmed with the authors, who apologised for the oversight that four of the included patients received their operations at a separate institution, and therefore did not have Institutional Review Board ethics approval for this sub-cohort.

The Annals of Cardiothoracic Surgery maintains the highest quality of publication ethics. We regret to inform readers that this study has been retracted.
