Correction to: Langenbeck's Archives of Surgery

https://doi.org/10.1007/s00423-022-02536-2

The original version of this article contained a small mistake in the ethics approval section: “This study was approved by the Ethics Committee of the Hyogo Cancer Center and Kobe University.” However, because this study was only used patients’ data of Kobe University, we did not apply for approval of ethics committee of the Hyogo Cancer Center.

The corrected sentence is shown below:

  • “This study was approved by the Ethics Committee of the Kobe University.”

The original article has been corrected.
