Right hemicolectomy has been recognized as a basic surgical procedure in gastrointestinal surgery. Guidelines for the treatment of colorectal cancer were first published in 2005 and defined D3 as a standard lymph node dissection in patients with advanced colorectal cancer. However, strict D3 dissection is not an easy procedure and has technical differences between institutions and instructors. In this article we introduce detailed procedures for right hemicolectomy with antegrade D3 dissection by means of the inside approach which is routinely performed at our institution. We hope this article will be helpful for surgeons who perform operations for right-sided colon cancer.
