Step-by-step single-port retroperitoneal right hemicolectomy with D3-lymph node dissection for right colon cancer.

Minimally invasive right hemicolectomy for colon cancer has demonstrated better outcomes than those of open surgery. However, in certain patients, high body mass index, abdominal adhesions, and concomitant cardiopulmonary disease may limit the use of conventional laparoscopy. The use of the retroperitoneal approach preserves the benefits of the minimally invasive approach and expands the range of surgical options. All major steps were performed without access to the abdominal cavity: mobilization, D3 lymph node dissection and vessels ligation. Supplementary video demonstrates a retroperitoneal approach for right hemicolectomy with D3 lymph node dissection that can solve these challenges.
