Abstract Objective Laparoscopic approach should be offered for most patients requiring colectomy, as it is a safe procedure, associated with shorter hospitalization, better cosmetic results, and does not affect negatively the oncological outcomes of colon cancer. However, there no consistent data on safety laparoscopic surgery training during residency.
