Natural orifice versus conventional mini-laparotomy for specimen extraction after reduced-port laparoscopic surgery for colorectal cancer: propensity score-matched comparative study

Abstract

Although reduced port laparoscopic surgery (RPLS), defined as laparoscopic surgery performed with the minimum possible number of ports and/or small-sized ports, is less invasive than conventional laparoscopic surgery by reducing the number of surgical wounds, an extension of the incision is still needed for specimen extraction, which can undermine the merits of RPLS.
