A laparoscopic surgery through one skin incision by collecting all the ports to one incision is known as a single-port or a single-incision laparoscopic (SLS). Although many names and their acronyms have been proposed, a consensus name for this technique does not exist yet. Trans umbilical endoscopic surgery (TUES), embryonic natural orifices translumenal endoscopic surgery (E-NOTES) and natural orifices trans umbilical surgery (NOTUS) are terms derived from the natural orifices translumenal endoscopic surgery (NOTES) concept. Terms called single-port access (SPA) laparoscopic surgery, one port umbilical surgery (OPUS), single-port surgery (SPS), single-port laparoscopic surgery (SPLS), and single-port incisionless conventional equipment-utilizing surgery (SPICE) have also been used. Laparo-endoscopic single site surgery (LESS) was proposed by the United States multidisciplinary consortium. Needlescopic surgery is defined as a procedure using less than 3-mm laparoscopic instruments. Reduced port laparoscopic surgery (RPLS) is a concept that indicates a laparoscopic surgery aiming at both reducing the number of ports and reducing the diameter of the port. Therefore, both a SLS and a needlescopic surgery are considered to be included into the category of the RPLS.
