Still a number of different concerns arise. The fundamental hypotheses that were at the base of single-port growing interest were that it could improve cosmesis, decrease post-operative pain and therefore probably allow an earlier return to work with in any case a better patient's satisfaction. None of these has been confirmed yet, if they will ever. It is also clear that those who advocate patients' preference as the main reason for proposing single-port techniques forget that patients' preference is deeply influenced by the assumption that these arguments in favor of single-port surgery are correct, despite there is no realistic certainty about it. Some of the major experts in the field of minimally invasive surgery and active researchers in the field of NOTES share the same skeptical opinion about a real benefit of single port techniques application. Dr Ratner for instance states in a recent interview that "...it is not clear to me whether single port laparoscopy would be beneficial compared to traditional laparoscopy"8 .
