Laparoscopic surgery has become the standard approach for most thoracic, abdominal, and pelvic procedures in adults and children. We now know that laparoscopy has proven benefits; however, at its introduction, laparoscopy was adopted without appropriate clinical evidence to justify the approach as an alternative to open surgery. In continued efforts to increase the benefits of minimally invasive surgery to their patients, surgeons have innovated new techniques to further decrease the impact of the operation on patients. These innovations range from decreasing the size of ports and instruments to the current group of techniques termed "scarless" surgery. In the current era of evidence-based medicine, it is the surgeon's responsibility to prove that the benefits outweigh the risk before new techniques are widely applied to patients. This article seeks to review the history of laparoscopic surgery, apply lessons learned to the evolution of single-incision laparoscopic surgery, and make a statement urging for sound prospective evaluation.
