Single Incision Laparoscopy Performance and Current Status in Surgical Practice
Abstract
The techniques of single-incision laparoscopic surgery (SILS) is developed and based on that of conventional laparo-endoscopic surgery. At first, surgeons wanted to devise a method for visceral surgery with no incision on body’s surface, which is called natural orifice transluminal endoscopic surgery (NOTES). As early as the 1970s, Dr. Raimund Wittmoser, the “father” of modern thoracoscopic surgery of the autonomic nervous system, used a single-intercostal incision through which he inserted a multifunctional port which contained all the instruments and optics. Another example of SILS in early times is the application of laparoscopic instrumentation to resect lesions in the rectum or sigmoid colon. Using the anus as the portal of entry, trans- anal endoscopic microsurgery (TEMS) employs a specialized multichannel trocar to reach lesions located 8 to 18 cm away from the anal verge. Compared to NOTES, SILS is easier, safer, more applicable and convenient for surgeons to master and the main reason is that physicians, but not surgeons always use endoscopes. However, laparoscope has been a tool for surgeons for a long time.
