Abstract
Erich Mühe performed the first laparoscopic cholecystectomy using his unique device, "Gallscope" in 1985. Dr. Mühe happened to perform single port surgery as sell. The first report of single port laparoscopic cholecystectomy, reducing the number of incision and size intentionally, was performed by Dr. Navarra in 1997. This brand new concept of laparoscopic surgery has not spread immediately, because of its technical difficulty. However, improving of surgeons' skill and innovation of new devices have made easier and become feasible. Some Japanese endoscopic surgeons set up the society for single incision endoscopic surgery in order to penetrate this operation method safely and securely. The technique of single port cholecystectomy has been standardized. The surgeons can choose variety of devices to perform the operation confirming the critical view of safety. Benefit of the single port surgery is only cosmetic in the present circumstances. The single port surgery is expected to have further benefits.
