Core Tip

Core tip: Flexibile single-incision surgery (FSIS), one of recent advances in endoscopic surgery, is a promising single-incision approach, which has exploited the advantages of single-incision laparoscopy and narrow sense of natural orifice transluminal endoscopic surgery (NOTES). Compared to NOTES, FSIS uses the navel to facilitate the extraction of the specimen and the umbilical closure is quick and easy. Compared to SILS, FSIS does not need any specialized device for the entry ports. Furthermore, water-jet hybrid knife technology enables a quick switch between blunt and sharp dissection. This study assessed the feasibility and safety of endoscopic cholecystectomy using transumbilical approach and water jet hybrid knife technology.
