Core Tip

Core tip: Though single-incision laparoscopic surgery has been applied in various fields worldwide, the reports on the single-incision laparoscopic common bile duct exploration (SIL-CBDE) are very limited, possibly due to technical difficulties. In this study, we were intended to overcome these difficulties by using additional 2-mm needlscopic grasper. This grasper is separately entered into the right abdomen by a puncture, and helps to form a stable trangulation with the transumbilically placed instruments. Our SIL-CBDE resulted in comparable surgical outcomes as conventional laparoscopic CBDE, indicating that the nSIL-CBDE is not only cosmetically acceptable but also provides both operative safety and feasibility.
