title: Optimizing Laparoscopically Extracorporeal Knot Tying Using a Novel Pusher Device.
abstract: The aim of this study was to evaluate the efficacy and feasibility of a novel pusher device for performing extracorporeal knot tying. Each of the 3 laparoscopists randomly performed 10 device-assisted double sheet bends (the device group), ten 4s modified Roeder sliding knots (the sliding group), and 10 laparoscopic traditional extracorporeal static surgeon's knots (the static group). All knots and 5 unknotted threads were measured for strength. The device group had higher knot strength, lower knotting failure rate, and shorter knotting time compared with the sliding group. The knot strengths of the successful knots in the device group were consistent with those obtained in the static group, and higher than the sliding group. Our laparoscopic novel pusher device should be an effective device in assisting knot tying with the advantages of steady and strong knot strength, lower failure rate, and shorter knotting time.
