Efficacy Study to Evaluate Laparoscopic Fascial Closure Device
Pivotal Study to Evaluate the Efficacy of a Laparoscopic Port Closure Device
Study Overview
Detailed Description
For the patients enrolling in this study, preoperative and postoperative care will be exactly the same. The operative procedure will also be very similar with the only modification being in the way the ports are closed at the end of the surgery and the fact that all ports 11mm or greater will be closed (instead of leaving 11 or 12mm ports to be closed at the discretion of the surgeon). Instead of using a suture-passer to place the suture through the fascia, the surgeon will use the new instrument to drive the suture into the tissue under direct visualization through the umbilical port camera. The same instrument but with new sutures will be used for each of the interrupted stitches that are usually placed to close the port.
The instrument that has been developed by some of the investigators is a 10mm elongated device that can easily be inserted into the port or fascial opening. If inserted through the port, the trocar can then be slid over the instrument to remove the trocar without losing pneumoperitoneum. The instrument has two opposing wings that will open once placed beyond the fascial opening. As the surgeon pulls up on the device, the wings open sliding along the fascia and pushing away any intra-abdominal contents that may be close to the instrument. Once the surgeon assures under direct visualization with the camera that the wings are open at both sides of the wound and that all intra-abdominal contents are out of the way (just as the surgeon would with the standard technique), he or she pushes a plunger that drives two flexible nitinol needles from the shaft of the instrument, through the fascia, and into the wings. The needles will be received in the wings by a set of couplers attached to the same suture that would be used otherwise (#0 Vycril). The surgeon then releases the wings and pulls out the device, leaving a looped suture placed around the opening. The surgeon can then tie the sutures as he or she would normally do on the standard procedure. At any time, the surgeon can reposition or remove the instrument without placing the sutures. The procedure may be repeated as many times as the surgeon considers necessary (usually 1 to close the 11 or 12mm fascial ports and 2 or 3 to close the 25mm fascial port).
