  5. 5. Background:This paper presents a means of intra-abdominal transportation without additional laparoscopy ports.Methods:We performed a single incision laparoscopy cholecystectomy using an operative laparoscope with anoperative channel. An alligator clip in tandem with a neodymium magnet was introduced in theabdomen and placed on the target. A double tether alligator (Secured Independent Tool) wasintroduced using two 18 gauge IV catheters strategically placed under laparoscopic surveillance. Asuture was threaded through the IV catheter and identified with the endoscope as it entered thecavity. The suture was grasped and withdrawn until exiting via the operative port; this maneuver wasdone twice. Outside the port, the sutures were tied to the Secured Independent Tool. The SecureIndependent Tool was introduced and placed on the target.Results:The magnet was used to hold the fundus of the gallbladder and transport the endobag. The SecuredIndependent Tool was used for exposure, mobilization and transportation of the gallbladder. Noperforation of the gallbladder occurred and all functions were done successfully.Conclusions:Magnet transportation in the anterior peritoneum was unlimited in this case. The strategically placedIV catheters allow for an aerial type of tramway transportation of a target between two points insidethe abdomen.

  14. 14. “Secured Independent Tools (SIT) is changing theLaparoscopy paradigm. “ Laparoscopy SIT1 port per instrument. Multiple instruments per port.Cannulas.  Threads or Cables.The diameter of the port The diameter of the is larger that the cable or thread is instrument. smaller that the instrument.
  15. 15. The intravenous catheter is thread with a 2-0 prolene, which is grasped and withdrawn via a 12 mm port . The end is then tied to an alligator clip. To make a tramway, 2 intravenous catheters must be placed at strategic points.J Laparoendosc Adv Surg Tech A. 2012 May;22(4):397-9.

  19. 19. The first intravenous catheter is placed medially at a strategic point
  20. 20. This is the internal view of the needle and catheter
  21. 21. The Catheter is threaded with a 2-0 prolene suture
  22. 22. The second catheter is placed to allow the tramway to run between thetwo points of entrance
  23. 23. Both sutures were tied to the alligator
  24. 24. The alligator was placed at the base of the gallbladder using thealligator clip applier
  25. 25. Exposure achieved with the SIT tramway
  26. 26. Exposure continues during the procedure
  27. 27. The alligator is moved cephalic and medial
  28. 28. Two means of transportation, the magnet at the fundus and the SIT atthe base of the gallbladder
  29. 29. The magnet was released from the fundus and is now transporting anendoscopic bag
