Introduction: During laparoscopic surgery, the production of smoke by energized dissecting devices is a problem because it can obstruct the view of the operative field. The products of combustion may also contain hazardous chemicals, such as benzene, toluene, viable cancer cells or viruses. However, these devices, in particular Laparoscopic Coagulation Shears (LCS), are often essential during laparoscopic surgery. We suggest a simple evacuation system to resolve this problem using intravenous tubing. Material and surgical technique:The intravenous tubing is cut diagonally, proximal to the drip chamber and sterile spike. The cut end of the tubing is taped to the shaft near the active blade side on the LCS. The luer-lock side of the tubing is connected to a suction source. The smoke and vapor arising at the dissection point during the use of the LCS are removed by the application of continuous suction to the tubing. Discussion:We describe a method for the efficient evacuation of combustion products generated by the intraoperative use of the LCS using an inexpensive and easily available device.
