Smoke Evacuator Laparoscopic Set-Up: Clearing Smoke Without Losing the Pneumoperitoneum

Why laparoscopic smoke is a problem

In a closed abdomen, smoke from monopolar, bipolar or ultrasonic devices has nowhere to go. It clouds the camera view, so the team often vents gas through a port, which releases the plume next to the staff. Repeated venting also disturbs the insufflation pressure and prolongs the procedure. For the health background see our overview of surgical smoke hazards.

The aim is therefore twofold: keep the view clear and stop the plume from reaching the room.

Passive versus active evacuation

Passive evacuation means opening a port or valve so that pressure pushes smoke out through tubing, ideally into a filter. It is simple, but flow is limited and the pneumoperitoneum falls when the valve is open. Active evacuation uses a smoke evacuator that draws gas through a filtered line, often combined with an insufflator that compensates for the loss.

Active evacuation is faster and cleaner when the equipment is designed for it. The BOWA SHE SHA supplies single-use laparoscopy hoses, and its four-stage filter with ULPA-15 and activated carbon cleans the gas before it enters the room. The ATMOS MEDAP FUMOVAC 700 has inlets of 22, 9.5 and 6.4 mm, so a thin laparoscopic line can be connected directly.

• Passive: simple, low flow, pressure loss
• Active: controlled flow through a filter
• Filtered ports and dedicated insufflator lines can reduce loss
• Always use a filter before the gas leaves the abdominal line

Step-by-step set-up

First, choose the route for evacuation: a dedicated filtered port, an integrated insufflation and evacuation device or a spare port with a laparoscopy hose. Second, connect the hose to a filter-equipped evacuator, checking that the connection is airtight. Third, set the suction to the lowest level that clears the smoke, because strong suction can collapse the pneumoperitoneum.

Fourth, coordinate with the insufflator so that the pressure is replaced as gas is removed. Fifth, activate suction when energy is used and stop when it is not: the SHE SHA can start automatically through a sensor, with a foot switch for manual control, and with ARC generators activation can run via a connecting cable.

Safety points and common mistakes

Do not vent unfiltered gas at the end of a case or when changing ports. Capture and filter it. Avoid long, kinked lines which reduce flow, and never reuse single-use hoses. Do not set suction too high near the camera or fragile tissue.

Check compatibility between hose, port and evacuator before the list starts. Mixed-brand connections are a frequent source of leaks. Our guide to smoke evacuator filters explains how to track filter life, and our article on electrosurgery safety in laparoscopy covers the associated energy-device risks.

Equipment choice and training

When selecting equipment, compare noise (both the SHE SHA and FUMOVAC 700 are stated at 55 dBA/dB(A)), the practicality of hose connections and the ability to run quietly for a long case. Review the BOWA SHE SHA and ATMOS FUMOVAC 700 with your surgeons, then train the circulating nurse on set-up and troubleshooting.
