Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology
  • Occupational Health

Background:

  • The clinical benefit of automatic smoke evacuation systems in laparoscopic surgery is not well-established due to a lack of objective evaluation.
  • Electrosurgical smoke poses potential health risks to surgical staff and can obscure the surgical field.

Purpose of the Study:

  • To objectively evaluate the efficacy of an automatic smoke evacuation system during laparoscopic surgery.
  • To assess the impact of smoke evacuation on surgical field visibility and the composition of surgical smoke.

Main Methods:

  • A study involving six pigs utilized electrosurgical smoke generation with and without immediate evacuation.
  • Surgical smoke composition was analyzed using mass spectrometry, and intra-abdominal smoke volume was quantified.
  • Laparoscopic field-of-view was subjectively assessed by ten surgeons.

Main Results:

  • The evacuation group demonstrated a significantly better field-of-view compared to the control group (P < 0.05) after high-frequency electrosurgical unit activation.
  • Surgical smoke contained known carcinogens. Intra-abdominal residual smoke volume was significantly lower in the evacuation group for both high-frequency electrosurgical unit and laparosonic coagulating shears use.
  • Evacuation was particularly effective in reducing smoke when burnt tissue was present.

Conclusions:

  • Automatic smoke evacuation systems enhance the surgical field of view during laparoscopic procedures.
  • These systems effectively reduce the volume of residual smoke within the abdominal cavity.
  • Utilizing automatic smoke evacuation minimizes surgical teams' exposure to potentially hazardous smoke compounds.
