| Abstract: | "BACKGROUND AND OBJECTIVES: Surgical smoke contains various malodorous and hazardous combustion byproducts. We aimed to analyze hydrocarbons accumulated in the abdominal cavity during laparoscopic gynecologic surgery and determine the efficiency of a built-in-filter port. METHODS: We prospectively followed seven patients with benign uterine pathology. Surgical smoke was generated using laparoscopic or robotic electrocautery. The smoke was collected twice for each patient using a built-in-filter port and a conventional port. The concentrations of volatile organic compounds and aldehydes were determined using gas chromatography with mass spectrometry and high-performance liquid chromatography with ultraviolet visible light detection and compared using the paired-sample Wilcoxon signed-rank test. RESULTS: Five volatile organic compounds and five aldehydes had toxic effects or unpleasant odors. The median concentration of formaldehyde before filtration (0.870 ppm) exceeded the time-weighted average concentration (0.75 ppm) of the Occupational Safety and Health Administration. Built-in-filter ports significantly reduced the concentration of five volatile organic compounds and two aldehydes but not that of formaldehyde, acetaldehyde, and propionaldehyde. Formaldehyde concentration decreased by 50% after filtration but remained above the recommended exposure limit (0.016 ppm) of the National Institute of Occupational Safety and Health. CONCLUSIONS: Surgical smoke in minimally invasive gynecologic procedures contains several hazardous hydrocarbons including formaldehyde. Built-in-filter ports have the potential to reduce the exposure of surgical smoke to surgeons and operating room personnel; nevertheless, development of built-in-filter ports is necessary to improve the filtering efficiency for highly concentrated formaldehydes" |
