| Abstract: | "BACKGROUND: Surgical smoke containing potentially carcinogenic and harmful materials is an inevitable consequence of surgical energy devices, and constitutes a substantial occupational hazard in the operating room. This study aimed to evaluate the efficacy of a built-in-filter trocar in eliminating hazardous surgical smoke during laparoscopic and robotic rectal surgery. METHODS: Ten patients who underwent rectal cancer resection were enrolled. Five patients underwent surgery utilizing a nonfiltered trocar, and the remaining 5 utilized a built-in-filter trocar. Gas samples were aspirated from the peritoneal cavity over 30 minutes of electrocauterization and collected in a Tedlar bag. Concentrations of surgical smoke were measured using ultraperformance liquid chromatography and gas chromatography. RESULTS: Eleven hazardous chemical compounds (benzene, toluene, ethylbenzene, xylene, styrene, formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, isovaleraldehyde, and valeraldehyde) were identified in the surgical smoke. With the built-in-filter trocar, removal rates of 69% for benzene (P=0.028), 72% for toluene (P=0.009), 67% for butyraldehyde (P=0.047), 46% for ethylbenzene (P=0.092), 44% for xylene (P=0.086), 35% for styrene (P=0.106), 39% for formaldehyde (P=0.346), and 33% for propionaldehyde (P=0.316) were achieved. CONCLUSIONS: This study confirmed the presence of harmful materials in surgical smoke. Evacuation of surgical smoke through a disposable built-in-filter trocar is a simple and effective way in reducing volatile organic compounds concentrations" |
