The purpose of this project is to study the composition, hazard, and protection of smoke from endoscopic gastrointestinal surgery. The study is a single-center, prospective, randomized, controlled, cohort study. The investigators plan to enroll 80 patients who undergo endoscopic gastrointestinal surgery and 10 medical staff participating in surgery in the gastrointestinal endoscopy room of the First Affiliated Hospital of Xi'an Jiao Tong University. The investigators will randomize the included study subjects. The investigators will monitore smoke and try to remove the smoke with an air sterilizer in the Air sterilizer group. The control group was monitored for smoke without any intervention. The primary endpoint is concentration of PM2.5 in smoke from endoscopic gastrointestinal surgery, the risk factors, and the effect of air sterilizer on its removal. The secondary endpoint is the concentration of PM1.0, PM10, formaldehyde, Total Volatile Organic Compounds, CO, and CO2 in smoke from endoscopic gastrointestinal surgery, the risk factors, and the effect of air sterilizer on its removal. Other exploratory objectives include the hazards of smoke to staff in the gastrointestinal endoscopy room, and the viral content of smoke.
