Both recommended to stop elective surgery and to take general precautions, but there was little on the pragmatic aspects of surgery. In laparoscopic surgery, an essential part of the technique is the establishment and maintenance of an artificial pneumoperitoneum; with this comes the risk of aerosol exposure for the operation team. Ultrasonic scalpels or electrical equipment commonly used in laparoscopic surgery can easily produce large amounts of surgical smoke, and in particular, the low-temperature aerosol from ultrasonic scalpels cannot effectively deactivate the cellular components of virus in patients. In previous studies, activated corynebacterium, papillomavirus and H.I.V. have been detected in surgical smoke (2) (3) (4) and several doctors contracted a rare papillomavirus (5) suspected to be connected to surgical smoke exposure. The risk of 2019-ncov infection aerosol should not be any exception. One study found that after using electrical or ultrasonic equipment for 10 minutes, the particle concentration of the smoke in laparoscopic surgery was significantly higher than that in traditional open surgery (6) . The reason may be that due to the low gas mobility in the pneumoperitoneum, the aerosol formed during the operation tends to concentrate in the abdominal cavity. Sudden release of trocar valves, non-air-tight exchange of instruments or even small abdominal extraction incisions can potentially expose the health care team to the pneumoperitoneum aerosol; the risk is definitely higher in laparoscopic than in traditional open surgery. This outbreak thus poses a great challenge to the clinical work of surgeons who practice MIS.

Even if all elective surgery has been curtailed if not stopped in countries of the current pandemic, the risk is present for patients who require emergency surgery or operations for malignancy, and above all, for the surgeons and operating room staff who undertake these operations. We would like to share the following, based on our recent experience in Shanghai and Milan. 1) General protection: all surgery patients must complete preoperative health screening, whether they are symptomatic or not. As operating staffs might become infected, and therefore reduced in number, all medical personnel have to comply with the tertiary protection regulations (8, 9) .
