To identify the available evidence on aerosol viral transmission risk during minimally invasive surgery (MIS) and evaluate its impact on guidelines development and clinical activity worldwide during the coronavirus disease 2019 (COVID-19) pandemic. ⋯ There seems to be a dissonance between contemporary guidelines and ongoing surgical activity, possibly due to the perceived lack of evidence. Recommendations regarding changes in clinical practice should be based on the best available research evidence and experience. A scoping review of the evidence and an assessment of the benefits and harms together with a survey showed that laparoscopic procedures do not seem to increase the risk of viral transmission. Nevertheless, the few publications and low quality of existing evidence limits the validity of the review.

To assess the risk of viral infection during urological surgeries due to the possible hazards in tissue, blood, urine and aerosolised particles generated during surgery, and thus to understand the risks and make recommendations for clinical practice. ⋯ Whether SARS-CoV-2 can be transmitted by aerosols remains controversial. Irrespective of this, standard surgical masks offer inadequate protection from SARS-CoV-2. Full personal protective equipment, including at least filtering facepiece-2 masks and safety goggles should be used. Aerosolised particles might remain for a long time in the operating theatre and contaminate other surfaces, e.g. floors or computer input devices. Therefore, scrupulous hygiene and disinfection of surfaces must be carried out. To prevent aerosolisation during laparoscopic interventions, the pneumoperitoneum should be evacuated with suction devices. The use of virus-proof high-efficiency particulate air filters is recommended. Local separation of anaesthesia/intubation and the operating theatre can reduce the danger of viral transmission. Lumbar anaesthesia should be considered especially in endourology. Based on current knowledge, COVID-19 is not a contraindication for acute urological surgery. However, if possible, as European guideline committees recommend, non-emergency urological interventions should be postponed until negative SARS-CoV-2 tests become available.

To determine the risk of COVID-19 transmission during minimally invasive surgical (MIS) procedures METHODS: Surgical society statements regarding the risk of COVID transmission during MIS procedures were reviewed. In addition, the available literature on COVID-19 and other viral transmission in CO2 pneumoperitoneum, as well as the presence of virus in the plume created by electrocautery during MIS was reviewed. The society recommendations were compared to the available literature on the topic to create our review and recommendations to mitigate COVID-19 transmission. ⋯ There is no clear evidence of COVID-19 virus in the CO2 used during MIS procedures or in the plume created by electrocautery. Until the presence or absence of COVID-19 viral particles has been clearly established, measures to mitigate CO2 and surgical cautery plume release into the operating room should be performed. Further study on the presence of COVID-19 in MIS pneumoperitoneum and cautery plume is needed.
