Robotic-assisted Total Hysterectomy with Low Pneumoperitoneal Pressure (6 Mmhg) and Use of Surgical Plume Evacuator System to Minimize Potential Airborne Particles According to the Joint Statement on Minimally Invasive Gynecologic Surgery During the COVID-19 Pandemic: A Case Report from Japan

We presented a case of uncontrolled genital bleeding caused by subserosal fibroid and treated by robotic-assisted hysterectomy during the coronavirus disease 2019 (COVID-19) pandemic. A 49-year-old woman had severe anemia with hypermenorrhea due to submucosal fibroid. Hysterectomy was deemed necessary to control genital bleeding. However, at that time, the number of confirmed COVID-19 cases has been increasing in Japan. Serious concerns have been raised about the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) dissemination during minimally invasive surgery due to pneumoperitoneum-associated aerosolization of particles. We tried to prevent the spread of surgical plume by performing surgery under low pneumoperitoneal pressure at 6 mmHg and by using an evacuation/filtration system. As a result, we successfully performed robotic-assisted hysterectomy with minimized risk of spreading surgical plume-containing aerosol particles into the operating room. It is essential to follow the guidelines issued by the relevant societies and act accordingly to reduce the risk of SARS-CoV-2 infection in medical settings while performing surgery. We hope that our experience will help prevent secondary cases of future SARS-CoV-2 infections.
