This is especially relevant for surgery involving electrocautery, lasers or ultrasonic scalpels because viruses (including hepatitis B, hepatitis C and human immunodeficiency virus) spread through gaseous by-products commonly referred to as 'surgical smoke'. Abdominal fluid (ascites), bile, liver and gall bladder samples were collected during emergency cholecystectomy of a critically ill patient suffering from COVID-19. Tracheal secretion and throat swab samples were collected immediately prior to surgery as positive controls. All samples were tested for SARS-CoV-2 by real-time reverse transcriptase polymerase chain reaction (PCR) using validated primers 5 . PCR tests revealed strongly positive results for SARS-CoV-2 RNA in tracheal secretion as well as in throat swab samples, with cycle threshold values of 20 and 25, respectively. The remaining samples all tested negative for SARS-CoV-2 suggesting that the virus does not spread to the abdominal cavity, bile and abdominal organs. A stool sample obtained one day after surgery also tested negative. These preliminary findings suggest that the potential infectious risk for operating theatre staff and surgeons during open and laparoscopic operations in SARS-CoV-2 patients is lower than initially expected 3 .
