COVID-19 infection poses significant risks during surgical interventions. This study suggests that there is low risk of COVID-19 transmission from the peritoneal cavity during the surgery.

Researchers investigated the intraperitoneal presence of SARS-CoV-2 in COVID-19 positive patients. Overall, 65 pregnant women with COVID-19 infection underwent caesarian section. The diagnosis was confirmed either by positive antigen test or by positive RT-PCR assay performed within no more than 13 days prior to the operation.

On the day of the operation, a nasopharyngeal swab was taken, and peritoneal fluid was collected at the beginning of the operation. Both the nasopharyngeal swab and peritoneal fluid samples were tested for SARS-CoV-2.

The SARS-CoV-2 RNA test by nasopharyngeal swab produced positive results in 34 patients. In this group as well as in 31 non-confirmed patients all peritoneal fluid samples tested negative for SARS-CoV-2 RNA.

Conclusively, these results suggest a low risk of COVID-19 transmission from the peritoneal cavity at the time of laparoscopy or laparotomy
