To determine the presence of SARS-CoV-2 nucleocapsid proteins in gastric and gallbladder tissues of patients with a history of COVID-19, particularly those with negative PCR results.
Key Findings:
Presence of SARS-CoV-2 nucleocapsid proteins was detected in gastric and gallbladder tissues of some patients, raising concerns about surgical safety.
Patients had a history of gastrointestinal symptoms related to COVID-19.
Negative PCR results at the time of surgery did not rule out the presence of viral antigens in tissues.
Interpretation:
The findings suggest that SARS-CoV-2 may persist in gastrointestinal tissues despite negative PCR results, raising concerns about the safety of bariatric surgeries in previously infected patients.
Limitations:
Small sample size may limit the generalizability of the findings.
The study only included patients with a specific history of COVID-19 and gastrointestinal symptoms, which may introduce selection bias.
Conclusion:
Lingering SARS-CoV-2 in gastric and gallbladder tissues poses potential risks during bariatric surgery, necessitating further research to understand the implications for surgical safety.
