Diagnosis of Suspected Small Bowel Bleeding by Capsule Endoscopy in Patients with COVID-19

The current study evaluated the application of small-bowel capsule endoscopy (SBCE) in SARS-CoV-2-infected patients with suspected small bowel bleeding. We analyzed the clinical characteristics, SBCE procedures, examination results, and treatment for cases of suspected small bowel bleeding in two patients with critical COVID-19. SBCE showed active spotting bleeding in the jejunum and ileum with no identifiable lesions in case 1, while multiple small bowel ulcers were detected in case 2. Two patients had relevant changes in their management plans and received specific treatment based on SBCE findings. In summary, SBCE proved to be a non-invasive diagnostic tool for critical COVID-19 patients with suspected small bowel bleeding.
