Case report of gastrointestinal localization of SARS-CoV-2 and open abdomen technique in an Italian emergency surgery department for gastrointestinal bleeding.

ABSTRACT

This article aims to present the case of a man affected by SARS CoV-2 and to discuss the association between this manifestation, viral infection and Open Abodmen. A 52 years old Caucasian man, affected by SARS CoV-2 infection, was admitted to the Emergency department of Arcispedale Sant'Anna of Ferrara for epigastralgia followed by syncopal episode, vomiting and diarrhea with bloody stools. The next day the patient underwent colonoscopy, which detected an ulceration proximally to the ileocecal valve without active bleeding. Subsequently an initial non-operative management and two pharyngeal swabs negative, for another rectorrhagia and hypotensive episode, underwent emerging surgery and an Open Abdomen was performed. The patient was discharged in 12th post-surgery day without complications. The IHC analysis with anti-SARS-CoV-2 nucleocapsid-protein revealed the presence of viral protein expression in epithelial cell of ulcerated intestinal mucosa. In this case report, we showed the presence of viral inclusion in small intestinal wall after two negative pharyngeal swabs for SARS-CoV-2 RNA. We can also say that the largest amount of viral inclusions was in the tissue of ulceration of the last ileal loop. This case report showed that SARS-CoV-2 can be unseen also after clinical healing. It's probably can be expelled with stools and rectal swabs search for SARS-Cov-2 RNA after pharyngeal swabs could be mandatory for declare heled a patient. Moreover, damage control surgery and Open Abdomen as a surgical technique can be a valid alternative in case of uncertainty of the bleeding source and when a second surgical look is necessary.
