Our first case was a 12-year-old male child admitted with a week of fever, diarrhoea and vomiting. His nasopharyngeal swab tested positive for SARS-CoV-2 by reverse-transcription polymerase chain reaction (RT-PCR). His abdomen was rigid with Blumberg's sign positive. Blood tests showed leucocytosis and elevated serum C reactive protein (CRP). Laparoscopic appendectomy revealed a gangrenous, perforated appendix; during the operation we collected purulent peritoneal fluid which tested positive for SARS-CoV-2 using RT-PCR. On the 1st post-operative day, blood tests showed high levels of D-Dimer, so pulmonary computed tomography scan was performed. Pulmonary embolism was ruled out and only modest bilateral pleural perfusion was reported. On the 8th post-operative day, the patient's clinical situation deteriorated with fever, intense abdominal pain and elevated inflammatory markers. Ultrasound showed a right latero-conal abscess 12 Â 5 cm and a right paravesical abscess 8 Â 4 cm. The 1st operative peritoneal fluid culture grew Bacteroides thetaiotaomicron, Bacteroides fragilis and Escherichia coli, all sensitive to antibiotics (cefoxitin and metronidazole) which we had already started. A second ultrasound after 1 week showed no change in abscess size, so we decided to evacuate them laparoscopically. The second peritoneal fluid collected was
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
