Paediatric inflammatory multisystem syndrome: temporally associated with SARS-CoV-2 (PIMS-TS) - A mimic of intra-abdominal malignancy.

We report the case of a school-aged boy who presented with clinical features suggesting acute appendicitis. However, further imaging which included CT, demonstrated an inflammatory mass involving the transverse colon raising the suspicion of lymphoma. He then developed intestinal obstruction, and in view of the rapid progression of the disease, he was thought to have non-Hodgkin's lymphoma. He underwent an open excisional biopsy, which revealed a necroinflammatory process and no suggestion of lymphoma or an alternative malignancy or specific diagnosis. His steroid treatment was stopped, and he made a good recovery postoperatively. Positive COVID-19 antibodies, positive response to steroids, results and clinical features were consistent with paediatric inflammatory multisystem syndrome (PIMS-TS), with extensive investigation not offering an alternative diagnosis.While PIMS-TS is a relatively new entity, we believe that this case highlights the importance of it being considered a differential diagnosis of a child presenting with an inflammatory mass.

Pediatric Surgery during the COVID-19 Pandemic: An International Survey of Current Practice.

INTRODUCTION: Understanding the challenges experienced by pediatric surgeons in the early phases of the pandemic may help identify key issues and focus research. MATERIALS AND METHODS: Two pediatric surgeons from each of the 10 countries most affected by COVID-19 were surveyed over a 10-day period. Data were obtained regarding service provision, infection control, specific surgical conditions, and the surgical workforce. RESULTS: Twenty pediatric surgeons responded. All centers had postponed non-emergency surgery and clinics for nonurgent conditions with virtual consultations being undertaken in 90% of centers. A majority (65%) of centers had not yet knowingly operated on a positive patient. Minimal access surgery was performed in 75% centers but a further 75% had reduced or stopped upper gastrointestinal endoscopy. The management of simple appendicitis was unchanged in 70% centers, patients with intussusception were being referred for radiological reduction in all centers and definitive pull-through surgery for Hirschsprung patients was performed by 95% where washouts were successful. Timing of surgery for reducible neonatal inguinal hernias had changed in 55% of centers and the management of urgent feeding gastrostomy referrals and of inflammatory bowel disease patients failing with biological therapy varied considerably. CONCLUSION: Service provision has been severely affected by COVID-19 leading to an inevitable increase in untreated surgical pathology. Better understanding of extrapulmonary infectivity, the risk of asymptomatic carriage in children, and the reliability of testing for surgical scenarios may allow appropriate use of conventional surgery, including laparoscopy and endoscopy, and rational development of the novel care pathways needed during the pandemic.
