Assessment of the clinical and laboratorial profile of patients with obesity and asymptomatic COVID-19 undergoing bariatric surgery in Brazil.

Purpose: to outline the clinical and laboratorial profile of patients with obesity undergoing bariatric surgery who presented positive reverse transcription-polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus-2 (Sars-CoV-2) in the preoperative period without symptoms presentation.

Methods: Case series of 17 patients undergoing bariatric surgery who presented positive RT-PCR for Sars-CoV-2 in the preoperative period, with no reported symptoms. Data collected included demographic characteristics, length of hospital stay, waiting time for surgery, inflammatory markers, serum levels of micronutrients and dengue virus (DENV) serology.

Is COVID-19 Severity Impacted by Bariatric Surgery in the Early Postoperative Period?

Purpose: The aim of this study was to determine the real influence of bariatric surgery on the clinical evolution of patients infected with SARS-Cov-2 in the postoperative period.

Methods: We conducted a retrospective analysis including two groups of patients: those who presented COVID-19 before bariatric surgery and those who presented it within 3 months of postoperative. Primary outcome was related to the severity of COVID-19, measured by the following variables: presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation.
