Impact of COVID-19 on the Destiny of Bariatric Patients.

ABSTRACT

Obese patients reported worse outcomes of COVID-19 related to prothrombotic and low-grade inflammation status. During the SARS-CoV-2 outbreak, all non-elective surgeries were postponed, including bariatric surgery (BS). This umbrella review wants to underline obesity as a condition provoking low-grade chronic inflammation, and increasing severe COVID-19 risk; to relaunch the prioritization of BS. The literature search was conducted in March 2022 via Pubmed (MEDLINE) and focused on reviews, systematic reviews, and meta-analyses published in peer-reviewed journals. Terms "bariatric surgery" OR "obesity surgery" OR "metabolic surgery" were analyzed with "COVID-19" OR "SARS-CoV-2" using the AND modifier. Only 13 studies of the 406 screened met the objective. The procrastination of BS over the past two years determined a delay in obesity treatment and severe consequences. The COVID-19 pandemic has had a huge impact on economic costs. Although BS has high costs, a lifetime cost advantage over conventional weight loss methods was demonstrated. As the pandemic continues, health policies must recognize obesity as a disease-predisposing factor for SARS-CoV-2 infection, considering COVID-19 as a new comorbidity mitigable by BS. Care pathways for obese patients in COVID/post-COVID era should be revitalized and the concept of elective surgery attributed to BS should be reformulated.
