Effect of COVID-19 pandemic on global Bariatric surgery PRActiceS – The COBRAS study

Introduction: There is a paucity of data in scientific literature on the impact of Coronavirus Disease 2019 (COVID-19) pandemic on bariatric surgery. The aim of this study was to evaluate the impact of COVID-19 pandemic on Bariatric Surgery globally. Methods: We conducted a global online survey of bariatric surgeons between 16/04/20 – 15/05/20. The survey was endorsed by five national bariatric surgery societies and circulated amongst their memberships. Authors also shared the link through their personal networks, email groups, and social media. Results: 703 respondents from 77 countries completed the survey. Respondents reported a drop in elective bariatric activity from a median (IQR) of 130 (60–250) procedures in 2019 to a median of 0 (0–2) between16/03/2020 and 15/04/2020 during the pandemic. The corresponding figures for emergency activity were 5 (2–10) and 0 (0–1) respectively. 441 (63%) respondents did not perform any bariatric procedures during this time period. Surgeons reported outcomes of 61 elective bariatric surgical procedures during the pandemic with 13 (21%) needing ventilation and 2 (3.3%) deaths. Of the 13 emergency bariatric procedures reported, 5 (38%) needed ventilation and 4 (31%) died. 90 (13%) surgeons reported having had to perform a bariatric surgical or endoscopic procedure without adequate Personal Protective Equipment. Conclusions: COVID-19 pandemic led to a remarkable decline in global elective and emergency bariatric surgery activity at its beginning. Both elective and emergency procedures performed at this stage of the pandemic had considerable morbidity and mortality.
