Abstract
BACKGROUND: The process of reintroducing bariatric surgery to our communities in a COVID-19 environment was particular to each country. Furthermore, no clear recommendation was made for patients with a previous COVID-19 infection and a favorable outcome who were seeking bariatric surgery. OBJECTIVES: To analyze the risks of specific complications for patients with previous COVID-19 infection who were admitted for bariatric surgery. SETTING: Eight high-volume private centers from 5 countries. METHODS: All patients with morbid obesity and previous COVID-19 infection admitted for bariatric surgery were included in the current study. Patients were enrolled from 8 centers and 5 countries, and their electronic health data were reviewed retrospectively. The primary outcome was to identify early (<30 d) specific complications related to COVID-19 infection following bariatric surgery, and the secondary outcome was to analyze additional factors from work-ups that could prevent complications. RESULTS: Thirty-five patients with a mean age of 40 years (range, 21-68 yr) and a mean body mass index of 44.3 kg/m(2) (±7.4 kg/m(2)) with previous COVID-19 infection underwent different bariatric procedures: 23 cases of sleeve (65.7 %), 7 cases of bypass, and 5 other cases. The symptomatology of the previous COVID-19 infection varied: 15 patients had no symptoms, 12 had fever and respiratory signs, 5 had only fever, 2 had digestive symptoms, and 1 had isolated respiratory signs. Only 5 patients (14.2 %) were hospitalized for COVID-19 infection, for a mean period of 8.8 days (range, 6-15 d). One patient was admitted to an intensive care unit and needed invasive mechanical ventilation. The mean interval time from COVID-19 infection to bariatric surgery was 11.3 weeks (3-34 wk). The mean hospital stay was 1.7 days (±1 d), and all patients were clinically evaluated 1 month following the bariatric procedure. There were 2 readmissions and 1 case of complication: that case was of a gastric leak treated with laparoscopic drainage and a repeated pigtail drain, with a favorable outcome. No cases of other specific complications or mortality were recorded. CONCLUSION: Minor and moderate COVID-19 infections, especially the forms not complicated with invasive mechanical ventilation, should not preclude the indication for bariatric surgery. In our experience, a prior COVID-19 infection does not induce additional specific complications following bariatric surgery.
