PREVALÊNCIA DE ANEMIA EM PACIENTES EM PÓS-OPERATÓRIO TARDIO DE BYPASS GÁSTRICO EM UM HOSPITAL UNIVERSITÁRIO

Abstract

Introduction: The number of bariatric surgical procedures performed worldwide has been steadily increasing. According to the American Society for Metabolic and Bariatric Surgery, the Roux-en-Y gastric bypass (RYGB) continues to be the gold standard in relation to other bariatric procedures. Complications after surgical treatment for severe obesity vary according to the procedure performed and can reach up to 40 percent. Clinical follow-up after bariatric surgery has shown a tendency for hematological changes, mainly chronic anemia, as well as nutritional changes. Objectives: To evaluate anemia as a risk factor in the late postoperative period of RYGB, as well as its rates and related factors, and the outcome of adult patients at HUUFMA. Methods: This is an observational, retrospective, cross-sectional study of patients over 18 years of age who underwent RYGB at HUPD-UFMA between January 2020 and July 2022. Data collection was performed through a database of patients followed by the Bariatric Surgery Service. Conclusion: In the present study, a statistically significant difference was observed in micronutrient deficiency anemia (vitamin B12, folic acid, and iron) between the patients evaluated. Multidisciplinary follow-up is the necessary measure for a good clinical outcome, which brings prophylactic and therapeutic benefits, since nutritional deficiencies and surgical success are directly linked to eating behavior and adequate supplementation.
