Abstract
BackgroundThis study aimed to evaluate the waiting time, safety, and effectiveness of bariatric surgery based on real-world data.MethodsThis is a noninterventional, noncomparative, and retrospective study with 300 morbidly obese patients who had undergone open Roux-en-Y surgery.ResultsThe procedure was found to be very safe, with low rates of overall complications (10.7%). Approximately 48.4% of the patients had reached a BMI <30 mg/kg2 at 12 months after surgery, while 6% were still classified as morbidly obese (BMI >40 mg/kg2). Comorbidity resolution was over 90% for all conditions, except for cardiovascular disease, which showed a 40% resolution. The mean number of drugs taken also decreased at 12 months after surgery.ConclusionsBariatric surgery was found to be effective in weight reduction and in the resolution of comorbidities.
Highlights
Obese people have a higher risk of type 2 diabetes, cardiovascular diseases, hypertension, and several types of cancer, and the higher prevalence of comorbidities is directly connected with increased medical spending
This limits the ability to evaluate the safety and relevant clinical outcomes in Brazil with real-world data. This is especially important given that globally, most real-world data on bariatric surgery is on laparoscopic procedures, while in Brazilian public system, it is performed as an open procedure
Main inclusion criteria were consistent with eligibility criteria described in the Brazilian Public Health Guidelines at the time the study was conducted: age 18–65 years old, BMI ≥40 kg/m2 or BMI ≥35 mg/m2 in combination with at least one severe comorbidity associated with obesity [6], and at least 1 year postprocedure follow-up data
Summary
Obese people have a higher risk of type 2 diabetes, cardiovascular diseases, hypertension, and several types of cancer, and the higher prevalence of comorbidities is directly connected with increased medical spending. Procedure outcomes is available on the National Database for the public healthcare system records, but information regarding waiting time, long-term safety, comorbidity resolution, weight loss, and number of pharmaceutical prescriptions per patient is not available. This limits the ability to evaluate the safety and relevant clinical outcomes in Brazil with real-world data. This is especially important given that globally, most real-world data on bariatric surgery is on laparoscopic procedures, while in Brazilian public system, it is performed as an open procedure. This study aimed to evaluate the waiting time, safety, and effectiveness of bariatric surgery based on realworld data
