Brazilian national bariatric registry - pilot study.

ABSTRACT

INTRODUCTION: Brazil is a world leader in bariatric surgery. However, the actual number of surgeries performed in the country is still unknown. It is necessary to implement an instrument to monitor the quality of care provided. This study evaluated the implementation of a Bariatric Surgery Data Registry in Brazil. METHODOLOGY: the registry was developed with Dendrite Clinical Systems Ltd., with data collected prospectively on an internet-based software. Seven centers were selected based on surgical volume and data entry commitment. The project covered three years after system implementation. RESULTS: 1,363 procedures performed by 17 surgeons were included. Most patients were female (67.2%), with average age of 39 years old and average baseline BMI of 41.5kg/m2. Diabetes mellitus was present in 34.5%, and hypertension in 40.1%. Roux-en-Y gastric bypass was performed in 79.3%, 95.5% by laparoscopy. There was one in-hospital death of cardiovascular cause. The average hospital stay was 2.03 days. The surgery-related complication rate was 0.97% in the first month, with three reoperations. Short-term follow-up was recorded in 75.6% and one-year follow-up in 21.64%. Total body weight loss was 10% in 30 days, rising to 33.3% after one year, with no difference between surgical techniques. CONCLUSIONS: the population profile was in accordance with the global registry of the International Federation for the Surgery of Obesity and Metabolic Disorders. The main difficulty encountered was low postoperative data entry. The experience acquired in this project will help advance data collection and knowledge of the safety and effectiveness of bariatric surgery in Brazil.
