BACKGROUND: This present study shows the preoperative and postoperative serum gastric, a fundamental hormone in the production of gastric chloridric acid, correlating these findings with postoperative complications, in patients submitted to GVBYR. METHODS: We selected 20 patients with body mass index (BMI) over 40 Kg/m² after a rigorous psychological evaluation. Serum gatrin was measured in the preoperative and postoperative periods. These patients were also submitted to upper gastrointestinal endoscopy with biopsy for histological analysis. RESULTS: There was no statistically significant difference between preoperative and postoperative serum gastrin (p= 0.4281). CONCLUSION: Our results show that GVBYR leads to a digestive tract adaptation after surgery, in order to maintain its physiology, suggesting that this procedure is safe for the treatment of morbid obesity.
