Evaluation of the Radiological Gastric Capacity and Evolution of the BMI 2–3 Years After Sleeve Gastrectomy

摘要

Sleeve gastrectomy is a restrictive procedure for treatment of obese patients with different body mass index (BMI) and presents good results in terms of a reduction of percentage of excess weight loss and BMI. There is no consensus which is the optimal technique regarding to the diameter of the gastric tube, but a capacity of 100–120 ml has been suggested. In this prospective study, we compare the gastric capacity evaluated with barium sulfate or computer-aided tomography (CAT) scan early and 24 months after operation compared to the changes in body weight and BMI reduction in a small group of 15 consecutive patients submitted to sleeve gastrectomy.
