Clinical and Economic Outcomes in Laparoscopic Sleeve Gastrectomy Versus Roux-en-Y Gastric Bypass Surgery

An Observational Study in Morbidly Obese Patients to Evaluate Laparoscopic Gastric Sleeve Resections and Roux-en-Y Gastric Bypass Surgery in Clinical and Health-Economic Terms

Study objectives:

1. generate local clinical, health-related quality-of-life and health economic data to evaluate the benefits of two types of minimally invasive weight-loss surgery
2. support multi-disciplinary bariatric sites in Germany by providing structured procedure guidelines and training, therefore facilitating procedural adoption, increasing safety and shortening the learning curve for weight-loss surgery.

The objectives of this study are the following: to generate local clinical, health-related quality-of-life and health economic data to evaluate the benefits of two types of minimally invasive weight-loss surgery; and to support multi-disciplinary bariatric sites in Germany by providing structured procedure guidelines and training, therefore facilitating procedural adoption, increasing safety and shortening the learning curve for weight-loss surgery.
