The aim of this observational study is to define national reference values, according to the achievable benchmarks of care method (ABCâ„¢), for laparoscopic bariatric surgery in Sweden. The primary outcome is to identify the best possible, yet achievable, results during and after bariatric surgery. The second outcome to investigate if there are risk groups for complications, and if so perform risk-adjusted benchmark-calculations.
The data source will be the Scandinavian Obesity Surgery Registry (SOReg), a prospective quality registry for obesity surgery. The time frame will be 2012-2021. The techniques to be investigated are laparoscopic roux-en-y gastric bypass and laparoscopic gastric sleeve respectively. Register variables related to surgical quality will be analyzed, and related to risk of peroperative and postoperative complications. The study will analyze data for the time of surgery and up to one year after surgery.
