[The Scandinavian Obesity Surgery Registry - register for quality and research]

The Scandinavian Obesity Surgery Registry (Soreg) was initiated in 2007 in order to track the quality of bariatric surgery in Sweden during a period of rapid expansion. The main focus of Soreg is quality control and a base for research. All surgical units that perform bariatric surgery in Sweden report to Soreg, and to date about 93 000 patients are included in Soreg. The rate of laparoscopic access has increased and has been over 99 percent the last 10 years. The number of complications has continuously decreased, and bariatric surgery in Sweden has results in line with those published from international high-volume centers. About 160 peer-reviewed publications have used data from Soreg, many of them published in high impact journals. Two randomized controlled trials have used Soreg and 20 PhD theses have used data from Soreg. The focus of Soreg has shifted to long-term complications.
