Substantial Decrease in Comorbidity 5 Years After Gastric Bypass: A Population-based Study From the Scandinavian Obesity Surgery Registry.

Objective: To evaluate effect on comorbid disease and weight loss 5 years after Roux-en-Y gastric bypass (RYGB) surgery for morbid obesity in a large nationwide cohort.

Background: The number patients having surgical procedures to treat obesity and obesity-related disease are increasing. Yet, population-based, long-term outcome studies are few.

Formation of the Scandinavian Obesity Surgery Registry, SOReg.

Background: Obesity surgery is expanding, the quality of care is ever more important, and learning curve assessment should be established. A large registry cohort can show long-term effects on obesity and its comorbidities, complications, and long-term side effects of surgery, as well as changes in health-related quality of life (QoL). Sweden is ideally suited to the task of data collection and audit, with universal use of personal identification numbers, nation-wide registries permitting cross-matching to analyze causes of death, in-hospital care, and health-related absenteeism.

Early complications after laparoscopic gastric bypass surgery: results from the Scandinavian Obesity Surgery Registry.

Objective: To identify risk factors for serious and specific early complications of laparoscopic gastric bypass surgery using a large national cohort of patients.

Background: Bariatric procedures are among the most common surgical procedures today. There is, however, still a need to identify preoperative and intraoperative risk factors for serious complications.

Body mass and reflux oesophagitis: an oestrogen-dependent association?

Background: There is widespread belief that obesity is associated with gastro-oesophageal reflux disease, but the scientific evidence is weak and contradictory. Our aim is to evaluate the relation between body mass and reflux oesophagitis.

Methods: A population-based case-control study of endoscopically verified case subjects with reflux oesophagitis, and of randomly selected, control subjects matched for age, sex and area of residence.
