Introduction: Up to 30 % of patients undergoing bariatric surgery are dissatisfied with treatment outcomes in the long-term. The aim of this study was to examine overall satisfaction with treatment five years after bariatric surgery and its association with body mass index (BMI) and health-related quality of life (HRQOL). Methods: Patients were surveyed five years after bariatric surgery; 108 patients had Duodenal Switch (DS) and 153 patients had Laparoscopic Sleeve Gastrectomy (LSG). The main outcome was overall treatment satisfaction, assessed by a single question and analyzed by multiple logistic regression. Estimates for continuous independent variables represent the odds ratios (OR) for a 2-standard deviation difference. Results: Five years after surgery, 82.4 % of the patients were very satisfied or satisfied, whereas 17.6 % were unsure or dissatisfied. The following variables assessed at five years were associated with being dissatisfied/unsure: a higher BMI (OR = 6.1, 95% CI = 2.7-14.0, p < 0.001), reduced obesity-specific HRQOL (OR = 3.0, 95% CI = 1.1-7.8, p = 0.03), and reduced mental HRQOL (OR = 0.3, 95% CI = 0.1-0.8, p = 0.02). We also found that a higher proportion of patients who underwent LSG, compared to DS, reported being dissatisfied/unsure (OR = 3.3, 95% CI = 1.3-8.8, p = 0.01). Conclusion: Reduced mental HRQOL and obesity-related HRQOL, as well as higher BMI, were associated with less satisfaction with overall treatment outcomes five years after bariatric surgery. Differences in overall treatment satisfaction by type of operation warrant further investigation.
