Decision Regret up to 4 Years After Gastric Bypass and Gastric Banding.

BACKGROUND: Weight loss surgery (WLS) is neither risk-free nor universally effective. Few studies have examined what proportion of patients regret having undergone WLS. METHODS: We interviewed patients at two WLS centers before and after WLS about weight loss, quality of life/QOL (Impact of Weight on QOL-lite), and decision regret (modified Brehaut Regret scale, range 0-100). We conducted separate multivariable logistic regression models to examine the association between weight loss and ∆QOL scores and having decision regret (score > 50). RESULTS: Of 205 RYGB patients, only 2.2% (year 1) to 5.1% (year 4, n = 134) reported regret scores > 50 over 4 years; 2.0-4.5% did not think they made the right decision; 2.0-4.5% would not undergo WLS again. In contrast, of 188 gastric banding patients (n = 123 at year 4), 8.2-20.3% had regret scores > 50; 5.9-19.5% did not think they made the right decision; 7.1-19.5% would not undergo WLS again. Weight loss and ∆QOL scores were significant correlates of decision regret after banding although weight loss was a stronger correlate with lower model quasi-likelihood under the independence model criterion score. Four years after banding, mean weight loss for patients with regret scores > 50 was 7.4% vs. 21.1% for those with scores < 50; the AOR for regret score > 50 was 0.90 (95% CI 0.87-0.94) for every 1% greater weight loss. Poor sexual function, but not weight loss or other QOL factors, was significantly correlated with decision regret after RYGB. CONCLUSION: Few patients regret undergoing RYGB but 20% regret undergoing gastric banding with weight loss being a major driver.
