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

backgroundWeight loss surgery (WLS) is neither risk-free nor universally effective. Few studies have examined what proportion of patients regret having undergone WLS.

methodsWe 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).

resultsOf 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.

conclusionFew patients regret undergoing RYGB but 20% regret undergoing gastric banding with weight loss being a major driver.
