Abstract

In Brief Objectives: To compare the long-term benefit of gastric bypass [Roux-en-Y gastric bypass (RYGB)] versus adjustable gastric banding (AGB) on nonalcoholic fatty liver disease (NAFLD) in severely obese patients. Background: NAFLD improves after weight loss surgery, but no histological study has compared the effects of the various bariatric interventions. Methods: Participants consisted of 1236 obese patients (body mass index = 48.4 ± 7.6 kg/m2), enrolled in a prospective longitudinal study for up to 5 years after RYGB (n = 681) or AGB (n = 555). Liver biopsy samples were available for 1201 patients (97.2% of those at risk) at baseline, 578 patients (47.2%) at 1 year, and 413 patients (68.9%) at 5 years. Results: At baseline, NAFLD was present in 86% patients and categorized as severe [NAFLD activity score (NAS) ≥3] in 22% patients. RYGB patients had a higher body mass index (49.8 ± 8.2 vs 46.8 ± 6.5 kg/m2, P < 0.001) and more severe NAFLD (NAS: 2.0 ± 1.5 vs 1.7 ± 1.4, P = 0.004) than AGB patients. Weight loss at 5 years was 25.5% ± 11.8% after RYGB versus 21.4% ± 12.7% after AGB (P < 0.001). When analyzed with a mixed model, all NAFLD parameters improved after surgery (P < 0.001) and improved significantly more after RYGB than after AGB [steatosis (%): 1 year, 7.9 ± 13.7 vs 17.9 ± 21.5, P < 0.001/5 years, 8.7 ± 7.1 vs 14.5 ± 20.8, P < 0.05; NAS: 1 year, 0.7 ± 1.0 vs 1.1 ± 1.2, P < 0.001/5 years, 0.7 ± 1.2 vs 1.0 ± 1.3, P < 0.05]. In multivariate analysis, the superiority of RYGB was primarily but not entirely explained by weight loss. Conclusions: The improvement of NAFLD was superior after RYGB than after AGB. We enrolled 1236 obese patients in a longitudinal study with sequential liver biopsies before and after gastric bypass [Roux-en-Y gastric bypass (RYGB)] or gastric banding [adjustable gastric banding (AGB)]. Nonalcoholic fatty liver disease improved from baseline to 5 years after both interventions but more significantly after RYGB than after AGB. In multivariate analysis, the superiority of RYGB was primarily but not entirely explained by weight loss.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
