Post‐operative behavioural management in bariatric surgery: a systematic review and meta‐analysis of randomized controlled trials
Abstract
Summary: Recent research has provided evidence that bariatric surgery maximizes long‐term weight loss in patients with severe obesity. However, a substantial number of patients experience poor weight loss outcome and weight regain over time. Post‐operative behavioural management may facilitate long‐term weight control in bariatric surgery population. The objective of this systematic review and meta‐analysis was to determine the effects of post‐operative behavioural management on weight loss following bariatric surgery. Eligible articles were systematically searched in electronic databases. Among the 414 citations, five randomized controlled trials, two prospective and eight retrospective cohort trials analysing behavioural lifestyle interventions and support groups fulfilled the inclusion criteria. The main finding is that behavioural management had a positive effect on weight loss following surgery. In 13 studies, patients receiving behavioural management had greater weight loss than patients receiving usual care or no treatment. A meta‐analysis of five randomized controlled trials suggests greater weight loss in patients with behavioural lifestyle interventions compared with control groups. Post‐operative behavioural management has the potential to facilitate optimal weight loss following bariatric surgery, but conclusions were limited by the small and heterogeneous samples of studies. A more rigorous empirical evaluation on its clinical significance is warranted to improve effectiveness of bariatric surgery.

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.
