BARIATRIC SURGERY AND BINGE EATING DISORDER: SHOULD SURGEONS CARE ABOUT IT? A LITERATURE REVIEW OF PREVALENCE AND ASSESSMENT TOOLS.

Study heterogeneity accounted for the variability of the results from different centers and methodological flaws such as insufficient sample size and selection bias impaired the evidence on the magnitude of BED in surgical settings. For the sake of comparability and generalizability of the findings in future studies, researchers must recruit representative samples of treatment-seeking candidates for bariatric surgery and systematically apply standard instruments for the assessment of BED.
