Background and aim: Eating disorders, such as BED, and assessment of abnormal body image are routinely investigated, in clinical settings, with Binge Eating Scales (BES) and Body Uneasiness Test (BUT). This study aims at evaluating if BES and BUT questionnaires are predictive of the efficacy of bariatric treatment with BIB. Material and methods: 47 obese patients (39 females; mean age = 36, range 18-59; mean BMI = 41.6, range 31-71) who underwent bariatric treatment with BIB have been evaluated with BES and BUT questionnaires, before the insertion of the BIB (t0) and after 6 months at the moment of the removal (t6). Patients were divided in two groups: one with BMI reduction <12% (group A) and the other with BMI reduction =12% (group B).Group A and B were compared according to the results of BES and BUT questionnaires, in order to assess a statistically significant difference (95% Confidence Interval, p<0.05), before and after bariatric treatment. Results: Group A was composed of 24 patients (mean BMI reduction (3.1±1.9 SD), while group B was composed of 23 (mean BMI reduction 6.8±1.4 SD). At the time t0 there was no difference in the prevalence of BED estimated with BES (4.2% vs 8.7%, in group A and B respectively, (p = ns), whereas at the time t6, BES questionnaire showed a statistically significant difference between group A and B (34%; 95%CI: 21%-44% vs 8,7%; 95%CI: 2%-17%; p < 0,05) and with both groups at the time t0. At the time t0, BUT questionnaire resulted normal in 21% vs 13% in group A and B respectively (p = ns), whereas at the time t6 there was a statistically significant difference between the percentage of normal BUT questionnaire in groups A and B (29%; 95%CI: 17%-40% vs 48%; 95%CI: 34%-59%; p < 0,05) and with both groups at the time t0. Conclusions: Obese patients with BED achieve fewer results with BIB as bariatric treatment. As expected, patients with better BMI % reduction perceive a diminished uneasiness of their body image. However pre-procedural assessment with these tests is not completely useful in order to diagnose BED in these patients, whose identification demands a specialist psychological appraisal.

Abstract
Background and aim: Eating disorders, such as BED, and assessment of abnormal body image are routinely investigated, in clinical settings, with Binge Eating Scales (BES) and Body Uneasiness Test (BUT). This study aims at evaluating if BES and BUT questionnaires are predictive of the efficacy of bariatric treatment with BIB. Material and methods: 47 obese patients (39 females; mean age = 36, range 18-59; mean BMI = 41.6, range 31-71) who underwent bariatric treatment with BIB have been evaluated with BES and BUT questionnaires, before the insertion of the BIB (t0) and after 6 months at the moment of the removal (t6). Patients were divided in two groups: one with BMI reduction <12% (group A) and the other with BMI reduction =12% (group B).Group A and B were compared according to the results of BES and BUT questionnaires, in order to assess a statistically significant difference (95% Confidence Interval, p<0.05), before and after bariatric treatment. Results: Group A was composed of 24 patients (mean BMI reduction (3.1±1.9 SD), while group B was composed of 23 (mean BMI reduction 6.8±1.4 SD). At the time t0 there was no difference in the prevalence of BED estimated with BES (4.2% vs 8.7%, in group A and B respectively, (p = ns), whereas at the time t6, BES questionnaire showed a statistically significant difference between group A and B (34%; 95%CI: 21%-44% vs 8,7%; 95%CI: 2%-17%; p < 0,05) and with both groups at the time t0. At the time t0, BUT questionnaire resulted normal in 21% vs 13% in group A and B respectively (p = ns), whereas at the time t6 there was a statistically significant difference between the percentage of normal BUT questionnaire in groups A and B (29%; 95%CI: 17%-40% vs 48%; 95%CI: 34%-59%; p < 0,05) and with both groups at the time t0. Conclusions: Obese patients with BED achieve fewer results with BIB as bariatric treatment. As expected, patients with better BMI % reduction perceive a diminished uneasiness of their body image.
