The authors investigated the predictive value of various parameters such as age, preoperative weight, eating behavior, psychiatric disorders, adverse childhood experiences and self-efficacy with regard to weight loss after gastric restrictive surgery.
After a minimum follow-up of 30 months (median follow-up 50 months; range 30-84 months), a questionnaire concerning extent of, satisfaction with, and consequences of weight loss was mailed to 220 morbidly obese female patients following laparoscopic Swedish adjustable gastric banding (SAGB).
Questionnaires were completed and returned by 140 patients (63%). Average BMI loss was 14.6 kg/m(2). Most patients (85%) were happy with the extent of weight loss. Satisfaction with weight loss showed a significant correlation with extent of weight loss. BMI loss was greatest in the obese with an atypical eating disorder (20.0 kg/m(2)), and BMI loss was least in the obese with no eating-disordered behavior before surgery (13.4 kg/m(2)). Obese patients with two or more psychiatric disorders showed significantly less weight loss than did obese patients with one or no psychiatric disorder (BMI units 10.8 vs 14.0 vs 16.1; P=.047).
The findings indicate a less successful outcome for obese patients with psychiatric disorders (particularly adjustment disorders, depression and/or personality disorders), compared to patients not mentally ill. An eating disorder preceding surgery, however, was not a negative predictor of success following bariatric surgery. To improve outcome of bariatric surgery in obese patients with psychiatric disorders, more individual psychosocial intervention strategies are necessary.

    • "Nevertheless, some controversial findings have also been described. Some studies reported that binge ED patients have more difficulties adapting to restrictive eating behaviour after surgery and therefore are at greater risk of poor surgical outcome (Meany, Conceição, & Mitchell, 2014; Niego et al., 2007), while others found no association (Kinzl et al., 2006; Wadden et al., 2011). There are also studies suggesting that BS has a positive effect on abnormal eating behaviour, including uncontrolled and binge eating, at least in the short term (Wimmelmann et al., 2014). "

    ABSTRACT: Bariatric surgery (BS) has proven to be the most effective treatment for weight loss and for improving comorbidities in severe obesity. A comprehensive psychological assessment prior to surgery is proposed to prepare patients for a successful post-surgical outcome. Therefore, the main aim of the present study was to assess psychological and personality predictors of BS outcome. The sample comprised 139 severely obese patients who underwent BS. Assessment measures included the Eating Disorders Inventory-2, the Symptom Checklist-Revised and the Temperament and Character Inventory-Revised. Our results show that favourable BS outcome, after 2 years follow up, was associated with younger age, less depression, moderate anxiety symptoms and high cooperativeness levels. Likewise, metabolic improvements were found to be linked to younger age and certain psychopathological factors. In conclusion, our findings suggest that age, baseline body mass index, psychopathological indexes and personality traits predict successful BS outcome.

    • "Binge eating is one of the most commonly examined disordered eating behaviors amongst individuals pursuing bariatric surgery; however, preoperative binge eating does not necessarily predict poorer outcomes after surgery (Bocchieri-Ricciardi et al., 2006; Burgmer et al., 2005; Kinzl et al., 2006; Legenbauer, Burgmer, Senf, & Herpertz, 2007). Rather, other postoperative eating behaviors and pathology (e.g., loss of control eating and grazing) appear to be better predictors of poorer outcomes. "

    ABSTRACT: Bariatric surgery is increasingly recognized as a highly effective treatment for individuals who are severely obese. Amount of weight loss and resolution of comorbidities surpass those of nonsurgical approaches; however, suboptimal weight loss and weight regain are not uncommon. These outcomes, though not fully understood, are likely at least partially explained by failure to make long-term behavioral and/or cognitive changes. We are unaware of any established clinical tools to guide providers in assessing postoperative behaviors and identifying those who may require specialized treatment. The goal of this paper is to introduce a brief screening tool, The WATCH, to help clinicians assess and identify patients who may be at risk for poor or untoward outcomes post bariatric surgery. We first review the literature on postoperative outcomes, including weight loss, resolution of comorbidities, suboptimal outcomes, and development of problematic eating behaviors. We then provide an easily-recalled, five-item tool that assesses outcomes, and discuss patient responses that may necessitate further intervention or referral.

    • "The role of psychological factors in the outcome of bariatric surgery seems inconsistent. Some studies have found people with psychiatric disorders have less bodyweight loss [13], but others find no relationship or even more bodyweight loss [8]. An emphasis on psychological impact in the postoperative follow-up and detection of possible psychological needs or need of support throughout the treatment course are important [14]. "

    ABSTRACT: Background Obese and overweight people have a higher risk of both chronic physical illness and mental illness. Obesity is reported to be positively associated with psychiatric disorders, especially in people who seek obesity treatment. At the same time, obesity treatment may be influenced by psychological factors or personality characteristics. This study aimed to understand the prevalence of mental disorders among ethnic Chinese who sought obesity treatment. Methods Subjects were retrospectively recruited from an obesity treatment center in Taiwan. The obesity treatments included bariatric surgery and non-surgery treatment. All subjects underwent a standardized clinical evaluation with two questionnaires and a psychiatric referral when needed. The psychiatric diagnosis was made thorough psychiatric clinic interviews using the SCID. A total of 841 patients were recruited. We compared the difference in psychiatric disorder prevalence between patients with surgical and non-surgical treatment. Results Of the 841 patients, 42% had at least one psychiatric disorder. Mood disorders, anxiety disorders and eating disorders were the most prevalent categories of psychiatric disorders. Females had more mood disorders and eating disorders than males. The surgical group had more binge-eating disorder, adjustment disorder, and sleep disorders than the non-surgical group. Conclusion A high prevalence of psychiatric disorders was found among ethnic Chinese seeking obesity treatment. This is consistent with study results in the US and Europe.
