“…Of the remaining studies, 21 met the inclusion criteria. Following detailed assessment of the full manuscripts, five studies (2 reviews, 2 with no control groups and 1 with no relevant reported outcomes) were excluded. The remaining 16 publications included four RCTs and 12 cohort studies, of which four 33–35,37 were prospective and eight retrospective.…”

Background The aim was to investigate whether preoperative weight loss results in improved clinical outcomes in surgical patients with clinically significant obesity. Methods This was a systematic review and aggregate data meta‐analysis of RCTs and cohort studies. PubMed, MEDLINE, Embase and CINAHL Plus databases were searched from inception to February 2018. Eligibility criteria were: studies assessing the effect of weight loss interventions (low‐energy diets with or without an exercise component) on clinical outcomes in patients undergoing any surgical procedure. Data on 30‐day or all‐cause in‐hospital mortality were extracted and synthesized in meta‐analyses. Postoperative thromboembolic complications, duration of surgery, infection and duration of hospital stay were also assessed. Results A total of 6060 patients in four RCTs and 12 cohort studies, all from European and North American centres, were identified. Most were in the field of bariatric surgery and all had some methodological limitations. The pooled effect estimate suggested that preoperative weight loss programmes were effective, leading to significant weight reduction compared with controls: mean difference –7·42 (95 per cent c.i. –10·09 to –4·74) kg (P < 0·001). Preoperative weight loss interventions were not associated with a reduction in perioperative mortality (odds ratio 1·41, 95 per cent c.i. 0·24 to 8·40; I2 = 0 per cent, P = 0·66) but the event rate was low. The weight loss groups had shorter hospital stay (by 27 per cent). No differences were found for morbidity. Conclusion This limited preoperative weight loss has advantages but may not alter the postoperative morbidity or mortality risk.

“…Although several studies have analysed preoperative predictors of WL after BS, detecting personality traits, cognitive function, mental health, and binge eating as negative factors (Agüera et al, 2015;García-Ruiz-de-Gordejuela et al, 2017;Wimmelmann, Dela, & Mortensen, 2014), only few studies have explored predictors of poor WL achievement prior to BS. Predictors for poor WL prior to BS include being female and non-Caucasian (Hutcheon, Byham-Gray, Marcus, Scott, & Miller, 2017), a high snacking frequency (Bergh, Lundin Kvalem, Risstad, & Sniehotta, 2016), the presence of depressive symptomatology (Nicolau et al, 2017), and having a number of comorbidities (Bergh, Kvalem, Risstad, Cameron, & Sniehotta, 2015).…”

Introduction Evidence suggests that food addiction (FA) is prevalent among individuals with obesity seeking bariatric surgery (BS), but there is no evidence about whether FA is a predictor of weight loss (WL). We aimed to analyse the prevalence of FA in patients with obesity seeking BS and to examine whether FA could predict WL following dietary intervention before surgery. Method The study included 110 patients with obesity who underwent a dietetic intervention. Assessment included endocrinological variables, a semistructured interview to rule out mental disorders, and Yale Food Addiction Scale version 2.0 (YFAS 2.0). Results In our sample, the prevalence of FA was 26.4%. Those who met YFAS 2.0 criteria showed less WL after dietetic intervention and regain weight during dietary intervention. Conclusions FA appears to be prevalent in obesity. Our findings confirmed a lower WL throughout dietary intervention before surgery in patients who fulfilled baseline criteria for FA. Future interventions should include multidisciplinary intervention to maximize WL before and after BS.

“…The mean interval between indication for surgery and the procedure was long (over 2 years) and the patients experienced 5.7% total body weight loss during this period compared with basal weight or 17.58% of total body weight loss (TBWL). It has been demonstrated that the patients may benefit from close monitoring of weight preoperatively; therefore, our program performs periodic visits while on the wait list, on average one visit quarterly [8]. …”

BackgroundThis study aimed to evaluate the waiting time, safety, and effectiveness of bariatric surgery based on real-world data.MethodsThis is a noninterventional, noncomparative, and retrospective study with 300 morbidly obese patients who had undergone open Roux-en-Y surgery.ResultsThe procedure was found to be very safe, with low rates of overall complications (10.7%). Approximately 48.4% of the patients had reached a BMI <30 mg/kg2 at 12 months after surgery, while 6% were still classified as morbidly obese (BMI >40 mg/kg2). Comorbidity resolution was over 90% for all conditions, except for cardiovascular disease, which showed a 40% resolution. The mean number of drugs taken also decreased at 12 months after surgery.ConclusionsBariatric surgery was found to be effective in weight reduction and in the resolution of comorbidities.
