Effects of Sleeve Gastrectomy on Pelvic Floor Disorders in Female Patients with Severe Obesity: a Prospective Study. Obes Surg 2023; 33:3069-3076. [PMID: 37428362 DOI: 10.1007/s11695-023-06725-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 06/30/2023] [Accepted: 07/06/2023] [Indexed: 07/11/2023]
Abstract
INTRODUCTION Obesity is associated with pelvic floor disorders (PFD). Sleeve gastrectomy (SG) is one of the most effective weight loss methods. Although SG has been found to improve urinary incontinence (UI) and overactive bladder (OAB), its impact on fecal incontinence (FI) remains controversial. MATERIALS AND METHODS This prospective, randomized study involved 60 female patients with severe obesity who were randomly assigned to two groups: the SG group and the diet group. The SG group underwent SG, while the diet group received a low-calorie, low-lipid diet for 6 months. The patients' condition was assessed before and after the study using three questionnaires: the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS), the Overactive Bladder 8-Question Awareness Tool (OAB-V8), and the Wexner Score (CCIS). RESULTS After 6 months, the SG group had a significantly higher percentage of total weight loss (%TWL) compared to the diet group (p<0.01). Both groups showed a decrease in the ICIQ-FLUTS, OAB-V8, and CCIS scores (p<0.05). UI, OAB, and FI improved significantly in the SG group (p<0.05), but no improvement was observed in the diet group (p>0.05). The correlation between %TWL and PFD was statistically significant but weak, with the strongest correlation between %TWL and ICIQ-FLUTS score and the weakest correlation between %TWL and CCIS score (p<0.05). CONCLUSIONS We recommend bariatric surgery for the treatment of PFD. However, given the weak correlation between %TWL and PFD after SG, further research should explore factors other than %TWL that are effective in recovery, particularly in relation to FI.

Int J Obes (Lond) 2023:10.1038/s41366-023-01298-1. [PMID: 37005473 DOI: 10.1038/s41366-023-01298-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 03/08/2023] [Accepted: 03/14/2023] [Indexed: 04/04/2023]
Abstract
BACKGROUND Randomized controlled trials (RCTs) are regarded as high-level evidence, but the strength of their P values can be difficult to ascertain. The Fragility Index (FI) is a novel metric that evaluates the frailty of trial findings. It is defined as the minimum number of patients required to change from a non-event to event for the findings to lose statistical significance. This study aims to characterize the robustness of bariatric surgery RCTs by examining their FIs. METHODS A search was conducted in MEDLINE, EMBASE, and CENTRAL from January 2000 to February 2022 for RCTs comparing two bariatric surgeries with statistically significant dichotomous outcomes. Bivariate correlation was conducted to identify associations between FI and trial characteristics. RESULTS A total of 35 RCTs were included with a median sample size of 80 patients (Interquartile range [IQR] 58-109). The median FI was 2 (IQR 0-5), indicating that altering the status of two patients in one treatment arm would overturn the statistical significance of results. Subgroup analyses of RCTs evaluating diabetes-related outcomes produced a FI of 4 (IQR 2-6.5), while RCTs comparing Roux-en-Y gastric bypass and sleeve gastrectomy had an FI of 2 (IQR 0.5-5). Increasing FI was found to be correlated with decreasing P value, increasing sample size, increasing number of events, and increasing journal impact factor. CONCLUSION Bariatric surgery RCTs are fragile, with only a few patients required to change from non-events to events to reverse the statistical significance of most trials. Future research should examine the use of FI in trial design.

Abstract
INTRODUCTION Gastrointestinal symptoms such as diarrhea, bloating, abdominal pain, and nausea are common after bariatric surgery (BS) and can lead to significant morbidity. While many diagnoses can explain these symptoms, post-bariatric exocrine pancreatic insufficiency (EPI) is becoming increasingly recognized as contributor to gastrointestinal symptoms. The frequency and outcomes of EPI after BS are not well understood. We investigated the prevalence and outcomes of EPI over 18 years at a tertiary bariatric referral center. METHODS A retrospective review of patients who underwent primary or revisional BS from 2002 to 2020 was performed. Patients were included if they were suspected of having EPI or underwent fecal elastase testing (FE-1). EPI diagnosis was defined as positive FE-1 testing or improvement with empiric pancreatic enzyme replacement therapy (PERT). RESULTS EPI was suspected in 261 patients, and 190 were tested via FE-1 (89.5%) or empirically treated (10.5%). EPI was diagnosed in 79 (41.6%) patients and was associated with older age and lower BMI. Therapeutic PERT was given to 65 patients diagnosed with EPI, and 56 (86.2%) patients reported improved symptoms. Patients who underwent RYGB and BPD-DS were more likely to have EPI than those after SG (47.9% and 70.0% vs 17.4%, p < 0.01). EPI diagnosis was associated with a history chronic pancreatitis. While diarrhea and abdominal pain were the most common symptoms prompting FE-1 testing, no symptoms were significantly associated with EPI. EPI was also associated with abnormal fecal fat results and treatment with bile acid sequestrants, but not small intestinal bacterial overgrowth. CONCLUSION This study highlights that exocrine pancreatic insufficiency can account to for previously unexplained GI complaints after bariatric surgery. Therefore, bariatric surgery programs should consider this diagnosis in symptomatic patients, especially following RYGB and BPD-DS. Further work to define patient factors that should prompt evaluation, optimal treatment, and prevention is necessary.

Abstract
BACKGROUND The stomach, intestinal, and pylorus-sparing (SIPS) procedure is a single-anastomosis duodeno-intestinal bypass used in obesity management. OBJECTIVE Weight and metabolic outcomes in patients with severe obesity who underwent the SIPS procedure were evaluated in a community hospital-based study. SETTING Community hospital. METHODS This single-site prospective study of patients who underwent the SIPS procedure evaluated outcomes at 12 and 24 months. Mean changes in total weight loss and body mass index (BMI) and resolution of gastroesophageal reflux disease (GERD), obstructive sleep apnea (OSA), hypertension, type 2 diabetes (T2D), and hyperlipidemia were evaluated. RESULTS At baseline, 185 patients were enrolled; mean weight and BMI were 144.0 kg and 52.2 kg/m2, respectively. Data for 88 (47.6%) and 29 (15.7%) patients who completed follow-up at 12 and 24 months, respectively, were available. At 12 months, mean total weight loss was 35.6% (weight reduction of 51.3 kg) and BMI reduction of 17.8 points were achieved and were maintained for the 29 patients who completed 24-month follow-up. No leaks or infections occurred. Complications occurred in 8 patients (.4%) and were not serious. Resolution of GERD, OSA, hypertension, T2D, and hyperlipidemia achieved in 87.1%, 59.2%, 32.7%, 93.1%, and 87.6% of patients, respectively, at 12 months was maintained at 24 months. Nutritional deficiency was absent. CONCLUSIONS Patients who underwent the SIPS procedure had meaningful reductions in weight and BMI, and many had resolution of metabolic co-morbidities; procedural complication rates were low. Our results support that the SIPS procedure is a safe and effective primary treatment for clinically severe obesity in a community-based hospital setting.

Surg Endosc 2022; 36:6896-6902. [PMID: 35132450 PMCID: PMC8821827 DOI: 10.1007/s00464-022-09028-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 01/03/2022] [Indexed: 11/29/2022]
Abstract
INTRODUCTION This study aims to assess the effect of bariatric surgery on patient-reported outcomes of bowel and bladder function. We hypothesized that bariatric surgery does not worsen bowel and bladder function. METHODS AND PROCEDURES A retrospective review was conducted of a prospectively maintained surgical quality database. We included patients who underwent primary bariatric surgery at a single institution between 2012 and 2020, excluding revisional procedures. Patient-reported outcomes were assessed using Surgical Outcomes Measurement System (SOMS) bowel and bladder function questionnaires at time of pre-operative consult and routine post-operative follow-up visits through 2 years. Data were analyzed using a statistical mixed effects model. RESULTS 573 patients (80.6% female) were identified with completed SOMS questionnaire data on bowel and bladder function. Of these, 370 (64.6%) underwent gastric bypass, 190 (33.2%) underwent sleeve gastrectomy, and 13 (2.3%) underwent either gastric banding or duodenal switch. Compared to pre-operative baseline scores, patients reported a transient worsening of bowel function at 2-weeks post-op (p = 0.009). However, by 3-months post-op, bowel function improved and was significantly better than baseline (p = 0.006); this improvement was sustained at every point through 2-year follow-up (p = 0.026). Bladder function scores improved immediately at 2-weeks post-op (p = 0.026) and showed sustained improvement through 1-year follow-up. On subgroup analysis, sleeve patients showed greater improvement in bowel function than bypass patients at 1-year (p = 0.031). Multivariable analysis showed significant improvement in bowel function associated with greater total body weight loss (TBWL) (p = 0.002). CONCLUSIONS Bariatric surgery does not worsen patient-reported bowel or bladder function. In fact, there is overall improvement from pre-operative scores for both bowel and bladder function by 3-months post-op which is sustained through 2-year and 1-year follow-up, respectively. Most encouragingly, a greater TBWL is significantly associated with improved bowel function after bariatric surgery.

Abstract
Background The optimal surgical weight loss procedure for patients with a BMI of 50 kg/m2 or more is uncertain. This study compared distal Roux-en-Y gastric bypass (RYGB) with standard RYGB. Methods In this double-blind RCT, patients aged 18–60 years with a BMI of 50–60 kg/m2 were allocated randomly to receive standard (150 cm alimentary, 50 cm biliopancreatic limb) or distal (150 cm common channel, 50 cm biliopancreatic limb) RYGB. The primary outcome (change in BMI at 2 years) has been reported previously. Secondary outcomes 5 years after surgery, such as weight loss, health-related quality of life, and nutritional outcomes are reported. Results Between May 2011 and April 2013, 123 patients were randomized, 113 received an intervention, and 92 attended 5-year follow-up. Mean age was 40 (95 per cent c.i. 38 to 41) years and 73 patients (65 per cent) were women; 57 underwent standard RYGB and 56 distal RYGB. BMI was reduced by 15.1 (95 per cent c.i. 13.9 to 16.2) kg/m2 after standard and 15.7 (14.5 to 16.9) kg/m2 after distal RYGB; the between-group difference was −0.64 (−2.3 to 1.0) kg/m2 (P = 0.447). Total cholesterol, low-density lipoprotein cholesterol, and haemoglobin A1c levels declined more after distal than after standard RYGB. High-density lipoprotein cholesterol levels increased more after standard RYGB. Vitamin A and vitamin D levels were lower after distal RYGB. Changes in bone mineral density, resting metabolic rate, and total energy intake were comparable. Conclusion Distal RYGB did not enable greater weight loss than standard RYGB. Differences in other outcomes favouring distal RYGB may not justify routine use of this procedure in patients with a BMI of 50–60 kg/m2. Registration number: NCT00821197 (http://www.clinicaltrials.gov).

Abstract
Severe obesity is associated with major health issues and bariatric surgery is still the only treatment to offer significant and durable weight loss. Assessment of dietary intakes is an important component of the bariatric surgery process. Objective: To document the dietary assessment tools that have been used with patients targeted for bariatric surgery and patients who had bariatric surgery and explore the extent to which these tools have been validated. Methods: A literature search was conducted to identify studies that used a dietary assessment tool with patients targeted for bariatric surgery or who had bariatric surgery. Results: 108 studies were included. Among all studies included, 27 used a dietary assessment tool that had been validated either as part of the study per se (n = 11) or in a previous study (n = 16). Every tool validated per se in the cited studies was validated among a bariatric population, while none of the tools validated in previous studies were validated in this population. Conclusion: Few studies in bariatric populations used a dietary assessment tool that had been validated in this population. Additional studies are needed to develop valid and robust dietary assessment tools to improve the quality of nutritional studies among bariatric patients.

Abstract
Gastric bypass surgery is an effective long-term treatment for individuals with severe obesity. Changes in appetite, dietary intake, and food preferences have all been postulated to contribute to postoperative body weight regulation, however, findings are inconsistent. The aim of this systematic review was to evaluate the current literature on changes in dietary intake and appetite following gastric bypass surgery, in the context of the methodology used and the analysis, interpretation, and presentation of results. Four databases were systematically searched with terms related to "gastric bypass surgery," "appetite," and "dietary intake," and 49 papers (n = 2384 patients after gastric bypass) were eligible for inclusion. The evidence indicated that only a reduction in overall energy intake and an increase in postprandial satiety are maintained beyond 6-month post-surgery, whereas relative macronutrient intake and premeal hunger remain unchanged. However, available data were limited by inconsistencies in the methods, analysis, presentation, and interpretation of results. In particular, there was a reliance on data collected by subjective methods with minimal acknowledgment of the limitations, such as misreporting of food intake. There is a need for further work employing objective measurement of appetite and dietary intake following gastric bypass surgery to determine how these mechanisms may contribute to weight regulation in the longer term.

Abstract
BACKGROUND Distal Roux-en-Y gastrojejunal bypass (DRYGJB) gives better weight reduction than standard Roux-en-Y gastric bypass (RYGB) but at the risk of increased malnutrition side-effects. This study compared the effects of RYGB and DRYGJB on gastrointestinal symptoms, eating patterns and health-related quality of life (QoL). METHODS This was a single-blind RCT from a university-affiliated obesity centre. Patients with a BMI of 50 kg/m2 or above were invited to participate. Treatment arms were standard gastric bypass with an alimentary limb of 150 cm and a biliopancreatic limb of 60 cm, with a variable common channel length, or DRYGJB with biliopancreatic limb of 200 cm, common channel limb of 150 cm and variable alimentary limb length. Baseline and follow-up data to 5 years on quality of life, obesity-related problems and gastrointestinal symptoms were collected using prospectively created and validated questionnaires. RESULTS Some 140 patients were included. Those with a DRYGJB had better weight loss at 5 years (mean(s.d.) 68·3(21·8) kg versus 55·7(19·8) kg for standard RYGB; P = 0·011). Eating patterns improved, with no difference between the groups. Gastrointestinal symptoms (diarrhoea, indigestion) worsened significantly in both groups, but only patients with DRYGJB had significantly worse diarrhoea at the end of the study than at baseline (P = 0·006). Both groups had improved perceived generic QoL over baseline, and obesity-related problems were markedly reduced. CONCLUSION Standard RYGB and both improved generic and disease-specific QoL and eating behavioural pattern. Diarrhoea was increased more following DRYGJB than after RYGB. Registration number: NCT01514799 (https://clinicaltrials.gov).

Abstract
BACKGROUND The effect of bariatric surgery on 'emotional eating' (EE) in people with obesity is unclear. This systematic review and meta-analysis aimed to examine changes in self-reported emotional eating behaviour after bariatric surgery. METHODS Fifteen electronic databases were searched from inception to August 2019. Included studies encompassed patients undergoing primary bariatric surgery, quantitatively assessed EE, and reported EE scores before and after surgery in the same participants. Studies were excluded if they were not in English or available in full text. The systematic review and meta-analysis were conducted according to the PRISMA guidelines. Random-effects models were used for quantitative analysis. Study quality was assessed using the National Heart, Lung, and Blood Institute quality assessment tool for before-after (pre-post) studies with no control group. RESULTS Some 23 studies containing 6749 participants were included in the qualitative synthesis, with follow-up of from 2 weeks to 48 months. EE scores decreased to 12 months after surgery. Results were mixed beyond 12 months. Quantitative synthesis of 17 studies (2811 participants) found that EE scores decreased by a standardized mean difference of 1·09 (95 per cent c.i. 0·76 to 1·42) 4-18 months after surgery, indicating a large effect size. CONCLUSION Bariatric surgery may mitigate the tendency to eat in response to emotions in the short to medium term.

Abstract
Weight loss is the primary outcome following bariatric surgery; however, its documentation within current literature is heterogeneous and poorly defined, limiting meaningful comparison between studies. Randomized controlled trials from 2012 to 2016 were identified using the Medline database through "Gastric bypass OR sleeve gastrectomy AND weight" search terms. A total of 73 studies with 5948 patients were included. Reporting of preoperative weight was done primarily using mean body mass index (BMI) (87.7%) and mean weight (65.8%). Postoperative weight reporting was more variable, with the most frequently reported measure being mean postoperative BMI (71.2%). Overall, nearly one third of all bariatric literature contained discrepancies that precluded meaningful meta-analysis. Reporting of weight loss following bariatric surgery is becoming increasingly diverse for both pre- and post-operative outcomes. Ongoing heterogeneity will continue to act as a barrier to meaningful comparison of bariatric outcomes until standardized reporting practices become adopted.

Abstract
Bariatric surgery has emerged as an increasingly popular weight loss intervention, with larger and more endurable weight loss compared to pharmacological and behavioural interventions. The degree of weight loss patients experience varies, between individuals, surgeries and over time. An explanation as to why differing weight loss trajectories exist post-surgery could be due to the complex interplay of individual differences in relation to eating behaviours and appetite. Thus the aim of this narrative review is to explore literature between 2008 and 2018, to assess the impact of impact of bariatric surgery on food selection and nutrient status, on eating behaviour traits and on disturbed and disordered eating behaviour, to determine their impact of weight loss success and weight loss trajectories. Immediately post-surgery, up until 1-2 years post-surgery, there is a reliance upon the surgery's alteration of the gastrointestinal tract to control food intake and subsequently lose weight. Energy intake is reduced, dietary adherence is higher, supplement intake is higher, appetite ratings are lower, there is a reduction in psychopathology, and an increase in wellbeing. After this point, patients become more susceptible to weight regain, as this is the point where passive observation of the weight reducing action of surgery, moves into more cognitive effort, on the part of the individual, to control energy intake. There are various factors which influence an individual's ability to successfully regulate their energy intake post-surgery, such as their level of Disinhibition, Restraint, Hunger, Emotional Eating, Uncontrolled Eating, psychopathology and wellbeing. The need for continued psychological and nutritional support post-surgery is necessary to reduce weight regain susceptibility.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is prevalent in patients with morbid obesity. After Roux-en-Y gastric bypass (RYGB) chronic abdominal pain is common, however the etiology is largely unknown. We aimed to study the change in the prevalence of IBS-like symptoms 2 years after RYGB and possible preoperative predictors of such symptoms. Secondly, to evaluate changes in symptoms of constipation and diarrhea, and Health related quality of life (HRQoL). METHODS Patients with morbid obesity were included at two obesity centers in South-Eastern Norway. IBS was diagnosed according to the Rome III criteria. Predictors were evaluated in a multivariable logistic regression analysis. RESULTS Of 307 participants operated with RYGB, 233 (76%) completed the study questionnaires. Preoperatively 27/233 participants (12%) had IBS, 2 years after RYGB 61/233 (26%) had IBS-like symptoms (p < 0.001). Eleven participants with IBS preoperatively (41%) did not report such symptoms after RYGB. New onset IBS-like symptoms was identified in 45/206 (22%) after RYGB. Fibromyalgia, low LDL levels, high vitamin B1 levels and IBS before RYGB were independent preoperative predictors of IBS-like symptoms at the follow-up visit. Symptom scores for constipation preoperatively and 2 year after RYGB were 1.5 (0.9) and 1.8 (1.2), and for diarrhea 1.4 (0.9) and 1.8 (1.1), respectively (p < 0.001). We observed a significant improvement in the physical component score for all participants. However, participants with new onset IBS-like symptoms had a significant worsening of the mental component score. CONCLUSIONS The prevalence of IBS-like symptoms doubled 2 years after RYGB, and these symptoms were associated with reduced HRQoL. Preoperative IBS and fibromyalgia were strong predictors of postoperative IBS-like symptoms.

Abstract
PURPOSE OF REVIEW Literature from the past five years exploring roles of Three-Factor Eating Questionnaire (TFEQ) Restraint and Disinhibition in relation to adult obesity and eating disturbance (ED) was reviewed. RECENT FINDINGS Restraint has a mixed impact on weight regulation, diet quality, and vulnerability to ED, where it is related detrimentally to weight regulation, diet, and psychopathology, yet can serve as a protective factor. The impact of Disinhibition is potently related to increased obesity, poorer diet, hedonically driven food choices, and a higher susceptibility to ED. Restraint and Disinhibition have distinct influences on obesity and ED and should be targeted differently in interventions. Further work is required to elucidate the mechanisms underlying TFEQ eating behavior traits.

Abstract
Introduction The aim of the present study was to look at longitudinal changes in children’s self-concept, body-esteem, and eating attitudes before and 4 years after maternal RYGB surgery. Methods Sixty-nine women and 81 appurtenant children were recruited from RYGB waiting lists at 5 hospitals in Sweden. Families were visited at home pre-surgery, 9 months, and 4 years post-maternal RYGB to measure BMI. Furthermore, all participating family members completed questionnaires. Mothers’ questionnaires measured eating behavior, depression, anxiety, and sleep quality, and children’s questionnaires measured body-esteem, self-concept, and eating attitudes. Results Thirty-five/sixty-nine mothers and 43/81 children participated in all 3 measurements. Mothers reduced their BMI from pre-surgery (39.2) to 9 months (27.0) and 4 years post-surgery (27.4). Children’s prevalence of overweight/obesity was lower 9 months post-surgery (48.8%) but at the same levels again 4 years post-surgery (58.1%), compared to pre-surgery (58.1%). The same rebound pattern was seen among children’s eating attitudes, mothers’ symptoms of depression and anxiety, and sleep quality. We found no correlations between mothers’ BMI or eating behavior and children’s BMI or eating behavior. Conclusion Children’s prevalence of overweight/obesity and eating attitudes improves soon after their mothers’ RYGB, but then return to pre-surgery levels at 4 years post-surgery, as do mothers’ sleep quality and symptoms of depression and anxiety, even though their weight loss was maintained.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is an effective treatment for morbid obesity, but many patients have increased gastrointestinal symptoms. OBJECTIVES To evaluate gastrointestinal symptoms and food intolerance before and after RYGB over time in a large cohort of morbidly obese patients. SETTING A high-volume bariatric center of excellence. METHODS A prospective cohort study was performed in patients who underwent RYGB between September 2014 and July 2015, with 2-year follow-up. Consecutive patients screened for bariatric surgery answered the Gastrointestinal Symptom Rating Scale (GSRS) and a food intolerance questionnaire before RYGB and 2 years after surgery. The prevalence of gastrointestinal symptoms before and after surgery and the association between patient characteristics and postoperative gastrointestinal symptoms were assessed. RESULTS Follow-up was 86.2% (n = 168) for patients undergoing primary RYGB and 93.3% (n = 28) for revisional RYGB. The total mean GSRS score increased from 1.69 to 2.31 after surgery (P < .001), as did 13 of 16 of the individual scores. Preoperative GSRS score is associated with postoperative symptom severity (B = .343, P < .001). Food intolerance was present in 16.1% of patients before primary RYGB, increasing to 69.6% after surgery (P < .001). Patients who underwent revisional RYGB had a symptom severity and prevalence of food intolerance comparable with that among patients with primary RYGB, even though they had more symptoms before revisional surgery. CONCLUSIONS Two years after surgery, patients who underwent primary RYGB have increased gastrointestinal symptoms and food intolerance compared with the preoperative state. It is important that clinicians are aware of this and inform patients before surgery.

Abstract
BACKGROUND The preferred surgical procedure for treating morbid obesity is debated. Patient-reported outcome measures (PROMs) are relevant for evaluation of the optimal bariatric procedure. METHODS A total of 113 patients with BMI from 50 to 60 were randomly assigned to standard (n = 57) or distal (n = 56) Roux-en-Y gastric bypass (RYGB). Validated PROMS questionnaires were completed at baseline and 2 years after surgery. Data were analyzed using mixed models for repeated measures and the results are expressed as estimated means and mean changes. RESULTS Obesity-related quality of life improved significantly after both procedures, without significant between-group differences (- 0.4 (95% CI = - 8.4, 7.2) points, p = 0.88, ES = 0.06). Both groups had significant reductions in the number of weight-related symptoms and symptom distress score, with a mean group difference (95% CI) of 1.4 (- 0.3, 3.3) symptoms and 5.0 (2.9. 12.8) symptom distress score points. There were no between-group differences for uncontrolled eating (22.0 (17.2-26.7) vs. 28.9 (23.3-34.5) points), cognitive restraint (57.4 (52.0-62.7) vs. 62.1 (57.9-66.2) points), and emotional eating (26.8 (20.5-33.1) vs. 32.6 (25.5-39.7) points). The prevalence of anxiety was 33% after standard and 25% after distal RYGB (p = 0.53), and for depression 12 and 9%, respectively (p = 0.76). CONCLUSIONS There were no statistically significant differences between standard and distal RYGB 2 years post surgery regarding weight loss, obesity-related quality of life, weight-related symptoms, anxiety, depression, or eating behavior.

Abstract
BACKGROUND Bariatric procedures are increasingly being used, but data on bowel habits are scarce. OBJECTIVES To assess changes in gastrointestinal function and patient-scored symptoms after Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion with duodenal switch (BPD/DS). SETTING University hospital in Sweden. METHODS We recruited 268 adult patients (mean age of 42.5 yr, body mass index 44.8, 67.9% female) listed for RYGB and BPD/DS. Patients answered validated questionnaires prospectively concerning bowel function, the Fecal Incontinence Quality of Life Scale, and the 36-Item Short Form Health Survey before and after their operation. RESULTS Postoperatively, 208 patients (78.2% of 266 eligible patients) answered the questionnaires. RYGB patients had fewer bowel motions per week (8 versus 10) and more abdominal pain postoperatively (P<.001). Postoperatively, the 35 BPD/DS patients (69% versus 23%) needed to empty their bowel twice or more than twice daily, reported more flatus and urgency, and increased need for keeping a diet (P<.001). Concerning Fecal Incontinence Quality of Life Scale, coping and behavior was slightly reduced while depression and self-perception scores were improved after RYGB. Lifestyle, coping and behavior, and embarrassment were reduced after BPD/DS (P<.05). In the 36-Item Short Form Health Survey, physical scores were markedly improved, while mental scores were largely unaffected. CONCLUSION RYGB resulted in a reduced number of bowel movements but increased problems with abdominal pain. In contrast, BPD/DS-patients reported higher frequency of bowel movements, more troubles with flatus and urgency, and increased need for keeping a diet. These symptoms affected quality of life negatively, however, general quality of life was markedly improved after both procedures. These results will be of great value for preoperative counseling.

Abstract
Diarrhea after bariatric procedures, mainly those with malabsorptive elements including Roux-Y Gastric Bypass and Biliopancreatic Diversion, is common and an essential determinant of quality of life and micro- and macronutrient deficiencies. Bariatric surgery is the only sustainably successful method to address morbid obesity and its comorbidities, particularly gaining more and more importance in the specific treatment of diabetic patients. Approximately half a million procedures are annually performed around the world, with numbers expected to rise drastically in the near future. A multitude of factors exert their influence on bowel habits; preoperative comorbidities and procedure-related aspects are intertwined with postoperative nutritional habits. Diagnosis may be challenging owing to the characteristics of post-bariatric surgery anatomy with hindered accessibility of excluded segments of the small bowel and restriction at the gastric level. Conventional testing measures, if available, generally yield low accuracy and are usually not validated in this specific population. Limited trials of empiric treatment are a practical alternative and oftentimes an indispensable part of the diagnostic process. This review provides an overview of causes for chronic post-bariatric surgery diarrhea and details the particularities of its diagnosis and treatment in this specific patient population. Topics of current interest such as the impact of gut microbiota and the influence of bile acids on morbid obesity and especially their role in diarrhea are highlighted in order to provide a better understanding of the specific problems and chances of future treatment in post-bariatric surgery patients.

Abstract
OBJECTIVE Most weight loss research focuses on weight as the primary outcome, often to the exclusion of other physiological or psychological measures. This study aims to provide a holistic evaluation of the effects from weight loss interventions for individuals with obesity by examining the physiological, psychological and eating disorders outcomes from these interventions. METHODS Databases Medline, PsycInfo and Cochrane Library (2011-2016) were searched for randomised controlled trials and systematic reviews of obesity treatments (dietary, exercise, behavioural, psychological, pharmacological or surgical). Data extracted included study features, risk of bias, study outcomes, and an assessment of treatment impacts on physical, psychological or eating disorder outcomes. RESULTS From 3628 novel records, 134 studies met all inclusion criteria and were evaluated in this review. Lifestyle interventions had the strongest evidence base as a first-line approach, with escalation to pharmacotherapy and bariatric surgery in more severe or complicated cases. Quality of life was the most common psychological outcome measure, and improved in all cases where it was assessed, across all intervention types. Behavioural, psychological and lifestyle interventions for weight loss led to improvements in cognitive restraint, control over eating and binge eating, while bariatric surgery led to improvements in eating behaviour and body image that were not sustained over the long-term. DISCUSSION Numerous treatment strategies have been trialled to assist people to lose weight and many of these are effective over the short-term. Quality of life, and to a lesser degree depression, anxiety and psychosocial function, often improve alongside weight loss. Weight loss is also associated with improvements in eating disorder psychopathology and related measures, although overall, eating disorder outcomes are rarely assessed. Further research and between-sector collaboration is required to address the significant overlap in risk factors, diagnoses and treatment outcomes between obesity and eating disorders.

Abstract
BACKGROUND Despite accumulating evidence of the important health benefits of bariatric surgery in morbidly obese patients in general, bariatric surgery outcomes are less clear in higher-risk, high-priority populations of patients with BMI ≥ 50 kg/m2. To help the Department of Veterans Affairs (VA) Health Services Research & Development Service (HSR&D) develop a research agenda, we conducted a rapid evidence review to better understand bariatric surgery outcomes in adults with BMI ≥ 50 kg/m2. METHODS We searched MEDLINE®, the Cochrane Database of Systematic Reviews, the Cochrane Central Registry of Controlled Trials, and ClinicalTrials.gov through June 2016. We included trials and observational studies. We used pre-specified criteria to select studies, abstract data, and rate internal validity and strength of the evidence (PROSPERO registration number CRD42015025348). All decisions were completed by one reviewer and checked by another. RESULTS Among 1892 citations, we included 23 studies in this rapid review. Compared with usual care, one large retrospective VA study provided limited evidence that bariatric surgery can lead to increased mortality in the first year, but decreased mortality long-term among super obese veterans. Studies that compared different bariatric surgical approaches suggested some differences in weight loss and complications. Laparoscopic gastric bypass generally resulted in greater short-term proportion of excess weight loss than did other procedures. Duodenal switch led to greater long-term weight loss than did gastric bypass, but with more complications. CONCLUSIONS The published literature that separates the super obese is insufficient for determining the precise balance of benefits and harms of bariatric surgery in this high-risk subgroup. Future studies should evaluate a more complete set of key outcomes with longer follow-up in larger samples of more broadly representative adults.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) is an effective treatment for morbid obesity, but might aggravate gastrointestinal complaints and food intolerance. The long-term prevalence of these symptoms has not been well studied. METHODS In a cross-sectional study, all patients who underwent primary LRYGB from May to October 2012 were approached 2 years after surgery to complete a general health questionnaire, the Gastrointestinal Symptom Rating Scale (GSRS), and a food intolerance questionnaire. The results were compared with those for a control group of morbidly obese patients. RESULTS A total of 249 patients were included for analysis, representing a response rate of 93·9 per cent. Mean(s.d.) total weight loss was 30·8(8·7) per cent. The total mean GSRS score was higher in patients who had LRYGB (median 2·19 versus 1·75 in unoperated patients; P < 0·001); the difference in symptoms of indigestion was most notable (P < 0·001). Food intolerance for specific products was reported by 70·7 (95 per cent c.i. 64·8 to 76·0) per cent of the postoperative patients, for a median of 4 foods. There was a positive correlation between food intolerance and score on the GSRS. There was no correlation between either food intolerance or the total mean GSRS score and weight loss, but there was a correlation between weight loss and abdominal pain. CONCLUSION At 2 years after surgery, patients undergoing LRYGB for morbid obesity have more gastrointestinal complaints than obese controls. Food intolerance is a common side-effect of LRYGB independent of degree of weight loss or the presence of other abdominal symptoms.

Abstract
Early dumping syndrome after gastric bypass surgery due to rapid delivery of hyperosmolar nutrients into the bowel causing intense symptoms is often described as a complication. Twelve patients, mean age 47 years, were interviewed approximately 9 years post-operation. The interviews were audiotaped and transcribed verbatim, followed by an inductive content analysis to reveal patients' experience of the dumping syndrome. The core category 'Dumping syndrome is a positive consequence of Roux-en-Y gastric bypass surgery and a tool to control food intake' was identified based on the following four sub-categories: (i) 'The multidimensional emergence and effects of dumping syndrome', (ii) 'Dumping syndrome as something positive although unpleasant', (iii) 'Developing coping mechanisms and ingenious strategies' and (iv) 'My own fault if I expose myself to dumping syndrome'. From the patients' perspective, dumping syndrome gives control over food intake; although the symptoms were unpleasant, patients considered dumping syndrome as a positive protection against over-consumption. Hence, healthcare professionals should not present dumping syndrome as a complication but rather as an aid to control eating behaviour and excessive food intake.

Abstract
BACKGROUND Food cravings and consumption of craved foods after Roux-en-Y gastric bypass (RYGB) are poorly understood. Food cravings after bariatric surgery may explain why some patients fail to change eating behaviors after RYGB, and understanding these cravings may provide better information for nutritional counseling to either enhance weight loss or prevent weight regain. OBJECTIVES To study cravings in RYGB patients and compare them with cholecystectomy (CC) control patients. SETTING This study took place in a university hospital. METHODS RYGB patients (n = 50) and CC control patients (n = 38) completed a validated food craving inventory before surgery and at 2 and 6 weeks postoperatively. In addition, RYGB patients completed the food craving inventory at 12, 24, 36, and 52 weeks postoperatively. A linear mixed-effect model with a first-order autoregressive structure for correlations was used to evaluate changes in food consumption and food cravings between visits. Correlations between food cravings and body mass index (BMI) or weight changes before and after RYGB were assessed with Spearman correlation coefficients. P<.05 was considered statistically significant. RESULTS After RYGB, food consumption decreased significantly compared with CC control patients and was lowest at 2 weeks. Consumption progressively increased over time in the first year but remained significantly less than that from presurgery. In addition, a higher preoperative BMI was found to correlate moderately with higher preoperative cravings of the total of all 4 food groups studied (r = .3, P = .04); high-fat foods (r = .3, P = .04); and sweets (r = .3, P = .03). However, with the exception of preoperative cravings for high-fat foods, these scores were not predictive of changes in BMI after surgery. Overall, RYGB did not significantly affect food cravings after surgery compared with CC control patients. CONCLUSION These findings indicate that RYGB may limit food consumption but does not affect the drive to consume certain types of food. Because food cravings are high in patients with obesity before surgery and remain high after surgery, these findings suggest a possible reason for noncompliance with dietary recommendations after RYGB.

Abstract
BACKGROUND The Roux-en-Y gastric bypass (RYGB) still remains the gold standard in bariatric surgery. However, no consensus exists on the optimal limb lengths to induce maximum weight reduction. The aim of the present study was to assess the effect of a longer alimentary limb (AL) length on weight reduction after RYGB. METHODS A retrospective analysis of a prospectively collected database of patients who underwent a primary laparoscopic RYGB between January 2001 and March 2011 was performed. Patients received a short AL (SAL; 100 cm) or a long AL (LAL; 150 cm). Primary outcome was weight loss, and secondary outcomes were short- and long-term complication rates. RESULTS A total of 768 patients received a RYGB during the study period. Of these, 730 consecutive patients were included for long-term analysis and had a mean follow-up (FU) of 37 ± 26 [range 0-120] months; 360 (47 %) patients received a SAL RYGB. Overall %TBWL was 33 ± 9 % after 2 years (FU 74 %) and 28 ± 12 % after 5 years (FU 20 %). No significant differences in %TBWL were found between SAL RYGB and LAL RYGB during the study period. The 30-day mortality rate was 0.13, 9 % overall short-term complication rate and 19 % cumulative long-term complication rate. No differences in complications were found between SAL and LAL RYGB patients. CONCLUSION Lengthening of the alimentary limb from 100 to 150 cm did not affect post-RYGB weight loss. Overall complication rates were low and comparable in this series of RYGB patients.

Abstract
Background To examine whether a preoperative cognitive behavioural therapy (CBT) intervention exceeds usual care in the improvements of dysfunctional eating behaviours, mood, affective symptoms and body weight 1 year after bariatric surgery. Methods This is a 1-year follow-up of a single centre parallel-group randomised controlled trial (http://clinicaltrials.gov/ct2/show/NCT01403558). A total of 80 (55 females) patients mean (SD) age 44 (10) years were included. The intervention group received 10 weeks of CBT prior to bariatric surgery, and the control group received nutritional support and education. Both groups were assessed at baseline (T0), post CBT intervention/preoperatively (T1), and 1 year postoperatively (T2). Using a mixed modelling statistical approach, we examined if the CBT group improved more across time than the control group. Results Our hypothesis was not supported as both groups had comparable improvements in all outcomes except for anxiety symptoms. Body weight declined by 30.2 % (37.3 kg) in the CBT group and by 31.2 % (40.0 kg) in the control group from baseline to follow-up, p = 0.82. There were statistically significant reductions in anxiety and depression symptoms in the CBT group between T0 and T1 and between T1 and T2 for depression only. However, in the control group, the anxiety score did not change significantly. The CBT group showed an earlier onset of improvements in all eating behaviours and affective symptoms than the control group. Conclusion The 10-week CBT intervention showed beneficial effects preoperatively, but the non-significant group differences postoperatively indicate a genuine effect of surgery.

Abstract
BACKGROUND In several developed countries, as obesity prevalence doubles it has quadrupled for morbid obesity (BMI ≥ 40 kgm-2). As more individuals with morbid obesity present for weight loss treatment there is a greater need to understand their dietary habits. No reviews were found in the literature, therefore this systematic review aims to identify and describe the existing evidence on the usual dietary intake of individuals with morbid obesity including those from a general population and those seeking treatment such as weight loss surgery. METHODS A literature search of ten databases from 1980 to June 2014 was conducted to identify original research of adults with morbid obesity (aged 18-60 years) that reported a usual dietary intake. RESULTS Ten studies met all inclusion criteria and reported energy intake, most reported macronutrient composition, two assessed micronutrient intake, and one reported food-based outcomes. Other dietary outcomes were related to surgical intervention. The most plausible energy intake data suggest high intakes, >4000 Kcal/day for those weight stable at the highest levels of morbid obesity (up to BMI 97 kgm-2). Fat intakes are also high, around 40% of energy intake and up to 57% for some individuals. Suboptimal intakes of iron and calcium are reported. CONCLUSION This review draws attention to a limited evidence base, offers preliminary insight suggesting individuals with morbid obesity are prone to consuming poor quality diets similar to those reported for obese populations, and highlights challenges for future research.

Abstract
Background. The aims of this study were to translate the Obesity-Related Problem scale (OP scale) into the Norwegian language and test its reliability, validity and responsiveness in a Norwegian sample. Method. The questionnaire (OP scale) was translated from the original language (Swedish) into Norwegian. Patients completed the questionnaire prior to and one year after sleeve gastrectomy. Internal consistency was evaluated using Cronbach's α. Construct validity was tested by correlating the OP-scale with the SF-36 and the Cantril Ladder using the Pearson correlation coefficient. An exploratory and confirmatory factor analysis was used to test the unidimensionality of the OP scale. Responsiveness was tested by assessing changes in the OP scale from baseline to one year post-surgery using the paired sample t-test. Floor and ceiling effect were calculated as percentages. Results. A total of 181 patients (123 women) accepted for bariatric surgery was included in the study. The mean age was 43.1 ± 12.5 years, and mean body mass index (BMI) before surgery was 45 ± 6.9. The mean value of the OP scale at baseline was 63.30 ± 24.43 (severe impairment) and 21.01 ± 20.98 at one year follow-up (mild impairment). Internal consistency was high at baseline (Cronbach's α 0.91). The floor effect was small at baseline and high at one year. The ceiling effect was small at baseline and at one year. Exploratory and conformatory factor analysis showed one factor with a high percent of explained variance. Correlations between OP scale at baseline, SF-36, Cantril Ladder and BMI were statistically significant and in the predicted direction to support validity of the Norwegian OP scale. After one year correlations between the change in OP scale and the change in SF-36 scores, Cantril Ladder and BMI were also statistically significant, except for the change in the Role Physical-scale. The OP scale showed greater responsiveness than either the SF-36 or Cantril Ladder. Conclusion. These results confirm that the Norwegian version of the OP scale is a valid and reliable instrument for measuring psychosocial functioning in patients with clinically severe obesity.

Changes in eating behaviour and food choices in families where the mother undergoes gastric bypass surgery for obesity. Eur J Clin Nutr 2015; 70:35-40.

Abstract
BACKGROUND/OBJECTIVES There is a lack of research exploring the effects of Roux-en-Y gastric bypass (RYGB) surgery on the patient's family's eating behaviour and food choices. The aim of the current study was to investigate changes in partners' and children's eating behaviour and food choices following maternal RYGB. SUBJECTS/METHODS Sixty-nine women and their families were recruited from RYGB waiting lists at five Swedish surgical clinics. Data were collected during home visits 3 months before and 9 months after RYGB. Anthropometrical measures were taken, the adults completed the Three-Factor Eating Questionnaire and the children completed the Children's Eating Attitudes Test (ChEAT). All participants also completed a short food frequency questionnaire. RESULTS Changes in scores were analysed using paired t-tests for unadjusted estimates or linear regression models with robust variance (General Estimating Equations) in order to enable age- and sex-adjusted estimates for the children. There were no meaningful differences in the partners' eating behaviour or food choices. The boys, but not the girls, improved their ChEAT scores, as did the overweight/obese children in comparison with the normal-weight children. The boys, unlike the girls, also decreased their intake of soft drinks, as did the normal-weight children when compared with the overweight/obese children. CONCLUSIONS No clear-cut changes were found in partners' eating behaviour and food choices. Eating attitudes and soft drinks intake were improved among boys but not among girls. Differing modelling behaviour may partially explain these findings, but available data did not allow us to understand the underlying mechanisms.

Abstract
BACKGROUND Bariatric (weight loss) surgery for obesity is considered when other treatments have failed. The effects of the available bariatric procedures compared with medical management and with each other are uncertain. This is an update of a Cochrane review first published in 2003 and most recently updated in 2009. OBJECTIVES To assess the effects of bariatric surgery for overweight and obesity, including the control of comorbidities. SEARCH METHODS Studies were obtained from searches of numerous databases, supplemented with searches of reference lists and consultation with experts in obesity research. Date of last search was November 2013. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing surgical interventions with non-surgical management of obesity or overweight or comparing different surgical procedures. DATA COLLECTION AND ANALYSIS Data were extracted by one review author and checked by a second review author. Two review authors independently assessed risk of bias and evaluated overall study quality utilising the GRADE instrument. MAIN RESULTS Twenty-two trials with 1798 participants were included; sample sizes ranged from 15 to 250. Most studies followed participants for 12, 24 or 36 months; the longest follow-up was 10 years. The risk of bias across all domains of most trials was uncertain; just one was judged to have adequate allocation concealment.All seven RCTs comparing surgery with non-surgical interventions found benefits of surgery on measures of weight change at one to two years follow-up. Improvements for some aspects of health-related quality of life (QoL) (two RCTs) and diabetes (five RCTs) were also found. The overall quality of the evidence was moderate. Five studies reported data on mortality, no deaths occurred. Serious adverse events (SAEs) were reported in four studies and ranged from 0% to 37% in the surgery groups and 0% to 25% in the no surgery groups. Between 2% and 13% of participants required reoperations in the five studies that reported these data.Three RCTs found that laparoscopic Roux-en-Y gastric bypass (L)(RYGB) achieved significantly greater weight loss and body mass index (BMI) reduction up to five years after surgery compared with laparoscopic adjustable gastric banding (LAGB). Mean end-of-study BMI was lower following LRYGB compared with LAGB: mean difference (MD) -5.2 kg/m² (95% confidence interval (CI) -6.4 to -4.0; P < 0.00001; 265 participants; 3 trials; moderate quality evidence). Evidence for QoL and comorbidities was very low quality. The LRGYB procedure resulted in greater duration of hospitalisation in two RCTs (4/3.1 versus 2/1.5 days) and a greater number of late major complications (26.1% versus 11.6%) in one RCT. In one RCT the LAGB required high rates of reoperation for band removal (9 patients, 40.9%).Open RYGB, LRYGB and laparoscopic sleeve gastrectomy (LSG) led to losses of weight and/or BMI but there was no consistent picture as to which procedure was better or worse in the seven included trials. MD was -0.2 kg/m² (95% CI -1.8 to 1.3); 353 participants; 6 trials; low quality evidence) in favour of LRYGB. No statistically significant differences in QoL were found (one RCT). Six RCTs reported mortality; one death occurred following LRYGB. SAEs were reported by one RCT and were higher in the LRYGB group (4.5%) than the LSG group (0.9%). Reoperations ranged from 6.7% to 24% in the LRYGB group and 3.3% to 34% in the LSG group. Effects on comorbidities, complications and additional surgical procedures were neutral, except gastro-oesophageal reflux disease improved following LRYGB (one RCT). One RCT of people with a BMI 25 to 35 and type 2 diabetes found laparoscopic mini-gastric bypass resulted in greater weight loss and improvement of diabetes compared with LSG, and had similar levels of complications.Two RCTs found that biliopancreatic diversion with duodenal switch (BDDS) resulted in greater weight loss than RYGB in morbidly obese patients. End-of-study mean BMI loss was greater following BDDS: MD -7.3 kg/m² (95% CI -9.3 to -5.4); P < 0.00001; 107 participants; 2 trials; moderate quality evidence). QoL was similar on most domains. In one study between 82% to 100% of participants with diabetes had a HbA1c of less than 5% three years after surgery. Reoperations were higher in the BDDS group (16.1% to 27.6%) than the LRYGB group (4.3% to 8.3%). One death occurred in the BDDS group.One RCT comparing laparoscopic duodenojejunal bypass with sleeve gastrectomy versus LRYGB found BMI, excess weight loss, and rates of remission of diabetes and hypertension were similar at 12 months follow-up (very low quality evidence). QoL, SAEs and reoperation rates were not reported. No deaths occurred in either group.One RCT comparing laparoscopic isolated sleeve gastrectomy (LISG) versus LAGB found greater improvement in weight-loss outcomes following LISG at three years follow-up (very low quality evidence). QoL, mortality and SAEs were not reported. Reoperations occurred in 20% of the LAGB group and in 10% of the LISG group.One RCT (unpublished) comparing laparoscopic gastric imbrication with LSG found no statistically significant difference in weight loss between groups (very low quality evidence). QoL and comorbidities were not reported. No deaths occurred. Two participants in the gastric imbrication group required reoperation. AUTHORS' CONCLUSIONS Surgery results in greater improvement in weight loss outcomes and weight associated comorbidities compared with non-surgical interventions, regardless of the type of procedures used. When compared with each other, certain procedures resulted in greater weight loss and improvements in comorbidities than others. Outcomes were similar between RYGB and sleeve gastrectomy, and both of these procedures had better outcomes than adjustable gastric banding. For people with very high BMI, biliopancreatic diversion with duodenal switch resulted in greater weight loss than RYGB. Duodenojejunal bypass with sleeve gastrectomy and laparoscopic RYGB had similar outcomes, however this is based on one small trial. Isolated sleeve gastrectomy led to better weight-loss outcomes than adjustable gastric banding after three years follow-up. This was based on one trial only. Weight-related outcomes were similar between laparoscopic gastric imbrication and laparoscopic sleeve gastrectomy in one trial. Across all studies adverse event rates and reoperation rates were generally poorly reported. Most trials followed participants for only one or two years, therefore the long-term effects of surgery remain unclear.
