Abstract
The obesity epidemic is growing and poses significant risks to pregnancy. Metabolic impairment can be associated with short- and long-term maternal and perinatal morbidity and mortality. The cardiovascular implications are known in those with metabolic disorder outside of pregnancy; however, little is known of the cardiac function in pregnancies complicated by obesity. Maternal cardiac adaptation plays a vital role in normal pregnancy and is known to be involved in the pathophysiology of adverse pregnancy outcomes. Bariatric surgery is the most successful treatment for sustainable weight loss and pre-pregnancy bariatric surgery can drastically change the maternal metabolic profile and pregnancy outcomes. In this review, we discuss the available evidence on maternal cardiac function in pregnancies affected by obesity and its associated consequences of gestational diabetes and hypertension (chronic and hypertensive disorders in pregnancy), as well as pregnancies following bariatric surgery.

Int J Surg Case Rep 2022; 98:107483. [PMID: 36037639 PMCID: PMC9433662 DOI: 10.1016/j.ijscr.2022.107483] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Revised: 07/29/2022] [Accepted: 08/06/2022] [Indexed: 11/28/2022] Open
Abstract
Introduction and importance Although bariatric surgeries are an increasingly popular option to achieve significant weight loss in patients who fail to do so via conservative measures, these procedures are invasive and carry a risk of complications, many of which are serious and potentially fatal. In this context, endoscopic bariatric therapies (EBT) such as primary obesity surgery endolumenal (POSE) have been proposed as a new minimally invasive weight loss procedure to reduce the risk of postoperative complications. However, these procedures are in their early stages, with only a few cases reported in literature. We report our experience in managing a complicated case of POSE gastroplasty. Case presentation We report a case of a 45-year-old woman presenting with severe epigastric pain and vomiting. She was suffering from postoperative complications following a transoral gastroplasty procedure. The patient was managed surgically to correct the offending complication, which consequently resulted in reversal of POSE. Clinical discussion Conventional bariatric surgical procedures are generally performed using an open and/or laparoscopic approach. Although highly effective, this approach is associated with significant complications. EBTs are gaining traction as novel treatment modalities for obesity. A major reason for adopting this approach is the fact that endoluminal therapy represents a minimally invasive treatment option for obesity with a minimal rate of complications. Conclusion Due to the fact that POSE reversal has never been reported or discussed, especially in the context of gastric perforation, it is imperative that future studies are conducted on the matter. Endoscopic bariatric therapies (EBT) like Primary Obesity Surgery Endolumenal (POSE) offer an outpatient and minimally invasive alternative to traditional bariatric surgery. Typical complications of POSE are minor and include nausea, vomiting, and abdominal pain, while the rarer, major complications include GI bleeding, perforation, severe pain, or hepatic abscess. Conservative management remains the mainstay of treatment for most complications associated with POSE. While POSE has been deemed relatively safe, severe complications such as acute abdomen secondary to gastric perforation necessitate revision and reversal of the procedure.

Appetite Changes in Weight Regain and Weight Maintenance After Roux-en-Y Gastric Bypass. Obes Surg 2022; 32:1-12. [PMID: 35441332 DOI: 10.1007/s11695-022-06061-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 04/11/2022] [Accepted: 04/13/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Roux-en-Y gastric bypass (RYGB) surgery produces significant weight loss. However, a number of patients experience weight regain years after surgery. Factors driving weight regain after surgical interventions are currently being explored. Our objective was to investigate appetite-related measures associated with weight regain after RYGB surgery. MATERIALS AND METHODS Using a cross-sectional design, 29 participants (49.6 ± 9.1 years of age; current BMI 32.4 ± 4.7 kg/m2, 43.6 ± 8.9 months post-RYGB) were stratified into tertiles according to weight regain per month after nadir (weight maintenance (WM), n = 9; low weight regain (LWR), n = 10; and high weight regain (HWR), n = 10). The average weight regain was, by design, significantly different between the groups (WM = 2.2 ± 2.5 kg; LWR = 10.0 ± 3.4 kg; HWR = 14.9 ± 6.3 kg regained, p < 0.05). Appetite (visual analog scales), olfactory performance ("sniffin sticks"), eating behaviors (Three Factor Eating Questionnaire), food reward (Leeds Food Preference Questionnaire), and appetite-related hormones (ghrelin, PYY, GLP-1 and leptin) were measured fasting and in response to a standardized test meal. RESULTS Dietary restraint was significantly higher than clinical cutoffs in WM and LWR (p < 0.05). As expected, significant time effects were noted for ghrelin, PYY, and GLP-1, but there were no group differences. CONCLUSION The results suggest that appetite-related outcomes are similar across individuals who have maintained weight loss and experienced regain following RYGB.

Abstract
BACKGROUND While bariatric surgery has demonstrated physical and psychological benefits, a risk of suicide and non-fatal self-harm has also been shown. The aim of this study was to compared the rate of hospitalization for self-harm during a three-year observational follow-up period between adolescents/young adults who underwent bariatric surgery in France in 2013-2014 and two control groups. METHODS All individuals aged 12-25 years old who underwent bariatric surgery in France between January 1st, 2013, and December 31st, 2014, were identified with a validated algorithm from the French national hospital database, and compared to a healthy sample of the general population matched for age and gender. Information relative to hospitalizations, including for self-harm (ICD-10 codes X60-84), were extracted i) between 2008 and the surgery, and ii) for a three-year follow-up period. A second unmatched control group with obesity but no bariatric surgery was also identified. Survival analyses with adjustments for confounding variables were used. RESULTS In 2013-2014, 1984 youths had bariatric surgery in France. During follow-up, 1.5% were hospitalized for self-harm vs. 0.3% for controls (p < 0.0001). After adjustment, subsequent hospitalization for self-harm was associated with bariatric surgery (HR 3.64, 95% CI 1.70-7.81), prior psychiatric disorders (HR 7.76, 95% CI 3.76-16.01), and prior self-harm (HR 4.43, 95% CI 1.75-11.24). When compared to non-operated youths with obesity, bariatric surgery was not associated with self-harm while prior mental disorders and self-harm were. Mortality reached 0.3% after surgery. CONCLUSIONS Bariatric surgery is associated with an increased risk of self-harm, mainly in relation to preexisting psychological conditions. Vigilance and appropriate care are thus warranted in vulnerable individuals.

Abstract
BACKGROUND Obesity is a known risk factor for many cancers. Although bariatric surgery has been associated with a decrease in the risk of developing cancer, data on the effect of bariatric surgery on female-specific cancers are limited. This study aimed to assess the impact of bariatric interventions on the development of endometrial, ovarian and breast cancer. METHODS The New York Statewide Planning and Research Cooperative System database was used to identify all female patients without a pre-existing cancer diagnosis who had a diagnosis of obesity between 2006 and 2012. The risk of having female-specific cancer diagnosis in patients who underwent bariatric surgery were compared with those who had no bariatric interventions using multivariable proportional sub-distribution hazard regression analysis. Subsequent cancer diagnoses were followed up to 2016. RESULTS We identified 55,781 and 247,102 obese female patients who had and did not have bariatric surgery, respectively. The overall incidence of female-specific cancer was 2.69% and 2.09% for the non-surgery and surgery groups, respectively (p < 0.0001). Surgery patients were less likely to develop female-specific cancers [hazard ratio (HR) 0.78; 95% CI 0.73-0.83; p < 0.0001]. Patients undergoing Roux-en-Y gastric bypass had a lower risk of developing female-specific cancer than laparoscopic sleeve gastrectomy (HR 0.66; 95% CI 0.51-0.87; p = 0.0056) and laparoscopic adjustable gastric banding (HR 0.83; 95% CI 0.69-0.99; p = 0.0056) patients. CONCLUSIONS Patients undergoing bariatric surgery have a lower incidence of endometrial, female breast and ovarian cancer than non-surgery obese patients. These data suggest that bariatric interventions may reduce the risk of female-specific cancers.

Abstract
OBJECTIVE To review the evidence and provide recommendations for the counselling and management of obese parturients. OUTCOMES Outcomes evaluated include the impact of maternal obesity on the provision of antenatal and intrapartum care, maternal morbidity and mortality, and perinatal morbidity and mortality. EVIDENCE Literature was retrieved through searches of Statistics Canada, Medline, and The Cochrane Library on the impact of obesity in pregnancy on antepartum and intrapartum care, maternal morbidity and mortality, obstetrical anaesthesia, and perinatal morbidity and mortality. Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to April 2009. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The evidence obtained was reviewed and evaluated by the Maternal Fetal Medicine and Clinical Practice Obstetric Committees of the SOGC under the leadership of the principal authors, and recommendations were made according to guidelines developed by the Canadian Task Force on Preventive Health Care. BENEFITS, HARMS, AND COSTS Implementation of the recommendations in this guideline should increase recognition of the issues clinicians need to be aware of when managing obese women in pregnancy, improve communication and consultation amongst the obstetrical care team, and encourage federal and provincial agencies to educate Canadians about the values of entering pregnancy with as healthy a weight as possible.

Abstract
SETTING Private clinic, Stockholm, and nation-wide in-hospital care, Sweden. OBJECTIVES The use of sleeve gastrectomy (SG) for treatment of morbid obesity has increased worldwide, but information about long-term outcome is still limited. Our objective was to evaluate the need for additional in-hospital care after SG for obesity (body mass index [BMI] > 30) in 862 patients, all operated at a single center. METHODS Two national registries, the Inpatient Registry and the Death Registry, were used to collect long-term data on in-hospital care, grouped by the International Statistical Classification of Diseases and Related Health Problems (ICD-10) and mortality, respectively. RESULTS In-hospital care for SG-operated females was decreased for four groups of obesity-related ICD-10 diagnoses: endocrine and metabolic diseases and circulatory, digestive, and genitourinary diseases, as well as injuries and poisoning (p < 0.001 for all). However, female SG patients still required in-hospital care above the national level for women of corresponding ages. CONCLUSIONS Although a significant reduction in in-hospital care was observed, SG patients did not reach national levels.

Abstract
INTRODUCTION Female sexual dysfunction (FSD) among the obese women is often under diagnosed and ignored especially in Malaysia, a nation of conservative multiethnic society. There are only a few studies on FSD resolution post-bariatric surgery. The objective was to identify the rate and resolution or improvement of FSD, among obese multiethnic Malaysian women post-bariatric surgery. MATERIAL AND METHODS This is a prospective study of women undergoing bariatric surgery, between May 2017 and April 2018. FSD was diagnosed using the Malay version of Female Sexual Function Index (MVFSFI) questionnaire. Patients filled up the questionnaire before and 6 months after surgery. Association between BMI reduction and FSFI score improvement was measured using Fisher's exact test. Outcomes between types of surgery (sleeve gastrectomy and gastric bypass) was compared. RESULTS Fifty-two women completed the study. The mean age was 38.77 ± 6.7. There were 44 (84.6%) Malay patients, 7 (13.5%) Indian patients, and 1 (1.9%) Chinese patient. There was a significant reduction in mean BMI, 39.89 ± 6.9 pre-surgery to 30.32 ± 5.4 post-surgery (p value < 0.001). The rate of FSD among the obese is 75.0% pre-surgery compared to 36.0% post-surgery. There was a significant improvement in mean FSFI score pre- and post-surgery: 18.73 and 25.93 respectively and in each of all 6 domains (p value < 0.001). There was a significant association between BMI reduction and improvement in FSFI score (p = 0.019). There was no difference in outcomes between types of surgery. CONCLUSION FSD is highly prevalent among the obese multiethnic Malaysian women. Bariatric surgery has proven benefit in resolving FSD across all sexual domains and should be considered as a management option in this group of women.

Abstract
Background Conservative obesity treatment often leads to limited results. Bariatric surgery is highly efficient, but the candidates are at risk of developing perioperative complications. Bariatric outcomes have been well described in the past, but there are only few reports of perioperative outcomes. The aim of this study was to evaluate the incidence of anaesthetic and surgical complications of Roux-en-Y bypass. Methods Data of all adult patients, who underwent primary Roux-en-Y gastric bypass surgery between 1/2006 and 12/2013 at the University Hospital Zurich were analysed. Using our clinical database, anaesthetic and surgical complications during the first 30 days after surgery were analysed and risk factors determined by multivariate analysis. Results Seven hundred eleven patients (72% female, median age 40 years) were analysed. Overall, surgical complications occurred in 34% patient, while complications attributable to anaesthesia occurred in 37%. Post-operative nausea and vomiting (PONV) were observed in 34%, intubation-related complications in 4%, and delayed extubation in 2% of our patients. Within the first 30 days after surgery, 22% of the patients presented with an infection. Gastrointestinal complications were found in 8%, and bleeding complications in 3%. Anaesthesia complications were less common in older patients and in patients anaesthetized with a volatile anaesthetic. Severe complications were more common in patients with a lower body mass index (BMI) and with longer surgery. The risk to develop a postoperative infection was higher in diabetic patients. Conclusion Roux-en-Y bariatric surgery has few anaesthetic complications, the most common is PONV. PONV is more common in younger patients and not more common with volatile anaesthetics. Major complications are overall rare and occur in patients with lower BMI and longer surgery, likely reflecting more difficult procedures.

Abstract
BACKGROUND Bariatric surgery patients with mental illness may experience worse surgical outcomes compared to those without. Depression is the most prevalent mental health diagnosis amongst Americans with obesity. Accurate diagnosis and treatment is of paramount importance to mitigate perioperative risk. Unfortunately, there is no standard method to screen patients for depression prior to surgery. Our goal was to understand the relationship between traditional clinical screening tools and a novel patient-reported depression screening survey, Patient Health Questionnaire 8 (PHQ-8), in the setting of the bariatric surgery preoperative assessment. METHODS The study included all adult bariatric surgery patients from January 2014 through June 2016. Patients who were not assessed using both the PHQ-8 and a traditional clinical depression screening were excluded from the study. There were a total of 4486 patients who met the eligibility criteria and were included in analysis. We used comparative statistics to examine the association between these screening tools and to test for contributing demographic, surgical, and socioeconomic factors. RESULTS The overall rate of clinically diagnosed depression in the study cohort was 45.6%. In comparison, 14.8% of all patients screened positive for depression using the PHQ-8. Of the patients without a traditional clinical diagnosis of depression, 10.2% screened positive for depression using the PHQ-8. This subset of undiagnosed patients was more likely to be non-white, employed, and had a higher BMI than their clinically diagnosed counterparts. CONCLUSIONS AND RELEVANCE We found a higher rate of clinically diagnosed depression in our cohort compared to the general population. However, when using the validated PHQ-8 survey, the rate of depression more closely approximated the national incidence. Further, a significant proportion of patients were undiagnosed and/or misdiagnosed by current clinical assessments. Standardizing preoperative depression screening using validated patient-centered tools may prevent the consequences of untreated depression.

Abstract
BACKGROUND An increasing number of people require help to manage their weight. The NHS recommends weight loss advice by general practitioners and/or a referral to a practice nurse. Although this is helpful for some, more effective approaches that can be disseminated economically on a large scale are needed. OBJECTIVE To assess whether or not a task-based weight management programme [Weight Action Programme (WAP)] has better long-term effects than a 'best practice' intervention provided in primary care by practice nurses. DESIGN Randomised controlled trial with cost-effectiveness analysis. SETTING General practices in east London, UK. PARTICIPANTS Three hundred and thirty adults with a body mass index (BMI) of ≥ 30 kg/m2 or a BMI of ≥ 28 kg/m2 plus comorbidities were recruited from local general practices and via media publicity. Those who had a BMI of > 45 kg/m2, had lost > 5% of their body weight in the previous 6 months, were currently pregnant or taking psychiatric medications were excluded. Participants were randomised (2 : 1) to the WAP or nurse arms. INTERVENTIONS The WAP intervention was delivered in eight weekly group sessions that combined dietary and physical activity, advice and self-monitoring in a group-oriented intervention. The initial course was followed by 10 monthly group maintenance sessions open to all participants in this study arm. The practice nurse intervention (best usual care) consisted of four one-to-one sessions delivered over 8 weeks, and included standard advice on diet and physical activity based on NHS 'Change4Life' materials and motivational support. MAIN OUTCOME MEASURES The primary outcome measure was weight change at 12 months. Secondary outcome measures included change in BMI, waist circumference and blood pressure, and proportion of participants losing at least 5% and 10% of baseline body weight. Staff collecting measurements at the 6- and 12-month follow-ups were blinded to treatment allocation. The primary outcome measure was analysed according to the intention-to-treat principle, and included all participants with at least one recorded outcome at either 1, 2, 6 or 12 months. The analysis employed a mixed-effects linear regression model, adjusted for baseline weight, age, sex, ethnicity, smoking status and general practice. The European Quality of Life-5 Dimensions-5 Levels questionnaire was completed and used to estimate quality-adjusted life-years (QALYs) within the cost-effectiveness analysis. RESULTS There were 330 participants (WAP arm, n = 221; nurse arm, n = 109; 72% women). A total of 291 (88%) participants (WAP arm, n = 194; nurse arm, n = 97) were included in the main analysis for the primary outcome. Weight loss at 12 months was greater in the WAP arm than in the nurse intervention arm [-4.2 kg vs. -2.3 kg; difference -1.9 kg, 95% confidence interval (CI) -3.7 to -0.1 kg; p = 0.04]. Participants in the WAP arm were more likely than participants in the nurse arm to have lost at least 5% of their baseline body weight at 12 months (41% vs. 27%; odds ratio 14.61, 95% CI 2.32 to 91.96; p = 0.004). The incremental cost-effectiveness ratio for WAP over and above the nurse arm is £7742 per QALY. CONCLUSIONS A WAP delivered in general practice better promotes weight loss over 12 months than a best usual practice nurse-led weight loss programme. LIMITATIONS The trial recruited mostly women. Research is needed into factors that would make weight loss programmes more attractive to men. TRIAL REGISTRATION Current Controlled Trials ISRCTN45820471.

Abstract
Background Concerns for the possibility of an excessive loss of fat-free mass (FFM) and resting metabolic rate (RMR) after bariatric surgery, such as Roux-en-Y gastric bypass (RYGB) and duodenal switch (BPD/DS), have been raised. Objectives This study aims to examine body composition and RMR in patients after RYGB and BPD/DS and in non-operated controls. Methods Body composition and RMR were studied with Bod Pod and indirect calorimetry in weight-stable RYGB (n = 15) and BPD/DS patients (n = 12) and compared with non-operated controls (n = 17). All patients were 30–55 years old and weight stable with BMI 28–35 kg/m2. Results FFM% was 58% (RYGB), 61% (BPD/DS), and 58% (controls). Body composition did not differ after RYGB and BPD/DS compared to controls, despite 27 and 40% total body weight loss, respectively. No difference in RMR or RMR/FFM was observed (1539, 1617, and 1490 kcal/24 h; and 28.9, 28.4, and 28.8 kcal/24 h/kg). Conclusion Weight-stable patients with BMI 28–35 kg/m2 after RYGB and BPD/DS have a body composition and RMR similar to that of non-operated individuals within the same BMI interval.

Abstract
This is the first systematic review to synthesize the evidence concerning early post-operative variables predictive of later weight and psychosocial outcomes in bariatric surgery. Eight electronic databases for empirical studies were searched (1954 to 2016). Most of the 39 included studies reported solely on weight outcomes; eating and psychosocial outcomes were less common. A better early weight loss trajectory was the most consistent predictor of more successful medium-term weight outcome (≤24 months); however, its relationship to longer term weight loss maintenance is less certain. Early eating adaptation may be associated with later weight loss, but further research is needed. Evidence is lacking for associations between early adherence or early psychosocial variables and later outcome. In particular, the relationship between early post-operative depression and later weight remains unclear. Little research has considered early prediction of later eating or psychosocial outcomes. Consideration of mediating or moderating relationships is lacking. The body of evidence is limited, and synthesis is hampered by heterogeneity in the type and time at which predictors and outcomes are measured and quality of statistical reporting. Further research on prospective prediction of bariatric surgery outcome is needed to guide early post-operative intervention for those at greatest risk of poor outcomes.

Abstract
Total knee replacement (TKR) comprises a significant, growing aspect in the management of patients with advanced arthritis of the knee for which conservative medical therapy has failed. Obesity, a rising epidemic, is considered an important independent risk factor in the development of osteoarthritis (OA). An aging population and increasing incidence of obesity contribute to a higher prevalence of OA and a subsequent greater need for TKR. The numbers of morbidly obese (MO) people undergoing TKR has consistently been rising. However, there have been concerns among patients and surgeons about the outcomes and complications of TKR in MO patients, especially given the morbidities associated with obesity. The goal of this systematic review was to assess relevant, up-to-date data on the safety, outcomes, and complications associated with TKR in MO patients.

Abstract
Difficulties in setting healthcare priorities are encountered throughout the world. There is no agreement on the most appropriate principles or methods for healthcare rationing although there is some consensus that it should be undertaken as systematically and accountably as possible. Although some steps towards achieving accountability have been made at the macro and meso level, at the consultation level rationing remains implicit and poorly understood. Using morbid obesity surgery as a case study, we observed a series of UK National Health Service consultations where rationing was ongoing and conducted in-depth interviews with doctors and patients (2011-2014). A longitudinal approach was taken to research and in total 22 consultations were observed and 78 interviews were undertaken. Sampling was undertaken purposively and theoretically and analyses were undertaken thematically. Clinicians needed to prioritise 55 patients from 450 eligible referrals, but disagreed over the extent to which clinical and financial factors were the driving force behind decision-making. The most prominent rationing technique observed in consultations was rationing by selection, but examples of rationing by delay, by deterrence, and by deflection were also commonplace. Although all clinicians sought to avoid rationing by denial, only six of the 22 patients recruited to the research were known to have been treated at the end of the three-year period. Most clinicians sought to manage rationing implicitly, and only one explained the link between decision-making criteria and financial constraints on care availability. Although existing frameworks for categorising NHS rationing techniques were useful in identifying implicit strategies, in practice these techniques over-lapped substantially and we have proposed a simpler framework for analysing NHS rationing decisions at the consultation level, which includes just three categories - rationing by exclusion, rationing by deterrence, and rationing by delay.

Abstract
Sleeve gastrectomy (SG) is a surgical weight-loss procedure. Splenic abscess is a rare complication of SG. Four cases of splenic abscess after SG have been reported, all managed by surgical intervention. We report the first documented case of multiple splenic abscesses following SG managed conservatively by an integrated medical treatment.

Abstract
Intragastric balloon (IGB) is one of the available options for the management of morbid obesity. The procedure is generally safe and of moderate efficacy in most of the cases. One of the reported complications of IGB is gastric perforation. The management of this complication is classically surgical. To our knowledge, conservative management for gastric perforation secondary to IGB has not been reported. A 27-year-old female patient presented with sudden abdominal pain in the left upper quadrant, 2 months after having an IGB placed. The provisional diagnosis was gastric perforation. Balloon extraction was performed and a conservative management of the gastric perforation was pursued successfully. We therefore propose that this sort of management might be adopted in carefully selected cases.

Abstract
INTRODUCTION In 2013 the Department of Health specified eligibility for bariatric surgery funded by the National Health Service. This included a mandatory specification that patients first complete a Tier 3 medical weight management programme. The clinical effectiveness of this recommendation has not been evaluated previously. Our bariatric centre has provided a Tier 3 programme six months prior to bariatric surgery since 2009. The aim of our retrospective study was to compare weight loss in two cohorts: Roux-en-Y gastric bypass only (RYGB only cohort) versus Tier 3 weight management followed by RYGB (Tier 3 cohort). METHODS A total of 110 patients were selected for the study: 66 in the RYGB only cohort and 44 in the Tier 3 cohort. Patients in both cohorts were matched for age, sex, preoperative body mass index and pre-existing co-morbidities. The principal variable was therefore whether they undertook the weight management programme prior to RYGB. Patients from both cohorts were followed up at 6 and 12 months to assess weight loss. RESULTS The mean weight loss at 6 months for the Tier 3 cohort was 31% (range: 18-69%, standard deviation [SD]: 0.10 percentage points) compared with 23% (range: 4-93%, SD: 0.12 percentage points) for the RYGB only cohort (p=0.0002). The mean weight loss at 12 months for the Tier 3 cohort was 34% (range: 17-51%, SD: 0.09 percentage points) compared with 27% (range: 14-48%, SD: 0.87 percentage points) in the RYGB only cohort (p=0.0037). CONCLUSIONS Our study revealed that in our matched cohorts, patients receiving Tier 3 specialist medical weight management input prior to RYGB lost significantly more weight at 6 and 12 months than RYGB only patients. This confirms the clinical efficacy of such a weight management programme prior to gastric bypass surgery and supports its inclusion in eligibility criteria for bariatric surgery.

Abstract
Background Roux-en-Y gastric bypass (RYGBP) and sleeve gastrectomy (SG) are the most common bariatric procedures undertaken globally but there are no evidenced-based criteria that inform the selection of one operation over the other. The purpose of this study was thus to compare weight loss outcomes between RYGBP and SG, and to define patient factors affecting weight loss. Methods A single-centre two-year follow-up retrospective cohort study of all adults who underwent either RYGBP (n = 422) or SG (n = 432) between 2007 and 2012, at University College London Hospitals National Health Service Foundation Trust, an academic tertiary referral centre, was undertaken. Multilevel linear regression was used to compare weight loss between groups, enabling adjustment for preoperative BMI (body mass index) and evaluation for interaction factors. Results One- and two-year results showed that unadjusted BMI loss was similar between groups; 13.7 kg/m2 (95% CI: 12.9, 14.6 kg/m2) and 12.8 kg/m2 (95% CI: 11.8, 13.9 kg/m2) for RYGBP patients respectively compared with 13.3 kg/m2 (95% CI: 12.0, 14.6 kg/m2) and 11.5 kg/m2 (95% CI: 10.1, 13.0 kg/m2) for SG patients respectively. Adjusting for preoperative BMI, there was 2.2 kg/m2 (95% CI: 1.5, 2.8) and 2.3 kg/m2 (95% CI: 1.3, 3.3) greater BMI loss in the RYGBP group compared to the SG group at one and two years respectively (P < 0.001 for both). The interaction analyses demonstrated that age and sex had important differential impacts on SG and RYGBP weight outcomes. Men under 40 and women over 50 years obtained on average far less benefit from SG compared to RYGBP, whereas men over 40 years and women under 50 years experienced similar weight loss with either procedure (P = 0.001 and 0.022 for interaction effects at one and two years respectively). Conclusions Our results show that patient sex and age significantly impact on weight loss in a procedure-dependent manner and should be considered when choosing between RYGBP and SG. Optimizing procedure selection could enhance the effectiveness of bariatric surgery, thus further increasing the benefit-to-risk ratio of this highly effective intervention.

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.

Development of an Evidence-Based mHealth Weight Management Program Using a Formative Research Process. JMIR Mhealth Uhealth 2014; 2:e18. [PMID: 25098337 PMCID: PMC4125156 DOI: 10.2196/mhealth.2850] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2013] [Revised: 11/17/2013] [Accepted: 12/14/2013] [Indexed: 12/22/2022] Open
Abstract
Background There is a critical need for weight management programs that are effective, cost efficient, accessible, and acceptable to adults from diverse ethnic and socioeconomic backgrounds. mHealth (delivered via mobile phone and Internet) weight management programs have potential to address this need. To maximize the success and cost-effectiveness of such an mHealth approach it is vital to develop program content based on effective behavior change techniques, proven weight management programs, and closely aligned with participants’ needs. Objective This study aims to develop an evidence-based mHealth weight management program (Horizon) using formative research and a structured content development process. Methods The Horizon mHealth weight management program involved the modification of the group-based UK Weight Action Program (WAP) for delivery via short message service (SMS) and the Internet. We used an iterative development process with mixed methods entailing two phases: (1) expert input on evidence of effective programs and behavior change theory; and (2) target population input via focus group (n=20 participants), one-on-one phone interviews (n=5), and a quantitative online survey (n=120). Results Expert review determined that core components of a successful program should include: (1) self-monitoring of behavior; (2) prompting intention formation; (3) promoting specific goal setting; (4) providing feedback on performance; and (5) promoting review of behavioral goals. Subsequent target group input confirmed that participants liked the concept of an mHealth weight management program and expressed preferences for the program to be personalized, with immediate (prompt) and informative text messages, practical and localized physical activity and dietary information, culturally appropriate language and messages, offer social support (group activities or blogs) and weight tracking functions. Most target users expressed a preference for at least one text message per day. We present the prototype mHealth weight management program (Horizon) that aligns with those inputs. Conclusions The Horizon prototype described in this paper could be used as a basis for other mHealth weight management programs. The next priority will be to further develop the program and conduct a full randomized controlled trial of effectiveness.

Abstract
Overweight and obesity have become a global health problem. Obesity and excessive weight gain during pregnancy have a serious impact on maternal, fetal and neonatal outcomes. Pre-conceptional obesity and excessive weight gain during pregnancy are associated with weight gain in women following childbirth leading to associated risks such as metabolic syndrome, cardiovascular disease and diabetes. Long-term risks for the offspring are an increased risk for early cardiovascular events, metabolic syndrome and decreased life expectancy as adults. German health care has not yet adequately responded to this development. There are no clinical guidelines for obesity before, during or after pregnancy, there are no concerted actions amongst midwives, obstetricians, health advisors, politicians and the media. Research projects on effective interventions are lacking although health care concepts would be urgently needed to reduce future metabolic and cardiovascular risks for women and children as well as to minimize the associated costs for the society.

Abstract
Long-term weight loss after Roux-en-Y gastric bypass (RYGB) in super-obese patients has not been ideal. Biliopancreatic diversion with duodenal switch (DS) is argued to be better; however, additional side effects are feared. The aim of the present study was to determine differences in results after DS and RYGB in publications from single-centre comparisons. A systematic review of studies containing DS and RYGB performed at the same centre was performed. Outcome data were weight results, resolution of comorbid conditions, perioperative results and complications. Main outcome was difference in weight loss after DS and RYGB. Secondary outcomes were difference in resolution of comorbidities, perioperative results and complications. The final analysis included 16 studies with in total 874 DS and 1,149 RYGB operations. When comparing weight results at the longest follow-up of each study, DS yielded 6.2 (95% confidence interval 5.0-7.5) body mass index units additional weight loss compared with RYGB, P < 0.001. Operative time and length of stay were significantly longer after DS, as well as the risk for post-operative leaks, P < 0.05. DS is more effective than RYGB as a weight-reducing procedure. However, this comes at the price of more early complications and might also yield slightly higher perioperative mortality.

Abstract
BACKGROUND Identifying factors that influence weight loss after bariatric surgery is one way to predict a successful surgical outcome. Knowledge of the effect of gender on weight loss after bariatric surgery has not been well demonstrated in the literature despite being noted in every day practice. The aim of this study was to find the influence of gender on long-term weight loss after bariatric surgery. METHODS A retrospective analysis of data retrieved from a prospectively maintained bariatric database was conducted. RESULTS The study included 640 consecutive patients. Their mean age was 38 ± 10 years, mean preoperative body mass index was 44.9 ± 8.4 kg/m2, and mean preoperative excess weight (EW %) was 108.3 ± 38.4%. The mean of the average excess weight loss (EWL %) was 43.3 ± 42.4%. Three procedures were utilized: Roux-en-Y gastric bypass (RYGB), vertical banded gastroplasty (VBG), and gastric banding (GB). Both VBG and RYGB induced significantly more EWL % than GB (d = 22.1%, p < 0.001 and d = 16, p = 0.02, respectively). In patients who underwent VBG and GB, males had significantly lower preoperative EW % (Student t = -4.86, p < 0.001, and Student t = 4.69, p < 0.001, respectively), and postoperative mean of the average EWL % (Student t = -2.43, p = 0.016, and Student t = -3.33, p = 0.002, respectively) than females. In patients who underwent RYGB, there were no differences in the preoperative EW % (t = -1.03, p = 0.309) or the mean of the average EWL % (t = 0.406, p = 0.688). The simple linear regression model used to explain the variability in EWL %, accounted for by the variability in the preoperative EW %, was significant (F = 180, p < 0.001). Analysis of the residual errors in predicting the EWL % revealed no significant difference between males and females after VBG and after RYGB (t = 0.117, p = 0.907 and t = 1.052, p = 0.3, respectively), while it was significant after GB (t = -2.999, p = 0.003). CONCLUSION From our experience, we suggest that GB not to be offered as a first choice for obese male patients.

Abstract
Obesity is commonplace, and surgical treatment usually includes Roux-en-Y gastric bypasses (RYGBs). RYGBs have the most documented side effects including vitamin deficiencies, rebound weight gain, and symptomatic hypoglycemia; fewer series exist describing hypoglycemia following other bariatric operations. We reviewed all patients undergoing laparoscopic adjustable gastric banding (LAGB) at our institution between 2008 and 2012. Three patients were identified to have symptomatic hypoglycemia following LAGB. Mean time from surgery was 33 months (range 14–45 months), and mean weight loss was 32.7 kg (range 15.9–43.1 kg). None of the patients had preexisting diabetes. Therefore, symptomatic hypoglycemia should be investigated irrespective of bariatric operation.

Abstract
BACKGROUND Laparoscopic adjustable gastric banding (LAGB) has been a widely performed bariatric procedure. Unfortunately, revisional surgery is required in 20-30% of cases. Data comparing revisional and primary gastric bypass procedures are scarce. This study compared revisional malabsorptive laparoscopic very very long limb (VVLL) Roux-en-Y gastric bypass (RYGB) with primary VVLL RYGB and tested the hypothesis that one-stage revisional laparoscopic VVLL RYGB is an effective procedure after failed LAGB. METHODS In this study, 48 revisional VVLL RYGBs were matched one-to-one with 48 primary VVLL RYGBs. The outcome measures were operating time, conversion to open surgery, excess weight loss (EWL), and early and late morbidity. RESULTS Surgical and medical morbidities did not differ significantly. No conversions occurred. The revisional group showed an EWL of 41.8% after 12 months of follow-up evaluation and 45.1% after 24 months based on the pre-revisional weight. The total EWL based on the weight before the LAGB was calculated to be 54.3% after 12 months and 57.2% after 24 months. The EWL in the primary RYGB group was significantly higher for both types of calculation: 41.8%/54.3% versus 64.1 % (p < 0.001 and <0.01) after 12 months and 45.1%/57.2% versus 70.4% (p < 0.001 and <0.002) after 24 months. CONCLUSIONS Revisional laproscopic VVLL RYGB can be performed as a one-stage procedure by experienced bariatric surgeons but shows less effective EWL than primary RYGB procedures.

Abstract
BACKGROUND Biliopancreatic diversion with duodenal switch, BPD-DS, is a surgical procedure for treatment of super obese patients. It renders very good weight results and it strongly reduces the incidence of type 2 diabetes. One important mechanism of weight reduction after BPD-DS is malabsorption. Hypomagnesemia is an established cardiovascular risk factor. While it is well-known that magnesium levels decline after jejuno-ileal bypass and increase after gastric bypass surgery, information on how magnesium status is affected by BPD-DS is scant. The aim of the present study was to evaluate plasma magnesium concentrations (P-Mg) after BPD-DS. METHODS Thirty-one patients, all Caucasians (9 diabetics, 12 men, age 38 ± 8 years, weight 159 ± 22 kg, body mass index (BMI) 53.9 ± 5.2 kg/m(2)) underwent BPD-DS. We evaluated weight, glycated hemoglobin levels (HbA1c) and P-Mg preoperatively as well as at 1 and 3 years after surgery. All subjects were treated with vitamin and mineral substitution after surgery, including 100 mg of magnesium salt. P-Mg was analyzed with respect to changes over time, correlation to BMI and HbA1c levels before and 3 years after surgery. RESULTS The plasma magnesium concentrations increased by 15 % from 0.77 ± 0.07 to 0.88 ± 0.09 mmol/l over 3 years (p < 0.001). The weight loss was 71 ± 25 kg. No patient had diabetes at follow-up. No correlations between P-Mg and BMI or HbA1c were seen. CONCLUSIONS Although exerting much of its weight-reducing effect by a malabsorptive mechanism, BPD-DS yields a rise in P-Mg 3 years postoperatively, possibly contributing to the improved metabolic state after this operation.

Abstract
Background There is little robust evidence relating to changes in health related quality of life (HRQL) in morbidly obese patients following a multidisciplinary non-surgical weight loss program or laparoscopic Roux-en-Y Gastric Bypass (RYGB). The aim of the present study was to describe and compare changes in five dimensions of HRQL in morbidly obese subjects. In addition, we wanted to assess the clinical relevance of the changes in HRQL between and within these two groups after one year. We hypothesized that RYGB would be associated with larger improvements in HRQL than a part residential intensive lifestyle-intervention program (ILI) with morbidly obese subjects. Methods A total of 139 morbidly obese patients chose treatment with RYGB (n=76) or ILI (n=63). The ILI comprised four stays (seven weeks) at a specialized rehabilitation center over one year. The daily schedule was divided between physical activity, psychosocially-oriented interventions, and motivational approaches. No special diet or weight-loss drugs were prescribed. The participants completed three HRQL-questionnaires before treatment and 1 year thereafter. Both linear regression and ANCOVA were used to analyze differences between weight loss and treatment for five dimensions of HRQL (physical, mental, emotional, symptoms and symptom distress) controlling for baseline HRQL, age, age of onset of obesity, BMI, and physical activity. Clinical relevance was assessed by effect size (ES) where ES<.49 was considered small, between .50-.79 as moderate, and ES>.80 as large. Results The adjusted between group mean difference (95% CI) was 8.6 (4.6,12.6) points (ES=.83) for the physical dimension, 5.4 (1.5–9.3) points (ES=.50) for the mental dimension, 25.2 (15.0–35.4) points (ES=1.06) for the emotional dimension, 8.7 (1.8–15.4) points (ES=.37) for the measured symptom distress, and 2.5 for (.6,4.5) fewer symptoms (ES=.56), all in favor of RYGB. Within-group changes in HRQOL in the RYGB group were large for all dimensions of HRQL. Within the ILI group, changes in the emotional dimension, symptom reduction and symptom distress were moderate. Linear regression analyses of weight loss on HRQL change showed a standardized beta-coefficient of –.430 (p<.001) on the physical dimension, –.288 (p=.004) on the mental dimension, –.432 (p<.001) on the emotional dimension, .287 (p=.008) on number of symptoms, and .274 (p=.009) on reduction of symptom pressure. Conclusions Morbidly obese participants undergoing RYGB and ILI had improved HRQL after 1 year. The weaker response of ILI on HRQL, compared to RYGB, may be explained by the difference in weight loss following the two treatments. Trial registration Clinical Trials.gov number NCT00273104

Abstract
BACKGROUND A systematic review and economic evaluation was commissioned to determine the effectiveness and cost-effectiveness of bariatric surgery for mild [class I, body mass index (BMI) 30 to 34.99] or moderate (class II, BMI 35 to 39.99) obesity. METHODS We searched 17 electronic resources (to February 2010) and other sources. Studies meeting predefined criteria were identified, data-extracted and assessed for risk of bias using standard methodology. A model was developed to estimate cost-effectiveness. RESULTS Two RCTs were included. Evidence from both indicated a statistically significant benefit from laparoscopic adjustable banding (LAGB) compared to a non-surgical comparator for weight loss and in obesity-related comorbidity. Both interventions were associated with adverse events. LAGB costs more than non-surgical management. For people with class I or II obesity and type 2 diabetes (T2D), the incremental cost-effectiveness ratio (ICER) at 2 years is £20,159, reducing to £4,969 at 5 years and £1,634 at 20 years. Resolution of T2D makes the greatest contribution to this reduction. In people with class I obesity, the ICER is £63,156 at 2 years, £17,158 at 5 years, and £13,701 at 20 years. Cost-effectiveness results are particularly sensitive to utility gain from reduction in BMI, factors associated with poorer surgical performance and diabetes health state costs. CONCLUSIONS Bariatric surgery appears to be a clinically effective and cost-effective intervention for people with class I or II obesity who also have T2D but is less likely to be cost-effective for people with class I obesity.

Abstract
The upward trend in obesity prevalence across regions and continents is a worldwide concern. Today a majority of the world's population live in a country where being overweight or obese causes more deaths than being underweight. Only a portion of those qualifying for treatment will get the health care they need. Still, a minor weight loss of 5-10% seems to be sufficient to provide a clinically significant health benefit in terms of risk factors for cardiovascular disease and diabetes. Diet, exercise and behavior modifications remain the current cornerstones of obesity treatment. Weight-loss drugs play a minor role. Drugs which were available and reasonably effective have been withdrawn because of side effects. The fact that the 'old' well known, but pretty unexciting tools remain the basic armamentarium causes understandable concern and disappointment among both patients and therapists. Hence, bariatric surgery has increasingly been recognized and developed, as it offers substantial weight loss and prolonged weight control. The present review highlights the conventional tools to counter obesity, lifestyle modification, pharmacotherapy and bariatric surgery, including some of the barriers to successful weight loss: (1) unrealistic expectations of success; (2) high attrition rates; (3) cultural norms of self-acceptance in terms of weight and beliefs of fat being healthy; (4) neighborhood attributes such as a lack of well-stocked supermarkets and rather the presence of convenience stores with low-quality foods; and (5) the perception of the neighborhood as less safe and with low walkability. Prevention is the obvious key. Cost-effective societal interventions such as a tax on unhealthy food and beverages, front-of-pack traffic light nutrition labeling and prohibition of advertising of junk food and beverages to children are also discussed.

Abstract
Bariatric surgery for morbid obesity has been established as an effective treatment method and has been shown to be associated with resolution of co-morbidities. Despite its success, some patients may require revision because of weight regain or mechanical complications. From September 2005 to December 2009, 42 patients underwent revisional Roux-en-Y gastric bypass (RYGB). All procedures were performed by one surgeon. Demographics, indications for revision, complications, and weight loss were reviewed. Thirty-seven patients were treated with laparoscopic (n = 36) or open (n = 1) RYGB after failed laparoscopic adjustable gastric banding. Four patient were treated with laparoscopic (n = 3) or open (n-1) RYGB after failed vertical banded gastroplasty, and one patient underwent open redo RYGB due to large gastric pouch. Conversion rate from laparoscopy to open surgery was 2.5% (one patient). Mean operative time was 145.83 ± 35.19 min, and hospital stay was 3.36 ± 1.20 days. There was no mortality. Early and late complications occurred in six patients (14.2%). The mean follow-up was 15.83 ± 13.43 months. Mean preoperative body mass index was 45.15 ± 7.95 that decreased to 35.23 ± 6.7, and mean percentage excess weight loss was 41.19 ± 20.22 after RYGB within our follow-up period. RYGB as a revisional bariatric procedure is effective to treat complications of restrictive procedures and to further reduce weight in morbidly obese patients.

Use of self-expandable stents in the treatment of bariatric surgery leaks: a systematic review and meta-analysis. Gastrointest Endosc 2012; 75:287-93. [PMID: 22047699 DOI: 10.1016/j.gie.2011.09.010] [Citation(s) in RCA: 163] [Impact Index Per Article: 13.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2011] [Accepted: 09/07/2011] [Indexed: 12/11/2022]
Abstract
BACKGROUND Bariatric surgery leaks can result in significant morbidity and mortality. Endoscopic placement of self-expandable stents (SESs) is emerging as a less-invasive alternative to surgery for the treatment of leaks. OBJECTIVE To evaluate the success of SESs in the treatment of bariatric surgery leaks. DESIGN Studies using SESs in the management of bariatric surgery leaks were selected. Success of SES treatment was defined as radiographic evidence of leak closure after stent removal. Articles were searched in MEDLINE, PubMed, Ovid, and Cochrane Register of Controlled Trials. Pooled proportions were calculated by using fixed- and random-effects models. Publication bias was calculated by using the Begg-Mazumdar and Harbord bias estimators. RESULTS A total of 189 relevant articles were reviewed of which 7 studies (67 patients with leaks) met inclusion criteria. The pooled proportion of successful leak closures by using SESs was 87.77% (95% CI, 79.39%-94.19%). The pooled proportion of successful endoscopic stent removal was 91.57% (95% CI, 84.22%-96.77%). Stent migration was noted in 16.94% (95% CI, 9.32%-26.27%). Test of heterogeneity gave a P value >.10. There was no publication bias. LIMITATIONS Small retrospective studies, different types of stents used. CONCLUSION Endoscopic placement of SESs is a minimally invasive, safe, and effective alternative in the management of leaks after bariatric surgery. The use of SESs can minimize the need for surgical revision and improve patient outcomes.

Abstract
The gastrointestinal tract plays an important role in the improved appetite control and weight loss in response to bariatric surgery. Other strategies which similarly alter gastrointestinal responses to food intake could contribute to successful weight management. The aim of this review is to discuss the effects of surgical, pharmacological and behavioural weight loss interventions on gastrointestinal targets of appetite control, including gastric emptying. Gastrointestinal peptides are also discussed because of their integrative relationship in appetite control. This review shows that different strategies exert diverse effects and there is no consensus on the optimal strategy for manipulating gastric emptying to improve appetite control. Emerging evidence from surgical procedures (e.g. sleeve gastrectomy and Roux-en-Y gastric bypass) suggests a faster emptying rate and earlier delivery of nutrients to the distal small intestine may improve appetite control. Energy restriction slows gastric emptying, while the effect of exercise-induced weight loss on gastric emptying remains to be established. The limited evidence suggests that chronic exercise is associated with faster gastric emptying, which we hypothesize will impact on appetite control and energy balance. Understanding how behavioural weight loss interventions (e.g. diet and exercise) alter gastrointestinal targets of appetite control may be important to improve their success in weight management.

Abstract
BACKGROUND/AIM A prospective longitudinal study was conducted to describe short-term outcome and quality of life (QOL) of endoscopically placed gastric balloon (EPGB) and laparoscopic adjustable gastric band (LAGB). MATERIALS AND METHODS Forty seven consecutive patients with body mass index (BMI) of 42 to 72 kg/m² were assigned to undergo EPGB (n=17) or LAGB (n=30) between May 2008 and May 2010. The main measured outcomes included weight loss, resolution or improvement of comorbidities, hospital stay, complications and QOL. RESULTS Patients were followed up for a mean of 14 months. Hospital stay was shorter for EPGB patients (one versus two days, P<0.001). Early postoperative complications recorded in EPGB were minor including nausea and vomiting. No late complications were recorded in the EPGB group. One case of band slippage was reported in the LAGB group and fixed laparoscopically. Percent excess weight loss was less in EPGB compared to LAGB (26.2% versus 44.0%, P=0.004). Resolution or improvement of comorbidities was comparable in both groups. The globally impaired preoperative quality of life showed considerable improvement in both groups. CONCLUSION EPGB is a safe and effective approach in short-term management of morbid obesity. Weight loss, resolution of comorbidities and improvement in QOL were comparable between both groups.

Abstract
BACKGROUND Sleeve gastrectomy (SG) is a relatively new bariatric procedure with a number of advantages compared with Roux-en-Y gastric bypass. However, SG also has a number of disadvantages and associated risks. We sought to examine perioperative complications and outcomes of laparoscopic SG (LSG) in a single major Canadian bariatric surgery centre (Victoria, BC). METHODS Since June 2008, LSG has been performed at our centre and we reviewed the cases of all patients. We conducted a retrospective chart review in April 2010. RESULTS Thirty-four patients had LSG, and none was lost to follow-up. Indications for LSG over other bariatric procedures were patient preference (n=28), severe obesity with a body mass index (BMI) greater than 60 kg/m(2) (n=5) and severe upper abdominal adhesions (n=1). All but 1 of the cohort were women, and the average age was 48 (standard deviation [SD] 11) years. Preoperatively, the average BMI was 50.3 (SD 7.7) kg/m(2). Preoperative obesity-related comorbidity rates were 56% (n=19) for type 2 diabetes mellitus (T2DM), 50% (n=17) for hypertension, 32% (n=11) for dys lipidemia, 62% (n=21) for obstructive sleep apnea (OSA), 62% (n=21) for knee and/or hip pain and 44% (n=15) for depression and/or anxiety. The mean duration of surgery was 74 (SD 21) minutes. There were 2 major perioperative complications: 1 staple line leak and 1 staple line hemorrhage. The median stay in hospital was 1 day. Postoperative upper gastrointestinal imaging studies were conducted in 11 patients; 1 was positive for staple line leak. Histopathology on the excised gastric segments revealed chronic helicobacter pylori gastritis in 2 patients and small gastrointestinal stromal tumours in 1 patient. The mean postoperative follow-up interval was 10 months. Weight loss averaged 27.4 (SD 9.0) kg. Overall weight loss was 3.3 (SD 1.8) kg/month. Resolution occurred in 74% of patients with T2DM, 53% with hypertension, 45% with dyslipidemia, 76% with OSA, 38% with joint pain and 20% with depression/anxiety. Overall satisfaction was rated as excellent by 68% of patients, good by 29% and poor by 3% of patients. CONCLUSION Preliminary analysis of our experience with LSG indicates that this is an effective and safe procedure for the treatment of obesity.

Abstract
Laparoscopic adjustable gastric banding (LAGB) and vertical-banded gastroplasty (VBG) are surgical treatment modalities for morbid obesity. This prospective study describes the long-term results of LAGB and VBG. One hundred patients were included in the study. Fifty patients underwent LAGB and 50 patients, open VBG. Study parameters were weight loss, changes in obesity-related comorbidities, long-term complications, re-operations including conversions to other bariatric procedures and laboratory parameters including vitamin status. From 91 patients (91%), data were obtained with a mean follow-up duration of 84 months (7 years). Weight loss [percent excess weight loss (EWL)] was significantly more after VBG compared with LAGB, 66% versus 54%, respectively. All comorbidities significantly decreased in both groups. Long-term complications after VBG were mainly staple line disruption (54%) and incisional hernia (27%). After LAGB, the most frequent complications were pouch dilatation (21%) and anterior slippage (17%). Major re-operations after VBG were performed in 60% of patients. All re-operations following were conversions to Roux-en-Y gastric bypass (RYGB). In the LAGB group, 33% of patients had a refixation or replacement of the band, and 11% underwent conversion to another bariatric procedure. There were no significant differences in weight loss between patients with or without re-interventions. No vitamin deficiencies were present after 7 years, although supplement usage was inconsistent. This long-term follow-up study confirms the high occurrence of late complications after restrictive bariatric surgery. The failure rate of 65% after VBG is too high, and this procedure is not performed anymore in our institution. The re-operation rate after LAGB is decreasing as a result of new techniques and materials. Results of the re-operations are good with sustained weight loss and reduction in comorbidities. However, in order to achieve these results, a durable and complete follow-up after restrictive procedures is imperative.

Abstract
This systematic review evaluates the current evidence base for eating behavior changes after laparoscopic adjustable gastric banding (LAGB). A literature search from 1990 to February 2010 was conducted to identify original studies that assessed eating behavior in adults who have undergone LAGB. Sixteen articles (14 separate studies) met inclusion criteria. Although strength of the evidence base was limited by observational study designs and methodological weaknesses, results suggest that positive changes in eating behavior occur after surgery, including reduced over-eating in response to emotional and situational cues. There is some evidence to suggest that uncontrolled eating behaviors persist in some individuals, and that this may be problematic for weight loss after surgery. Few studies examined the relationship between changes in eating behavior and weight loss; thus, optimal behavioral strategies for promoting positive weight outcomes remain unclear. Further interventional research addressing the inherent limitations of the current-evidence base is required to guide development of evidence-based management guidelines for LAGB in future.

Abstract
BACKGROUND Medical treatment of obesity often fails, and surgical treatment, although successful, is aggressive. OBJECTIVE To evaluate the short-term safety and efficacy of an endoscopic restrictive implant procedure in the treatment of obesity. DESIGN Prospective, observational study. SETTING Tertiary-care referral hospital in The Netherlands. PATIENTS This study involved 13 patients with body mass indexes of between 40 and 50 kg/m(2) or between 35 and 40 kg/m(2) with obesity-related comorbidities. INTERVENTION A new transoral endoscopic restrictive implant procedure in the treatment of obesity. MAIN OUTCOME MEASUREMENTS Safety of the procedure, percentage of excess weight loss, change in body mass index. RESULTS In 1 patient, the procedure was abandoned after a gastric perforation related to stapler malfunctioning. In 2 patients, pneumoperitoneum was detected. This was desufflated with a percutaneous hollow needle in one patient and treated conservatively in the other. After these complications, technical adjustments were made in the procedure, and no subsequent procedural complications were seen. At 3 months postprocedure, patients obtained a median excess weight loss of 28%. Median body mass index decreased from 42.1 to 37.9 kg/m(2). LIMITATIONS Small number of patients. CONCLUSION Preliminary results of this transoral endoscopic restrictive implant system for the treatment of obesity showed successful placement in 12 of 13 patients. Procedural complications occurred in 3 patients. Weight loss was comparable to that of laparoscopic gastric band placement. Further long-term studies are under way.

Abstract
The cause of pseudotumor cerebri (PTC) is poorly understood although there is strong evidence that obesity plays a role in its development. This report describes a patient with medically intractable PTC, who had continued symptoms despite undergoing a ventriculo-peritoneal (VP) shunt. Following significant weight loss, as a result of laparoscopic gastric banding, she has been symptom free and off all medications for 11 months allowing VP shunt removal. Bariatric surgery should be strongly considered in morbidly obese patients with PTC.

Abstract
BACKGROUND This study aimed to assess the efficacy of laparoscopic adjustable gastric banding (LAGB) during a 6-year follow-up period. METHODS A retrospective database analysis of patients who underwent LAGB at New York University Medical Center between 1 January 2000 and 29 February 2008 was conducted. Patients were included for the efficacy analysis if they were 18 years old or older at the surgery date and had one or more visits with a recorded weight after surgery. Efficacy was assessed using percentage of excess weight loss (%EWL) at 1-year intervals after surgery. Missing weight values were interpolated using a cubic spline function. Linear regression models were used to assess the characteristics that affected the last available %EWL. All patients had implantation of the LAP-BAND system. RESULTS The inclusion criteria for the efficacy analysis were met by 2,909 patients. The majority of the patients were white (83.3%) and female (68.4%). The mean patient age was 44.6 years, and the mean baseline body mass index (BMI) was 45.3 kg/m2. The %EWL 3 years after surgery was 52.9%, which was sustained thereafter. In multivariate models, increased number of office visits, younger age, female gender, and Caucasian race were significantly associated with a higher maximum %EWL. CONCLUSIONS The LAP-BAND patients achieved a substantial and sustainable weight loss of approximately 50% at 6 years after surgery.

Abstract
OBJECTIVE To review the evidence and provide recommendations for the counselling and management of obese parturients. OUTCOMES Outcomes evaluated include the impact of maternal obesity on the provision of antenatal and intrapartum care, maternal morbidity and mortality, and perinatal morbidity and mortality. EVIDENCE Literature was retrieved through searches of Statistics Canada, Medline, and The Cochrane Library on the impact of obesity in pregnancy on antepartum and intrapartum care, maternal morbidity and mortality, obstetrical anaesthesia, and perinatal morbidity and mortality. Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to April 2009. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The evidence obtained was reviewed and evaluated by the Maternal Fetal Medicine and Clinical Practice Obstetric Committees of the SOGC under the leadership of the principal authors, and recommendations were made according to guidelines developed by the Canadian Task Force on Preventive Health Care. BENEFITS, HARMS, AND COSTS Implementation of the recommendations in this guideline should increase recognition of the issues clinicians need to be aware of when managing obese women in pregnancy, improve communication and consultation amongst the obstetrical care team, and encourage federal and provincial agencies to educate Canadians about the values of entering pregnancy with as healthy a weight as possible. RECOMMENDATIONS 1. Periodic health examinations and other appointments for gynaecologic care prior to pregnancy offer ideal opportunities to raise the issue of weight loss before conception. Women should be encouraged to enter pregnancy with a BMI < 30 kg/m(2), and ideally < 25 kg/m(2). (III-B). 2. BMI should be calculated from pre-pregnancy height and weight. Those with a pre-pregnancy BMI > 30 kg/m(2) are considered obese. This information can be helpful in counselling women about pregnancy risks associated with obesity. (II-2B). 3. Obese pregnant women should receive counselling about weight gain, nutrition, and food choices. (II-2B). 4. Obese women should be advised that they are at risk for medical complications such as cardiac disease, pulmonary disease, gestational hypertension, gestational diabetes, and obstructive sleep apnea. Regular exercise during pregnancy may help to reduce some of these risks. (II-2B). 5. Obese women should be advised that their fetus is at an increased risk of congenital abnormalities, and appropriate screening should be done. (II-2B). 6. Obstetric care providers should take BMI into consideration when arranging for fetal anatomic assessment in the second trimester. Anatomic assessment at 20 to 22 weeks may be a better choice for the obese pregnant patient. (II-2B). 7. Obese pregnant women have an increased risk of Caesarean section, and the success of vaginal birth after Caesarean section is decreased. (II-2B). 8. Antenatal consultation with an anaesthesiologist should be considered to review analgesic options and to ensure a plan is in place should a regional anaesthetic be chosen. (III-B). 9. The risk of venous thromboembolism for each obese woman should be evaluated. In some clinical situations, consideration for thromboprophylaxis should be individualized. (III-B).

Abstract
BACKGROUND The prevalence of obesity is increasing globally and will, if left unchecked, have major implications for both population health and costs to health services. OBJECTIVES To assess the effectiveness of strategies to change the behaviour of health professionals and the organisation of care to promote weight reduction in overweight and obese people. SEARCH STRATEGY We updated the search for primary studies in the following databases, which were all interrogated from the previous (version 2) search date to May 2009: The Cochrane Central Register of Controlled Trials (which at this time incorporated all EPOC Specialised Register material) (The Cochrane Library 2009, Issue 1), MEDLINE (Ovid), EMBASE (Ovid), CINAHL (EBSCO), and PsycINFO (Ovid). We identified further potentially relevant studies from the reference lists of included studies. SELECTION CRITERIA Randomised controlled trials (RCTs) that compared routine provision of care with interventions aimed either at changing the behaviour of healthcare professionals or the organisation of care to promote weight reduction in overweight or obese adults. DATA COLLECTION AND ANALYSIS Two reviewers independently extracted data and assessed study quality. MAIN RESULTS We included six RCTs, involving more than 246 health professionals and 1324 overweight or obese patients. Four of the trials targeted professionals and two targeted the organisation of care. Most of the studies had methodological or reporting weaknesses indicating a risk of bias.Meta-analysis of three trials that evaluated educational interventions aimed at GPs suggested that, compared to standard care, such interventions could reduce the average weight of patients after a year (by 1.2 kg, 95% CI -0.4 to 2.8 kg); however, there was moderate unexplained heterogeneity between their results (I(2) = 41%). One trial found that reminders could change doctors' practice, resulting in a significant reduction in weight among men (by 11.2 kg, 95% CI 1.7 to 20.7 kg) but not among women (who reduced weight by 1.3 kg, 95% CI -4.1 to 6.7 kg). One trial found that patients may lose more weight after a year if the care was provided by a dietitian (by 5.6 kg, 95% CI 4.8 to 6.4 kg) or by a doctor-dietitian team (by 6 kg, 95% CI 5 to 7 kg), as compared with standard care. One trial found no significant difference between standard care and either mail or phone interventions in reducing patients' weight. AUTHORS' CONCLUSIONS Most of the included trials had methodological or reporting weaknesses and were heterogeneous in terms of participants, interventions, outcomes, and settings, so we cannot draw any firm conclusions about the effectiveness of the interventions. All of the evaluated interventions would need further investigation before it was possible to recommend them as effective strategies.
