Abstract
Obesity has been identified as a significant factor contributing to the development of numerous cardiovascular conditions and as a result, the cardiovascular community has prioritized efforts to address obesity and reduce its associated risks. However, despite these efforts, the prevalence of obesity continues to rise steadily, and is projected to double in the upcoming years. Atrial fibrillation is among the most prevalent and extensively researched cardiovascular comorbidities associated with obesity. Several mechanisms have been postulated, including scar tissue formation and fat deposition, which ultimately leads to atrial remodeling and subsequent arrhythmogenesis. Numerous strategies have been implemented to prevent and manage obesity, encompassing lifestyle adjustments, dietary modifications, pharmacological treatments, and surgical interventions. Bariatric surgery has garnered significant recognition over the years due to its promising outcomes, including a decrease in the overall prevalence of atrial fibrillation and other cardiovascular comorbidities in general in obese patients. This study focuses on the current trends regarding the impact of bariatric surgery on obese patients with atrial fibrillation.

Abstract
Background Dumping syndrome is a frequent and wellknown adverse event after bariatric surgery and covers a dynamic spectrum of early and late dumping. Accelerated gastric emptying is generally considered to be the cause of gastrointestinal and vasomotor complaints. However, there is much uncertainty regarding the exact pathophysiology of dumping. It has been speculated that the syndrome is a desired consequence of bariatric surgery and contributes to more efficient weight loss, but supporting data are scarce. Methods A systematic search was conducted in PubMed in July-August 2021. The prevalence of dumping after the most frequently performed bariatric procedures was analyzed, as well as underlying pathophysiology and its role in weight reduction. Results Roux-en-Y gastric bypass (RYGB) is associated with the highest postoperative prevalence of dumping. The fast transit induces neurohumoral changes which contribute to an imbalance between postprandial glucose and insulin levels, resulting in hypoglycemia which is the hallmark of late dumping. Early dumping can, when received in a positive way, become a tool to maintain a strict dietary pattern, but no significant relationship to the degree of weight loss has been shown. However, late dumping is detrimental and promotes overall higher caloric intake. Conclusion Dumping syndrome is common after bariatric surgery, especially after RYGB. The pathophysiology is complex and ambiguous. Currently available data do not support dumping as a necessary condition to induce weight loss after bariatric surgery.

Long-term Outcomes of Transoral Outlet Reduction (TORe) for Dumping Syndrome and Weight Regain After Roux-en-Y Gastric Bypass. Obes Surg 2023; 33:1032-1039. [PMID: 36702981 PMCID: PMC10079715 DOI: 10.1007/s11695-023-06466-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 01/09/2023] [Accepted: 01/17/2023] [Indexed: 01/28/2023]
Abstract
BACKGROUND Both weight regain and dumping syndrome (DS) after Roux-en-Y gastric bypass (RYGB) have been related to the dilation of gastro-jejunal anastomosis. The aim of this study is to assess the safety and long-term efficacy of endoscopic transoral outlet reduction (TORe) for DS and/or weight regain after RYBG. MATERIALS AND METHODS A retrospective analysis was performed on a prospective database. Sigstad's score, early and late Arts Dumping Score (ADS) questionnaires, absolute weight loss (AWL), percentage of total body weight loss (%TBWL), and percentage of excess weight loss (%EWL) were assessed at baseline and at 6, 12, and 24 months after TORe. RESULTS Eighty-seven patients (median age 46 years, 79% female) underwent TORe. The median baseline BMI was 36.2 kg/m2. Out of 87 patients, 58 were classified as "dumpers" due to Sigstad's score ≥ 7. The resolution rate of DS (Sigstad's score < 7) was 68.9%, 66.7%, and 57.2% at 6, 12, and 24 months after TORe, respectively. A significant decrease in Sigstad's score as well as in early and late ADS questionnaires was observed (p < 0.001). The median Sigstad's score dropped from 15 (11-8.5) pre-operatively to 2 (0-12) at 24 months. The %TBWL was 10.5%, 9.9%, and 8.1% at 6, 12, and 24 months, respectively. Further, "dumpers" with resolution of DS showed better weight loss results compared with those with persistent DS (p < 0.001). The only adverse event observed was a perigastric fluid collection successfully managed conservatively. CONCLUSION TORe is a minimally invasive treatment for DS and/or weight regain after RYGB, with evidence of long-term efficacy.

Abstract
PURPOSE The Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is an effective weight loss procedure. The gastro-jejunal (GJ) anastomosis required can be performed on the anterior or posterior gastric pouch wall. No studies have compared these variants in terms of efficacy and onset of dumping syndrome (DS) and weight regain (WR). We aimed at assessing the prevalence of DS in relation to the site of anastomosis together with identifying prognostic factors of DS and WR. METHODS Patients who had undergone LRYGB with anterior (AGJ) or posterior (PGJ) anastomosis in 2010-2019 were retrospectively analyzed. We collected demographic data, medical history and the prevalence of DS evaluated through the Sigstad Score, together with WR data. RESULTS 213 patients were enrolled, of which 51.6% had an AGJ and 48.4% had a PGJ. The mean follow-up time was 81 ± 18 and 27 ± 13 months in the AGJ and PGJ group, respectively (p < 0.0001). Excess weight loss was 77.59% and 94.13% in patients with AGJ and PGJ, respectively (p < 0.001). WR rate was 16% and 4% in the AGJ and PGJ population, respectively (p < 0.001). DS prevalence was 38% and 76% in the AGJ and the PGJ population, respectively (p < 0.0001). The site of anastomosis was identified as an independent predictor of DS (OR5.15; 95% CI 2.82-9.41; p < 0.0001) and WR (OR5.31; 95% CI 2.32-12.15; p < 0.0001). Obesity-related complications significantly improved after surgery independent of the anastomosis site. CONCLUSION LRYGB is effective in determining long-term weight loss and improvement of complications. AGJ is associated with lower prevalence of DS but more frequent WR. The anastomosis site is a factor to be considered when performing LRYGB. LEVEL OF EVIDENCE Level V, cross-sectional descriptive study.

Abstract
Malnutrition and issues of nutrition are common in hospitalized patients. Identifying patients at nutritional risk can help to improve hospital-related outcomes. Specialized nutritional support in the form of oral nutritional supplementation, enteral nutrition, and parenteral nutrition is essential to meeting the nutritional needs of many patients. Disease-specific nutritional considerations are fundamental to the quality care of hospitalized patients. Many vitamin, macronutrient, and micronutrient deficiencies are relevant in hospital setting.

Abstract
BACKGROUND AND AIMS Metabolic surgery is gaining popularity as a procedure for the treatment of morbid obesity among patients with type 2 diabetes (T2DM). The aim of the study was to evaluate the effects of metabolic surgery on beta cell function, insulin sensitivity and glycemic status in obese Asian Indian patients. METHODS This is a prospective study of 26 patients with T2DM who underwent metabolic surgery. Complete diabetes remission was defined as FPG<100 mg/dl and HbA1c < 6%, without antidiabetic medications one-year post surgery. Anthropometry, HOMA-IR (insulin resistance), HOMA-insulin sensitivity, beta cell function and antidiabetic drug usage were measured at baseline, 6 months and 12 months post-surgery. RESULTS The overall duration of diabetes was 10.3 ± 5.4 years. At one year, 7 (27%) of 26 T2DM patients, achieved diabetes remission while the other 19 had improvement in diabetes status. ROC curves showed that those who had diabetes duration <8.5 years achieved remission. There was a significant decrease in HOMA-IR [3.7 ± 1.8 vs 1.4 ± 0.9 vs1.2 ± 0.6, p < 0.001] and improvement in HOMA-Insulin sensitivity [34 ± 17 vs 93 ± 50 vs 112 ± 62, p < 0.001] from baseline to 6 and 12 months post-surgery respectively. There was a significant (p < 0.001) reduction in the usage of anti-diabetes medications post-surgery. The limitations of this study are small sample size and limited follow up period of 1 year. CONCLUSIONS Among T2DM patients, metabolic surgery resulted in significant improvement in beta cell function and insulin sensitivity along with reduction in anti-diabetes medication. Diabetes remission was mainly seen in those who had duration of diabetes <8.5 years.

Abstract
Dumping syndrome is a common but underdiagnosed complication of gastric and oesophageal surgery. We initiated a Delphi consensus process with international multidisciplinary experts. We defined the scope, proposed statements and searched electronic databases to survey the literature. Eighteen experts participated in the literature summary and voting process evaluating 62 statements. We evaluated the quality of evidence using grading of recommendations assessment, development and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 33 of 62 statements, including the definition and symptom profile of dumping syndrome and its effect on quality of life. The panel agreed on the pathophysiological relevance of rapid passage of nutrients to the small bowel, on the role of decreased gastric volume capacity and release of glucagon-like peptide 1. Symptom recognition is crucial, and the modified oral glucose tolerance test, but not gastric emptying testing, is useful for diagnosis. An increase in haematocrit >3% or in pulse rate >10 bpm 30 min after the start of the glucose intake are diagnostic of early dumping syndrome, and a nadir hypoglycaemia level <50 mg/dl is diagnostic of late dumping syndrome. Dietary adjustment is the agreed first treatment step; acarbose is effective for late dumping syndrome symptoms and somatostatin analogues are preferred for patients who do not respond to diet adjustments and acarbose.

Abstract
BACKGROUND AND AIMS Roux-en-Y gastric bypass (RYGB) is refractory to lifestyle and pharmacotherapy measures, requiring reversal of the patient's bariatric surgery. Reversal can lead to weight regain and recrudescence of their comorbidities. Our aim was to report a multicenter experience on the endoscopic management of refractory dumping syndrome with endoscopic transoral outlet reduction (TORe). METHODS A multicenter international series of consecutive patients who underwent TORe with a full-thickness endoscopic suturing device was analyzed for technical success, improvement in Sigstad scores, and weight trajectories after the procedure. Failure was defined as needing an enteral feeding tube, surgical reversal, or repeat TORe. RESULTS One hundred fifteen patients across 2 large academic centers in Germany and the United States underwent TORe for dumping syndrome. Patient age was mean 8.9 ± 1.1 years from their initial RYGB with an average percent total body weight loss of 31% ± 10.6% at the time of endoscopy. Three months postprocedure, the Sigstad score improved from a mean of 17 ± 6.1 to 2.6 ± 1.9 (paired t test P = .0001) with only 2% of patients (n = 2) experiencing weight gain. Mean weight loss and percentage of total body weight loss 3 months post-TORe were 9.47 ± 3.6 kg and 9.47% ± 2.5%, respectively. Six patients (5%) failed initial endoscopic therapy, with 50% (n = 3) successfully treated with a repeat TORe. Three patients underwent surgical reversal, indicating an overall 97% endoscopic success rate. CONCLUSIONS TORe as an adjunct to lifestyle and pharmacologic therapy for refractory dumping syndrome is safe and effective at improving dumping syndrome and reducing rates of surgical revision.

Abstract
BACKGROUND Dumping syndrome is a well-known side effect of laparoscopic gastric bypass (LRYGB), and it is commonly believed that dumping syndrome is less likely to occur after laparoscopic sleeve gastrectomy (LSG), due to the preservation of the pyloric sphincter. However, it is not uncommon for patients undergoing LSG at our center to report symptoms suggestive of dumping syndrome. OBJECTIVE To assess the prevalence of symptoms of dumping syndrome after LSG compared with LRYGB. SETTING A single surgical group at a high-volume (700 cases per year) Bariatric and Metabolic Surgery Center of Excellence. METHODS One thousand four hundred seventy-one LRYGB (366) and LSG (1105) patients received a questionnaire to assess symptoms of dumping syndrome, utilizing a modified version of the Sigstad scoring system. Dumping syndrome was considered to be present when the questionnaire score exceeded a threshold value. RESULTS A total of 360 responses were received (249 LSG, 111 LRYGB). 26.5% (66) LSG and 41.4% (46) LRYGB exceeded the threshold for dumping syndrome (p < 0.01). 84.8% (56) LSG and 84.7% (39) LRYGB reported early dumping syndrome (p > 0.05). Thirty-six percent (24) LSG and 28% (13) LRYGB reported late dumping syndrome (p > 0.05). Twenty-seven percent (62) LSG and 44.4% (44) LRYGB reported at least one symptom of dumping syndrome with sweets (p < 0.05). 34.3% (85) LSG and 35.5% (39) LRYGB reported symptoms when drinking with or within 30 min of a meal (p > 0.05). 14.5% (36) LSG and 17.3% (19) LRYGB reported symptoms after alcohol consumption (p > 0.05). CONCLUSION Dumping syndrome after LSG is prevalent but has not been widely reported. This finding may impact clinicians and patients in their choice of procedure and has relevance in post-operative education and care.

Abstract
Bariatric surgery is increasingly being utilized to manage obesity and obesity related comorbidities, but may lead to the development of micronutrient deficiencies postoperatively. The anatomical, physiological, nutritional and behavioral reasons for micronutrient vulnerabilities are reviewed, along with recommendations for routine monitoring and replacement following surgery. The role the dietitian and their contribution in the postoperative identification, prevention and management of micronutrient vulnerabilities in bariatric patients is described. Specific considerations such as the nutritional and dietetic management of pregnant and lactating women post-bariatric surgery is also discussed.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy with duodenojejunal bypass (LSG-DJB), which has been positioned as a novel bariatric procedure, is the combination of vertical sleeve gastrectomy and proximal intestinal bypass and is theoretically expected to have strong anti-diabetic effect. Also, preserving the pylorus, a physiological valve, leads to less occurrence of dumping syndrome and anastomotic stenosis which are often problematic after laparoscopic Roux-en-Y gastric bypass (LRYGB), a gold standard. The purpose of this study was to investigate the clinical effects of LSG-DJB on obese patients with type 2 diabetes mellitus (T2DM). METHODS Consecutive 75 obese patients (female 44/male 31) associated with T2DM who underwent LSG-DJB and were followed up for at least 1 year were analyzed. The mean age was 45.5 ± 8.6 years, and the mean preoperative body weight (BW) and body mass index (BMI) were 108.4 ± 21.4 kg and 39.6 ± 7.3 kg/m(2), respectively. The mean hemoglobin A1c (HbA1c) at the first visit was 9.0 ± 1.9 %, and the duration of T2DM from diagnosis was 7.2 ± 6.2 years. Thirty-six out of the 75 patients (48 %) were treated with insulin preoperatively. All patients were evaluated and managed under a strict multidisciplinary team approach. The follow-up rate at 1 year was 89 %. RESULTS At 1 year, the mean BW and BMI significantly dropped to 74.6 ± 16.9 kg and 27.5 ± 5.7 kg/m(2), respectively. The mean percent of excess weight loss (%EWL) and percent of total body weight loss (%TWL) were 99.4 ± 42.4 and 31.6 ± 8.8 %, respectively. Consequently, 68.7 % of the patients achieved HbA1c less than 6 %, and 82.1 % of them achieved HbA1c less than 6.5 % without diabetes medications. Glycemic control of HbA1c less than 7 % was achieved in 91.0 % of the patients. The percentage of patients who satisfied the American Diabetes Association (ADA)-defined composite endpoints for cardiovascular disease (CVD) risk factor control increased from 0 % (at baseline) to 31 % (at 1 year). A meal tolerance test revealed significant reduction of glucose area under the curve (AUC) and increase of insulin AUC postoperatively. CONCLUSIONS LSG-DJB for obese patients with T2DM has strong anti-diabetic effect in the short-term; however, a larger number of patients with a longer follow-up period are needed for definitive conclusions.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy with duodenojejunal bypass (LSG-DJB) has been designated as a novel bariatric surgery procedure. This combination of sleeve gastrectomy and proximal intestinal bypass theoretically offers an effective and prolonged anti-diabetes effect. This is a follow-up of our institution's previous report on the short-term effects of LSG-DJB on type 2 diabetes mellitus (T2DM), which a 68.7 % remission (HbA1c <6 % without diabetes medication) rate 1 year after surgery. The aforementioned result was comparable to the reported remission rates of laparoscopic Roux-en-Y gastric bypass. However, the durability of remission remains unknown. OBJECTIVE The objective of this study is to investigate the medium-term (up to 5 years) effects of LSG-DJB on weight loss and T2DM. METHODS In this analysis, consecutive 120 patients (female to male ratio = 61:59, mean age = 44.8 years) with T2DM who underwent LSG-DJB from April 2007 to November 2013 and were followed up beyond 1 year were included. The preoperative mean body weight and BMI were 105.7 kg and 38.5 kg/m2, respectively. The mean HbA1c and fasting blood glucose values were 8.9 % and 194 mg/dL, respectively. The mean duration of T2DM was 7.3 years. Fifty-five patients (46 %) were being treated with insulin prior to surgery. RESULTS The follow-up rate was 97.5 % at 1 year, 73.3 % at 3 years, and 50.0 % at 5 years. The mean body weight was 74.9 kg at 1 year, 76.8 kg at 3 years, and 72.8 kg at 5 years (p < 0.001, compared to the baseline). The mean percent of total body weight loss (%TWL) was 28.9, 28.6, and 30.7 % at 1, 3, and 5 years, respectively. Remission of T2DM was achieved at 63.6, 55.3, and 63.6 % at 1, 3, and 5 years, respectively. Among those who achieved diabetes remission at 1 year, 10.8 % of them experienced recurrence during the subsequent follow-up period. CONCLUSION Although recurrence of T2DM is observed in some patients over time, LSG-DJB is an effective procedure for achieving significant weight loss and improvement of glycemic control, and the effects seem to be durable up to 5 years.

Abstract
BACKGROUND Having accurate information on bariatric surgery-related gastrointestinal (GI) symptoms is critical for patient care. OBJECTIVE To report on surgery-related GI symptoms over the first 3 years following Roux-en-Y gastric bypass and laparoscopic adjustable gastric band. SETTING Three academic medical centers in the United States. METHODS As a substudy of the Longitudinal Assessment of Bariatric Surgery Consortium, 183 participants (pre-surgery median body mass index = 45.1 kg/m2; median age = 46 yr; 83.1% female). completed the Eating Disorder Examination-Bariatric Surgery Version interview at≥1 annual assessment. Patients self-reported frequency of dysphagia, dumping syndrome, and spontaneous vomiting. RESULTS Prevalence of dysphagia at least once weekly decreased post-laparoscopic adjustable gastric band surgery from 43.9% (95% confidence interval [CI], 32.2-55.6) in year 1 to 27.5% (95% CI, 15.2-39.9) in year 3 (P = .02). Dysphagia and dumping at least once weekly also appeared to decrease in years 1-3 post-Roux-en-Y gastric bypass (i.e., from 16.7% [95% CI, 9.4-24.1] to 10.9% [95% CI, 4.0-17.8] and from 9.9% [95% CI, 4.3-15.5] to 6.3% [95% CI, 1.7-10.9], respectively), but power was limited to evaluate trends. Vomiting at least once weekly was rare (<6%) in years 1-3 following both procedures. Controlling for potential confounders and surgical procedure, loss of control eating at least once weekly was associated with higher risk of at least once weekly dysphagia (relative risk = 2.01, 95% CI, 1.36-2.99, P = .001). CONCLUSIONS The prevalence of bariatric surgery-related GI symptoms appears to decrease across follow-up. Symptoms were associated with loss of control eating, suggesting a target for clinical intervention.

Abstract
Adolescent obesity has markedly increased worldwide in both its extent and prevalence in recent decades and obesity prevention strategies are failing. As a result, effective treatment strategies are urgently needed. As behavioral and pharmacological treatment approaches have only moderate effects in severe obesity, bariatric surgery has begun to emerge as a treatment option. In this debate article, we offer arguments opposing and supporting bariatric surgery in the treatment of severe obesity in adolescents. Bariatric surgery has superior therapeutic outcomes with respect to weight loss and resolution of comorbid diseases over other existing treatments. However, long-term outcomes after bariatric surgery in adolescents are only just beginning to emerge. Furthermore, the procedures are generally considered irreversible, apart from gastric banding. Most importantly, not all adolescents seem to benefit greatly from bariatric surgery and we are not yet able to reliably identify those who stand to gain the greatest benefit. The authors agree that adolescent bariatric surgery should be offered exclusively within formal adolescent obesity programs, delivered by specialist multidisciplinary child/adolescent obesity teams, and within specialist centers, in order to optimize outcomes and minimize potential detrimental effects. Patients and their family/carers must be educated regarding the benefits and risks, potential side effects, expected changes in eating behavior and the lifelong requirement for regular medical follow-up after surgery. Before embarking upon a surgical treatment pathway in adolescents with severe obesity, it may also be beneficial to ensure compliance to treatment is demonstrated, in order to minimize the risk of nutritional deficiencies and associated potential complications.

Abstract
BACKGROUND Dumping syndrome after Roux-en-Y gastric bypass (RYGB) is traditionally associated with the consumption of refined carbohydrates, but the role of dietary fat is unclear. OBJECTIVES This study compares symptoms after consumption of a carbohydrate-rich or fat-rich beverage to determine perceived symptoms, glycemic control, and pulse rate. SETTING University hospital. METHODS We assessed perceived symptoms (Sigstad's Dumping Index) and glycemic control (P-glucose and S-insulin) as well as autonomic nervous system activity (reflected by arterial pulse rate) after a standardized liquid meal test (440 kcal/300 mL carbohydrates [CARB] or fat [FAT]) in a randomized crossover blinded setting. Blood samples were drawn before and 1, 15, 30, and 60 minutes after finishing each meal and the area under the curve (AUC) was calculated. RESULTS Twelve patients 42±10 months after undergoing RYGB were studied. AUC differed between drinks for glucose (P = .003) and insulin (P = .005). Pulse rate increased more after CARB than after FAT (P = .01). AUC for perceived symptoms in the Sigstad's Dumping Index were similar after meals (P = .79), yet the pattern of type of symptoms differed. CONCLUSION In patients with RYGB, a meal with predominant fat content resulted in as much perceived dumping symptoms as a carbohydrate-profiled meal. As expected, an increase in glucose and insulin levels were found only after carbohydrate intake and the pulse rise was more pronounced for carbohydrates than fat. Dietary counseling in patients undergoing RYGB should address dietary fat as well as traditional information about carbohydrates to avoid dumping 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 Roux-en-Y gastric bypass (RYGB) results in pronounced weight loss in morbidly obese patients but may also cause adverse effects like early dumping and hypoglycemia. Prevalence data on these complications and their potential predictors are sparse. OBJECTIVE To assess the prevalence and possible predictors of early dumping and hypoglycemia in a population-based cohort of RYGB patients. SETTING University Hospital, Denmark. DESIGN A questionnaire survey was performed in the Central Denmark Region including RYGB-operated patients (years 2006-2011, n = 2238) and a nonoperated comparison cohort (n = 89). The Dumping Rating Scale and the Edinburgh Hypoglycemia Scoring System, together with demographic and clinical characteristics, were used, and possible predictors were examined by logistic regression. RESULTS The response rate was 64% (1429/2238). In total, 9.4% (134/1429) and 6.6% (95/1429) experienced moderate or severe symptoms of early dumping and hypoglycemia, respectively, which were significantly higher than in the comparison cohort. Because 3.4% (95% CI: 2.5-4.4) of the RYGB group experienced both early dumping and hypoglycemia, the total prevalence of 1 or both conditions was 12.6 (95% CI 10.9-14.4). Possible predictors for both conditions were body mass index (BMI)<25 kg/m2 (odds ratio [OR] 1.70 (95% CI: 0.98-2.95) and OR 1.60 (95% CI: .83-3.06), respectively) compared with patients with BMI 25-30 kg/m2. Younger age seemed to increase the risk of both conditions (<35 yr: OR 1.75 (95% CI: 1.11-2.75) and OR .59 (95% CI: .93-2.72), respectively) compared with patients>45 years. CONCLUSION Symptoms of early dumping and hypoglycemia were rather common with a prevalence of 1 or both conditions of 12.6% after RYGB. Predictors included younger age and a lower BMI.

Abstract
BACKGROUND The aim was to determine the effects of fat and protein preloads on pouch emptying (PE), caecal arrival time (CAT), glucose absorption, blood glucose (BSL), gut hormones, haemodynamics and gastrointestinal (GI) symptoms in subjects who had undergone Roux-en-Y gastric bypass (RYGB) >12 months previously. METHODS Ten RYGB subjects were studied on three occasions, in randomised order, receiving 200-ml preloads of either water, fat (30 ml olive oil) or whey protein (55 g), 30 min before a mixed meal. PE, CAT, BSL, plasma 3-O-methyl-D-glucopyranose (3-OMG), insulin, glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide 1 (GLP-1) and glucagon, blood pressure (BP), heart rate (HR) and GI symptoms were assessed over 270 min. RESULTS Although fat and protein preloads did not alter PE of either solids or liquids, the CAT of solids, but not liquids, was longer than that after the water preload (fat 68 ± 5 min and protein 71 ± 6 min vs. water 46 ± 5 min; P = 0.02). BSL elevated promptly after the meal on all days (P < 0.001), but after protein, the magnitude and integrated increases in the first 75 min were less than fat and water preloads (area under the curve (AUC(0-75 min)), 18.7 ± 18.2 vs. 107.2 ± 30.4 and 76.1 ± 19.3 mmol/L/min; P < 0.05). Compared to water preload, the protein and fat preloads were associated with greater increases in plasma insulin, GLP-1 and glucagon concentrations, a reduction in BP, and greater increases in HR, fullness, bloating and nausea. Plasma 3-OMG levels were lower after the protein than after the water and fat preloads (P < 0.001). CONCLUSIONS Given its effects to attenuate post-prandial glycaemia, reduce intestinal glucose absorption and potentiate the "incretin response", without inducing more adverse post-prandial GI symptom, protein preload may prove clinically useful in RYGB patients and warrant further evaluation, particularly in those with type 2 diabetes (T2DM) and/or dumping syndrome.

Abstract
Objectives. This study aimed to explore the expression of GLP-1 receptor in hypothalamus and gastrointestinal tissues after Roux-en-Y gastric bypass (RYGB) surgery in diabetic rats. Methods. Male 12-week-old Wistar rats (control) and Goto-Kakizaki rats (diabetic) were randomly divided into two groups, respectively: control sham surgery group (C), control RYGB group (C + R), diabetic sham surgery group (D), and diabetic RYGB group (D + R). Body weight and blood glucose were monitored before and after surgery every week. Eight weeks after surgery, all rats were sacrificed and the serum fasting GLP-1 concentrations were measured by ELISA. GLP-1R and DPP-4 expression in hypothalamus and ileum were measured by RT-PCR. Results. The body weight and fasting/random blood glucose in the D + R group decreased significantly compared with the D group (P < 0.05). Serum GLP-1 levels in diabetic rats treated with RYGB were higher than the corresponding sham surgery rats. The expression of GLP-1R of hypothalamus in RYGB-treated diabetic rats was significantly higher than those of the sham surgery diabetic rats and both control group rats (P < 0.05). We found a negative correlation between hypothalamus GLP-1R mRNA and blood glucose level. No significant difference was seen in ileum GLP-1R and DPP-4 expression among all groups. Conclusions. RYGB efficiently promoted serum GLP-1 levels and the expression of GLP-1 receptor in the hypothalamus in diabetic rats. These data suggest that the hypothalamus GLP-1R may play an important role in the GLP-1 system for improving glucose homeostasis after reconstruction of the gastrointestinal tract.

Abstract
Gastric surgery has long been known to be a cause of dumping syndrome (DS). However, the increasing incidence of gastric bypass surgery, as well as reports of DS unrelated to previous gastric surgeries, has increased the importance of understanding DS in recent years. DS is due to the gastrointestinal response to voluminous and hyperosmolar chyme that is rapidly expelled from the stomach into the small intestine. This response involves neural and hormonal mechanisms. This review encompasses the symptoms, diagnosis, and treatment approaches of DS and also focuses on the current research status of the pathophysiology of DS.

Abstract
BACKGROUND The optimal operative technique in gastric bypass (RYGB) is still under debate. We have studied patient-reported gastrointestinal symptoms and weight loss 5 years after RYGB performed with three different stapling techniques for the gastrojejunal anastomosis (GJ). METHODS Out of 593 patients operated with RYGB, 489 patients [80.2% women, body mass index (BMI) 44.9 (33-68) kg/m(2)] answered our 5-year follow-up questionnaire concerning gastrointestinal symptoms (vomiting, reflux, dumping, abdominal pain or diarrhea), weight loss, need for postoperative endoscopic interventions and overall satisfaction with the procedure. We compared the results for three different GJ techniques: linear stapler (LS, n = 103), 21-mm circular stapler (C21, n = 88) and 25-mm circular stapler (C25, n = 298). RESULTS Dumping was the most commonly reported symptom (14.1% of all patients on a weekly to daily basis), however, less frequently reported in the C25 group (p < 0.05). Vomiting, prevalent in 2.9% of all patients, was more frequently reported in the C21 group (p < 0.01). No group consistently showed greater weight loss compared to the other two groups. A higher incidence of endoscopic dilatations due to strictures was reported in the C21 group (12.5% compared to 4.5% of all patients, p < 0.05). Overall patient satisfaction was high (88%). CONCLUSION Our data suggest that the technique for the construction of the GJ in RYGB affects gastrointestinal symptoms 5 years postoperatively. The difference is moderate but indicates that a narrow GJ results in increased frequency of vomiting and need for endoscopic interventions without improving the weight result.

Abstract
BACKGROUND Dumping syndrome is a common complication after surgery of the upper gastrointestinal tract with symptoms ranging from mild gastrointestinal discomfort and moderate vasomotor disturbances, to severe hyperinsulinemic hypoglycemia. Due to the increasing number of bariatric procedures being performed worldwide, bariatric surgery has become the most common cause for this disease entity. OBJECTIVE The aim of this review is to highlight the evidence for the physiological mechanisms contributing to dumping syndrome after the two most common bariatric surgery procedures, Roux-en-Y gastric bypass and sleeve gastrectomy, to discuss technical aspects of the procedures underlying the development of the syndrome, patient-related predictive factors and other differential diagnoses, together with diagnostic and therapeutic algorithms.

Abstract
Bariatric surgery leads to significant long-term weight loss, particularly Roux-en-Y gastric bypass (RYGB). The mechanisms underlying weight loss have not been fully uncovered. The aim of this review is to explore the changes in food preferences, as a novel mechanism contributing to weight loss, and also focus on the underlying processes modulating eating behaviour after bariatric surgery. Patients after gastric bypass are less hungry and prefer healthier food options. They develop an increased acuity to sweet taste, which is perceived as more intense. The appeal of sweet fatty food decreases, with functional MRI studies showing a corresponding reduction in activation of the brain reward centres to high-energy food cues. Patients experiencing post-ingestive symptoms with sweet and fatty food develop conditioned aversive behaviours towards the triggers. Gut hormones are elevated in RYGB and have the potential to influence the taste system and food hedonics. Current evidence supports a beneficial switch in food preferences after RYGB. Changes within the sensory and reward domain of taste and the development of post-ingestive symptoms appear to be implicated. Gut hormones may be the mediators of these alterations and therefore exploiting this property might prove beneficial for designing future obesity treatment.

Abstract
BACKGROUND Dumping syndrome is the term used to describe a common set of symptoms following gastric surgery, and is characterised by postprandial discomfort which can entail nutritional problems. The condition was well known when surgery was the usual treatment for peptic ulcer disease. The increasing number of operations for morbid obesity means that the condition is once again of relevance, and health personnel will encounter these patients in different contexts. This article discusses the prevalence, symptomatology and treatment of dumping syndrome. MATERIAL AND METHOD This review article is based on a selection of articles identified in PubMed and assessed as having particular relevance for elucidating this issue, as well as on the authors' own clinical experience. RESULTS Early dumping syndrome generally occurs within 15 minutes of ingesting a meal and is attributable to the rapid transit of food into the small intestine. Nausea, abdominal pain, diarrhoea, a sensation of heat, dizziness, reduced blood pressure and palpitations are typical symptoms. Lethargy and sleepiness after meals are common. Late dumping syndrome occurs later and may be attributed to hypoglycaemia with tremors, cold sweats, difficulty in concentrating, and loss of consciousness. Dumping-related symptoms occur in between 20 and 50% of patients following gastric surgery. Early dumping syndrome is more frequent than late dumping syndrome. It is estimated that 10-20% of patients have pronounced symptoms and 1-5% have severe symptoms. The diagnosis is usually made on the basis of typical symptoms. Most patients experience alleviation of the symptoms over time and with changes in diet and eating habits. Further patient evaluation and drug or surgical intervention may be relevant for some individuals. INTERPRETATION Dumping-related symptoms are common after gastric surgery. The extent of obesity surgery in particular means that health personnel should be familiar with this condition.

Abstract
BACKGROUND Data on gastrointestinal (GI) side effects of bariatric surgery are limited because of incomplete reporting, cross-sectional samples, and nonstandardized assessments. OBJECTIVE To report on GI side effects over the first 6 months after Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB). SETTING Academic medical center, United States. METHODS One hundred forty-four patients completed a standardized clinical interview 6 months after operation, including questions on the occurrence and frequency of episodes of dumping syndrome, vomiting, and plugging for each of the past 6 months; monthly rates were stable, so results were averaged over the entire period. Although data were collected as part of a randomized controlled trial, randomization group and the interaction of group by surgical procedure were not related to GI side effects. Thus, results are reported by procedure only (RYGB, n = 87; LAGB, n = 56). RESULTS RYGB patients had a higher preoperative body mass index (BMI) than LAGB patients (46.8±6.8 versus 43.5±4.8 kg/m(2), respectively; P = .001), were more likely to report dumping (45.7% versus 4.7%, P<.0001), and were less likely to report plugging (45.7% versus 79.1%, P = .0005). Vomiting did not differ significantly by procedure (68.6% versus 65.1%, P = .7). Most patients experienced each GI side effect less than once per week. CONCLUSION Although self-reported GI side effects were common over the first 6 months after operation, the frequency of episodes was relatively low. Longer-term follow-up is needed to determine whether symptoms worsen or improve over time.

Abstract
Background Bariatric operations mostly combine a restrictive gastric component with a rerouting of the intestinal passage. The pylorus can thereby be alternatively preserved or excluded. With the aim of performing a “pylorus-preserving gastric bypass”, we present early results of a proximal postpyloric loop duodeno-jejunostomy associated with a sleeve gastrectomy (LSG) compared to results of a parallel, but distal LSG with a loop duodeno-ileostomy as a two-step procedure. Methods 16 patients underwent either a two-step LSG with a distal loop duodeno-ileostomy (DIOS) as revisional bariatric surgery or a combined single step operation with a proximal duodeno-jejunostomy (DJOS). Total small intestinal length was determined to account for inter-individual differences. Results Mean operative time for the second-step of the DIOS operation was 121 min and 147 min for the combined DJOS operation. The overall intestinal length was 750.8 cm (range 600-900 cm) with a bypassed limb length of 235.7 cm in DJOS patients. The mean length of the common channel in DIOS patients measured 245.6 cm. Overall excess weight loss (%EWL) of the two-step DIOS procedure came to 38.31% and 49.60%, DJOS patients experienced an %EWL of 19.75% and 46.53% at 1 and 6 months, resp. No complication related to the duodeno-enterostomy occurred. Conclusions Loop duodeno-enterosomies with sleeve gastrectomy can be safely performed and may open new alternatives in bariatric surgery with the possibility for inter-individual adaptation.

Abstract
There is a lack of prevalent data for dumping syndrome (DS) and methods discriminating between different symptoms of the DS. A self-assessment questionnaire, the Dumping Symptom Rating Scale (DSRS), was developed. The aim was to measure the severity and frequency of nine dumping symptoms and to evaluate the construct validity of the DSRS. Pre- and 1 and 2 years after Roux-en-Y gastric bypass surgery, 47 adults and 82 adolescents completed the DSRS. Cognitive interview was performed. Reliability and construct validity were tested. Effect sizes (ES) of changes were calculated. Patients found the questionnaire relevant. A high proportion of the respondents reported no symptoms affecting them negatively at all (floor effects). However, 12 % stated, quite severe, severe, or very severe problems regarding fatigue after meal and half of them were so tired that they needed to lie down. Nearly 7 % reported quite severe, severe, or very severe problems dominated by nausea and 6 % dominated by fainting esteem. The internal consistency reliability was adequate for both severity (0.81-0.86) and frequency (0.76-0.84) scales. ES were small, since some subjects experienced symptoms already preoperatively. Although most patients reported no or mild dumping symptoms 1 and 2 years after gastric bypass surgery, around 12 % had persistent symptoms, in particular, postprandial fatigue, and needed to lie down. Another 7 % had problems with nausea and 6 % had problems with fainting esteem. The DSRS is a reliable screening tool to identify these patients.

Abstract
The clinical efficacy of bariatric surgery has encouraged the scientific investigation of the gut as a major endocrine organ. Manipulation of gastrointestinal anatomy through surgery has been shown to profoundly affect the physiological and metabolic processes that control body weight and glycaemia. The most popular bariatric surgical procedures are gastric bypass, adjustable gastric banding and vertical sleeve gastrectomy. Even though these procedures were designed with the aim of causing restriction of food intake and nutrient malabsorption, evidence suggests that their contributions to weight loss are minimal. Instead, these interventions reduce body weight by decreasing hunger, increasing satiation during a meal, changing food preferences and energy expenditure. In this Review, we have explored these mechanisms as well as their mediators. The hope is that that their in-depth investigation will enable the optimization and individualization of surgical techniques, the development of equally effective but safer nonsurgical weight-loss interventions, and even the understanding of the pathophysiology of obesity itself.

Abstract
Bariatric surgery has been demonstrated to be an effective treatment for patients with severe obesity, producing improvements in many comorbid conditions, including type 2 diabetes, hypertension, obstructive sleep apnea, and dyslipidemia. The loss of body weight and resolution of comorbidities have been more recently found to be the result of functional and metabolic changes produced by the surgical procedures. Nonetheless, bariatric surgery is still considered to be a tool that is supported by health behaviors characteristic of all weight loss programs—that is, adoption of healthy eating patterns, engagement in robust physical activity, and implementation of constructive coping strategies. In addition, patients who undergo bariatric surgery face challenges that are particular to this population, including adjustment to rapid and significant reduction in body weight, forced alterations in eating behavior, and risk of alcohol misuse. This state-of-the-art review focuses on the research and resultant recommendations regarding lifestyle management for patients who have undergone bariatric surgery.

Abstract
Due to the rapidly expanding prevalence of obesity, bariatric surgery is becoming an increasingly popular treatment option. Bariatric surgeries including Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) produce long-term weight loss and metabolic improvement, reducing mortality. This review discusses the important benefits and risks of RYGB and VSG, highlighting hypothesized mechanisms for these effects. We present data suggesting that VSG, albeit a newer procedure, may be as effective as RYGB with fewer adverse effects including less surgical risk, reduced nutritional deficiency, and less incidence of dumping syndrome. This may position VSG as an increasingly important procedure, particularly for the treatment of pediatric obesity.

Abstract
Despite considerable scientific progress on the biological systems that regulate energy balance, we have made precious little headway in providing new treatments to curb the obesity epidemic. Diet and exercise are the most popular treatment options for obesity, but rarely are they sufficient to produce long-term weight loss. Bariatric surgery, on the other hand, results in dramatic, sustained weight loss and for this reason has gained increasing popularity as a treatment modality for obesity. At least some surgical approaches also reduce obesity-related comorbidities including type 2 diabetes and hyperlipidemia. This success puts a premium on understanding how these surgeries exert their effects. This review focuses on the growing human and animal model literature addressing the underlying mechanisms. We compare three common procedures: Roux-en-Y Gastric Bypass (RYGB), vertical sleeve gastrectomy (VSG), and adjustable gastric banding (AGB). Although many would group together VSG and AGB as restrictive procedures of the stomach, VSG is more like RYGB than AGB in its effects on a host of endpoints including intake, food choice, glucose regulation, lipids and gut hormone secretion. Our strong belief is that to advance our understanding of these procedures, it is necessary to group bariatric procedures not on the basis of surgical similarity but rather on how they affect key physiological variables. This will allow for greater mechanistic insight into how bariatric surgery works, making it possible to help patients better choose the best possible procedure and to develop new therapeutic strategies that can help a larger portion of the obese population.

Abstract
Over the past 20 years bariatric surgery proved to be a valid treatment for reduction and elimination of obesity-related diseases and long-term sustainable weight loss. Minimally invasive or laparoscopic techniques such as laparoscopic Roux-en-Y (LRNY) have replaced open procedures. Many factors play important roles in the small intricacies and variations of the procedure, chief of which is the creation and size of the gastrojejunostomy. Regardless of the variations in technique, the LRNY remains the gold standard for the surgical treatment of clinically severe or morbid obesity, with relatively low morbidity and mortality.

Abstract
AIM To investigate the therapeutic effects of different styles of gastric bypass surgery on type 2 diabetes mellitus (T2DM) GK rats. METHODS Twenty 6-8-week-old male GK rats were randomly divided into four groups: group A was operated by Roux-en-Y gastrojejunostomy with duodenum exclusion and stomach capacity maintenance, group B was operated by loop-type gastrojejunostomy with duodenum exclusion and stomach capacity maintenance, group C was operated by Roux-en-Y gastrojejunostomy with partial gastrectomy, and group D was operated by loop-type gastrojejunostomy with partial gastrectomy. Changes of fasting blood glucose, oral glucose tolerance test (OGTT), and insulin tolerance test (ITT) in different operations were detected. RESULTS The operations exerted good effects on controlling blood glucose in groups A, B, C, and D. There was no significant difference between groups A and C (P > 0.05) or between groups B and D (P > 0.05), while operations in groups A and C were more effective than groups B and D (P < 0.05). On the 21st day after surgery, OGTT in animals of groups A and C was significantly improved, as indicated by a 34% reduction in the area under the curve (AUC) for blood glucose (P < 0.05 versus groups B and D); pregavage insulin levels (ng/ml) were significantly decreased in groups A and C (P < 0.05 versus groups B and D). The insulin tolerance test (ITT) confirmed impaired insulin sensitivity in groups B and D, compared with groups A and C. CONCLUSIONS Gastric bypass surgery might be effective to treat type 2 diabetes mellitus (T2DM), and Roux-en-Y gastrojejunostomy might be more effective than other operative styles.

Abstract
BACKGROUND Cyclic vomiting syndrome (CVS) in adults is a disorder characterized by recurrent and stereotypic episodes of severe nausea and vomiting separated by symptom-free periods. Autonomic dysfunction has been a postulated mechanism for the pathogenesis of this disorder in children but has not been explored in adults. METHODS Our goals were to investigate autonomic nerve function in adult patients with CVS. The sympathetic nervous system was evaluated through postural changes in heart rate and blood pressure and sympathetic skin response in the hand and foot. The parasympathetic nervous system was tested through heart rate response to deep breathing [expiration/inspiration (E/I)], Valsalva and postural indices (30 : 15 ratio). All patients had a 4-h standard isotope labeled egg beater meal gastric emptying test (GET). KEY RESULTS Twenty-two adult (18 female), mean age 35 ± 11 (range 19-61 years), who met Rome III criteria for CVS were included. History of migraine headache was reported in three patients. Five (23%) had pediatric onset. Of 21 patients who completed the test, nine patients had 21 abnormalities detected in their autonomic nerve testing profile and the remaining 12 had normal autonomic function results. Orthostatic tachycardia was observed in two (mean heart rate increase 39 beats min(-1)) and a decline in blood pressure (BP) in three patients (mean BP drop 30/14 mmHg). Parasympathetic abnormalities were elicited in six patients with an abnormal response to deep breathing and E/I index <1.25. Sympathetic nerve dysfunction was reported in seven patients with absent sympathetic skin response in the foot and/or hand. Twelve (57%) of CVS group had rapid GET (<50% retention at 1 h). The frequency of abnormal autonomic nerve function was not significantly higher in rapid GET subgroup. CONCLUSIONS & INFERENCES (i) Autonomic nerve dysfunction is common in adult CVS patients, being observed in 43% of our cohort; (ii) Sympathetic abnormalities dominate; and (iii) Rapid gastric emptying, present in 57% of patients, did not correlate with autonomic testing results. These new data provide more insight into the pathophysiology of CVS in adults and help explain the spectrum of clinical manifestations observed in this entity.

Abstract
OBJECTIVE We sought to provide guidelines for the nutritional and endocrine management of adults after bariatric surgery, including those with diabetes mellitus. The focus is on the immediate postoperative period and long-term management to prevent complications, weight regain, and progression of obesity-associated comorbidities. The treatment of specific disorders is only summarized. PARTICIPANTS The Task Force was composed of a chair, five additional experts, a methodologist, and a medical writer. It received no corporate funding or remuneration. CONCLUSIONS Bariatric surgery is not a guarantee of successful weight loss and maintenance. Increasingly, patients regain weight, especially those undergoing restrictive surgeries such as laparoscopic banding rather than malabsorptive surgeries such as Roux-en-Y bypass. Active nutritional patient education and clinical management to prevent and detect nutritional deficiencies are recommended for all patients undergoing bariatric surgery. Management of potential nutritional deficiencies is particularly important for patients undergoing malabsorptive procedures, and strategies should be employed to compensate for food intolerance in patients who have had a malabsorptive procedure to reduce the risk for clinically important nutritional deficiencies. To enhance the transition to life after bariatric surgery and to prevent weight regain and nutritional complications, all patients should receive care from a multidisciplinary team including an experienced primary care physician, endocrinologist, or gastroenterologist and consider enrolling postoperatively in a comprehensive program for nutrition and lifestyle management. Future research should address the effectiveness of intensive postoperative nutritional and endocrine care in reducing morbidity and mortality from obesity-associated chronic diseases.

Abstract
OBJECTIVE The objective of this research was to determine the real prevalence and characteristics of dumping syndrome in a series of cases submitted to laparoscopic Roux-en-Y gastric bypass for morbid obesity. METHODS We assessed dumping symptoms in 34 patients who had undergone that procedure; they filled a questionnaire, which included the dumping clinical diagnosis score proposed by Sigstad. RESULTS regarding patients' complaints, dumping prevalence was 44%. This number increased to 76% when applying the Sigstad's score. The most frequent symptoms were 'need for lying down' (88%), fatigue (69%) and sleepiness (69%). Only 28% of the dumpers felt incapable of performing everyday activities. There was no difference in weight loss percentage between dumpers and non-dumpers. CONCLUSION The Sigstad score is an usefull tool for the diagnostic of dumping, but a critic vision must be adopted when using in patients submitted to the Roux en Y gastric bypass. The dumping syndrome was frequent in this group, although usually under-diagnosed; it neither hampers patients' everyday activities considerably, nor helps in the weight-loosing process.

Abstract
Between 1998 and 2004, the total number of bariatric procedures increased almost 10-fold, from 13,386 procedures in 1998 to 121,055 in 2004. Current estimates suggest the number of bariatric operations will exceed 220,000 in 2010. Bariatric surgery encompasses several surgical techniques classified as restrictive or malabsorptive, based on the main mechanism of weight loss. Clinical studies and meta-analyses show that bariatric surgery decreases morbidity and mortality when compared with nonsurgical treatments. A successful long-term outcome of bariatric surgery is dependent on the patient's commitment to a lifetime of dietary and lifestyle changes. The registered dietitian (RD) is an important member of the bariatric team and provides critical instructions to help patients adhere to the dietary changes consistent with surgery. Referencing current literature, this article outlines the indications, contraindications, and types of bariatric surgery. The role of the RD for preoperative and postoperative nutrition assessment and medical nutrition therapy is highlighted. Management of long-term nutrition issues is also reviewed. The current recommendations include a multivitamin/mineral supplement plus vitamin B-12, calcium, vitamin D-3, iron, and folic acid. Given the increasing prevalence of obesity and bariatric surgery procedures, caring for patients who have undergone surgery will be an expanding role for the RD. Close postoperative follow-up and careful monitoring will improve the odds for successful surgical outcomes, and RDs play a very important part in this process.

Abstract
AIMS To investigate the current incidence and identify the current etiologies of rapid gastric emptying (dumping syndrome) in patients with a spectrum of gastrointestinal symptoms, including nausea, vomiting, abdominal pain, or diarrhea. METHODS The results for a 4-h radionuclide gastric emptying test (GET) using a standardized scintigraphic technique were reviewed in 545 patients to see which patients met criteria for rapid gastric emptying, defined as >50% emptying of isotope-labeled solid meal at 1 h. RESULTS Forty-eight of 545 (8.8%) patients (28 females, mean age 46 +/- 2 years, range 32-58 years) had rapid GET. Seventeen of 59 (35%) met Rome III diagnostic criteria for cyclic vomiting syndrome (CVS). Twelve of these 59 (25%) patients were regarded as non-ulcer dyspepsia and six (13%) had dyspepsia in the setting of diabetes mellitus. Five (10.5%) were post-fundoplication surgery, where an accidental vagotomy was confirmed by sham meal challenge; previous gastric bypass surgery for obesity had been performed in three (6%) patients. Five (10.5%) patients with unexplained abdominal pain and diarrhea had the working diagnosis of irritable bowel syndrome. CONCLUSIONS Rapid gastric emptying can be identified in a sizeable subset (9%) of patients with unexplained nausea, vomiting, abdominal pain, and diarrhea when criteria are applied to the standardized scintigraphic gastric emptying meal.

Abstract
BACKGROUND Weight loss surgery induces a marked change in eating behavior. However, not much work has been done characterizing the eating behavior after weight loss surgery. We conducted a detailed analysis of patients' eating behavior 18-35 months after Roux-en-Y gastric bypass surgery, determined whether preoperative eating disorders might be associated with non-normative postoperative eating, and examined the association of such eating behaviors with weight loss and psychopathology. METHODS A sample of 59 patients who had undergone Roux-en-Y gastric bypass was interviewed in person after surgery about a range of eating behaviors, including binge eating, chewing and spitting out food, picking at and nibbling food, and nocturnal eating and compensatory behaviors such as vomiting and laxative and diuretic misuse. An established semistructured interview was used. The prevalence of preoperative eating disorders was assessed retrospectively. The eating-related and general psychopathology and quality of life were assessed using self-report questionnaires before and after surgery. RESULTS Subjective bulimic episodes were reported by 25% and vomiting for weight and shape reasons by 12% of the participants, on average, 2 years after surgery. Subjective bulimic episodes were significantly associated with a preoperative binge eating disorder, with more eating-related and general psychopathology after surgery, and with less weight loss. CONCLUSION A substantial subgroup of patients with a preoperative eating disorder will develop binge eating after surgery that might be associated with less weight loss. A subsample will start vomiting for weight and shape reasons after bariatric surgery. Clinicians must probe carefully for these behaviors postoperatively to identify patients in need of treatment of pathological eating behaviors.

Abstract
Weight loss surgery is recommended for adult patients with morbid obesity and has been used on a case by case basis in the pediatric population. Surgery, however,is just a tool added to the two mainstays of therapy for obesity: 1.) controlled dietary intake and 2.) increases inactivity and exercise behaviors. For the pediatric population,the health consequences of obesity are profound with increased cardiovascular risk during adolescence and increased mortality in adulthood. Currently accepted guidelines for weight loss surgery referral use BMI cut points that are the same as for adults: BMI > or = 35 kg/m(2) and serious comorbidities of obesity or BMI > or = 40 kg/m(2) with minor comorbidities of obesity. A multidisciplinary approach to weight management must be utilized, and a lifetime of follow-up must be addressed. The most commonly performed operations for obesity are laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB). LAGB is safer and does not permanently alter gastrointestinal continuity; however, LAGB is not currently approved for implantation in adolescent patients. LRYGB involves a complex, permanent altering of the gastrointestinal anatomy and is associated with more complications around the time of surgery and is not subject to FDA approval because there is no associated implant. In each operation, appetite is suppressed by construction of a virtual (LAGB) or real(LRYGB) pouch. The dynamics and speed of appetite suppression and, consequently, weight loss are typically different for each operation though longer-term outcomes may be similar. Short- and long-term risks of surgery must be carefully weighed against the benefits of the associated weight loss for each patient. The patient must be empowered to understand the importance of lifestyle and behavior in achieving long-term health.
