Abstract
Despite the well-documented safety of laparoscopic RYGB, several short-term and long-term complications, with varying degrees of morbidity and mortality risk, are known to occur. Bariatric surgeons, all too familiar with these complications, should be knowledgeable in risk-reduction strategies to minimize the incidence of complication occurrence and recurrence. Bariatric and nonbariatric surgeons who evaluate and treat abdominal pain should be familiar with these complications to facilitate early recognition and intervention, thereby minimizing the associated morbidity and mortality.

Abstract
BACKGROUND The number of bariatric surgical procedures in Norway is increasing. Patients who undergo bariatric surgery may experience surgical, medical and nutritional complications. Follow-up of these patients is therefore important. METHODS The article is based on non-systematic literature searches in PubMed and on the clinical experience of the authors. RESULTS Bariatric surgery induces significant and sustained weight loss and improves obesity-related disorders. Gastric bypass is the most commonly performed bariatric procedure in Norway. This procedure is associated with a 30-day mortality of below 0.5 %, while severe complications occur in approximately 5 % of patients. Late complications include internal herniation, intestinal ulcers and gallbladder disease. After surgery all patients are given iron, vitamin D/calcium and vitamin B12 supplements to prevent vitamin and mineral deficiencies. Gastrointestinal symptoms and postprandial hypoglycaemia after surgery can be improved by dietary modifications, and the need for anti-diabetic and blood pressure lowering medications is reduced. Dose adjustment of other medications may also be necessary. Pregnancy is not recommended during the first year after bariatric surgery. Many patients need plastic surgery after the operation. INTERPRETATION Complications after bariatric surgery may manifest in the long term. Regular follow-up is required. General practitioners should be responsible for follow-up in the long term, and should be familiar with common and serious complications as well as normal symptomatology after bariatric surgery.

Abstract
BACKGROUND Calcium supplementation is commonly recommended for patients after Roux-en-Y gastric bypass to avert bone loss. To test the hypothesis that effervescent (liquid) potassium-calcium-citrate (PCC) might be more bioavailable than a tablet formulation of calcium citrate (Citracal Petite), the present study compared a single dose response of the 2 compounds. The present study was conducted at the University of Texas Southwestern Medical School at Dallas. METHODS A total of 15 patients who had undergone Roux-en-Y gastric bypass were included in a 2-phase, crossover, randomized study comparing the single-dose bioavailability of PCC versus Citracal Petite. After following a restricted diet for 1 week, the participants ingested either a single dose of 400 mg elemental calcium as PCC or Citracal Petite. Sequential serum and urine samples were collected for a 6-hour period after the dose and analyzed for calcium, parathyroid hormone, and acid-base parameters. RESULTS Compared with citracal petite, PCC significantly increased the serum calcium concentrations at 2, 3, and 4 hours after the oral load. The peak to baseline variation and increment in serum calcium (area under the curve) were significantly greater after PCC (P = .015 and P = .002, respectively). Concurrently, the baseline to nadir variation and decrement in serum parathyroid hormone (area over the curve) were significantly greater after PCC (P = .004 and P = .005, respectively). Moreover, compared with Citracal Petite, PCC caused a significantly greater increment in urinary citrate (P < .0001) and potassium (P = .0004) and a significantly lower increase in urinary ammonium (P = .045). CONCLUSION In patients who have undergone Roux-en-Y gastric bypass, PCC was superior to Citracal Petite in conferring bioavailable calcium and suppressing parathyroid hormone secretion. PCC also provided an alkali load.

Abstract
To standardise possible peri-operative bariatric surgery protocols, a survey was prepared to be filled in by members of the Spanish Society for Obesity (Sociedad Española de Cirugía de la Obesidad) (SECO), and to approve it at the XII National Congress. A total of 47 members of SECO from 14 autonomous communities responded, and it unanimously approved by the Congress. As highly recommended peri-operative procedures, were proposed: full laboratory analysis (98%) with an endocrine study (90%), ECG (96%), chest x-ray (98%), an oesophageal-gastric imaging test (endoscopy or gastro-duodenal transit study (98%), antibiotic prophylaxis (92%) and use of low molecular weight heparins pre-operatively (96%), and for 2 weeks (83%). Pre-surgical, abdominal ultrasound (86%), spirometry (80%), diet (88%) and psychological study (76%), and during surgery, use of elastic stockings (76%), leak tests (92%) and drainages (90%), were established as advisable procedures.

Abstract
BACKGROUND Most bariatric surgery programs in the United States require preoperative psychological evaluations for candidates for surgery. Among those who perform these evaluations is concern that many patients engage in "impression management" or minimizing the symptoms of distress to receive a recommendation to proceed with surgery from the mental health professional. We sought to assess the prevalence of socially desirable responding and its associations with measures of psychological functioning among bariatric surgery candidates at 2 academic medical centers in the United States. METHODS The participants were male (n = 66) and female (n = 293) bariatric surgery candidates who presented for psychological evaluation. The participants completed 2 measures of socially desirable response styles (Marlowe-Crowne Social Desirability Scale and Personality Assessment Inventory Positive Impression Management scale) and standardized measures of anxiety, depression, and alcohol-related problems. RESULTS The participants exhibited elevated scores on the social desirability indicators, with 33.3-39.8% scoring above the recommended cut-score on the Personality Assessment Inventory Positive Impression Management scale and 62.3-67% scoring 1 standard deviation above the standardization mean on the Marlowe-Crowne Social Desirability Scale. Scores on the Marlowe-Crowne Social Desirability Scale and Personality Assessment Inventory Positive Impression Management scale correlated inversely with the clinical measures of anxiety and depression, and the high/low scorers on the social desirability indices exhibited significant differences in anxiety and depression. Thus, elevated scores on the social desirability indices were associated with underreporting of certain clinical symptoms. CONCLUSION A substantial proportion of bariatric surgery candidates appear to present themselves in an overly favorable light during the psychological evaluation. This response style is associated with less reporting of psychological problems and might interfere with the accurate assessment of patient functioning.

Abstract
During the past decade, bariatric surgery has become an increasingly popular treatment option for the growing number of individuals with extreme obesity. For most individuals, the size and durability of the weight loss and improvements in co-morbidity and mortality have far surpassed those typically seen with behavioral modification and pharmacotherapy. A significant minority of patients, however, will experience suboptimal outcomes, including less than expected weight loss, premature weight regain, and frequent vomiting and/or gastric dumping. The reasons for these outcomes are not well understood, but likely involve both behavioral and physiologic processes. The present review highlights current knowledge on the changes in dietary intake and eating behavior that occur after bariatric surgery in terms of the potential threats these changes might pose to long-term postoperative success. The paper also identifies several strategies from the nonsurgical weight loss literature that might help optimize long-term weight maintenance after surgery.

Abstract
OBJECTIVE Although the Diabetes Prevention Program (DPP) and the Finnish Diabetes Prevention Study (FDPS) demonstrated that weight loss from lifestyle change reduces type 2 diabetes incidence in patients with prediabetes, the translation into community settings has been difficult. The objective of this study is to report the first-year results of a community-based translation of the DPP lifestyle weight loss (LWL) intervention on fasting glucose, insulin resistance, and adiposity. RESEARCH DESIGN AND METHODS We randomly assigned 301 overweight and obese volunteers (BMI 25-40 kg/m(2)) with fasting blood glucose values between 95 and 125 mg/dL to a group-based translation of the DPP LWL intervention administered through a diabetes education program (DEP) and delivered by community health workers (CHWs) or to an enhanced usual-care condition. CHWs were volunteers with well-controlled type 2 diabetes. A total of 42.5% of participants were male, mean age was 57.9 years, 26% were of a race/ethnicity other than white, and 80% reported having an education beyond high school. The primary outcome is mean fasting glucose over 12 months of follow-up, adjusting for baseline glucose. RESULTS Compared with usual-care participants, LWL intervention participants experienced significantly greater decreases in blood glucose (-4.3 vs. -0.4 mg/dL; P<0.001), insulin (-6.5 vs. -2.7 μU/mL; P<0.001), homeostasis model assessment of insulin resistance (-1.9 vs. -0.8; P<0.001), weight (-7.1 vs. -1.4 kg; P<0.001), BMI (-2.1 vs. -0.3 kg/m2; P<0.001), and waist circumference (-5.9 vs. -0.8 cm; P<0.001). CONCLUSIONS This translation of the DPP intervention conducted in community settings, administered through a DEP, and delivered by CHWs holds great promise for the prevention of diabetes by significantly decreasing glucose, insulin, and adiposity.

Abstract
BACKGROUND Obesity is a serious health problem that leads to serious physical and psychological problems. The methods used in treating obesity include diet and behavioral changes, pharmacotherapy, and surgery. Laparoscopic adjustable gastric banding (LAGB) and intragastric balloon (IGB) applications are two of the methods used to treat obesity. The aim of this study was to compare the effects of LAGB with those of two consecutive IGB applications in weight loss management of obese patients. METHODS Thirty-two patients (F/M:24/8) admitted in the study were divided into two groups. In the first group of 16 patients, LAGB was performed, and in the other group two consecutive IGBs were applied. Total weight loss, body mass index (BMI), excess weight loss percent (EWL %), and excess body mass index loss percent (EBMIL %) were recorded at months 6, 12, and 18 for both groups. RESULTS At the end of the 6th month, BMI values of LAGB and IGB groups were 36.0 and 30.6 kg/m(2), EWL % were 32.3% and 39.3%, and EBMIL % were 36.3% and 47.1%, respectively. The results were similar. At the end of 12 months, median BMI was 36.6 kg/m(2) for LAGB and 27.5 kg/m(2) for IGB (P<.05). The EWL % and EBMIL % at the end of the 12th month were 57% and 70%, which is significant in favor of IGB. The last evaluation was made at the 18th month of applications, and the three parameters for two applications were found to be similar. CONCLUSIONS The achieved weight losses at the 6th month were similar for both groups. However, at the 12th month, two consecutive IGB applications were more effective. At the end of the 18th month, the results were again similar. Two consecutive IGB applications may be offered to obese patients who do not feel ready for surgery.

Abstract
BACKGROUND Patients undergoing Roux-en-Y gastric bypass (RYGB) surgery are prone to developing bone loss and kidney stones. The goal of the present study was to test the hypothesis that an effervescent formulation of potassium calcium citrate (PCC) would avert metabolic complications by providing bioavailable calcium and alkali. METHODS A total of 24 patients with RYGB underwent a 2-phase crossover randomized trial comparing PCC and placebo. During the last 2 days of each 2-week phase, the serum and 24-hour urine samples were analyzed for calcium and bone turnover markers, acid base status, and urinary stone risk factors. RESULTS Compared with placebo, PCC marginally reduced the serum parathyroid hormone level and significantly decreased urinary deoxypyridinoline by 12% (P <.001) and serum type 1 collagen C-telopeptide by 22% (P <.01). PCC significantly increased the net gastrointestinal alkali absorption, citrate, and pH and significantly lowered the urinary net acid excretion (P <.001). The urinary saturation of uric acid decreased significantly (P <.001). The supersaturation of calcium oxalate and brushite did not change despite an increase in calcium and pH. In untreated urine samples with citrate concentrations altered to mimic those of placebo and PCC, calcium oxalate agglomeration was significantly inhibited by PCC. CONCLUSION In RYGB patients, PCC supplementation inhibited bone resorption by providing bioavailable calcium, reduced the urinary saturation of uric acid, and increased the inhibitor activity against calcium oxalate agglomeration by providing alkali that increased urinary pH and citrate.

Abstract
Obesity is a worldwide epidemic with increasing importance in both industrialised and developing countries. Anaesthesiologists will be increasingly challenged by the care for morbidly and super-obese patients. Prerequisites for an optimal perioperative care are a suitable and adapted environment both on the ward and in the operating theatre, the timely and comprehensive preoperative evaluation focussed on co-morbidities, such as diabetes, coronary artery disease and obstructive sleep apnoea syndrome and appropriate equipment for positioning, anaesthesia and surgery. To deliver an adequate standard of care, anaesthesiologists must consider the pharmacokinetic characteristics and pathophysiological sequelae of obesity. Careful preoxygenation, special positioning, adequate monitoring and adapted intra-operative ventilation are key issues for a successful perioperative care. While co-morbidities are frequent in the obese, overall morbidity and mortality up to a body mass index (BMI) < or = 40 kg m(-2) are not significantly increased compared with lean patients.

Abstract
The biliopancreatic diversion is currently the maximum variant of bariatric surgery. It presents several opportunities of typical surgical complications, beside the risks generally prevailing in bariatric surgery. In addition, there is the procedure-immanent risk of development of nutritional deficiencies in the long-term process, at significant percentages. These deficiencies can, to a great extent, be avoided by consistent supplementation within the scope of a structured follow-up program; they can also be corrected by a substitution therapy. In the future, the risk of malnutrition can possibly be lowered by technically modified procedures with equal bariatric effectiveness. Considering the very good long-term results with regard to stable weight reduction in connection with a high recovery rate of the comorbidities, combined with a consistent postal-surgical management, the problem of malnutrition appears to be of minor importance. However, an appropriate compliance of the patient is also required.

Abstract
With the increasing number of bariatric surgeries being performed, multiple specialties encounter bariatric patients. This article gives an overview of the comprehensive evaluation and preoperative preparation of a bariatric patient. Medical, psychological, and behavioral evaluation is discussed. The role of routine preoperative endoscopy is controversial but can be very important and may alter the operation performed. Immediate postoperative care is also addressed. Undergoing bariatric surgery is a lifelong commitment, and frequent follow up with reinforcement and monitoring for nutritional deficiencies is extremely important.

Abstract
The prevalence of obesity is increasing and is co-epidemic with type 2 diabetes mellitus (T2DM). Treatment of obesity has been less than adequate, particularly when managing morbidly obese patients. Research on T2DM has shown a number of new pharmacologic therapies along with the rapid employment of bariatric surgery. Improvement of T2DM, including its remission, after bariatric surgery has been recognized for more than a decade. However, not all procedures are the same. Restrictive procedures, malabsorptive procedures, or a combination of both procedures have their own categorical risks and benefits. Which procedure to choose has to do with many patient selection factors, notwithstanding insurance coverage. Based on operative and postoperative mortality data, laparoscopically assisted gastric bypass (LAGB) has been shown to be the safest bariatric surgery procedure. However, the Roux-en-Y gastric bypass procedure is one of the most widely used for obese patients with T2DM. The mechanisms involved in weight loss and improved blood glucose control appear to involve increased insulin sensitivity, decreased lipotoxicity/inflammation, and changes in gut hormones/incretins. The safety of bariatric procedures has improved; complication rates are low and mortality is < 1% for all procedures. As a result of the dramatic, positive impact of bariatric procedures on T2DM in obese patients, physicians should be cautious during patient selection to avoid performing the procedure on patients who are overzealous about reported outcomes, but who are not candidates for the procedure. Other data gaps still exist regarding diabetes surgery, which must be filled using data from well-designed, well-implemented randomized controlled clinical trials. In the future, it will be prudent to compare surgical interventions with other rigorous medical interventions in more robust studies. A combination of surgical, medical, and behavioral interventions should be considered for treating obese patients with T2DM.

Abstract
Surgical interventional strategies for the treatment of obesity are being implemented at an increasing rate. The safety and feasibility of these procedures are questionable for most overweight or obese individuals. The use of long-term pharmacotherapy options, on the other hand, can target a greater portion of the obese population and provide early intervention to help individuals maintain a healthy lifestyle to promote weight loss. Medications that act on the central serotonergic pathways have been a relative mainstay for the treatment of obesity for the last 35 years. The clinical efficacy of these drugs, however, has been encumbered by the potential for drug-associated complications. Two drugs that act, albeit by different mechanisms, on the central serotonergic system to reduce food intake and decrease body weight are sibutramine and lorcaserin. Sibutramine is a serotonin and norepinephrine reuptake inhibitor, whereas lorcaserin is a selective 5HT2C receptor agonist. The recent worldwide withdrawal of sibutramine and FDA rejection of lorcaserin has changed the landscape not only for serotonin-based therapeutics specifically, but for obesity pharmacotherapy in general. The purpose of this review is to focus on the importance of the serotonergic system in the control of feeding and its potential as a target for obesity pharmacotherapy. Advances in refining and screening more selective receptor agonists and a better understanding of the potential off-target effects of serotonergic drugs are needed to produce beneficial pharmacotherapy.

Abstract
Bariatric surgery has proven to be a life-saving measure for some, but for others it has precipitated a plethora of metabolic complications ranging from mild to life-threatening, sometimes to the point of requiring surgical revision. Obesity was previously thought to be bone protective, but this is indeed not the case. Morbidly obese individuals are at risk for metabolic bone disease (MBD) due to chronic vitamin D deficiency, inadequate calcium intake, sedentary lifestyle, chronic dieting, underlying chronic diseases, and the use of certain medications used to treat those diseases. After bariatric surgery, the risk for bone-related problems is even greater, owing to severely restricted intake, malabsorption, poor compliance with prescribed supplements, and dramatic weight loss. Patients presenting for bariatric surgery should be evaluated for MBD and receive appropriate presurgical interventions. Furthermore, every patient who has undergone bariatric surgery should receive meticulous lifetime monitoring, as the risk for developing MBD remains ever present.

Abstract
BACKGROUND Although pre-surgical psychological evaluations are commonly administered to patients considered for weight loss surgeries, the value of these evaluations for predicting weight loss success has been questioned. In this study, we addressed this issue by examining patient's total number of psychiatric indicators rather than individual psychological factors as predictors of weight loss/weight regain. METHODS Sixty adult veterans completed gastric bypass surgery or laparoscopic gastric banding after completing a multidisciplinary evaluation for surgical clearance, including a psychological assessment. Patients were subsequently followed for 24 month to examine changes in weight, body mass index, and risk of weight regain. RESULTS Nearly three fourths of the sample carried either a single (40.0%) or multiple psychiatric diagnoses (33.4%). Nearly half (47.5%) of the sample ceased losing weight after 1 year, with 29.5% regaining weight after this point. Neither psychiatric nor biomedical factors effectively predicted 1-year weight loss totals; however, we observed a significant linear relationship between the number of psychiatric factors and post-1-year weight changes (r = 0.33, p = 0.01). After adjusting for demographic and biomedical factors, patients with two or more psychiatric diagnoses were found to be significantly more likely to experience weight loss cessation or weight regain after 1-year (OR = 6.4, 95% CI = 1.3-12.4) relative to those with zero or one psychiatric diagnosis. CONCLUSIONS Assessing mental health factors in terms of the total number of psychiatric conditions improved the prediction of weight loss surgery outcomes in this veteran sample. An expanded model for understanding how psychological factors may affect weight loss surgery may improve the utility of pre-bariatric psychological assessments.

Abstract
Interest in vitamin D has increased recently because of its role on multiple biologic mechanisms and the high prevalence of deficits, particularly in obese individuals. The epidemic of morbid obesity has led to a growing number of bariatric surgical procedures, the only therapeutic modality with a reasonable chance of success on a long-term basis. Vitamin D status following bariatric surgery depends on several interacting factors and should be monitored carefully. We review vitamin D, calcium and parathyroid hormone dynamics following the main types of bariatric surgery and the guidelines for the postoperative periodic assessment and therapy.

Abstract
BACKGROUND Successful weight loss after bariatric surgery depends on the patient's adherence to prescribed eating and physical activity behaviors. However, few studies have assessed patients' adherence to the behavioral recommendations and most have used retrospective self-report measures. The present study is the first to use ecological momentary assessment (EMA) via a palmtop computer to assess bariatric surgery patients' eating and activity behaviors in real-time in the natural environment. The study was conducted at Miriam Hospital (Providence, RI). METHODS A total of 21 patients (14 laparoscopic adjustable gastric banding and 7 Roux-en-Y; 81% women; mean age 48.5 yr) were studied 6.1 ± 2.1 months postoperatively. The participants used a palmtop computer for 6 days to report on all eating and physical activity episodes as they occurred in the natural environment. RESULTS All participants demonstrated good compliance with the EMA, using the device on ≥5 full days. Most participants (94.8%) adhered to the recommendation to not drink while eating, and most took their vitamin supplements and medication as prescribed (85.7% and 90.5%, respectively). Few (4.8%) participants ate the recommended ≥5 meals daily, most participants exceeded the recommended portion sizes during meals and snacks (100% and 72.0% of the participants, respectively), and 47.6% of the participants consumed ≥5 servings of fruit and vegetables daily. Only 15.8% regularly consumed adequate liquids. Only 23.8% of participants engaged in moderate to vigorous physical activity for ≥30 minutes daily, as recommended. CONCLUSION The EMA results suggested that adherence to the recommended behaviors varied considerably, depending on the behavior, with greater adherence to simple versus complex behaviors. EMA might eventually be a useful tool to help optimize the outcomes of bariatric surgery by identifying behavioral targets for additional monitoring and intervention.

Abstract
BACKGROUND Few empirical reports of studies examining the association between bariatric after care support group attendance and weight loss outcomes have been published. The present study investigated the association between the number of support group meetings attended and percentage of excess weight loss at 12 months after gastric banding surgery. The setting was a private practice at which no-cost, professionally led support group meetings were held weekly. METHODS The medical records and support group attendance logs were examined for the dates of attendance, frequency of attendance (or no attendance) in relation to the percentage of excess weight loss (n = 102; 88.2% women; mean age 45.6 ± 11.3 years; mean baseline body mass index 46.4 ± 8.8 kg/m(2)). Linear regression models were used to assess the relationship between the number of group meetings attended and the percentage of excess weight of loss with age and baseline body mass index used as optional independent variables. RESULTS A significant linear relationship was found between support group meeting attendance and the percentage of excess weight loss with simple regression analysis (adjusted R(2) = .061, P = .007), with age (adjusted R(2) = .100, P = .002) and the baseline body mass index added to the model (adjusted R(2) = .072, P = .011). CONCLUSION The results of the present study add to the growing evidence of the positive relationship between the frequency of support group attendance and the percentage of excess weight loss. Future studies should examine patient motivational characteristics in relation to support group participation and other aspects of compliance with aftercare recommendations to investigate unique effects of each part of the treatment program on weight loss outcomes.

Abstract
Although obesity is considered to be a medical condition, psychosocial variables influence its development, course, and treatment. To date, obesity research focuses heavily on the associated physical problems and the identification of effective treatments. While an array of behavioral, pharmacological and surgical treatments has been developed, their ability to demonstrate long-term weight losses is not convincing. Thus, there has been a shift towards the identification of psychological and social factors that may assist in the prediction of successful treatments, most notably in the surgical treatment of obesity. As a result, less emphasis has been placed on post-treatment psychosocial influences. As the treatment of obesity becomes increasing multidimensional, the need for attention to psychosocial factors and the involvement of mental health providers increases. For the allied or mental health provider, a comprehensive understanding of obesity's physical, psychological and social basis is vital to ensure proper assessment or treatment, as it is warranted.

Abstract
BACKGROUND Since the 1991 recommendation by the National Institutes of Health-sponsored consensus development conference, preoperative psychosocial evaluation of weight loss surgery patients has been adopted by >80% of weight loss surgery programs. Although some published suggestions for conducting evaluations exist, no formal guidelines have been published specifying the qualifications, content knowledge, or clinical experience for the behavioral health professionals who conduct them. As a result, the backgrounds of behavioral health professionals working with bariatric surgery patients are varied, and no mechanism exists to ensure consistent quality of care. To obtain expert opinion on this issue, a survey of the American Society for Metabolic and Bariatric Surgery membership was conducted using an Internet-based survey. METHODS American Society for Metabolic and Bariatric Surgery members of all disciplines were invited by electronic mail to complete an Internet-based survey. Separate forms were created for behavioral health providers and for members of other disciplines. RESULTS A total of 409 American Society for Metabolic and Bariatric Surgery members responded (60 behavioral health and 349 nonbehavioral health). Of the 409 respondents, 95% indicated a belief that it is important for behavioral health providers to have specialty knowledge; 87% indicated a belief that specialty experience is important; and 70.6% favored the development of a specialty credential for bariatric behavioral health providers to regulate the quality of patient care. However, the respondents also reported concerns about creating such a credential. CONCLUSION Our results reflect widespread opinion that the provision of bariatric behavioral health services requires specialty knowledge and experience and that a credentialing system would help regulate the standard of care in the field. However, some concerns about credential development remain.

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
BACKGROUND Biliopancreatic diversion with duodenal switch (DS) has been the standard surgical approach for the treatment of morbidly obese patients at our institution since the early 1990 s. The published data, however, have shown the use of the DS to be limited to the treatment of super-morbidly obese patients (body mass index [BMI] ≥ 50 kg/m(2)). The aim of the present study was to present our long-term results with the DS in patients with an initial BMI of <50 kg/m(2). METHODS This was a retrospective study of all patients with a BMI <50 kg/m(2) who had undergone DS from June 1992 to May 2005. The data are reported as the mean ± standard deviation. RESULTS The data from 810 consecutive patients, with a mean initial BMI of 44.2 ± 3.6 kg/m(2), were reviewed. The mean follow-up was 103 ± 49 months. Major perioperative complications occurred in 5.8% of patients, including 5 deaths (.6%). The initial excess weight loss was 76% ± 22%, and the excess weight loss was >50% in 89% of patients. Malnutrition required readmission in 4.3% and surgical revision in 1.5%. The prevalence of severe albumin deficiency (<30 g/L) was 1.1%, hemoglobin deficiency (<100 g/L), 1.6%, iron deficiency (<4 mmol/L) 2.1%, and calcium deficiency (<2 g/L) 3%. The percentage of patients "very satisfied" with the global result was 91%, and 37% would have preferred to lose more weight. CONCLUSION These results showed that in non super-obese patients, DS was very efficient in terms of weight loss and patient satisfaction. This was associated with a 1.5% risk of revision for malnutrition. However, nutritional deficiencies required frequent readjustment of supplements, particularly for calcium, vitamin A, and vitamin D.

Abstract
BACKGROUND Mental health professionals have become increasingly involved in working with bariatric surgical candidates, particularly in performing preoperative psychological evaluations to clear candidates for surgery. The objective of the present study was to examine the concordance of the psychiatric diagnoses obtained during routine clinical evaluation before bariatric surgery and the diagnoses obtained separately at a research facility using the Structured Clinical Interview for DSM (Diagnostic and Statistical Manual of Mental Disorders)-IV axis I disorders. METHODS The study included 68 consecutively enrolled bariatric surgical candidates who had participated in the Longitudinal Assessment of Bariatric Surgery-3 study. The Structured Clinical Interview for DSM disorders data obtained from the research assessments were compared with the diagnostic data from the routine preoperative psychiatric evaluations. The congruence of the current and lifetime diagnoses was assessed using Cohen's coefficient kappa. RESULTS Considerable variability was found among the major diagnostic categories, with generally poor agreement found for the current diagnoses. The kappa coefficients tended to be larger for the lifetime diagnoses. The agreement was moderate for any lifetime mood disorder, with a kappa value of 0.45. Regarding any lifetime anxiety, substance use, and eating disorder, the clinical diagnoses rarely concurred with the results from the Structured Clinical Interview for DSM disorders, with a kappa statistic of 0.30, 0.36, and 0.32, respectively. CONCLUSION The congruence between the diagnoses assigned during the routine clinical psychiatric evaluations and research assessment using the Structured Clinical Interview for DSM disorders was surprisingly low. These conclusions should be considered tentative, given the interval and the possibility of treatment having occurred between the 2 evaluations. Overall, these data raise interesting questions concerning the use of unstructured psychiatric evaluations before bariatric surgery.

Abstract
PURPOSE Roux-en-Y gastric bypass surgery is associated with an increased risk of nephrolithiasis but obesity itself is a known risk factor for kidney stones. To assess the mechanism(s) predisposing to nephrolithiasis after Roux-en-Y gastric bypass we compared urinary tract stone risk profiles in patients who underwent the procedure and normal obese individuals. MATERIALS AND METHODS In this cross-sectional study urine and serum biochemistry was evaluated in 19 nonstone forming patients after Roux-en-Y gastric bypass and in 19 gender, age and body mass index matched obese controls without a history of nephrolithiasis. RESULTS Compared with obese controls surgical patients had significantly higher mean +/- SD urine oxalate (45 +/- 21 vs 30 +/- 11 mg daily, p = 0.01) and lower urine citrate (358 +/- 357 vs 767 +/- 307 mg daily, p <0.01). The prevalence of hyperoxaluria (47% vs 10.5%, p = 0.02) and hypocitraturia (63% vs 5%, p <0.01) was significantly higher in surgical patients, who also had significantly lower urine calcium than obese controls (115 +/- 93 vs 196 +/- 123 mg daily, p = 0.03). The calcium oxalate urine relative supersaturation ratio was not significantly different between the 2 groups. CONCLUSIONS Almost half of patients with Roux-en-Y gastric bypass without a history of nephrolithiasis showed hyperoxaluria or hypocitraturia. This prevalence was significantly higher than in body mass index matched controls. These risk factors were negated by lower urine calcium excretion in patients with Roux-en-Y gastric bypass.

Abstract
BACKGROUND In 2006, Brighton Hospital (Brighton, Michigan), a comprehensive substance abuse treatment facility, began observing increasing admissions who reported a history of bariatric surgery. Data on the magnitude of this postoperative outcome is lacking. The hospital instituted procedures to better track this variable in the electronic medical records at admission to estimate the prevalence of bariatric surgery history among substance abuse treatment admissions. METHODS The data analyzed for the present report included the electronic medical record data obtained from 7199 patients admitted from 2006 to 2009 and the chart review data from 54 bariatric patients and 54 controls. RESULTS The findings suggested that 2-6% of recent admissions were positive for a bariatric surgery history. The substance abuse treatment patients with a bariatric surgery history were significantly more likely to be women and nonsmokers. The bariatric and nonbariatric patients were equally likely to have been diagnosed with alcohol dependence; however, bariatric patients were significantly more likely to also have a diagnosis of alcohol withdrawal. Relative to the matched control cases, the alcohol-dependent bariatric patients reported consuming a significantly greater maximum quantity of drinks per drinking day. CONCLUSION A bariatric surgery history might be overrepresented in substance use programs and such patients' recovery efforts might pose unique challenges.

[PMID: 20189470 DOI: 10.1016/j.soard.2009.11.017] [Citation(s) in RCA: 48] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2009] [Revised: 11/22/2009] [Accepted: 11/29/2009] [Indexed: 01/07/2023]
Abstract
BACKGROUND Research has demonstrated that laparoscopic Roux-en-Y gastric bypass patients with a lifetime history of a mood disorder have a lower percentage of excess weight loss (%EWL) compared with patients without this lifetime history. No studies have examined the effect of psychiatric history on postoperative outcomes among laparoscopic sleeve gastrectomy (LSG) patients. The objectives of the present study were to determine whether mood disorders relate to the first year of weight loss for patients undergoing LSG at an academic medical center. METHODS A total of 104 patients (78.6% white and 71.2% women), with a median body mass index of 60.35 kg/m(2) (range 31.37-129.14) underwent LSG. The patients were prospectively followed up at 1, 3, 6, 9, and 12 months. The semistructured preoperative psychiatric evaluations demonstrated that 43.1% had a current, and 62.5% a lifetime, diagnosis of a mood disorder. RESULTS LSG patients with current mood disorders had a significantly lower %EWL than patients without a psychiatric diagnosis at the 1-, 3-, 6-, and 9-month follow-up visits. LSG patients with a lifetime history of a mood disorder had a significantly lower %EWL than patients without psychiatric diagnosis at the 1-, 9-, and 12-month follow-up examinations. However, after removing patients with bipolar disorder from the analyses, no significant differences were found in the %EWL between patients with and without a lifetime history of depressive disorders. CONCLUSION Consistent with the laparoscopic Roux-en-Y gastric bypass findings, a lifetime history of mood disorders appears to be associated with significantly less weight loss in LSG patients. These findings highlight the importance of the psychiatric assessment in bariatric patients. Additionally, patients with a current or lifetime history of mood disorders might need additional pre- and postoperative care to improve their outcomes.

Abstract
OBJECTIVE To review how bariatric surgery in obese patients may effectively treat adiposopathy (pathogenic adipose tissue or 'sick fat'), and to provide clinicians a rationale as to why bariatric surgery is a potential treatment option for overweight patients with type 2 diabetes, hypertension, and dyslipidaemia. METHODS A group of clinicians, researchers, and surgeons, all with a background in treating obesity and the adverse metabolic consequences of excessive body fat, reviewed the medical literature regarding the improvement in metabolic disease with bariatric surgery. RESULTS Bariatric surgery improves metabolic disease through multiple, likely interrelated mechanisms including: (i) initial acute fasting and diminished caloric intake inherent with many gastrointestinal surgical procedures; (ii) favourable alterations in gastrointestinal endocrine and immune responses, especially with bariatric surgeries that reroute nutrient gastrointestinal delivery such as gastric bypass procedures; and (iii) a decrease in adipose tissue mass. Regarding adipose tissue mass, during positive caloric balance, impaired adipogenesis (resulting in limitations in adipocyte number or size) and visceral adiposity are anatomic manifestations of pathogenic adipose tissue (adiposopathy). This may cause adverse adipose tissue endocrine and immune responses that lead to metabolic disease. A decrease in adipocyte size and decrease in visceral adiposity, as often occurs with bariatric surgery, may effectively improve adiposopathy, and thus effectively treat metabolic disease. It is the relationship between bariatric surgery and its effects upon pathogenic adipose tissue that is the focus of this discussion. CONCLUSIONS In selective obese patients with metabolic disease who are refractory to medical management, adiposopathy is a surgical disease.

The impact of socioeconomic factors on patient preparation for bariatric surgery. Obes Surg 2009; 19:1089-95. [PMID: 19517200 DOI: 10.1007/s11695-009-9889-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2009] [Accepted: 05/26/2009] [Indexed: 01/14/2023]
Abstract
BACKGROUND Socioeconomic factors (SEF) influence bariatric surgery access and outcomes perhaps because of variations in patient knowledge and behaviors. This study examines the associations between income, formal education, race, health insurance, employment status, and patient self-educational and behavioral activities prior to bariatric surgery. METHODS From March 2005 through January 2006, we surveyed 127 individuals who contacted our office seeking bariatric surgery. Study participants were asked to report their income, formal education, health insurance, employment status, height, weight, and standard demographic data. The type and number of self-educational resources utilized were elicited; a description of current eating and exercise behaviors was obtained; and an objective assessment (OA) of knowledge of the risks of both obesity and bariatric procedures was completed. RESULTS The most valuable self-educational resource cited by respondents was the internet (41.2%) and was unaffected by SEF. Individuals who were employed, privately insured, white, and earning>or=$20,000/year reported using a greater number of self-educational resources than their peers, while subjects who were privately insured, had higher formal educational levels, and earned>or=$20,000/year demonstrated greater proficiency on the OA instrument. Engagement in healthy eating and exercise behaviors was unaffected by any SEF. On multivariate analysis, higher income was the sole significant factor directly related to the number of educational resources utilized and proficiency on OA. CONCLUSION Obese patients from lower-income households may benefit from additional preoperative education. All individuals, regardless of socioeconomic factors, must be encouraged to implement healthy eating and exercise behaviors preoperatively.
