Abstract
ABSTRACT The field of bariatric and metabolic surgery has changed rapidly over the past two decades, with an exponential increase in case volumes being performed because of its proven efficacy for morbid obesity and obesity-related comorbidities. Although this increased volume of procedures has been accompanied by significant decrease in postoperative complication rates, there are numerous potential complications after bariatric surgery that may require urgent or emergent surgical evaluation or interventions. Many of these risks extend well beyond the early postoperative period and can present months to years after the index procedure. Acute care surgeons are increasingly covering most or all of the emergency general surgery services at many centers and must be familiar with the numerous bariatric surgical procedures being performed and their individual complication profile to provide optimal care for these frequently challenging patients. This article provides a focused and concise review of the common bariatric procedures being performed, their early and late complication profiles, and a practical guide to the optimal diagnostic evaluations, surgical interventions, and perioperative management options. The author group includes both acute care surgeons and bariatric surgeons with significant experience in the emergency management of the complicated postbariatric surgical patient.

Abstract
INTRODUCTION Most surgeons who perform single-anastomosis duodeno-ileal switches (SADI-S) use a pre-determined common channel length without measuring total bowel length (TBL). However, TBL varies between patients, and a standardized common channel length could contribute to malabsorptive complications and reoperations following SADI-S. The purpose of this study was to determine whether using a TBL measurement protocol to individualize common channel length would be associated with reduced reoperations and complications. METHODS A prospectively maintained data registry was retrospectively reviewed to identify all patients who underwent SADI-S between September 2017 and February 2022. In April 2021, we began using TBL measurements during SADI-S with 40% of the TBL used as the length for the common channel. Outcomes pre-TBL and post-TBL measurement protocol were compared. RESULTS A total of 119 SADI-S recipients (59 pre-TBL; 60 post-TBL) were included. The pre-TBL group had a higher frequency of reoperations (23.7% vs 1.7%, p < 0.001) and late complications (29.3% vs 3.3%, p < 0.001). The mean time to reoperation was 13.7 months in the pre-TBL group and 6.7 months in the post-TBL group (p = 0.347). Patients in the post-TBL group had significantly higher serum albumin levels at 3 months (4.2 g/dL vs 3.5 g/dL, p < 0.001), 6 months (4.1 g/dL vs 3.6 g/dL, p < 0.001), and 12 months (4.2 g/dL vs 3.8 g/dL, p = 0.023) postoperatively when compared to the pre-TBL group. CONCLUSION Using TBL measurements to individualize common channel length was associated with a significant reduction in reoperations and late complications following SADI-S.

Safety of biliopancreatic diversion with duodenal switch in patients with body mass index less than 50 kg/m 2. Surg Endosc 2022; 37:3046-3052. [PMID: 35922604 DOI: 10.1007/s00464-022-09483-5] [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: 03/16/2022] [Accepted: 07/13/2022] [Indexed: 10/16/2022]
Abstract
INTRODUCTION Biliopancreatic diversion with duodenal switch (BPD-DS) has often been reserved for patients with BMI > 50 kg/m2. We aim to assess the safety of BPD-DS in patients with morbid obesity (BMI 335 kg/m2 and < 50 kg/m2) using a 150-cm common channel (CC), 150-cm Roux limb, and 60-fr bougie. METHODS A retrospective review was performed on patients with a BMI < 50 mg/k2 who underwent a BPD-DS in 2016-2019 at a single institution. Limb lengths were measured with a laparoscopic instrument with minimal tension. Sleeve gastrectomy was created with 60-fr bougie. Variables were compared using paired t test, Chi-square analysis or repeated measures ANOVA where appropriate. RESULTS Forty-five patients underwent BPD-DS. CC lengths and Roux limb lengths were 158 ± 20 cm and 154 ± 18 cm, respectively. Preoperative BMI was 44.9 ± 2.3 kg/m2 and follow-up was 2.7 ± 1.4 years. One patient required reoperation for bleeding and died from multiorgan failure and delayed sleeve leak. There was 1 (2.2%) readmission for contained anastomotic leak and 2 ED visits (4.5%) within 30 days. There were no marginal ulcers, limb length revisions, or need for parental nutrition. Percent excess weight loss was 67.2 ± 19.7%. 88.9% (N = 8), 86.6% (N = 13), and 55.5% (N = 5) of patients had resolution or improvement of their diabetes mellitus type II, hypertension, and hyperlipidemia, respectively. 40% (N = 4) of patients had resolution of their gastroesophageal reflux disease (GERD) and 11.4% (N = 5) developed de novo GERD. 32% (N = 14) of patients had vitamin D deficiency and 25% (N = 11) experienced zinc deficiency. CONCLUSION BPD-DS may be considered in patients with BMI < 50 kg/m2 with 150-cm CC, 150-cm Roux limb, and a 60-fr bougie sleeve gastrectomy. There was sustained weight loss and no protein calorie malnutrition, but Vitamin D and zinc deficiency remained a challenge. Careful patient selection and proper counseling of the risks and benefits are necessary.

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

Abstract
BACKGROUND The use of one anastomosis gastric bypass (OAGB) is rapidly spreading. Concerns about biliary reflux and malabsorption with consequent nutritional deficits exist, so studies on biliopancreatic limb (BPL) adequate length in OAGB are required to balance excess weight loss in percentage (% EWL), resolution of comorbidities, and nutritional deficit. The purpose was to evaluate, at 2 years after OAGB, the effects of BPL length on weight loss, resolution of comorbidity, and nutritional deficiencies in patients. METHODS From January 2015 to January 2017, 180 patients were collected into three groups based BPL length: group A, 150 cm; group B, 180 cm; and group C, 200 cm. Aims were to compare %EWL, co-morbidity resolution rates, nutritional parameters, and morbidity/mortality in the three groups. RESULTS The total number of patients was 180: 60 for each group. One hundred seventy-two (95%) patients attended the 1-year follow-up (group A = 58; group B = 58, group C = 56). One hundred fifty-seven (87%) patients attended the 2-year follow-up (group A = 52 (87%); group B = 53 (88%); group C = 52 (87%)). There was no statistically significant difference in %EWL, %TWL, T2DM, and hypertension resolution rates among the groups. About vitamin deficiency, differences were not statistically significant. Iron and ferritin deficiency rate were statistically significant only between A and C groups. CONCLUSIONS According to our evidence, standardization of BPL length shorter than 200 cm is suggested, potentially minimizing malnutrition-related outcomes. Our study seems to show that a BPL of 150-180 cm is safe and effective in terms of EWL and comorbidity improvement with low malnutrition effects even in BMI > 50.

Abstract
Surgical interventions for weight-related diseases (SWRD) may have substantial and sustainable effect on weight reduction, also leading to a higher remission rate of type 2 diabetes (T2D) mellitus than any other medical treatment or lifestyle intervention. The resolution of T2D after Roux-en-Y gastric bypass (RYGB) typically occurs too quickly to be accounted for by weight loss alone, suggesting that these operations have a direct impact on glucose homeostasis. The mechanisms underlying these beneficial effects however remain unclear. Recent research suggests that changes in the concentrations of plasma bile acids might contribute to these metabolic changes after surgery. In this review, we aimed to outline the potential role of bile acids in SWRD. We systematically reviewed MEDLINE, SCOPUS, and Web of Science for articles reporting the effect of SWRD on outcomes published between 1969 and 2016. We found that changes in circulating bile acids after surgery may play a major role through activation of the farnesoid X receptor A (FXRA), the fibroblast growth factor 19 (FGF19), and the G protein-coupled bile acid receptor (TGR5). Bile acid concentration increased significantly after RYGB. Some studies suggest that a transitory decrease occurs at 1 week post-surgery, followed by a gradual increase. Most studies have shown the increase to be proportionate by all bile acid subtypes. Bile acids can regulate glucose metabolism through the expression of TGR5 receptor in L cells, resulting in a release of glucagon-like peptide 1 (GLP-1). It may also induce the synthesis and secretion of FGF19 in ileal cells, thereby improving insulin sensitivity and regulating glucose metabolism. All the present SWRD are involved with changes in food stimulation to the stomach. This implies that discovering and developing the antagonists to TGR5 and FXRA may effectively control metabolic syndrome and the elucidation of the mechanisms underlying the physiological effects related to weight loss and T2D remission after surgery may help to identify new drug targets.

Abstract
OBJECTIVE The aim of the study was to report 10+ year outcome of laparoscopic biliopancreatic diversion with duodenal switch (LDS), with special focus on quality of life. BACKGROUND: Reports on long-term morbidity and quality of life after LDS are rare. METHODS Records of all patients who underwent LDS 10+ years ago were analyzed. Patients were contacted to answer a questionnaire based on Bariatric Analysis and Reporting Outcome System. Blood work was reported when performed within the past year. RESULTS Of the 153 patients who underwent LDS, follow-up was available for 113 patients (78.5%). Mean follow-up was 130.2 ± 4.6 months. Percentage total weight loss was 40.7 ± 10.8%. Weight loss was greatest in the super obese category (BMI > 50 kg/m). Remission rate for type 2 diabetes was 87.5% (21/24) and for arterial hypertension 80.9% (38/47). Dyslipidemia remission rates were 93.3% (28/30) for total cholesterol, 89.7% (26/29) for triglycerides, and 95.0% (19/20) for low-density lipoprotein cholesterol. However, 42.5% of the patients needed reoperation, including 10.6% for correction of protein malnutrition, the latter exclusively in non-super obese individuals. Most common deficiencies concerned vitamin A and D, iron, and zinc. De novo gastroesophageal reflux disease was reported in 43.8%. The Bariatric Analysis and Reporting Outcome System score was good at 4.9 ± 2.2, and 82.3% of participants would choose the procedure again. CONCLUSIONS LDS is a very effective metabolic procedure, at the cost of occasional protein and other nutritional deficiencies. Outcome in the long term is best in super obese patients. Overall quality of life is good. The high reoperation rate and incidence of gastroesophageal reflux disease are concerning.

Abstract
BACKGROUND Biliopancreatic diversion with duodenal switch (BPD-DS) with a 100-cm common channel has been our treatment of choice for morbid obesity since the early 1990s. This procedure offers excellent long-term weight loss but can be associated with significant side effects. OBJECTIVES To assess the effect on clinical and nutritional parameters of increasing the common channel to 200 cm. SETTINGS University-affiliated tertiary care center. METHODS Patients who underwent a BPD-DS with a 200-cm common channel (study group, n = 36) were matched 1:1 for age, sex, body mass index (BMI), and main co-morbidities with patients who underwent a BPD-DS with a 100-cm common channel (control group). The strict alimentary limb was 150 cm in both groups. RESULTS The mean age was 55±9 versus 53±7 years (P = .3), with 50% women and a BMI of 49±8 kg/m(2) versus 50±6 kg/m(2) (P = .9). Follow-up rate was 97%, with a minimum follow-up of 3 years. There were no significant differences in the remission rate of major co-morbidities between the 2 groups. At 3 years, the excess weight loss was 61±22% versus 68±18% (P = .18) and the total weight loss was 33±11% versus 38±9% (P = .055) in the study group versus control group, respectively. The study group had a lower incidence of severe protein deficiency (11% versus 19%, P = .3) and hyperparathyroidism (17.1% versus 35.3%, P = .17); required a lower amount of vitamins A and D (P<.05); and had a decreased number of daily bowel movements (2.0 versus 2.9, P = .03). CONCLUSION In this population, BPD-DS with a 200-cm common channel offered similar remission rate of co-morbidities compared with standard BPD-DS. It was associated with similar weight loss at nadir, followed by a more significant weight regain. It might yield a lower rate of nutritional complications. Long-term randomized data are needed to detect other potential advantages.

Abstract
BACKGROUND This retrospective study compares the clinical and nutritional outcomes of 100 morbidly obese patients who underwent biliopancreatic diversion (BPD) with common (CC) and alimentary channel (AC) length, respectively, 50/250 and 80/200 cm. METHODS One hundred patients who received BPD from October 2006 to November 2011 were identified from a database of bariatric procedures performed at the University Hospital of Messina, and the outcomes in terms of weight loss and morbidity were compared. Forty morbidly obese patients underwent BPD with CC 80 cm and AC 200 cm (group 1) and 60 morbidly obese patients underwent BPD with CC 50 cm and AC 250 cm (group 2). RESULTS A gradual weight loss was observed in both groups during the first 3 years after the operation without any significant difference between the two groups. Two cases of protein malnutrition occurred in the group 2 (3 %) due to poor patient compliance in terms of adequate dietary protein intake. Sideropenic anemia was found in 42 % of obese patients in group 2 versus 22.5 % in group 1 at third-year follow-up despite adequate supplementation (p = 0.047). Diarrhea occurred more frequently with a shorter CC. Lipophilic vitamin deficiencies occurred more frequently with a shorter CC despite adequate oral supplementation. CONCLUSIONS In the medium term, our series showed that shorter CC was associated with no weight loss advantage but with higher morbidity rate, especially in young and fertile women. We recommend a longer CC (80 cm) to be performed especially in this sub-population of obese patients.

Abstract
Background The increasing prevalence of obese patients will lead to a more frequent use of bariatric procedures in the future. Compared to conservative medical therapy, bariatric procedures achieve greater weight loss and superior control of comorbidities, resulting in improved overall mortality. Methods A search for current literature regarding mechanisms, indications, and outcomes of bariatric surgery was performed. Results In order to care for patients after bariatric surgery properly, it is important to understand its mechanisms of action and effects on gastrointestinal physiology. Recent investigations indicate that the beneficial effects of bariatric procedures are much more complex than simply limiting food intake or an associated malabsorption. Changes in gastrointestinal hormone secretion, energy expenditure, intestinal bacterial colonization, bile acid metabolism, and epigenetic modifications resulting in altered gene expression are likely responsible for the majority of the beneficial effects of bariatric surgery. Malabsorptive bariatric procedures divert the flow of bile and pancreatic enzymes from food and therefore limit the digestion and absorption of nutrients, resulting in reduced calorie intake and subsequent weight loss. Essential micronutrients such as vitamins and trace elements are also absorbed to a lesser extent, potentially leading to severe side effects. Conclusion To prevent malnutrition, dietary supplementation and regular control of micronutrient levels are mandatory for patients undergoing malabsorptive bariatric procedures, in whom the fat-soluble vitamins A and D are commonly deficient.

Abstract
Background Several studies indicate that increasing the alimentary limb length in gastric bypass surgery produces only a minor improvement of excess BMI loss. Few studies have addressed the efficacy of increasing the length of the pancreatico-biliary limb. Methods Here, we present a prospective randomized study of 187 consecutive laparoscopic Roux-Y gastric bypass operations operated over 2 years (2004–2005) in Iceland. The patients were operated with a gastric bypass with either a 2-m biliopancreatic (BP)-limb and a 60-cm alimentary (A)-limb (n = 93) or with a 150-cm A-limb and a 60-cm BP-limb (n = 94). Results Preoperative median BMI was 44.1 (38–70), median age 35.5 (17–74) years, and 85 % of the patients were female. Follow-up rate after 5 years was 85 %. Eighteen months following surgery, the weight loss was significantly higher in the BP-limb group (p < 0.001), and this difference remained 7 years after surgery. Weight regain occurred in both groups, and 7 years after surgery, excess BMI loss (EBMIL) was 78.4 % in the BP-limb group compared to 67.1 % in the A-limb group (p < 0.001). Most patients (78 %) needed supplementation adjustment (iron, vitamin D and calcium) during the study period, significantly more often in the BP-limb group compared to the A-limb group (p < 0.001). Patients in the BP-limb group had more frequent stools than patients in the A-limb group; otherwise, gastro-intestinal symptoms rating scoring were comparable. Complication rate was similar. Conclusions Gastric bypass with a 2-m BP-limb gives better weight loss than gastric bypass with a 60-cm BP-limb and a 150-cm A-limb. Metabolic follow-up is of utmost importance, as most patients needed repeated adjustments of their supplementation.

Bowel length: measurement, predictors, and impact on bariatric and metabolic surgery. Surg Obes Relat Dis 2014; 11:328-34.

Abstract
BACKGROUND Small bowel length (SBL) determines the caloric absorptive capacity. The aim of this study was to evaluate SBL to identify patient-specific predictors and the interrelationships of SBL with anthropometric variables. METHODS Sex, age, and weight were recorded at the time of surgery when SBL and the estimated jejunal length (JLe) were measured by 3 different methods. RESULTS The mean SBL of 443 patients undergoing laparotomy (78% female) was 690±93.7 cm (range 350-1049 cm). Sex was correlated with SBL, as men had a longer small bowel than women (729±85 versus 678±92, P<.0001) and were significantly taller (173±8.2 versus 161±6.9, P<.001). Age did not correlate with SBL. The differences in length between fully stretched small bowel and nonstretched small bowel and between fully stretched small bowel and laparoscopic bowel were 137±19 cm and 32.4±11.4 cm, respectively. In a multivariate linear regression analysis model that included sex, age, height, and weight, only height was significantly correlated with SBL (P<.00001) and explained 12% of the variance in SBL. Sex, age, height, and JLe, but not SBL, were statistically highly significant in predicting 75% of the variance of body weight. CONCLUSIONS A positive association between height and SBL was found. Sex, age, height, and JLe may be strong predictors of weight. Individual JLe may be of importance in determining the weight loss and resolution of metabolic co-morbidities. Measuring the SBL can prevent the risk of nutritional consequences in malabsorptive, revisional, and metabolic procedures.

Abstract
The ideal length of the gastric bypass limbs is debated. Recent evidence suggests that standard limb lengths used today have a limited impact on patient weight loss. Our objective was to appraise critically the available evidence on the influence of the length of gastric bypass limbs on weight loss outcomes. We systematically reviewed MEDLINE, the Cochrane database of evidence-based reviews, and the Database of Abstracts of Reviews of Effects for articles reporting the effect of gastric bypass length on outcomes published between 1987 and 2009. Four randomized controlled trials and several retrospective studies were identified and reviewed. Longer Roux limb lengths (at least 150 cm) were associated with a very modest weight loss advantage in the short term in superobese patients. No significant impact of alimentary limb length on weight loss for patients with body mass index (BMI) <50 was seen. When the length of the common channel approaches 100 cm, a significant impact on weight loss is observed. The currently available literature supports the notion that a longer Roux limb (at least 150 cm) may be associated with a very modest weight loss advantage in the short term in superobese patients but has no significant impact on patients with BMI ≤50. To achieve weight loss benefit due to malabsorption, bariatric surgeons should focus on the length of the common channel rather than the alimentary or biliopancreatic limbs when constructing a gastric bypass especially in the superobese population where failure rates after conventional gastric bypass are higher.

Abstract
BACKGROUND Approximately one-third of U.S. adults are obese. Current evidence suggests that surgical therapies offer the morbidly obese the best hope for substantial and sustainable weight loss, with a resultant reduction in morbidity and mortality. Minimally invasive methods have altered the demand for bariatric procedures. However, no evidence-based clinical reviews yet exist to guide patients and surgeons in selecting the bariatric operation most applicable to a given situation. METHODS This evidenced-based review is presented in conjunction with a clinical practice guideline developed by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES). References were reviewed by the authors and graded as to the level of evidence. Recommendations were developed and qualified by the level of supporting evidence available at the time of the associated SAGES guideline publication. The guideline also was reviewed and co-endorsed by the American Society for Metabolic and Bariatric Surgery. RESULTS Bariatric surgery is the most effective treatment for severe obesity, producing durable weight loss, improvement of comorbid conditions, and longer life. Patient selection algorithms should favor individual risk-benefit considerations over traditional anthropometric and demographic limits. Bariatric care should be delivered within credentialed multidisciplinary systems. Roux-en-Y gastric bypass (RGB), adjustable gastric banding (AGB), and biliopancreatic diversion with duodenal switch (BPD + DS) are validated procedures that may be performed laparoscopically. Laparoscopic sleeve gastrectomy (LSG) also is a promising procedure. Comparative data find that procedures with more dramatic clinical benefits carry greater risks, and those offering greater safety and flexibility are associated with less reliable efficacy. CONCLUSIONS Laparoscopic RGB, AGB, BPD + DS, and primary LSG have been proved effective. Currently, the choice of operation should be driven by patient and surgeon preferences, as well as by considerations regarding the relative importance placed on discrete outcomes.

Abstract
BACKGROUND Laparoscopic gastric bypass, currently the most popular surgical method for bariatric therapy, have proved to be effective in weight loss, but some matters regarding its long-term efficacy for super-obese patients (BMI >50 kg/m2) have arisen. Biliopancreatic diversion (BPD) is a complex technique that has shown good results in the treatment of the super-obese patient. We analyze our >5 years results, evaluating weight loss, morbidity and mortality of this operation, depending on the length of the common and alimentary limbs. METHODS We studied two series of patients: 150 patients with BPD of Scopinaro (50-200 cm) and 70 patients with modified BPD (75-225 cm). The results have been analyzed in terms of weight loss, co-morbidity improvement, and postoperative morbidity using BAROS. RESULTS Range of follow-up is 1-12 years. Weight loss was slightly higher for the Scopinaro group than for the Modified group but with no significant difference. There was more prevalence of malnutrition and of iron deficiency in the Scopinaro group (16% and 60%) than in the modified group (2% and 40%), with similar postoperative morbidities. CONCLUSION The modified BPD method (75-225 cm) shows long-term effectiveness in weight loss and comorbidity improvement for super-obesity. Proteins, vitamins and oligoelement deficits appear distant in time, and thus it is necessary to maintain strict followup of these patients and supplement against deficiencies for the rest of their lives.

Abstract
BACKGROUND It is commonly believed that weight loss after biliopancreatic diversion/duodenal switch is inversely related to the length of the alimentary limb and the common channel. However, the effect of the biliopancreatic limb length (BPL) on weight loss has received little attention. METHODS A total of 1001 patients after biliopancreatic diversion/duodenal switch (209 men and 792 women, mean age 42 +/- 10 yr, mean body mass index [BMI] 52 +/- 9 kg/m(2)) were divided into 2 groups according to the ratio of the BPL to the total small bowel length (SBL): a BPL < or =45% of the SBL versus a BPL >45% of the SBL. The nutritional parameters and percentage of excess weight loss were compared between the 2 groups. RESULTS In patients with a BMI of < or =60 kg/m(2), the percentage of excess weight loss at 1 year postoperatively was 66.8% for those with a BPL < or =45% of the SBL and 69.3% for those with a BPL >45% of the SBL (P = NS). At 2 years, the corresponding percentages were 73.7% and 79.5% (P = NS) and, at 3 years, were 73.4% and 75.2% (P = NS). In patients with a BMI >60 kg/m(2), the corresponding percentages of excess weight loss was 56.8% versus 61.4% (P = .07) at 1 year, 62.2% versus 77.5% (P = .04) at 2 years, and 59.8% versus 77.5% at 3 years (P = .05). CONCLUSION The results of our study have shown that amount of weight lost after biliopancreatic diversion/duodenal switch is directly related to the proportion of small bowel bypassed in patients with a BMI >60 kg/m(2). Also, the effect increased with the duration of follow-up. In less heavy patients, the BPL/SBL ratio had a minimal effect on long-term weight loss and a more pronounced effect on nutritional parameters.

Abstract
Eating behavior is determined by a balance of memories in terms of reward and punishment to satisfy the urge to consume food. Refilling empty energy stores and hedonistic motivation are rewarding aspects of eating. Overfeeding, associated adverse GI effects, and obesity implicate punishment. In the current review, evidence is given for the hypothesis that bariatric surgery affects control over eating behavior. Moreover, any caloric overload will reduce the feeling of satiety. Durable weight loss after bariatric surgery is probably the result of a new equilibrium between reward and punishment, together with a better signaling of satiation due to beneficial metabolic changes. We propose to introduce three main treatment goals for bariatric surgery: 1) acceptable weight loss, 2) improvement of eating control, and 3) metabolic benefit. To achieve this goal, loss of 50% to 70% of excess weight will be appropriate (i.e. 30% to 40% loss of initial weight), depending on the degree of obesity prior to operation.

Abstract
The number of patients undergoing surgery for the treatment of obesity, and the proportion of the health care budget dedicated to this health problem, is growing exponentially. There are several competing surgical approaches for the management of morbid obesity. We review the literature relating to four of these: gastric bypass, biliopancreatic diversion, gastric banding, and gastric pacing. Our review finds that while enhancing the malabsorptive activity of these procedures may induce an incremental increase in excess body weight loss, the proportion of patients who fail to lose more than 50% of their excess body weight is similar no matter how radical is the surgery performed. There is little guidance from the literature as to appropriate patient selection for the varying procedures, and anonymously reported registries have yet to show that patients who undergo bariatric surgery have enhanced longevity. To date, the bariatric surgical community has not conducted adequately powered randomized prospective trials to elucidate key elements of the surgical procedure such as optimal bypass length, to determine whether mixed operations are superior to those that offer intake restriction only, and to define what constitutes success after bariatric surgery. As a public health measure, bariatric surgery in the United States is being pursued in an irrational manner, being concentrated in areas where there are fewer morbidly obese patients, and used disproportionately among the population of white obese females.
