Abstract
Our study aimed to evaluate the usefulness of indocyanine green (ICG) angiography during conversional or revisional bariatric surgery. We prospectively enrolled all patients scheduled for reoperative bariatric surgery with gastric pouch resizing and ICG assessment and we compared them with a retrospective series of similar patients who did not receive ICG. The primary outcome was the rate of intraoperative change in the surgical strategy due to the ICG test. We included 32 prospective patients receiving intraoperatively an ICG perfusion test and 48 propensity score-matched controls. The mean age was 50.7 ± 9.7 years, 67 (83.7%) patients were female, and the mean BMI was 36.8 ± 5.3 kg/m2. The patient characteristics were similar in both groups. The ICG angiography was successfully conducted in all patients, and no change of the surgical strategy was necessary. Postoperative complications were similar in both groups (6.2% vs. 8.3%, p = 0.846), as well as operative time (125 ± 43 vs. 133 ± 47 min, p = 0.454) and length of hospital stay (2.8 ± 1.0 vs. 3.3 ± 2.2 days, p = 0.213). Our study suggested that ICG fluorescence angiography might not have been useful for assessing the blood supply of the gastric pouch in patients who underwent reoperative bariatric surgery. Therefore, it remains uncertain whether the application of this technique is indicated.

Abstract
BACKGROUND Venous thromboembolism (VTE), which comprises deep vein thrombosis (DVT) and pulmonary embolism (PE), is the leading cause of preventable death in hospitalised people and the third most common cause of mortality in surgical patients. People undergoing bariatric surgery have the additional risk factor of being overweight. Although VTE prophylaxis in surgical patients is well established, the best way to prevent VTE in those undergoing bariatric surgery is less clear. OBJECTIVES To evaluate the benefits and harms of pharmacological interventions (alone or in combination) on venous thromboembolism and other health outcomes in people undergoing bariatric surgery compared to the same pharmacological intervention administered at a different dose or frequency, the same pharmacological intervention or started at a different time point, another pharmacological intervention, no intervention or placebo. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 1 November 2021. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs in males and females of any age undergoing bariatric surgery comparing pharmacological interventions for VTE (alone or in combination) with the same pharmacological intervention administered at a different dose or frequency, the same pharmacological intervention started at a different time point, a different pharmacological intervention, no treatment or placebo. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were 1. VTE and 2. major bleeding. Our secondary outcomes were 1. all-cause mortality, 2. VTE-related mortality, 3. PE, 4. DVT, 5. adverse effects and 6. quality of life. We used GRADE to assess certainty of evidence for each outcome. MAIN RESULTS We included seven RCTs with 1045 participants. Data for meta-analysis were available from all participants. Four RCTs (597 participants) compared higher-dose heparin to standard-dose heparin: one of these studies (139 participants) used unfractionated heparin (UFH) and the other three (458 participants) used low-molecular-weight heparin (LMWH). One study compared heparin versus pentasaccharide (198 participants), and one study compared starting heparin before versus after bariatric surgery (100 participants). One study (150 participants) compared combined mechanical and pharmacological (enoxaparin) prophylaxis versus mechanical prophylaxis alone. The duration of the interventions ranged from seven to 15 days, and follow-up ranged from 10 to 180 days. Higher-dose heparin versus standard-dose heparin Compared to standard-dose heparin, higher-dose heparin may result in little or no difference in the risk of VTE (RR 0.55, 95% CI 0.05 to 5.99; 4 studies, 597 participants) or major bleeding (RR 1.19, 95% CI 0.48 to 2.96; I2 = 8%; 4 studies, 597 participants; low-certainty) in people undergoing bariatric surgery. The evidence on all-cause mortality, VTE-related mortality, PE, DVT and adverse events (thrombocytopenia) is uncertain (effect not estimable or very low-certainty evidence). Heparin versus pentasaccharide Heparin compared to a pentasaccharide after bariatric surgery may result in little or no difference in the risk of VTE (RR 0.83, 95% CI 0.19 to 3.61; 1 study, 175 participants) or DVT (RR 0.83, 95% CI 0.19 to 3.61; 1 study, 175 participants). The evidence on major bleeding, PE and mortality is uncertain (effect not estimable or very low-certainty evidence). Heparin started before versus after the surgical procedure Starting prophylaxis with heparin 12 hours before surgery versus after surgery may result in little or no difference in the risk of VTE (RR 0.11, 95% CI 0.01 to 2.01; 1 study, 100 participants) or DVT (RR 0.11, 95% CI 0.01 to 2.01; 1 study, 100 participants). The evidence on major bleeding, all-cause mortality and VTE-related mortality is uncertain (effect not estimable or very low-certainty evidence). We were unable to assess the effect of this intervention on PE or adverse effects, as the study did not measure these outcomes. Combined mechanical and pharmacological prophylaxis versus mechanical prophylaxis alone Combining mechanical and pharmacological prophylaxis (started 12 hours before surgery) may reduce VTE events in people undergoing bariatric surgery compared to mechanical prophylaxis alone (RR 0.05, 95% CI 0.00 to 0.89; number needed to treat for an additional beneficial outcome (NNTB) = 9; 1 study, 150 participants; low-certainty). We were unable to assess the effect of this intervention on major bleeding or morality (effect not estimable), or on PE or adverse events (not measured). No studies measured quality of life. AUTHORS' CONCLUSIONS Higher-dose heparin may make little or no difference to venous thromboembolism or major bleeding in people undergoing bariatric surgery when compared to standard-dose heparin. Heparin may make little or no difference to venous thromboembolism in people undergoing bariatric surgery when compared to pentasaccharide. There are inadequate data to draw conclusions about the effects of heparin compared to pentasaccharide on major bleeding. Starting prophylaxis with heparin 12 hours before bariatric surgery may make little or no difference to venous thromboembolism in people undergoing bariatric surgery when compared to starting heparin after bariatric surgery. There are inadequate data to draw conclusions about the effects of heparin started before versus after surgery on major bleeding. Combining mechanical and pharmacological prophylaxis (started 12 hours before surgery) may reduce VTE events in people undergoing bariatric surgery when compared to mechanical prophylaxis alone. No data are available relating to major bleeding. The certainty of the evidence is limited by small sample sizes, few or no events, and risk of bias concerns. Future trials must be sufficiently large to enable analysis of relevant clinical outcomes, and should standardise the time of treatment and follow-up. They should also address the effect of direct oral anticoagulants and antiplatelets, preferably grouping them according to the type of intervention.

Abstract
BACKGROUND Despite thromboprophylaxis, postoperative deep vein thrombosis and pulmonary embolism occur after bariatric surgery, perhaps because of failure to achieve optimal prophylactic levels in the obese population. OBJECTIVES The aim of this study was to evaluate the adequacy of prophylactic dosing of enoxaparin in patients with severe obesity by performing an antifactor Xa (AFXa) assay. SETTING An academic medical center METHODS: In this observational study, all bariatric surgery cases at an academic center between December 2016 and April 2017 who empirically received prophylactic enoxaparin (adjusted by body mass index [BMI] threshold of 50 kg/m2) were studied. The AFXa was measured 3-5 hours after the second dose of enoxaparin. RESULTS A total of 105 patients were included; 85% were female with a median age of 47 years. In total, 16 patients (15.2%) had AFXa levels outside the prophylactic range: 4 (3.8%) cases were in the subprophylactic and 12 (11.4%) cases were in the supraprophylactic range. Seventy patients had a BMI <50 kg/m2 and empirically received enoxaparin 40 mg every 12 hours; AFXa was subprophylactic in 4 (5.7%) and supraprophylactic in 6 (8.6%) of these patients. Of the 35 patients with a BMI ≥50 who empirically received enoxaparin 60 mg q12h, no AFXa was subprophylactic and 6 (17.1%) were supraprophylactic. Five patients (4.8%) had major bleeding complications. One patient developed pulmonary embolism on postoperative day 35. CONCLUSION BMI-based thromboprophylactic dosing of enoxaparin after bariatric surgery could be suboptimal in 15% of patients with obesity. Overdosing of prophylactic enoxaparin can occur more commonly than underdosing. AFXa testing can be a practical way to measure adequacy of pharmacologic thromboprophylaxis, especially in patients who are at higher risk for venous thromboembolism or bleeding.

Abstract
Objective Intragastric balloon (IGB) therapy is a low-invasion treatment for obesity. Recently, a low-carbohydrate diet has shown effectiveness for encouraging weight loss, but whether or not a low-carbohydrate diet improves the efficacy of IGB therapy remains unclear. Therefore, we examined the effectiveness of a low-carbohydrate diet compared with a calorie-restricted diet in combination with IGB therapy. Methods A prospective study was conducted on 51 patients who had undergone IGB therapy from October 2012 to December 2017. Overall, 31 of the 51 patients were included in this study (12-month assessment after IGB placement). These 31 cases consisted of 18 IGB plus low-carbohydrate diet and 13 IGB plus calorie-restricted diet. We compared the two groups with respect to body weight loss as outcomes. Results At 12 months after IGB placement, the body weight was significantly lower than that observed at baseline in both the IGB plus low-carbohydrate diet group (baseline 101.9±25.8 kg, 12 months 88.2±21.9 kg) (p<0.0001) and the IGB plus calorie-restricted diet group (baseline 103.5±17.0 kg, 12 months 89.1±6.2 kg) (p<0.005). The percentage of excess weight loss in the IGB plus low-carbohydrate diet group was slightly higher than that in the IGB plus calorie-restricted diet group, but there was no significant difference between the 2 groups at 12 months after IGB placement (IGB plus low-carbohydrate 49.9±60.0%, IGB plus calorie-restricted diet 33.1±27.0%). Conclusion Our study demonstrated that both a low-carbohydrate diet and a calorie-restricted diet were effective interventions for weight reduction in combination with IGB therapy.

Abstract
INTRODUCTION Prior meta-analysis has reported mortality rates among post-operative bariatric patients, but they have not considered psychiatric factors like suicide contributing to mortality. OBJECTIVES The current meta-analysis aims to determine the pooled prevalence for mortality and suicide amongst cohorts using reported suicides post bariatric surgery. It is also the aim of the current meta-analytical study to determine moderators that could account for the heterogeneity found. RESULTS In our study, the pooled prevalence of mortality in the studies which reported suicidal mortality was 1.8% and the prevalence of suicide was 0.3%. Mean body mass index (BMI) and the duration of follow-up appear to be significant moderators. CONCLUSIONS Given the prevalence of suicide post bariatric surgery, it is highly important for bariatric teams to consider both the medical and psychiatric well-being of individuals pre- and post-operatively.

Abstract
BACKGROUND Although the incidence of leaks after Roux-en-Y gastric bypass (RYGB) significantly decreased over time, their detection still remains challenging. OBJECTIVE This study aimed to determine the usefulness of drain amylase levels to detect leaks after RYGB. METHODS This is a population-based study which enrolled 170 individuals who underwent RYGB. Drain amylase levels were determined on the first and fourth postoperative days. Two thresholds were evaluated: three times higher than the serum levels (parameter I) and higher than 250 IU/L (parameter II). The main outcomes evaluated were perioperative morbidity, the occurrence of leaks, 30-day readmissions and reoperations, hospital stay, and mortality. RESULTS Considering the parameter I, high drain amylase levels were significantly associated with leaks (12.5% vs 0; P<0.00001). Considering the parameter II, high drain amylase levels were significantly associated with longer hospital stay (8±5.7 vs 4.5±1.3 days; P=0.00032), 30-day reoperations (50% vs 3%; P=0.000285), and leaks (50% vs 0; P<0.00001). The parameter I presented a sensitivity of 100% and specificity of 95.9%, whereas the parameter II presented a sensitivity of 100% and a specificity of 99.4%. CONCLUSION The determination of drain amylase levels after RYGB was a significant indicator of leaks, hospital stay, and 30-day reoperations. This finding reinforces the importance of abdominal drainage in the RYGB within this context.

Abstract
PURPOSE A concern regarding the safety of bariatric surgery may explain the fact that only a minor fraction of morbidly obese patients has access to it. This is a population-based, nationwide study reporting 30-day, 90-day, and 1-year mortality rates following bariatric surgery in comparison with mortality rates after other common operations in Finland. MATERIALS AND METHODS Patients undergoing surgery between January 2009 and December 2013 were included. Data on surgical procedures were obtained from the national hospital discharge registry, and cause of death was obtained from Statistics Finland. RESULTS Inclusion criteria were met by 156,536 patients. Of these, 3918 underwent surgery for morbid obesity. Three patients (0.08%) died within 30 days following bariatric surgery. The 30-day mortality rate was lower only following prostatectomy. Compared with bariatric surgery, the hazard ratios (HR) for 1-year postoperative mortality were significantly higher for elective cholecystectomy (HR 2.38, 95% CI 1.39-4.08, p = 0.002), hysterectomy (HR 2.87, 95% CI 1.68-4.92, p < 0.001), knee arthroplasty (HR 2.23, 95% CI 1.31-3.81, p = 0.003), hip arthroplasty (HR 11.7, 95% CI 6.90-19.8, p < 0.001), colorectal resections (HR 27.5, 95% CI 16.2-46, p < 0.001), gastric resection (HR 53.0, 95% CI 30.2-93.2, p < 0.001), gastrectomy (HR 74.7, 95% CI 43.0-130, p < 0.001), and coronary artery bypass grafting (HR 30.7, 95% CI 17.4-54.3, p < 0.001). CONCLUSION Mortality rates following bariatric surgery are low and similar or lower than mortality rates following all other common elective surgeries.

Abstract
Background Obesity is an increasing worldwide problem associated with a vast number of comorbidities. Decreasing body weight by only 5-10% has been shown to slow and even prevent the onset of obesity-related comorbidities. Between pharmacological therapy and bariatric surgery a great variety of endoscopic techniques are available, the most common being intragastric balloon (IGB). The purpose of this study was to assess the safety, tolerance, and kinetics of IGBs in weight loss. The kinetics of weight loss were evaluated in 2 different contexts and phases: after the IGB's removal and after follow-up that varied between 6 and 12 months. Successful weight loss was defined as ≥10% weight loss after 6-12 months. Methods The study included 51 patients who had undergone Orbera® IGB placement between September 2014 and February 2016. Inclusion criteria were age between 18 and 65 years; body mass index (BMI) 28-35 with severe obesity-related disorders; or BMI 35-40. The IGB was removed 6 months later. All patients were followed for a minimum period of 6-12 months. Results Of 51 patients, 16 were excluded (7 due to intolerance) and 35 patients entered the study, of which 83% were followed for more than 6-12 months. The average weight loss (WL) and % excess WL (%EWL) after 6 months of treatment were 11.94 kg and 42.16%, respectively. At 6-12 months, after removal of the IGB, the mean WL was 8.25 kg and %EWL was 30.27%. Nineteen patients attained a WL of ≥10% the baseline value at IGB removal and 12 maintained their weight below this threshold during the 6-12 following months. Conclusions After temporary IGB implantation in overweight or obese individuals, a WL that was ≥10% of weight at baseline was achieved in 54.3% and sustained at 6-12 months in 41.4% of participants. IGBs are an attractive intermediate option between diet and exercise programs and bariatric surgery. In general, IGB placement is a safe and well-tolerated procedure.

Abstract
Morbid obesity has become a very common problem worldwide, causing severe
health-related consequences including cardiovascular or metabolic diseases,
arthritis, sleep apnea, or an increased risk of cancer. Bariatric surgery was
shown to be the only way to achieve sustainable weight loss and to decrease the
frequency and severity of metabolic and cardiovascular comorbidities. The
purpose of this article is to present a case of bariatric surgery complicated
with lesion of the aorta with a lethal outcome.

Abstract
PURPOSE The perioperative management of bariatric surgery patients is described. SUMMARY Obesity and anatomical changes create unique challenges for clinicians when caring for bariatric surgery patients. Common bariatric surgery procedures performed include Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric banding. Pain management in the acute postoperative period depends on careful dosing of opioid agents and the use of adjunctive agents. Prevention and management of infectious complications include appropriate surgical prophylaxis, monitoring and rapid treatment of suspected intra-abdominal infections, and detection and treatment of Helicobacter pylori infection. Venous thromboembolism (VTE) prophylaxis and treatment are complicated by obesity, and the use of pharmacologic agents must be balanced with bleeding risk. Bleeding is a serious complication that should be closely monitored in the immediate postoperative period. Blood products remain first-line therapy for the treatment of bleeding in this population. Acute differences in drug absorption as well as emerging hormonal changes necessitate the immediate postoperative adjustment of chronic medications to ensure both safety and efficacy. Pharmacists are valuable members of interprofessional teams for bariatric surgery patients because they provide expertise on the availability of dosage forms and dosage modification to ensure that patient pharmacotherapy is not interrupted; assist in the management of hypertension, diabetes, and psychotropic medications; and ensure appropriate antimicrobial prophylaxis and VTE prophylaxis and treatment dosages. CONCLUSION The management of patients in the perioperative period of bariatric surgery requires appropriate selection and dosing of medications for pain management and treatment of infectious complications, VTE, bleeding, and other chronic diseases.

Abstract
Postoperative peritonitis (POP) is a common surgical complication after bariatric surgery (BS). We assessed the importance of positive fungal cultures in these cases of POP admitted to the intensive care unit. Clinical features and outcome were compared in 25 (41%) Candida-positive patients (6 (22%) fluconazole-resistant Candida glabrata) and 36 patients without Candida infection. Candida infections were more commonly isolated in late-onset peritonitis and were often associated with multidrug-resistant bacteria. Risk factors for intensive care unit mortality (19.6%) were diabetes and superobesity. Candida infections, including fluconazole-resistant strains, are common in POP after BS. These data encourage the empirical use of a broad-spectrum antifungal agent.

Abstract
The aim of this retrospective study was to examine the anastomotic erosion due to drain and success of fibrin sealant in its management. Between 2013 and 2014, 102 patients underwent LRYGB and gastrojejunal anastomotic leak occurred due to drain erosion in 2 of them. The diagnosis was established with saliva drainage and was confirmed by upper gastrointestinal series. The absence of hemodynamic instability was directed us to conservative treatment. During the endoscopy, dehiscence was assessed and fibrin sealant was applied. The leaks healed progressively in a few days, and the drains removed within 6 days. Seven and 9 days later, the patients were discharged without any problem. Anastomotic leaks after bariatric surgery can cause severe morbidity, cost, and effects quality of life. Hemodynamically stable and drained patients are candidates for conservative methods. Endoscopic injection of fibrin sealant has been successful in closing gastric leaks.

Abstract
Severe obesity is associated with increased morbidity and mortality and represents a major health care problem with increasing incidence worldwide. Bariatric surgery, through its efficacy and improved safety, is emerging as an important available treatment for patients with severe obesity. Classically, bariatric surgery has been described as either a restrictive or a hybrid surgery, which is a combination of restriction and malabsorption. For most severely obese patients, bariatric surgery results in the remission of major obesity-related comorbidities including type 2 diabetes mellitus, sleep apnea, hypertension, and dyslipidemia. Thus, bariatric surgery reduces cardiovascular risk burden, and overall mortality risk. Early complications (< 30 days) after bariatric surgery were reported to be < 10% and tend to be lower in restrictive surgeries compared with hybrid surgeries. Most common early complications reported are gastric and anastomosis leak (1.6%-5.1%), bleeding (0.5%-3.5%), and pulmonary embolism (0.2%-1%). Long-term complications (> 30 days) might differ depending on the type of bariatric surgery. According to the type of surgery and the type of study, the 30-day operative mortality rates differ from 0.1% to 1.2%. Studies on postoperative outcomes, investigations on weight loss physiology, and mechanism of action after bariatric surgery provide a better understanding of the bariatric surgery metabolic benefits. In this article, we present an overview of bariatric procedures with their effects, including risks and benefits, on the severely obese patients' health. It provides evidence to support surgical treatment of severe obesity to achieve cardiovascular disease risk reduction in severely obese patients.

Abstract
BACKGROUND The Bioenterics Intragastric Balloon (BIB) is effective for weight loss. However, comparisons of its effectiveness between groups with different body mass index (BMI) are rare. This study compared the effectiveness of BIB treatment in patients with BMI <32 kg/m(2) and those with BMI ≥ 32 kg/m(2) at the time of BIB removal and at 1 year later. METHODS Between April 2009 and June 2011, 28 obese patients who completed a full course of BIB treatment were enrolled. There are 16 patients with BMI <32 and 12 with BMI ≥ 32. Patients who lost more than 20 % of excess weight (% EWL) were categorized as responders. RESULTS The BMI significantly fell from 32.4 ± 3.7 to 28.5 ± 3.7 kg/m(2) (P < 0.01) at the time of BIB removal. All biochemical measurements except for cholesterol level were significantly improved. The median value of %EWL of all patients at BIB removal was 40.1, and 20 patients (71.4 %) were responders. Adherence to dietitian counseling was significantly better in responders than in non-responders (85 vs. 25 %, respectively; P < 0.01). The percentage of responders at 1 year after BIB removal was significantly higher among patients with BMI <32 than those with ≥ 32 (62.5 vs. 16.7 %, respectively; P = 0.02). CONCLUSIONS BIB placement can achieve significant weight loss and improvement of co-morbidities in obese patients. Better adherence to dietitian counseling is associated with better response. Patients with BMI <32 maintain better weight loss at 1 year after BIB removal.

Abstract
Background Anastomotic leak is one of the most serious complications following bariatric laparoscopic Roux-en-Y gastric bypass (LRYGB), and associated with high morbidity rates and prolonged hospital stay. Timely management is of utmost importance for the clinical outcome. This study evaluated the approach to suspected leakage in a high-volume bariatric surgery unit. Methods All consecutive patients who underwent LRYGB performed by the same team of surgeons were registered prospectively in a clinical database from September 2005 to June 2012. Suspected leaks were identified based on either clinical suspicion and/or associated laboratory values, or by a complication severity grade of at least II using the Clavien–Dindo score. Results A total of 6030 patients underwent LRYGB during the study period. The leakage rate was 1·1 per cent (64 patients). Forty-five leaks (70 per cent) were treated surgically and 19 (30 per cent) conservatively. Eight (13 per cent) of 64 patients needed intensive care and the mortality rate was 3 per cent (2 of 64). Early leaks (developing in 5 days or fewer after LRYGB) were treated by suture of the defect in 20 of 22 patients and/or operative drainage in 13. Late leaks (after 5 days) were managed with operative drainage in 19 of 23 patients and insertion of a gastrostomy tube in 15. Patients who underwent surgical treatment early after the symptoms of leakage developed had a shorter hospital stay than those who had symptoms for more than 24 h before reoperation (12·5 versus 24·4 days respectively; P < 0·001). Conclusion Clinical suspicion of an anastomotic leak should prompt an aggressive surgical approach without undue delay. Early operative treatment was associated with shorter hospital stay. Delays in treatment, including patient delay, after symptom development were associated with adverse outcomes.

Abstract
Bariatric surgery is one of the most effective treatments for morbid obesity, and a large body of research indicates significant long-term weight loss. While overall mortality decreases in patients who received bariatric surgery, a number of studies have shown that suicide rates are higher in bariatric patients than in control groups. The objective of this study was to present a systematic review of suicide mortality after bariatric surgery and calculate an estimate for the suicide rate. Literature researches of the databases PubMed, Web of Knowledge, PsychInfo, ScienceDirect and Google Scholar were conducted. Thirty studies concerning bariatric surgery and completed suicides met the inclusion criteria. We included 28 studies in the estimation of a suicide rate for the bariatric population. Only one study (Tindle et al.) put a main focus on suicide after bariatric surgery; this was therefore chosen as an adequate reference figure for comparison. The other 27 chosen studies were compared with World Health Organization data and the suicide rate reported by Tindle et al. Twenty-three thousand eight hundred eighty-five people were included in the analysis. In the literature, we found a total of 95 suicides when examining 190,000 person-years of post-bariatric surgery data. Little information was provided describing the reasons for suicide and the time-point of these events after surgery. We estimated a suicide rate of 4.1/10,000 person-years (95% confidence interval [3.2, 5.1]/10,000 person-years). A comparison with Tindle et al. demonstrates that their rate is significantly higher than our estimate (P = 0.03). Bariatric surgery patients show higher suicide rates than the general population. Therefore, there is a great need to identify persons at risk and post-operative psychological monitoring is recommended.

Abstract
OBJECTIVE There is a growing research literature suggesting that there may be elevated risk of suicide following bariatric surgery. Most of the data reported thus far has been cross-sectional and observational, and very little is known about the possible specific causal variables involved. DESIGN AND METHODS The purpose of this report is to review this literature and to review possible risk factors for increased suicidal risk following bariatric surgery, to delineate future research directions. RESULTS First a variety of medical, biological, and genetic factors, including the persistence or recurrence of medical comorbidities after bariatric surgery, the disinhibition and impulsivity secondary to changes in the absorption of alcohol, hypoglycemia, as well as pharmacokinetic changes that may affect the absorption of various medications including antidepressant medications are reviewed. Also reviewed are possible mediating factors involving changes in various peptidergic systems such as GLP-1 and Ghrelin. A number of psychosocial issues that might be involved are discussed, including lack of improvement in quality of life after surgery, continued or recurrent physical mobility restrictions, persistence or recurrence of sexual dysfunction and relationship problems, low self-esteem, and a history of child maltreatment. Inadequate weight loss or weight regain are also discussed. CONCLUSIONS A number of possible contributing factors have been identified. Possible theoretical models involved and directions for research are suggested.

Abstract
Bariatric surgery is gaining in popularity in the United States and around the world as a treatment for morbid obesity. Patients seek surgery in order to lose weight and limit the long-term effects of insulin-resistant diabetes, heart disease and lung disease, including risk of sudden death. While gastric bypass in patients with morbid obesity can reduce the risk of diabetes and myocardial infarction to population levels, the risk of death remains increased. These patients may die suddenly and unexpectedly as a direct result of surgery, as an indirect result of surgery, or of end-organ damage wrought by years of obesity, completely unrelated to the surgery. Proper forensic pathologic assessment of these patients requires an understanding of the anatomic changes caused by bariatric surgery, the complications and the metabolic consequences of the different procedures. In order to better understand this subgroup of patients, a search of the peer-reviewed medical literature at the National Library of Medicine was conducted for articles using the keywords bariatric, surgery, gastric bypass, autopsy, review, toxicology, alcohol, drug, ethanol, absorption, elimination, litigation, forensic, and death. This review outlines the most common laparoscopic and open surgical procedures; the common immediate post-surgical complications that lead to morbidity and mortality; forensic toxicological considerations in bariatric patients; and the long-term complications and other causes that could lead to unexpected death in these patients.

Abstract
BACKGROUND Mortality following bariatric surgery is a rare event in contemporary series, making it difficult for any single center to draw meaningful conclusions as to cause of death. Nevertheless, much of the published mortality data come from single-center case series and reviews of administrative databases. These sources tend to produce lower mortality estimates than those obtained from controlled clinical trials. Furthermore, information about the causes of death and how they were determined is not always available. The aim of the present report is to describe in detail all deaths occurring within 30 days of surgery in the Longitudinal Assessment of Bariatric Surgery (LABS). METHODS LABS is a ten-center observational cohort study of bariatric surgical outcomes. Data were collected prospectively for bariatric surgeries performed between March 2005 and April 2009. All deaths occurring within 30-days of surgery were identified, and cause of death assigned by an independent Adjudication Subcommittee, blinded to operating surgeon and site. RESULTS Six thousand one hundred eighteen patients underwent primary bariatric surgery. Eighteen deaths (0.3%) occurred within 30-days of surgery. The most common cause of death was sepsis (33% of deaths), followed by cardiac causes (28%), and pulmonary embolism (17%). For one patient cause of death could not be determined despite examination of all available information. CONCLUSIONS This study confirms the low 30-day mortality rate following bariatric surgery. The recognized complications of anastomotic leak, cardiac events, and pulmonary emboli accounted for the majority of 30-day deaths.

Abstract
BACKGROUND The intragastric balloon is a widely used method in the treatment of obesity indicated for those patients who have failed to achieve and maintain the weight loss with conventional measures or for preparation of patients who are candidates for bariatric surgery. METHODS From April 2007 to April 2009, 171 consecutive patients (111 females, 60 males; mean age 39.2 ± 10.5, mean weight 123.2 ± 27.1 kg) were evaluated before and 6 months after bioenteric intragastric balloon (BIB) placement by assessment of anthropometric and biochemical parameters. RESULTS The mean BMI during balloon treatment declined from 41.9 ± 7.3 to 36.0 ± 7.9 kg/m² (p < 0.001) with a percentage of excess weight loss of 39.7 ± 23.6 and percentage of excess body mass index loss of 39.5 ± 25.1. A significant improvement in blood pressure, glycemia, and triglyceride level but not in total cholesterol, high-density lipoprotein, and low-density lipoprotein cholesterol levels was seen. CONCLUSION Results of this large prospective single center study confirmed that intragastric balloon is useful and safe method for promoting weight loss. Due to improvement of metabolic parameters, treatment with BIB results in reduction of cardiovascular risk and provides a sustained benefit on liver function in obese patients.

Abstract
PURPOSE Bariatric surgery is recognized as the treatment of choice for class III obesity (body mass index ≥40) and has been increasingly recommended for obese patients. Prior research has suggested an excess of deaths due to suicide following bariatric surgery, but few large long-term follow-up studies exist. We examined postbariatric surgery suicides by time since operation, sex, age, and suicide death rates as compared with US suicide rates. METHODS Medical data following bariatric operations performed on Pennsylvania residents between January 1, 1995 and December 31, 2004 were obtained from the Pennsylvania Health Care Cost and Containment Council. Matching mortality data from suicides between September 1, 1996 and December 28, 2006 were obtained from the Division of Vital Records, Pennsylvania State Department of Health. RESULTS There were 31 suicides (16,683 operations), for an overall rate of 6.6/10,000; 13.7 per 10,000 among men and 5.2 per 10,000 among women. About 30% of suicides occurred within the first 2 years following surgery, with almost 70% occurring within 3 years. For every age category except the youngest, suicide rates were higher among men than women. Age- and sex-matched suicide rates in the US population (ages 35-64 years) were 2.4/10,000 (men) and 0.7/10,000 (women). CONCLUSIONS Compared with age and sex-matched suicide rates in the US, there was a substantial excess of suicides among all patients who had bariatric surgery in Pennsylvania during a 10-year period. These data document a need to develop more comprehensive longer-term surveillance and follow-up methods in order to evaluate factors associated with postbariatric surgery suicide.

Abstract
Bariatric surgery for obesity has emerged as an effective and commonly used treatment modality. This paper reviews the surgical site infections (SSIs) that occur post bariatric surgery and SSI prevention. The benefit of bariatric surgery resulting in profound weight loss brings with it consequences in the form of postoperative complications that can have profound effects on morbidity and mortality in these patients. This paper sets out to define different types of SSIs that occur following bariatric surgery and to discuss existing literature on the critical aspects of SSI prevention and the appropriate use of surgical antimicrobial prophylaxis for bariatric surgery.

Abstract
BACKGROUND Obesity is a major risk factor for the development of type 2 diabetes mellitus (T2DM). Surgery is the most effective treatment for morbid obesity, and it has been shown to lead to dramatic improvement in type T2DM. However, data concerning obese Asian patients have not been reported, and the mechanism of improving T2DM after bariatric surgery in this population remains speculative. METHODS From April 1997 to March 2006, 1,375 patients undergoing obesity surgery were recruited for our study of the effects of weight loss surgery on type 2 diabetes mellitus (T2DM). Laparoscopic vertical banded gastric partition (LVBG) was performed in 552 patients (40.1%), laparoscopic gastric bypass in 660 patients (48.0%), and laparoscopic adjustable gastric banding (LAGB) in 140 patients (10.2%). Another 23 patients (1.7%) received open or revision surgery. We evaluated the clinical data and effect of obesity surgery on T2DM, impaired fasting glucose (IFG) and compared the changes with those with normal fasting glucose. RESULTS Among all the patients, 166 (12.1%) had impaired fasting glucose (IFG) and 247 (18.0%) had T2DM. Patients with IFG or DM were significantly older, more central obese, and they had higher insulin resistance and a higher HbA1C level than those with normal fasting glucose. The mean total weight loss for the population was 28.6%, 29.1%, 28.5%, 23.8%, and 24.4% (at 1, 2, 3, 5, and 7 years after surgery). There was no increase of surgical risk in T2DM or IFG patients. One year after operation, fasting plasma glucose returned to normal in 78.5% of T2DM patients and 94.7% of IFG patients. The HbA1C level returned to under 7.0 in 81.5% of T2DM and in 100% of IFG patients. Laparoscopic gastric bypass patients had a greater weight loss and a higher rate of glucose normalization (93.1%) than the LVBG patients (85.3%) and LAGB patients (73.9%), but no difference in HbA1C normalization. CONCLUSIONS Obesity surgery resulted in significant and sustained weight loss with a cure rate of T2DM up to 80% in morbidly obese Asian patients. Gastric bypass surgery had a better result in T2DM cure rate than LVBG and LAGB because of better weight reduction.

Abstract
BACKGROUND Postoperative mortality is a rare event after bariatric surgery. The main goal of this study was to calculate the 30-day mortality rate postbariatric "open" surgery and the length of hospital stay of patients assisted by a health maintenance organization in Brazil. We also investigate their association with sex, age, BMI, preexisting comorbidities, and volume of procedures performed by surgeons. METHODS A total of 2,167 patients who underwent RYGB between 01/2004 and 12/2007 were analyzed. The deaths and hospital stay were identified in the healthcare transactional database and the morbidity data in the preoperative medical audit records. Factors contributing to adverse outcomes were determined by multiple logistic regression analysis. RESULTS The overall mortality rate was 0.64%, with a decreasing trend over the years. The median hospital stay was 3.1 days. In the multivariate analysis, both mortality and longer hospital stay were positively and significantly associated with age > 50 years, BMI > 50 kg/m(2), and surgeon volume of less than 20 bariatric surgeries/year. Presence of hypertension also increased the risk of longer hospital stay. Multivariate analysis showed that the 30-day mortality was six times higher in patients operated by professionals who performed less surgeries/year and longer hospital stay, four times more frequent. CONCLUSIONS The 30-day mortality post-RYGB is similar to the rates found in developed countries and much lower than the rates found for patients assisted by the public health system in Brazil. In addition to age and clinical factors, the results suggest that mortality and longer hospital stay are strong and inversely related to surgeon's experience.

Abstract
BACKGROUND Laparoscopic gastric bypass resulted in significant weight loss and resolution of type 2 diabetes mellitus (T2DM). The current indication for bariatric surgery is mainly applied for patients with body mass index (BMI)>35 kg/m2 with comorbidity status. However, little is known concerning T2DM patients with BMI<35 kg/m2. Recent studies have suggested that T2DM patients with BMI<35 kg/m2 might benefit from gastric bypass surgery. METHODS From Jan 2002 to Dec 2006, 820 patients who underwent laparoscopic mini-gastric bypass were enrolled in a surgically supervised weight loss program. We identified 201 (24.5%) patients who had impaired fasting glucose or T2DM. All the clinical data were prospectively collected and stored. Patients with BMI<35 kg/m2 were compared with those of BMI>35 kg/m2. Successful treatment of T2DM was defined by HbA1C<7.0%, LDL<100 mg/dl, and triglyceride<150 mg/dl. RESULTS Among the 201 patients, 44 (21.9%) had BMI<35 kg/m2, and 114 (56.7%) had BMI between 35 and 45, 43 (21.4%) had BMI>45 kg/m2. Patients with BMI<35 kg/m2 are significantly older, female predominant, had lower liver enzyme and C-peptide levels than those with BMI>35 kg/m2. The mean total weight loss for the population was 32.1, 33.4, 31.9, and 32.8% (at 1, 2, 3, 5 years after surgery), and percentage to change in BMI was 31.9, 34.2, 32.2, and 29.5% at 1, 2, 3, and 5 years. One year after surgery, fasting plasma glucose returned to normal in 89.5% of BMI<35 kg/m2 T2DM and 98.5% of BMI>35 kg/m2 patients (p=0.087). The treatment goal of T2DM (HbA1C<7.0%, LDL<150 mg/dl and triglyceride<150 mg/dl) was met in 76.5% of BMI<35 kg/m2 and 92.4% of BMI>350 kg/m2 (p=0.059). CONCLUSION Laparoscopic gastric bypass resulted in significant and sustained weight loss with successful treatment of T2DM up to 87.1%. Despite a slightly lower response rate of T2DM treatment, patients with BMI <35 still had an acceptable DM resolution, and this treatment option can be offered to this group of patients.

Abstract
OBJECTIVE To define mortality rates and risk factors of different bariatric procedures and to identify strategies to reduce the surgical risk in patients undergoing bariatric surgery. SUMMARY BACKGROUND DATA Postoperative mortality is a rare event after bariatric surgery. Therefore, comprehensive data on mortality are lacking in the literature. METHODS A retrospective analysis of a large prospective database was carried out. The Italian Society of Obesity Surgery runs a National Registry on bariatric surgery where all procedures performed by members of the Society should be included prospectively. This Registry represents at present the largest database on bariatric surgery worldwide. RESULTS Between January 1996 and January 2006, 13,871 bariatric surgical procedures were included: 6122 adjustable silicone gastric bandings (ASGB), 4215 vertical banded gastroplasties (VBG), 1106 gastric bypasses, 1988 biliopancreatic diversions (BPD), 303 biliointestinal bypasses, and 137 various procedures. Sixty day mortality was 0.25%. The type of surgical procedure significantly influenced (P < 0.001) mortality risk: 0.1% ASGB, 0.15% VBG, 0.54% gastric bypasses, 0.8% BPD. Pulmonary embolism represented the most common cause of death (38.2%) and was significantly higher in the BPD group (0.4% vs. 0.07% VBG and 0.03% ASGB). Other causes of mortality were the following: cardiac failure 17.6%, intestinal leak 17.6%, respiratory failure 11.8%, and 1 case each of acute pancreatitis, cerebral ischemia, bleeding gastric ulcer, intestinal ischemia, and internal hernia. Therefore, 29.4% of patients died as a result of a direct technical complication of the procedure. Additional significant risk factors included open surgery (P < 0.001), prolonged operative time (P < 0.05), preoperative hypertension (P < 0.01) or diabetes (P < 0.05), and case load per Center (P < 0.01). CONCLUSIONS Mortality after bariatric surgery is a rare event. It is influenced by different risk factors including type of surgery, open surgery, prolonged operative time, comorbidities, and volume of activity. In defining the best bariatric procedure for each patient the different mortality risks should be taken into account. Choice of the procedure, prevention, early diagnosis, and therapy for cardiovascular complications may reduce postoperative mortality.

Abstract
BACKGROUND To report the prognosis and management of patients reoperated for severe intraabdominal sepsis (IAS) after bariatric surgery (S0) and admitted to the surgical intensive care unit (ICU) for organ failure. METHODS A French observational study in a 12-bed adult surgical intensive care unit in a 1,200-bed teaching hospital with expertise in bariatric surgery. From January 2001 to August 2006, 27 morbidly obese patients (18 transferred from other institutions) developed severe postoperative IAS (within 45 days). Clinical signs, biochemical and radiologic findings, and treatment during the postoperative course after S0 were reviewed. Time to reoperation, characteristics of IAS, demographic data, and disease severity scores at ICU admission were recorded and their influence on prognosis was analyzed. RESULTS The presence of respiratory signs after S0 led to an incorrect diagnosis in more than 50% of the patients. Preoperative weight (body mass index [BMI] > 50 kg/m2) and multiple reoperations were associated with a poorer prognosis in the ICU. The ICU mortality rate was 33% and increased with the number of organ failures at reoperation. CONCLUSION During the initial postoperative course after bariatric surgery, physical examination of the abdomen is unreliable to identify surgical complications. The presence of respiratory signs should prompt abdominal investigations before the onset of organ failure. An urgent laparoscopy, as soon as abnormal clinical events are detected, is a valuable tool for early diagnosis and could shorten the delay in treatment.

Abstract
BACKGROUND This is the first systematic review and meta-analysis of published mortality data after bariatric surgery. METHODS The review includes all papers published in English from January 1, 1990 to April 30, 2006, identified through electronic searches in MEDLINE, Current Contents, and the Cochrane Library, supplemented by manual reference checks. All accepted studies were assigned a level of evidence (Centre for Evidence-Based Medicine, Oxford, UK), and randomized controlled trials were rated for quality using the Jadad scoring method. Random effects meta-analyses were performed. Mortality was analyzed at either <or=30 days or 30 days to 2 years. RESULTS The data set includes 361 studies with 478 treatment arms and 85,048 patients. At baseline, the mean age was 40.0 years, body mass index was 47.4 kg/m2, 85% were female, and 11.5% had previous bariatric procedures. Meta-analysis of total mortality at <or=30 days was 0.28% (95% confidence interval [CI], 0.22-0.34) in 475 treatment arms (n = 84,931); total mortality at >30 days to 2 years was 0.35% (95% CI, 0.12-0.58) in 140 treatment arms (n = 19,928). Mortality at <or=30 day for all restrictive procedures was 0.30% (95% CI, 0.15-0.46) for open and 0.07% (95% CI, 0.02-0.12) for laparoscopic procedures; restrictive/malabsorptive (gastric bypass) was 0.41% (95% CI, 0.24-0.58] for open and 0.16% (95% CI, 0.09-0.23) for laparoscopic; and malabsorptive was 0.76% (95% CI, 0.29-1.23) for open and 1.11% (95% CI, 0.00-2.70) for laparoscopic. Subgroup analyses of <or=30-day mortality show a male:female ratio of 4.74:0.13, with 1.25% (95% CI, 0.56-1.94) incidence in the superobese and 0.34% (95% CI, 0.00-1.29) in the elderly (>or=65 years). CONCLUSION The early and late mortality rates after bariatric surgery are low and can be subjected to risk stratification for comparative analyses and prospective risk assessments.

Abstract
BACKGROUND The outcomes of Medicare patients undergoing bariatric surgery have been particularly scrutinized, especially with the Center of Medicare and Medicaid Services' decision to offer bariatric surgery benefits. METHODS The length-of-stay (LOS) data were analyzed from the National Hospital Discharge Survey from 2002 to 2004. To test the hypothesis that Medicare and Medicaid beneficiaries were more likely to have a prolonged length of stay (PLOS), we used a multivariate logistic regression model controlling for age, gender, hospital size, and year of procedure. RESULTS An estimated 312,000 bariatric procedures were performed nationally from 2002 to 2004. The average patient age was 41.5 years (range 14-75) and 83.6% were women. The in-hospital mortality rate was reported to be .17%. A PLOS occurred in 3.7% of the population. The Medicare and Medicaid beneficiaries represented 5.7% and 6.2% of the population, respectively. The Medicare beneficiaries were 6.0 times (95% confidence interval 2.5-14; P <.001) as likely to have a PLOS, and Medicaid beneficiaries were 3.2 times (95% confidence interval 1.2-8.9; P = .02) as likely to have a PLOS as others after controlling for age, gender, hospital size, and year of procedure. For every 10-year increase in age, the risk of a PLOS increased by 30% (P <.012). CONCLUSION Medicare and Medicaid beneficiaries are both at an increased risk of a PLOS. This study was not designed to identify the potential causes of a PLOS. Data from prospectively collected bariatric registries might aid surgeons in assessing the risk/benefit ratio of surgical interventions in groups regarded as high risk.

Abstract
The bariatric surgery community is complaining about the multiple barriers that hamper the growth of procedures that have been found to be the only effective treatment for morbid obesity. The French situation demonstrates that the number of procedures has stabilized after a period of rapid growth, despite the facts that the needs are not satisfied and that there are less important barriers to surgery than in most countries. This new "French paradox" is understandable if one accepts the reluctance of the public audience and an insufficient level of evidence for a systematic referral to bariatric surgery. Less invasive procedures should make it possible to re-unify the physicians who deal with obesity, as well as the implementation of comparatives and randomized clinical studies.
