Abstract
PURPOSE Bariatric surgery is associated with a greater venous thromboembolism (VTE) risk in the weeks following surgery, but the long-term risk of VTE is incompletely characterized. We evaluated bariatric surgery in relation to long-term VTE risk. MATERIALS AND METHODS This population-based retrospective matched cohort study within three United States-based integrated health care systems included adults with body mass index (BMI) ≥ 35 kg/m2 who underwent bariatric surgery between January 2005 and September 2015 (n = 30,171), matched to nonsurgical patients on site, age, sex, BMI, diabetes, insulin use, race/ethnicity, comorbidity score, and health care utilization (n = 218,961). Follow-up for incident VTE ended September 2015 (median 9.3, max 10.7 years). RESULTS Our population included 30,171 bariatric surgery patients and 218,961 controls; we identified 4068 VTE events. At 30 days post-index date, bariatric surgery was associated with a fivefold greater VTE risk (HRadj = 5.01; 95% CI = 4.14, 6.05) and a nearly fourfold greater PE risk (HRadj = 3.93; 95% CI = 2.87, 5.38) than no bariatric surgery. At 1 year post-index date, bariatric surgery was associated with a 48% lower VTE risk and a 70% lower PE risk (HRadj = 0.52; 95% CI = 0.41, 0.66 and HRadj = 0.30; 95% CI = 0.21, 0.44, respectively). At 5 years post-index date, lower VTE risks persisted, with bariatric surgery associated with a 41% lower VTE risk and a 55% lower PE risk (HRadj = 0.59; 95% CI = 0.48, 0.73 and HRadj = 0.45; 95% CI = 0.32, 0.64, respectively). CONCLUSION Although in the short-term bariatric surgery is associated with a greater VTE risk, in the long-term, it is associated with a substantially lower risk.

Abstract
Background: Bariatric surgery is a frequently performed procedure in the United States, accounting for ∼40,000 procedures annually. Patients undergoing bariatric surgery are at high risk for postoperative thrombosis, with a venous thromboembolism (VTE) rate of up to 6.4%. Despite this risk, there is a lack of guidelines recommending postoperative VTE prophylaxis and it is not routine practice at most hospitals. The postoperative bleeding rate after bariatric surgery is only 1.5%; however, the risk of bleeding may lead to hesitancy for more liberal VTE prophylaxis. Methods: This is a retrospective analysis of bariatric surgeries at a single institution in 2019 and 2021. Data were obtained from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) and electronic medical record review for all patients undergoing sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), or conversion to RYGB. The primary outcomes were composite bleeding events, which included postoperative transfusion, postoperative endoscopy or return to operating room (OR) (for bleeding), intra-abdominal hematoma, gastrointestinal (GI) bleeding, or incisional hematoma. Results: There were a total of 2067 patients in the cohort, with 1043 surgeries in 2019 and 1024 surgeries in 2021. There was no difference between bleeding events after instituting a deep venous thrombosis (DVT) prophylaxis protocol in 2021 (27 versus 28 events, P = .76). There was no difference in individual bleeding events between 2019 and 2021. Additionally, there was no significant difference in the rate of VTE between 2019 and 2021 (2 versus 5 events, P = .28). Conclusions: After instituting a standard protocol of prophylactic heparin postdischarge, we did not find an increased rate of bleeding events in patients undergoing bariatric surgery. Thus, surgeons can consider prescribing postdischarge chemical VTE prophylaxis without concern for bleeding.

Predicting short-term thromboembolic risk following Roux-en-Y gastric bypass using supervised machine learning. World J Gastrointest Surg 2024; 16:1097-1108. [PMID: 38690043 PMCID: PMC11056662 DOI: 10.4240/wjgs.v16.i4.1097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 02/07/2024] [Accepted: 03/05/2024] [Indexed: 04/22/2024] Open
Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is a widely recognized bariatric procedure that is particularly beneficial for patients with class III obesity. It aids in significant weight loss and improves obesity-related medical conditions. Despite its effectiveness, postoperative care still has challenges. Clinical evidence shows that venous thromboembolism (VTE) is a leading cause of 30-d morbidity and mortality after RYGB. Therefore, a clear unmet need exists for a tailored risk assessment tool for VTE in RYGB candidates. AIM To develop and internally validate a scoring system determining the individualized risk of 30-d VTE in patients undergoing RYGB. METHODS Using the 2016-2021 Metabolic and Bariatric Surgery Accreditation Quality Improvement Program, data from 6526 patients (body mass index ≥ 40 kg/m2) who underwent RYGB were analyzed. A backward elimination multivariate analysis identified predictors of VTE characterized by pulmonary embolism and/or deep venous thrombosis within 30 d of RYGB. The resultant risk scores were derived from the coefficients of statistically significant variables. The performance of the model was evaluated using receiver operating curves through 5-fold cross-validation. RESULTS Of the 26 initial variables, six predictors were identified. These included a history of chronic obstructive pulmonary disease with a regression coefficient (Coef) of 2.54 (P < 0.001), length of stay (Coef 0.08, P < 0.001), prior deep venous thrombosis (Coef 1.61, P < 0.001), hemoglobin A1c > 7% (Coef 1.19, P < 0.001), venous stasis history (Coef 1.43, P < 0.001), and preoperative anticoagulation use (Coef 1.24, P < 0.001). These variables were weighted according to their regression coefficients in an algorithm that was generated for the model predicting 30-d VTE risk post-RYGB. The risk model's area under the curve (AUC) was 0.79 [95% confidence interval (CI): 0.63-0.81], showing good discriminatory power, achieving a sensitivity of 0.60 and a specificity of 0.91. Without training, the same model performed satisfactorily in patients with laparoscopic sleeve gastrectomy with an AUC of 0.63 (95%CI: 0.62-0.64) and endoscopic sleeve gastroplasty with an AUC of 0.76 (95%CI: 0.75-0.78). CONCLUSION This simple risk model uses only six variables to assist clinicians in the preoperative risk stratification of RYGB patients, offering insights into factors that heighten the risk of VTE events.

Abstract
Background To determine how patients who underwent bariatric surgery at a tertiary hospital in Korea first considered and then decided to get the surgery and identify information gaps among patients and healthcare professionals. Methods This study included 21 patients who underwent bariatric surgery to treat morbid obesity (body mass index [BMI] ≥35 or ≥30 kg/m2 together with obesity-related comorbidities) between August 2020 and February 2022. A telephone interview was conducted with the patients after at least 6 months had elapsed since the surgery. We asked how the patients decided to undergo bariatric surgery. We also inquired about their satisfaction with and concerns about the surgery. Results Seventy-one percent of the patients were introduced to bariatric surgery following a recommendation from healthcare professionals, acquaintances, or social media. Most of the patients (52%) decided to undergo bariatric surgery based on recommendations from healthcare professionals in non-surgical departments. Satisfaction with the information provided differed among the patients. Post-surgical concerns were related to postoperative symptoms, weight regain, and psychological illness. Conclusion Efforts are needed to raise awareness about bariatric surgery among healthcare professionals and the public. Tailored pre- and postoperative consultation may improve quality of life after bariatric surgery.

Abstract
Bariatric surgery has emerged as a highly effective option for individuals with obesity, offering significant and sustainable weight loss outcomes. This surgical approach involves various procedures that alter the anatomy of the gastrointestinal tract, leading to reduced food intake and nutrient absorption. Established procedures such as sleeve gastrectomy, gastric bypass, adjustable gastric banding, and biliopancreatic diversion with duodenal switch have proven track records. In contrast, emerging options like intragastric balloons, AspireAssist devices, and endoscopic sleeve gastroplasty show promise but require further investigation. Numerous studies have highlighted the remarkable benefits of bariatric surgery, not only in weight loss but also in the resolution of obesity-related comorbidities and significant improvements in quality of life. However, successful outcomes rely on a multidisciplinary approach, encompassing preoperative evaluation, patient selection, comprehensive postoperative care, nutritional support, and psychological counseling. Regular follow-up and adherence to postsurgical recommendations are crucial for sustained weight loss and positive long-term results. As bariatric surgery continues to evolve, tailored procedures based on individual needs and ongoing research hold the potential for even more refined and effective approaches. Through this ongoing advancement, bariatric surgery is poised to offer improved patient outcomes, transforming lives for those grappling with the challenges of obesity.

Abstract
INTRODUCTION Nowadays, a large number of bariatric surgery (BS) procedures are undertaken worldwide as surgery has become an efficient strategy to treat the obesity epidemic. The risk of venous thromboembolism (VTE) is increased in patients undergoing BS not only due to the intrinsic surgical risk but also because patients with obesity have a 2-3-fold higher risk of VTE. The optimal strategy for VTE prevention in BS setting, including optimal dose and thromboprophylaxis regimen, is still not fully clarified. The aim of this study was to report a bariatric high-volume center experience and to propose a practical thromboprophylaxis protocol for this population. METHODS A single-center, observational, retrospective, and longitudinal study was conducted from January 2018 to December 2020, a total of 901 patients who underwent primary and revisional bariatric surgery were included. RESULTS The overall frequency of VTE events was 0.44% (n=4), one patient had pulmonary embolism (PE) during index hospital admission; another patient had simultaneous deep venous thrombosis (DVT) and PE, two months after surgery; and two other patients had DVT, nine and 16 months after surgery. The median time for VTE was four months. The incidence of females was 75% (n=3) and the median age was 57 years. Only one female patient was using oral contraception. None had a previous history of thromboembolic events, chronic venous insufficiency, or other known diseases that could increase the VTE risk. CONCLUSION Considering the outcomes reported by this experienced center with low rates of thromboembolic events, we suggest a thromboprophylaxis protocol that can be easily applied to the majority of bariatric patients.

Abstract
Prophylactic placement of inferior vena cava (IVC) filters prior to performing bariatric surgery is an intervention of unclear safety and efficacy with disagreement between current practice guidelines. To better characterize the risk and benefit of IVC filter insertion prior to bariatric surgery based on the current evidence. A systematic review of the literature of patients with prophylactic IVC filter insertion prior to bariatric surgery was performed and 32 studies were identified for inclusion into the review, of which none were randomized controlled trials. Meta-analysis was performed including the high-quality included studies. Seven high quality studies reported thrombotic events in patients undergoing bariatric surgery who had an IVCF and a control group which allowed for meta-analysis. The pooled odds ratio of venous thrombotic events in the IVC filter population versus the group without IVC filters was 1.57 (95%CI 0.89, 2.76). Among high quality studies 5 reported major bleeding with a rate of 0.76% and 6 reported on IVC filter complications with a rate of 0.67%. Overall no significant reduction in the rate of venous thrombosis was found with prophylactic IVC filter insertion. Use of IVC filters for prophylaxis remains a concern given the lack of clear efficacy in this setting and a small but present complication risk.

Abstract
Background Enhanced recovery after bariatric surgery (ERABS) is an approach developed to improve outcomes in obese surgical patients. Unfortunately, it is not evenly implemented in Italy. The Italian Society for the Surgery of Obesity and Metabolic Diseases and the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care joined in drafting an official statement on ERABS. Methods To assess the effectiveness and safety of ERABS and to develop evidence-based recommendations with regard to pre-, intra-, and post-operative care for obese patients undergoing ERABS, a 13-member expert task force of surgeons and anesthesiologists from Italian certified IFSO center of excellence in bariatric surgery was established and a review of English-language papers conducted. Oxford 2011 Levels of Evidence and U.S. Preventive Services Task Force Grade Definitions were used to grade the level of evidence and the strength of recommendations, respectively. The supporting evidence and recommendations were reviewed and discussed by the entire group at meetings to achieve a final consensus. Results Compared to the conventional approach, ERABS reduces the length of hospital stay and does not heighten the risk of major post-operative complications, re-operations, and hospital re-admissions, nor does it increase the overall surgical costs. A total of 25 recommendations were proposed, covering pre-operative evaluation and care (7 items), intra-operative management (1 item, 11 sub-items), and post-operative care and discharge (6 items). Conclusions ERABS is an effective and safe approach. The recommendations allow the proper management of obese patients undergoing ERABS for a better outcome.

Does timing of IVC filter placement in bariatric surgery patients impact perioperative outcomes? Langenbecks Arch Surg 2022; 407:2327-2335. [PMID: 35618949 DOI: 10.1007/s00423-022-02532-6] [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: 12/06/2021] [Accepted: 04/24/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Metabolic and bariatric surgery (MBS) remains a safe and effective treatment for morbid obesity with a low-risk profile. Venous thromboembolism (VTE) remains the most common cause of mortality. There is increasing consensus that inferior vena cava (IVC) filter use is associated with more harm than benefit. Our study aim was to determine if the timing of IVC filter placement correlates with VTE complications. METHODS The 2015-2019 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program databases were used to identify Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) patients who had an IVC filter at the time of bariatric procedure. Selected cases were stratified by IVC placement timing. Propensity-score matching estimated the probabilities of receiving pre-existing vs. prophylactic IVC placement. Resultant models were then used to assess VTE complications. Statistical analyses were performed with Stata MP version 16. A p-value < 0.05 was considered significant. RESULTS In total, 228,986 RYGB and 568,386 SG cases were analyzed, and 0.6% and 0.5% had an IVC filter. Prophylactic IVC filter use declined annually, but not pre-existing filters. VTE and VTE-related mortality were significantly higher in filter vs. no filter cohorts (p<0.001). Propensity matching reduced biases between RYGB and SG IVC filter cohorts (pre-existing vs. prophylactic). There were no differences in the RYGB pre-existing and prophylactic IVC filter cohorts; however; for SG cases, pre-existing IVC filters compared to prophylactic IVC filters were associated with decreased odds of having a VTE (OR: 0.97, 95% CI: 0.95, 0.99). CONCLUSION Compared to a pre-existing filter, the presence of a prophylactic IVC filter in SG patients was associated with a higher likelihood of VTE. HIGHLIGHTS 1. Annual use of prophylactic IVC filter is bariatric surgery patients is decreasing. 2. The presence of a pre-existing IVC filter remain constant. 3. Any IVC filter presence at time of MBS increased VTE and VTE-related mortality and morbidity. 4. In SG cases, prophylactic IVC filter was associated with higher rates of VTE and VTE-related mortality.

[PMID: 35478402 DOI: 10.1007/s11695-022-06051-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 03/29/2022] [Accepted: 04/07/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND Thromboprophylaxis in bariatric surgery is widely debated; however, few large articles evaluate treatment plans and their efficacy. Herein, we make the first large-scale report of the safety and efficacy of apixaban (Eliquis) for thrombus prevention following bariatric surgery. PURPOSE To evaluate the safety and efficacy of apixaban following bariatric surgery. SETTING Three private institutes, USA. MATERIALS AND METHODS Data from 5017 consecutive bariatric patients that were placed on postoperative apixaban for thromboprophylaxis were used for retrospective analysis. The dose prescribed to patients was 2.5 mg PO BID for a total of 30 days starting on day 3 postoperatively. RESULTS In total, of the 5017 patients, 59.7%, 31.2%, 4.4%, 2.5%, 1.8%, and 0.1% of the patients had undergone sleeve gastrectomy (SG), single-anastomosis duodeno-ileal bypass with SG (SADI-S), Roux-en-Y gastric bypass (RYGB), conversion from SG to SADI, small bowel reconstruction, and RYGB reversal, respectively. The 30-day follow-up rate was 95.3%. In total, 1.7% of patients experienced apixaban-related side effects. The most common side effects were menorrhagia and rash. Two (0.03%) side effects developed into Clavien-Dindo grade II complications. Overall, 10 (0.1%) patients experienced thromboembolic complications (five (0.09%) PVTs and five (0.09%) PEs). In each case, the protocol was not followed for extenuating circumstances. There were no deaths or thromboembolic events in cases where the protocol was able to be fully followed. CONCLUSIONS In conclusion, 30 days of postoperative apixaban appears to be safe and effective with minimal side effects while preventing thromboembolic events.

Abstract
OBJECTIVE To determine the thrombotic and hemorrhagic risk in bariatric surgery with multimodal rehabilitation programs, comparing two guidelines of pharmacological prophylaxis recommended in the Guide to the Spanish Society for Obesity Surgery and the Obesity Section of the AEC. METHODS Cohorts retrospective study from January-2010 to December-2019. Cases of vertical gastrectomy or gastric bypass were recorded, systematically applying multimodal rehabilitation protocols. Two reduced chemoprophylaxis regimens were analyzed, starting after surgery and maintained for 10 days; one with fondaparinux (Arixtra®) at a fixed dose of 2.5mg/day and the other with enoxaparin (Clexane®) with a single daily dose adjusted to BMI: 40mg/day for BMI of 35-40 and 60mg/day for BMI 40-60. RESULTS 675 patients were included; 354 with Fondaparinux-Arixtra® during the period 2010-2015 and 321 with Enoxaparin-Clexane® during the period 2016-2019. There were no cases of DVT or clinical PE. However, the incidence of hemorrhage requiring reoperation, transfusion, or a decrease of more than 3g/dL hemoglobin was 4.7%, with no difference between groups. Mortality was nil. The average stay was 2.8 days and the outpatient follow-up was 100% during the first 6 months and 95% at 12 months. CONCLUSIONS The combination of multimodal rehabilitation programs and mechanical and pharmacological thromboprophylaxis by experienced teams, reduces the risk of thromboembolic events and could justify reduced chemoprophylaxis regimens to decrease the risk of postoperative bleeding.

Abstract
Patients with an oncologic disease requiring cytoreductive surgery and hyperthermic intraperitoneal chemotherapy may also present with morbid obesity. In some patients, it may be possible to offer bariatric surgery such as sleeve gastrectomy in combination with their cancer resection to treat both diseases concurrently. Two such cases are described where sleeve gastrectomy was done alongside the primary oncologic surgery in the same procedure. Our patients had long-term follow-ups and their overall outcomes were favorable. They achieved remission and acceptable levels of weight loss over their several years of follow-up appointments. The added benefit of bariatric surgery may decrease long-term morbidity and mortality in carefully selected patients. More studies are indicated to fully understand the risks of benefits of this combined procedure in order to offer it on a wider scale.

Abstract
Bariatric and metabolic surgery is a safe and effective treatment of morbid obesity, a disease that continues to increase in prevalence in the United States and worldwide. The two most commonly performed operations are the sleeve gastrectomy and the gastric bypass. Early and late complications can occur, and although referral to a bariatric surgeon or center is ideal, emergency management of acute problems is relevant to all general surgeons. Bariatric surgery can have surgical and metabolic consequences. An understanding of the altered anatomy and physiology helps to guide management of morbidities. This article discusses surgical postoperative complications and metabolic complications.

Abstract
Obesity is an inflammatory state related to vascular endothelium dysfunction. It generates a biological situation of hypercoagulability increasing the risk of thrombosis. This prothrombotic condition could be improved by bariatric surgery.The main objective was to analyze the impact of bariatric surgery on cardiovascular risk factors (CVRF) associated with changes in thrombin generation and procoagulant activity of microparticles (MP).We present a prospective longitudinal study including consecutive patients candidate for bariatric surgery. We performed 3 sequential clinical visits: at inclusion, before surgery after completing the modified fasting phase, and 6 months after surgery. We analyzed CVRF, thrombin generation, and MP activity. The data analysis was performed using a logistic regression model to determine changes over time of hemostatic parameters and body mass index (BMI). McNemar test for binary variables was used to analyze the CVRF.We included 94 patients (66 women), with an average age of 45.7 ± 10.1 years. The mean BMI reduction at the end of the follow-up was 15.5 ± 4.2 kg/m2. We detected a statistically significant improvement in CVRF: hypertension, diabetes mellitus, dyslipidemia, and obstructive sleep apnea, as well as a significant reduction in thrombin generation capacity and procoagulant MP activity.Massive weight loss induced by bariatric surgery improves the cardiovascular profile, associated with a reduction in the hypercoagulable status.

Abstract
Background Venous thromboembolic events (VTE) post-bariatric surgery (BS) lead to morbidity and mortality. Methods This scoping review assessed whether reported VTE post-BS could be under/over-estimated; suggested a possible number of VTE post-BS; appraised whether VTE are likely to decrease/increase; examined BS as risk/protective factor for VTE; and mapped the gaps, proposing potential solutions. Results VTE appears under-estimated due to: identification/coding of BS and VTE; reporting of exposure (BS); and reporting of outcomes (VTE). The review proposes a hypothetical calculation of VTE post-BS. VTE are unlikely to decrease soon. BS represents risk and protection for VTE. Better appreciation of VTE-BS relationships requires longer-term strategies. Conclusion VTE are underestimated. Actions are required for understanding the VTE-BS relationships to in order to crease VTE by better-informed prevention strategy/ies.

Transversus Abdominis Plane Block Appears to Be Effective and Safe as a Part of Multimodal Analgesia in Bariatric Surgery: a Meta-analysis and Systematic Review of Randomized Controlled Trials. Obes Surg 2020; 31:531-543.

Abstract
Purpose Pain after bariatric surgery can prolong recovery. This patient group is highly susceptible to opioid-related side effects. Enhanced Recovery After Surgery guidelines strongly recommend the administration of multimodal medications to reduce narcotic consumption. However, the role of ultrasound-guided transversus abdominis plane (USG-TAP) block in multimodal analgesia of weight loss surgeries remains controversial. Materials and Methods A systematic search was performed in four databases for studies published up to September 2019. We considered randomized controlled trials that assessed the efficacy of perioperative USG-TAP block as a part of multimodal analgesia in patients with laparoscopic bariatric surgery. Results Eight studies (525 patients) were included in the meta-analysis. Pooled analysis showed lower pain scores with USG-TAP block at every evaluated time point and lower opioid requirement in the USG-TAP block group (weighted mean difference (WMD) = − 7.59 mg; 95% CI − 9.86, − 5.39; p < 0.001). Time to ambulate was shorter with USG-TAP block (WMD = − 2.22 h; 95% CI − 3.89, − 0.56; p = 0.009). This intervention also seemed to be safe: only three non-severe complications with USG-TAP block were reported in the included studies. Conclusion Our results may support the incorporation of USG-TAP block into multimodal analgesia regimens of ERAS protocols for bariatric surgery.

Abstract
BACKGROUND Bariatric procedures are the most effective management for obesity. There is no standard venous thromboembolism (VTE) prophylaxis for both dosing and duration of anticoagulation following laparoscopic sleeve gastrectomy. Our purpose was to assess the optimum regimen for VTE prophylaxis in bariatric procedures and to reduce the incidence of perioperative bleeding. METHODS AND MATERIALS This is a prospective randomized study which involved 100 morbidly obese patients, subdivided into two groups; group A received postoperative low molecular weight heparin (LMWH) prophylaxis alone starting from day 1 to day 15 in dose 1 mg/kg/day in a maximum dose 120 mg/day, and group B received both pre- and postoperative LMWH; at night of surgery 12 h preoperatively and postoperative starting from day 1 to day 15 with the same dose. All patients underwent mesenteric and bilateral lower limbs duplex 15 days postoperative using Philips iU machine and linear (L9-3), convex (C5-1) and sector (S5-1) probes. RESULTS Regarding postoperative VTE, we found statistically significant increase in postoperative VTE in patients of group A (four cases) without any case complicated with VTE in patients of group B (P value = 0.041). Regarding postoperative bleeding, we found statistically insignificant percent of cases complicated with postoperative bleeding in group B compared to group A (P value 0.315). CONCLUSION Preoperative as well as a postoperative prophylactic anticoagulant as LMWH is recommended to prevent perioperative VTE. There was an insignificant increase in postoperative bleeding in patients who received preoperative prophylactic anticoagulants.

Abstract
Venous Thromboembolic Events after Bariatric Surgery. This protocol undertakes a systematic review and metanalysis of venous thromboembolic events after bariatric surgery. Methodology, searches, eligibility, and data extraction for analysis are described. Following the PRISMA guidelines, it describes the approach for pooled estimates. Findings will have key clinical consequences for patient care.
Introduction Considerably large numbers of bariatric surgery (BS) procedures are undertaken globally, and are projected to increase with the obesity epidemic. Venous thromboembolic events (VTE) comprise an important cause of postoperative morbidity and mortality after BS and an important issue with wide clinical and financial repercussions. Yet, a precise extent of the prevalence of VTE after BS for obesity and its mortality remains uncertain. Methods and analysis In order to respond to this knowledge gap, we will conduct a systematic review and meta-analysis of the prevalence of and mortality associated with VTE after BS. This protocol outlines the methodology that will be used and the search strategies and eligibility criteria that will be utilized to identify and select studies, as well as the method by which data from the selected studies will be extracted for analysis. PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry Platform, Cochrane Library, MEDLINE, Scopus, clinicaltrials.gov and Google scholar will be searched from 01 January 1990 through 10th April 2020, for original studies written in English that provided prevalence estimates of VTE after BS. Articles will also be searched for mortality estimates of VTE after BS. STROCSS (Strengthening the Reporting of Cohort Studies in Surgery) criteria will evaluate the methodological quality of the selected studies. The use of fixed effect or random effects model will be subject to the findings of the statistical tests for heterogeneity. Publication bias will be visually estimated by inspecting the funnel plots. Pooled estimates will be computed. Th current protocol conforms to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines and has been submitted to the PROSPERO International Prospective Register of systematic reviews. No ethical clearance is required for this study. This systematic review and meta-analysis will be published in a peer-reviewed journal and presented at national and international conferences.

Abstract
Despite the high proportion of obese patients this population remains understudied in the field of venous thromboembolic disease (VTE). Obesity is a risk factor for pulmonary embolism and/or deep vein thrombosis, especially when it is associated with other risk factors for VTE. Currently there is no validated diagnostic algorithm for VTE in the population of obese patients. Moreover, imaging examinations can be of poor quality and inconclusive. In the prevention of VTE, data concerning obese patients are mainly based on low-level studies. Apart from the context of bariatric surgery, an adjustment of heparin doses according to the weight of the patient is proposed only on a case-by-case basis. According to the current guidelines, therapeutic fixed dose oral anticoagulants should not be prescribed for patients with weights exceeding 120kg or a body mass index>40kg/m2. Heparin doses should be weight adjusted and monitored with anti-Xa activity. Anti vitamin K can be prescribed but require INR monitoring. Therefore, new studies specifically dedicated to obese patients are required in the field of VTE for better diagnostic and therapeutic management.

CONCLUSIONS Bariatric procedures remain a safe and effective intervention for higher-risk patients with obesity. Clinical decision-making should be evidence based within the context of a chronic disease. A team approach to perioperative care is mandatory, with special attention to nutritional and metabolic issues.

Abstract
OBJECTIVE The aim of this study is to evaluate the effect of bariatric surgery on long-term risk of VTEs in a large cohort of patients with obesity. BACKGROUND Obesity is a well-established risk factor for VTEs, such as pulmonary embolism and deep vein thrombosis. The rising prevalence of obesity and its associated co-morbidities, including VTE, represent a growing public health issue. METHODS A nested, retrospective matched cohort study was designed and conducted on prospectively collected national electronic healthcare records data from the Clinical Practice Research Datalink. Eight thousand, one hundred twelve patients were included in the study: the 4056 patients on the database who had undergone bariatric surgery, and equal numbers of age, sex, and body mass index matched controls. The primary endpoint was the occurrence of VTEs; secondary endpoints were the occurrence of deep vein thrombosis alone, pulmonary embolism alone. RESULTS Patients were followed up for a median of 10.7 years. The bariatric surgery cohort had a significantly lower occurrence of the primary outcome [hazard ratio (HR) 0.601; 95% confidence interval (CI) 0.430-0.841, P = 0.003]; mainly driven by a reduction in deep vein thrombosis (HR 0.523; 95% CI 0.349-0.783, P = 0·002) and not in pulmonary embolism (HR 0.882; 95% CI 0.511-1.521, P = 0.651). CONCLUSIONS The results of this nation-wide study set out to characterize the impact of bariatric surgery on long-term risk of thromboembolic events outline a significant reduction in thromboembolic events, driven by a reduction in deep vein thrombosis.

Abstract
BACKGROUND Postoperative venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), are the leading causes of morbidity and mortality after bariatric surgery. Although several studies have examined VTE, few have examined risk factors separately for DVT and PE after contemporary bariatric surgery, including laparoscopic sleeve gastrectomy (LSG). Our objective was to define risk factors for DVT and PE independently for both LSG and laparoscopic Roux-en-Y gastric bypass (LRYGB) patients using the largest validated bariatric surgery database. METHODS The metabolic and bariatric surgery accreditation and quality improvement program (MBSAQIP) database was queried to identify patients who underwent LSG or LRYGB between January 2015 and December 2017. Perioperative data were compared using bivariate analysis. Risk of DVT and PE after LSG or LRYGB was determined using multivariable logistic regression analysis. RESULTS During the study period, 369,032 bariatric cases (72% LSG, 28% LRYGB) were performed. The incidence of DVT was similar between LSG and LRYGB (0.2% vs. 0.2%, p = 0.96), while the incidence of PE was decreased for LSG compared to LRYGB (0.1% vs. 0.2%, p < 0.001). Operative length was associated with increased risk of postoperative DVT (OR 1.1, CI 1.01-1.30, p = 0.04) and postoperative PE (OR 1.4, CI 1.16-1.64, p < 0.001) after surgery. The largest independent risk factors for DVT were history of DVT (OR 6.2, CI 4.44-8.45, p < 0.001) and transfusion (OR 4.2, CI 2.48-6.63, p < 0.001). The largest independent risk factors for PE were transfusion (OR 5.0, CI 2.69-8.36, p < 0.001) and history of DVT (OR 2.8, CI 1.67-4.58, p < 0.001). LSG was associated with a decreased risk of PE compared to LRYGB (OR 0.7 CI 0.55-0.91, p = 0.01). CONCLUSIONS Prolonged operative length is associated with a higher risk of DVT and PE after either LSG or LRYGB. Transfusion and history of DVT are the largest risk factors for developing DVT and PE. There is a decreased risk of PE after LSG compared to LRYGB.

Abstract
Obesity is a growing problem around the world, and radiology departments frequently encounter difficulties related to large patient size. Diagnosis and management of suspected venous thromboembolism, in particular deep venous thrombosis (DVT) and pulmonary embolism (PE), are challenging even in some lean patients, and can become even more complicated in the setting of obesity. Many obstacles must be overcome to obtain imaging examinations in obese patients with suspected PE and/or DVT, and to ensure that these examinations are of sufficient quality to diagnose or exclude thromboembolic disease, or to establish an alternative diagnosis. Equipment limitations and technical issues both need to be acknowledged and addressed. Table weight limits and scanner sizes that readily accommodate obese and even morbidly obese patients are not in place at many clinical sites. There are also issues with image quality, which can be substantially compromised. We discuss current understanding of the effects of patient size on imaging in general and, more specifically, on the imaging modalities used for the diagnosis and treatment of DVT and PE. Emphasis will be placed on the technical parameters and protocol nuances, including contrast dosing, which are necessary to refine and optimize images for the diagnosis of DVT and PE in obese patients, while remaining cognizant of radiation exposure. More research is necessary to develop consistent high-level evidence regarding protocols to guide radiologists, and to help them effectively utilize emerging technology.

Abstract
Nearly 160 million Americans are overweight, obese, or morbidly obese. Morbid obesity and its numerous comorbidities are threats to a person's health. Moreover, hospitalized individuals living with adiposity-based chronic conditions are at risk for certain immobility hazards. Many individuals who are morbidly obese look to metabolic surgery as a means for achieving sustainable weight loss. This article addresses critical care needs of people living with excess weight or weight maldistribution, along with specific needs of those undergoing metabolic surgery.

Abstract
The obesity epidemic in the United States has increased greatly over the past several decades, and thoracic surgeons are likely to see obese patients routinely in their practices. Obesity has direct deleterious health effects such as metabolic disorder and cardiovascular disease, and is associated with many cancers. Obese patients who need thoracic surgery pose practical challenges to many of the routine elements in perioperative management. Preoperative assessment of obesity-related comorbid conditions and risk stratification for surgery, thorough intraoperative planning for anesthesia and surgery, and postoperative strategies to optimize pulmonary hygiene and mobility minimize the risk of adverse outcomes.

Abstract
Contexto A cirurgia bariátrica é considerada a melhor opção para o tratamento da obesidade, cujos pacientes são considerados de alto risco para fenômenos tromboembólicos. Objetivos Comparar o uso de doses diferentes de heparina de baixo peso molecular (HBPM) na profilaxia da trombose venosa profunda (TVP) em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, alteração na dosagem do fator anti-Xa e sangramento pré ou pós-operatório. Métodos Estudo comparativo transversal em pacientes submetidos à cirurgia bariátrica distribuídos em dois grupos, que receberam doses de HBPM de 40 mg (grupo controle, GC) e 80 mg (grupo de estudo, GE). Foram avaliados por ultrassonografia vascular e dosagem de KPTT, TAP, plaquetas e fator anti-Xa. Resultados Foram avaliados 60 pacientes, sendo 34 no GC e 26 no GE. Foi observada diferença significativa somente no peso (p = 0,003) e índice de massa corporal (p = 0,018) no GE em relação ao GC. Não houve diferença na dosagem de KPTT, TAP, plaquetas e fator anti-Xa entre os grupos. Não foram detectados TVP ou sangramentos significativos em ambos os grupos. Conclusões Não houve diferença estatisticamente significativa na utilização de doses maiores de HBPM na profilaxia da TVP em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, dosagem do fator anti-Xa e sangramento pré ou pós-operatório.

Abstract
Background Obesity is known as a major risk factor for postoperative vein thrombosis. Thromboelastography (TEG) is used to monitor viscoelastic features of blood clots. The aim of this study was to determine hypercoagulable states in patients undergoing bariatric surgery and to assess dynamics of coagulation parameters in the perioperative setting using TEG. Material/Methods We included 60 consecutive patients undergoing bariatric surgery. TEG alterations were assessed at 4 time points: at baseline, after the surgery, and on postoperative day 1 (POD1) and 2 (POD2). Hypercoagulable state was defined when patients showed clot strength (G) of ≥11 dynes/cm2 or maximum amplitude (MA) ≥68 mm. Results Fourteen patients (23.3%) out of 60 showed hypercoagulability prior to surgery on TEG. Fibrinogen levels were significantly higher in the G ≥11 group compared to the G <11 group, at 4.2 and 3.8 g/l, respectively (p=0.02). Seventeen patients (28.3%) had MA ≥68 mm at baseline. Fibrinogen levels increased significantly from 3.90 at baseline to 4.16 g/l in POD2 (p<0.001). There was an increase in mean reaction time from baseline (6.74 s) to POD2 (7.43 s, p=0.022). We found a correlation between baseline fibrinogen levels and MA (R=0.431, p=0.001) or G (R=0.387, p=0.003). ROC curve analysis showed that fibrinogen levels can predict clot strength (G) ≥11 dynes/cm2 with AUC=0.680 (p=0.044). Conclusions A considerable proportion of patients referred to bariatric surgery show a trend towards hypercoagulability on TEG. This study shows the potential of hypercoagulation monitoring by TEG in the perioperative setting of bariatric surgery.

Abstract
Bariatric surgery has proven to be highly effective in controlling obesity and metabolic syndrome; the results of this surgery are not only expressed in terms of weight loss, but also in terms of resolution of comorbidities, improved quality of life and complications. The different parameters used to measure these outcomes require uniformity and reference patterns. Therefore, it is essential to identify those indicators and quality criteria that are helpful in defining the «best practice» principles in bariatric surgery. In this regard, the Section of Obesity of the Spanish Association of Surgeons, in collaboration with the Spanish Society for Bariatric Surgery (SECO), present as an objective to identify the key points that define «quality» in this type of surgery. We describe the main indicators based on the published literature as well as the criteria for referral of the main comorbidities according to the evidence found and grades of recommendation.

Abstract
Obesity and inflammatory bowel disease (IBD) are systemic inflammatory disorders that predispose to arterial and venous thrombosis through similar prothrombotic mechanisms. Obesity and IBD are chronic risk factors that lead to a persistently elevated risk of thrombosis, although the thrombotic risk with IBD appears to wax and wane with disease severity. Because of the lack of high-quality evidence to guide management decisions, approaches to the prevention and treatment of thrombosis in patients with obesity or IBD are based on extrapolation from general guidelines for antithrombotic therapy. Obesity alters the pharmacokinetics of some anticoagulant drugs, and IBD patients present the added management challenge of having a high risk of gastrointestinal bleeding while taking anticoagulants. An extended duration of anticoagulant therapy is often recommended for obese or IBD patients with unprovoked venous thromboembolism unless there is a high risk of bleeding, although more data and better biomarkers are needed to determine whether anticoagulation can be safely stopped in a subset of IBD patients during remission of active disease. Most patients with obesity or IBD require thromboprophylaxis in conjunction with hospitalization or surgery, with adjustment of anticoagulant dosing in patients with severe obesity.

Abstract
PURPOSE Currently, development of pulmonary thromboembolism (PTE) after surgery is frequently being followed by legal action in Korea, as consequences may be fatal. In the current study, we assessed possible countermeasures that medical teams can take when faced with conflicting opinions on responsibility for PTE. METHODS A retrospective analysis of claims handled by the Supreme Court and subordinate courts, from 1999 to 2015, was performed. We analyzed the type of procedure, associated complications, and critical legal points from the recorded judgments along with any liability limitations on surgeons. RESULTS After reviewing cases between 1999 and 2015, a total of 18 cases were analyzed. There were no cases in which the surgeon was held accountable between 1999 and 2002. From 2003, there were instances of the surgeon being held accountable, with a peak of cases in 2013. Legal standards applied in judicial decision-making related to appropriate use of preventive measures, operation characteristics, doctor's reaction towards symptom occurrence, obligation of postoperative medical care, and duty of explanation. CONCLUSION The courts in Korea have changed their position from one of denying doctors' liability to one of enforcing responsibility for PTE. Surgeons are therefore being held responsible with greater frequency, depending on the details of the case. Lessons can be learnt from precedents that can be incorporated into medical education and training programs with the aim of reducing both major PTE complication rates and litigation costs.

Abstract
The laparoscopic approach to Roux-en-Y gastric bypass (RYGB) is a highly regarded and frequently used bariatric procedure. We review our experience with robotic approaches to RYGB. We hypothesized that the robotic approach is safe and may produce similar outcomes to previously reported laparoscopic surgery. We conducted our study at the University Hospital, USA. Data regarding RYGB procedures performed in 2006-2013 were retrospectively reviewed from a prospectively maintained, dedicated database. Procedures were categorized into three groups: laparoscopic, hybrid robotic (HR), and total robotic (TR). Patient characteristics, operative variables, and postoperative short- and long-term outcomes were compared between groups and to recently published larger laparoscopic series. Our study included 192 RYGB consecutive patients who underwent laparoscopic, HR, or TR surgery. Mean patient age, preoperative body mass index, and preoperative weight were 40.4 ± 9.3 years (range 22-64), 46. 2 ± 5.9 kg/m(2) (range 35-64), and 130. 3 ± 22.1 kg (range 76.7-193.4) respectively. Ninety-two patients (47.9 %) had undergone previous abdominal surgery. Mean operative time, estimated blood loss, and length of stay were 223.4 ± 39.2 min (range 130-338), 21.9 ± 18.8 mL (range 5-10), and 2.6 ± 1.1 days (range 2-15), respectively. There were 248 concomitant procedures such as upper endoscopy, cholecystectomy, etc., 7 revisional surgeries, and 2 conversions to open surgery. Intraoperative complications included one liver laceration and one bowel injury. There were two cases each of bowel obstruction, transfusions, and deep vein thrombosis/pulmonary embolus, but no deaths or anastomotic leaks. Early experience with TR approach for RYGB is safe, with similar outcomes to the laparoscopic approach.

Abstract
BACKGROUND Despite that pulmonary embolism (PE) is a feared complication after shoulder arthroplasty, little is known about its perioperative associated factors. MATERIALS AND METHODS We used the Nationwide Inpatient Sample to gather a sample of 422,372 patients who underwent shoulder arthroplasty between 2002 and 2011. This population was divided into 2 cohorts on the basis of those who experienced perioperative PE (0.25%) and those who did not. Demographics were compiled for both cohorts. Multivariable logistic regression analysis was used to account for confounding variables and to determine significant predictors of perioperative PE. RESULTS After adjusting for patient demographic and clinical variables in multivariable regression modeling, the top 4 independent predictors for PE were primary diagnosis of proximal humerus fracture, deficiency anemia, congestive heart failure, and chronic lung disease. Other pertinent risk factors included increasing age, obesity, fluid and electrolyte abnormalities, undergoing total shoulder arthroplasty rather than hemiarthroplasty, and subsequent days of postoperative care. CONCLUSIONS Knowledge of these factors might help in preoperative counseling and prove useful for implementation of quality improvement strategies to reduce the occurrence of PE. Surgeons may consider initiating thromboprophylaxis in patients with any of the aforementioned comorbidities.

Abstract
Bariatric surgical procedures are now a common method of obesity treatment with established effectiveness. Venous thromboembolism (VTE) events, which include deep vein thrombosis and pulmonary embolism, are an important source of postoperative morbidity and mortality among bariatric surgery patients. Due to an understanding of the frequency and seriousness of these complications, bariatric surgery patients typically receive some method of VTE prophylaxis with lower extremity compression, pharmacologic prophylaxis, or both. However, the optimal approach in these patients is unclear, with multiple open questions. In particular, strategies of adjusted-dose heparins, postdischarge anticoagulant prophylaxis, and the role of vena cava filters have been evaluated, but only to a limited extent. In contrast to other types of operations, the literature regarding VTE prophylaxis in bariatric surgery is notable for a dearth of prospective, randomized clinical trials, and current professional guidelines reflect the uncertainties in this literature. Herein, we summarize the available evidence after systematic review of the literature regarding approaches to VTE prevention in bariatric surgery. Identification of risk factors for VTE in the bariatric surgery population, analysis of the effectiveness of methods used for prophylaxis, and an overview of published guidelines are presented.

Abstract
Inferior vena cava (IVC) filters are commonly used in select high-risk patients for the prevention of pulmonary embolism. Potentially serious complications can arise from the use of IVC filters, including thrombosis of the filter itself and filter fragment embolization. This article discusses the utility of IVC filters and reviews the management of two cases of filter-related complications.
