RESUMO

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 ±â€Š10.1 years. The mean BMI reduction at the end of the follow-up was 15.5 ±â€Š4.2 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.

RESUMO

Roux-en-Y gastric bypass has been considered the gold standard bariatric procedure for decades. The surgical technique for Roux-en-Y gastric bypass and perioperative management for patients who undergo the procedure are still being improved for better clinical outcomes, shorter hospitalization, and faster return to normal activity. In the past 15 years there have been similar improvements and further development of novel surgical weight loss procedures. As data on other surgical alternatives emerge, the data need to be compared with Roux-en-Y gastric bypass to determine noninferiority. Further long-term investigations are needed to determine superiority of one bariatric procedure over another.

RESUMO

Bariatric surgery has emerged as the most effective means of achieving weight loss. Obesity surgery is a quickly expanding field. Laparoscopic vertical sleeve gastrectomy is a great option for patients because it is simple, exceedingly safe, has a fairly defined postoperative complication profile, and is as effective as more complex bariatric surgery options. Specific consideration of patients' comorbidities, assessment of surgeon's skill, and knowledge of preoperative, perioperative, and postoperative course is a must for all surgeons who wish to perform this procedure. If properly used, vertical sleeve gastrectomy is a powerful tool in combating obesity and its deleterious effects.

RESUMO

Single-anastomosis duodenal ileostomy with sleeve gastrectomy (SADI-S) is an important emerging procedure in bariatric surgery as an alternative to performing the Roux-en-Y gastric bypass (RYGB) or the Roux-en-Y duodenal switch. With this significant weight loss and low weight regain, SADI-S has low complication rates. SADI-S, because of its anatomic configuration, also does not increase ulcer risk in patients, with almost no ulcers observed. Because of the short common channel, malnutrition is a risk. Diabetes resolution is higher than with RYGB. Overall SADI-S is a safe and effective procedure for patients with higher body mass index and patients with diabetes.

RESUMO

Revisional bariatric surgery is a growing subset of all bariatric procedures. Although revisions can be associated with higher morbidity rates and less optimal outcomes than those seen with primary procedures, they can be safely performed, with excellent outcomes and improved quality of life for patients. Facility and familiarity with revisional principles and techniques are necessary components of bariatric surgical practice.

RESUMO

Type 2 diabetes mellitus (T2D) and associated comorbid medical conditions are leading causes of strain on the American health care system. There has been a synchronous rise of obesity to epidemic proportions. If poorly treated, T2D is a scourge for patients, leading to end-organ damage and early mortality. Although T2D is considered best managed with lifestyle modification, medical management, and pharmacotherapy, recent studies have confirmed the superiority of metabolic surgery to conventional treatment algorithms as a path to remission. Increasing access to metabolic surgery will continue to yield benefits to patient health and improve the macroeconomic health of the world.

RESUMO

The prevalence of noncommunicable diseases has increased dramatically in North America and throughout the world and is expected to continue increasing in coming years. Obesity has been linked to several types of cancers and is associated with increased morbidity and mortality following cancer diagnosis. Bariatric surgery has emerged as the prominent model to evaluate the effects of intentional weight loss on cancer incidence and outcomes. Current literature, comprising prospective cohort investigations, indicates site-specific reductions in cancer risk with select bariatric procedures. Future research is required to establish evidence-based indications for bariatric surgery in the context of cancer prevention.

RESUMO

Obesity is an independent risk factor for osteoarthritis due to mechanical and inflammatory factors. The gold-standard treatment of end-stage knee and hip osteoarthritis is total joint arthroplasty (TJA). Weight loss decreases progression of osteoarthritis and complications following TJA in patients with obesity. Bariatric surgery allows significant, sustained weight loss and comorbidity resolution in patients with morbid obesity. Existing data describing bariatric surgery on TJA outcomes are limited but suggest a benefit to bariatric surgery prior to TJA. Further studies are needed to determine optimal risk stratification, bariatric procedure selection, and timing of bariatric surgery relative to TJA.

RESUMO

Despite its important treatment implications for obesity and related comorbidities, bariatric surgery requires several behavioral changes that warrant comprehensive evaluation and support before and after surgery. This article outlines emerging scientific and anecdotal evidence for addiction transfer after bariatric surgery. Other common behavioral changes that impact adherence, weight loss, and psychiatric risk after surgery are also reviewed. Last, recommendations for presurgical psychological evaluation and postoperative support are provided.

RESUMO

Bariatric/metabolic surgery has emerged as an option for significant and durable weight loss in the treatment of clinically severe obesity; there is increasing demand for bariatric/metabolic surgery worldwide. New procedures have been developed and changed the face of modern bariatric surgery. Gastrointestinal metabolic surgery is a new treatment modality for obesity-related type 2 diabetes mellitus for patients with body mass index greater than 35 kg/m2. Providing safe bariatric/metabolic surgery, training qualified bariatric surgeons, and developing better techniques are important issues. This article discusses emerging procedures; a multitude of bariatric metabolic procedures enables surgeons to tailor treatment to patients' needs.

RESUMO

Intragastric balloon therapy is an endoluminal treatment of obesity that is indicated for patients with moderate obesity (body mass index, 30-35 kg/m2) who have failed to lose weight with lifestyle and medical management. Treatment duration ranges from 4 to 12 months, and percent total body weight loss ranges from 6% to 15% at the time of balloon removal. Adverse events, such as bowel obstruction or gastric perforation, are rare, and early balloon removal because of intolerance is the most common complication. Long-term data are lacking, although weight regain after balloon removal seems to be common.

RESUMO

OBJECTIVE: To examine epidemiologic, anthropometric and clinical variables associated with stress urinary incontinence in obese women, before and after bariatric surgery, and to identify predictive factors of stress urinary incontinence resolution. METHODS: Prospective observational study with women enrolled in a bariatric surgery program between 2015 and 2016. Patients were assessed prior to and 6 months after bariatric surgery using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Patient Global Impression of Improvement and the Visual Analogue Scale. Patient assessment also included physical examination and bladder stress tests. RESULTS: A total of 43 women completed the study. There was a 72.7% reduction in stress urinary incontinence (p=0.021). Predictive factors for preoperative diagnosis of stress urinary incontinence included age (p=0.024) and abdominal waist circumference (p=0.048). Urinary symptoms improved after weight loss, especially nocturia (p=0.001) and stress urinary incontinence (p=0.026). Menopause was the most significant predictive factor for persistence of stress urinary incontinence within six months of bariatric surgery (p=0.046). Self-reported outcomes and scores obtained in the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Patient Global Impression of Improvement and the Visual Analogue Scale were associated with significant improvement (p=0.012, p=0.025, and p=0.002 respectively). CONCLUSION: Older women with larger waist circumference have a higher risk of developing stress urinary incontinence prior to bariatric surgery. Menopausal women are highly prone to persistent stress urinary incontinence, even after weight loss. Weight loss achieved through bariatric surgery improved stress urinary incontinence symptoms and mitigated related impacts on quality of life in the vast majority of women.

RESUMO

The World Health Summit 2011 confirmed the epidemic-like occurrence of diabetes mellitus and obesity. In Germany, 62.7 % and 21.9 % of the population have a BMI of more than 25 kg/m² and more than 30 kg/m2, respectively. Currently, 10.5 obese people per 100 000 German inhabitants undergo bariatric surgery, while 86 and 114.8 per 100 000 in France and in Sweden, respectively, favor bariatric surgical interventions. AIM: By means of a scientific case report, the instructive case of a young patient with morbid obesity is illustrated based on 1) selective references from the medical literature and 2) insights from the daily clinical practice in the case-specific medical and perioperative management after successful surgery for malformation in his childhood and, thus, the limited therapeutic options of metabolic surgery. CASE REPORT (CASE-, DIAGNOSTIC-, AND TREATMENT-SPECIFIC ASPECTS): 35-year-old patient with morbid obesity. Medical history: Status after surgical intervention for gastroschisis as a newborn (surgery report not available). Clinical findings: Super obesity characterized by 234 kg and 174 cm (→ BMI: 77.3 kg/m²), hypogonadotrophic hypogonadism. Approach & course: · Initial treatment with gastric balloon followed by a weight reduction of 46 kg within the first 6 months; however, despite weight reduction, development of an insulin-dependent diabetes with insulin resistance from a diet-based diabetes;. · Repeat gastric balloon therapy for "bridging" but with no further weight reduction despite additional administration of GLP-1 analogues.. · Surgical intervention: Removal of the balloon - termination because of excessive adhesions to the liver and spleen as well as filiforme hepatic lesions (histopathology: liver hamartoma). Open surgery: extensive adhesiolysis because of previous pediatric surgery for gastroschisis, including associated non-rotation of the intestine with complete right-sided position of the intestine (left side: colon; right flexure: at infralienal position) prompting single-anastomosis duodeno-ileostomy (SADI)-procedure, leaving the stomach in situ with simultaneous cholecystectomy and herniotomy in sublay technique.. Outcome (early postoperative and mid- to long-term): The patient tolerated the intervention well. Postoperative course was uneventful with regard to mobilization, beginning of oral nutrition, and wound healing; there was a subsequent weight reduction due to a "common channel" of 250 cm. CONCLUSION: While the increase of obesity prevalence in adults has currently stopped, incidence in children and teenagers is rapidly rising. The consequence might be that children and young adults who have undergone bariatric surgery in childhood and adolescence can develop complications from these former interventions as adults. Therefore, it is reasonable to recommend follow-up investigations within specialized centers according to well-established standards. On the other hand, the increasing prevalence of obesity in childhood leads to the possibility that adults who underwent pediatric surgery because of embryonal malformations may require an appointment with a bariatric surgeon at some point. For these patients (as a representative example of the transition of care phenomenon), the risk of metabolic surgical intervention is increased; such operations require the appropriate knowledge and expertise of the bariatric surgeon on embryonal malformations and their approach by pediatric surgery.

RESUMO

Obesity is a major health problem with a prevalence that has tripled since 1976, affecting a large portion of the population across all ages. Bariatric surgery is currently considered as the most efficient and durable treatment in terms of weight loss and remission of long-term co-morbidities. The objective of this article is to describe briefly the different surgical options for patients with severe obesity and to report their effectiveness, as well as to provide primary care physicians with simple instructions, regarding initial management and the appropriate guidance of their patients to a specialized service.

RESUMO

ABSTRACT: Mass lesions in the brain encompass a wide range neoplastic and nonneoplastic entities. These can present as a diagnostic pitfall, with nonspecific, overlapping symptoms and similar appearances on radiology. They may cause death through varied mechanisms, either specific to the underlying pathophysiology or due to the space-occupying effect of the lesion. We report a case of fatal hemorrhagic cerebral pseudocyst, a rare mass lesion, associated with a cerebral varix, causing death in a morbidly obese individual. To the best of our knowledge, there is no previous documentation in the postmortem literature of this entity as a cause of death. This case aims to document this rare entity in the differential diagnosis of a tumor-like lesion in the brain, highlight the clinical difficulty in its assessment, and demonstrate an uncommon mechanism of death, of a mass lesion acting as a focus causing seizures, with resulting hypoxia due to effects of morbid obesity and heart failure.

RESUMO

Background: Robotic bariatric surgery (RBS) has increased in recent years. Many doubts continue to exist regarding its utility in terms of postoperative complications, costs and technical aspects. RBS has increased its number and shows a more technical challenge associated with more post-operative complications compared to primary bariatric surgery. We herein present a single institution experience and review to describe its utility in revisional surgery. Methods: A retrospective review of our experience and a review of the literature has been conducted to evaluate the impact of robotic revisional surgery in the bariatric field. Results: A total of 17 patients (5 female and 12 male) were operated on. Most frequent surgery was conversion of sleeve gastrectomy to gastric bypass (n=9). No leaks were found nor severe complications. A systematic review showed similar results including a decreased number for complications when performing robotic revisional surgery. Conclusions: Revisional robotic surgery shows better results compared to standard laparoscopic revisional bariatric surgery in terms of efficacy, safety and hospital stay. No differences were seen in rates of mortality, morbidity and reintervention between both approaches. We encourage surgeons to learn to perform the robotic technique as part of the process of democratization and standardization of bariatric surgery.

RESUMO

BACKGROUND: Obesity is an independent risk factor for the occurrence and development of diabetes. Patients with diabetes combined with obesity will face serious burdens such as increase in insulin resistance and difficulty in blood glucose control. As a safe, effective, economical, and simple intervention, Tuina is more acceptable to the public than drugs. The objective of this systematic evaluation and meta-analysis is to evaluate the efficacy and safety of Tuina for diabetes with obesity. METHODS: We will search the following electronic databases: PubMed, Embase, Cochrane Library, Web of science, Chinese National Knowledge Infrastructure (CNKI), Sino Med, Wanfang, Chinese Clinical Trial Registry System, China Biomedical Literature Database (CBM). The time limit for retrieving studies is from establishment to November 2020 for each database. Randomized controlled clinical trials related to Tuina intervention on diabetes with obesity will be included. Data synthesis, sensitivity analysis, subgroup analysis as well as the assessment of bias risk will be conducted by using Stata V.13.0 and Review manager 5.3 software. RESULTS: This study will provide a quantitative and standardized evaluation for the efficacy of Tuina therapy on diabetes with obesity. CONCLUSION: This systematic review and meta-analysis will provide the high-quality evidence of whether Tuina is an effective intervention for diabetes with obesity.

RESUMO

INTRODUCTION: Morbid obesity (body mass index > 40 kg/m2) is a risk factor for the development of left ventricular systolic dysfunction (LVSD) and can complicate the management of LVSD. Bariatric surgery is increasingly recognized as a safe and effective way to achieve marked weight loss, but studies on improving LVSD populations are limited. We retrospectively analyzed the first case of the Asia-Pacific region with morbid obesity and left ventricular ejection fraction (LVEF) < 50% who underwent bariatric surgery at our medical center. PATIENT CONCERNS: The patient was admitted to the hospital due to progressive weight gain for more than 10 years. The patient used to be in good health. One year before admission, the patient was hospitalized in another hospital due to shortness of breath. After the relevant examination, the patient was diagnosed with dilated cardiomyopathy. DIAGNOSIS: The body mass index of the patient was 45.9 kg/m2, and the patient was diagnosed with morbid obesity. He was diagnosed with dilated cardiomyopathy and cardiac function class IV in another hospital. After completing a preoperative examination, the patient was diagnosed with hyperuricemia, hyperlipidemia, fatty liver disease and severe sleep apnea. INTERVENTIONS: The patient successfully underwent laparoscopic sleeve gastrectomy plus jejunal bypass. OUTCOMES: Six months after the surgery, patient weight lost was 33.6 kg, and the LVEF increased from 31% to 55%. The cardiac function of the patient recovered from class IV to class I, and the patient's hyperuricemia, hyperlipidemia and sleep apnea were significantly improved. CONCLUSION: Bariatric surgery may be a safe and effective intervention for morbidly obese patients with LVSD. Bariatric surgery was associated with an improvement in LVEF. However, the specific mechanism still needs further study.

RESUMO

BACKGROUND: This study aimed to reevaluate the learning curve of laparoscopic Roux-en Y gastric bypass (LRYGB) in the modern era while considering a single surgeon's experience. METHODS: From the beginning of our LRYGB practice, all patients who met the regional criteria and underwent primary LRYGB were retrospectively enrolled. Patients with a body mass index (BMI) > 50 kg/m2 were excluded. Those who underwent surgery in 2016-17, 2018 and 2019 by a single surgeon with 10 + years of laparoscopic experience were assigned to groups A, B and C, respectively. The patient demographics and 30-day outcome data, including the operation time, length of stay (LOS), emergency room visits, readmission, and reoperation, were compared among the groups. RESULTS: One hundred and eight patients met the inclusion criteria; 36, 38, and 34 patients were assigned to groups A, B and C, respectively. There were no differences in age, sex distribution or common comorbidities among the groups; however, B had a lower BMI (35.1 kg/m2 vs. 37.0 kg/m2) and a higher rate of hypertension (44.7% vs. 22.2%) than group A. The operation time was markedly reduced (96.1 min and 114.9 min, p < 0.001), and the LOS was shortened (2.2 days and 2.9 days, p < 0.001) in group B compared to group A and remained stationary in group C, with no further reduction in 30-day complications. CONCLUSION: The learning process of LRYGB can be shortened to approximately 30 cases if conducted selectively by experienced laparoscopic surgeons. Further follow-up is required to verify the long-term safety and applicability in other patient subgroups.
