Many payors require an additional attempt at nonsurgical weight loss before approval of bariatric procedures. This study evaluates this requirement by characterizing the prior weight loss attempts (WLAs) undergone by bariatric surgery patients and correlating those attempts to postoperative weight loss outcomes. Number and duration of WLAs were obtained from a preoperative clinic assessment. Body mass index (BMI) and percentage of excess weight loss (%EWL) were used to assess weight loss. Kruskal-Wallis and Spearman Correlation tests were performed to analyze data using GraphPad Prism 6...

AIMS: To explicate the processes by which a patient's choice to undergo bariatric surgery is made to feel like a medical necessity, to explore the ways widespread societal stigmatization of weight and bariatric surgery shapes patient and provider discourse about surgery and to discuss patient rationalizations of the choice to have surgery. BACKGROUND: Severe obesity is currently highly stigmatized. Bariatric surgery has become an increasingly used option for individuals seeking to lose drastic amounts of weight...

Nonalcoholic fatty liver disease is becoming one of the most common causes of liver disease in the western world. The most significant risk factors are obesity and the metabolic syndrome for which bariatric surgery has been shown to be an effective treatment. However, the effects of bariatric surgery on nonalcoholic fatty liver disease, specifically liver fibrosis and cirrhosis, are not well established. We review published bariatric surgery outcomes with respect to nonalcoholic liver disease. On the basis of this review we suggest that bariatric surgery may provide a viable treatment option for the treatment of nonalcoholic fatty liver disease, including patients with fibrosis and compensated cirrhosis, and that this topic should be a target of future investigation...

Background: Weight-related stigma is reported frequently by higher body-weight patients in healthcare settings. Bariatric surgery triggers profound weight loss. This weight loss may therefore alleviate patients' experiences of weight-related stigma within healthcare settings. In non-clinical settings, weight-related stigma is associated with weight-inducing eating patterns. Dietary adherence is a major challenge after bariatric surgery. Objectives: (1) Evaluate the relationship between weight-related stigma and post-surgical dietary adherence; (2) understand if weight loss reduces weight-related stigma, thereby improving post-surgical dietary adherence; and (3) explore provider and patient perspectives on adherence and stigma in healthcare settings...

OBJECTIVE: To investigate the association between adverse surgical outcomes following bariatric surgery and proxy measures of vitamin D (VitD) status (season and latitude) in the Nationwide Inpatient Sample (NIS). BACKGROUND: Obesity is an independent risk factor for VitD deficiency (25(OH)D < 20 ng ml(-1)). VitD deficiency compounds the chronic inflammation of obesity, increasing the risk of adverse outcomes following bariatric surgery. Epidemiology has long used season and latitude as proxies for group VitD, as VitD status is largely determined by sun exposure, which is greatest during summer and at the Equator...

One of the most effective methods to tackle obesity and its related comorbidities is bariatric surgery. Polycystic ovary syndrome (PCOS) and endometrial hyperplasia (EH), which are associated with increased risk of endometrial carcinoma, have been identified as potentially new indications for bariatric surgery. PCOS is the most common endocrine disorder in women in the reproductive age and is associated with several components of the metabolic syndrome such as obesity, insulin resistance and hypertension. EH is a pre-cancerous condition which arises in the presence of chronic exposure to estrogen unopposed by progesterone such as both in PCOS and obesity...

BACKGROUND: Many studies using self-reported physical activity (PA) assessment tools have suggested there is an increase in PA after bariatric surgery. OBJECTIVES: Our aim was to assess PA and sedentary behavior before bariatric surgery and at 6 months after, using subjective and objective tools. SETTING: Bariatric surgery candidates were recruited from a single center. METHODS: Demographic data, medical history, current medications, and anthropometric measurements were recorded...

BACKGROUND: The reasons why some patients who begin the presurgical process for bariatric surgery fail to complete the procedure are understudied. Previous research implies that psychological factors play a role. OBJECTIVES: To examine whether scores from baseline psychological testing incrementally predict failure to proceed with bariatric surgery beyond demographic information in patients' medical charts and data derived from a clinical interview. SETTING: Cleveland Clinic Bariatric and Metabolic Institute...

BACKGROUND: Food cravings and consumption of craved foods after Roux-en-Y gastric bypass (RYGB) are poorly understood. Food cravings after bariatric surgery may explain why some patients fail to change eating behaviors after RYGB, and understanding these cravings may provide better information for nutritional counseling to either enhance weight loss or prevent weight regain. OBJECTIVES: To study cravings in RYGB patients and compare them with cholecystectomy (CC) control patients...

OBJECTIVE: The outcomes of patients undergoing band removal alone without an additional bariatric procedure after laparoscopic gastric banding are not well reported. We seek to close this gap in the literature. SETTING: Cantonal Hospital & University Teaching Hospital, Switzerland METHODS: In this retrospective study, we investigated 21 patients who underwent band removal with a mean follow-up of 63 months. Weight regain, co-morbidities, and quality of life were assessed...

INTRODUCTION: National guidelines for commissioning of body contouring surgery (BCS) following massive weight loss (MWL) in England were published in 2014. Nearly three-quarters of patients who have MWL seek BCS; however, access is known to vary according to the region. The aim of national guidelines was to standardise access. The purpose of this study was to determine implementation of the national guidelines by clinical commissioning groups (CCGs) in England. MATERIALS AND METHODS: A cross-sectional, web-based survey was sent to all CCG chairs in England...

BACKGROUND: Morbid obesity is associated with worse colorectal cancer (CRC) perioperative outcomes. The impact of bariatric surgery on these outcomes is unknown. METHODS: The National Inpatient Sample Database (2006-2012) was used to identify adults with prior bariatric surgery (divided into BMI ≤35 kg/m(2) and BMI >35 kg/m(2)) or morbid obesity that underwent CRC surgery. Main outcomes were mortality, surgical complications and health care utilization. RESULTS: There were 1813 patients with prior bariatric surgery and 22,552 morbidly obese patients that underwent CRC surgery between 2006 and 2012...

BACKGROUND: With over 110,000 bariatric operations performed in the United States annually, it is important to understand the biochemical abnormalities causing endocrine dysfunction associated with these procedures. Here we compare 2 malabsorptive procedures, duodenal switch and Roux-en-Y gastric bypass, to determine the role malabsorption plays in secondary hyperparathyroidism in this population. METHODS: Data from all super-obese patients undergoing duodenal switch or Roux-en-Y gastric bypass between August 2002 and October 2005 were prospectively collected...

BACKGROUND: Impulsivity is a multifaceted construct and constitutes a common risk factor for a range of behaviors associated with poor self-control (e.g., substance use or binge eating). The short form of the Barratt Impulsiveness Scale (BIS-15) measures impulsive behaviors related to attentional (inability to focus attention or concentrate), motor (acting without thinking), and non-planning (lack of future orientation or forethought) impulsivity. Eating-related measures appear to be particularly related to attentional and motor impulsivity and recent findings suggest that interactive effects between these two facets may play a role in eating- and weight-regulation...

PURPOSE: Single anastomosis sleeve ileal bypass (SASI) procedure appears as a new metabolic and bariatric surgery based on Santoro's operation, in which a sleeve gastrectomy is followed by a side-to-side gastroileal anastomosis. The study is aimed to evaluate the short-term outcomes of laparoscopic single anastomosis sleeve ileal bypass with respect to postoperative weight loss and metabolic and nutritional effects on patients. METHODS: Forty-five morbidly obese patients with a mean age of 31...

Semicarbazide-sensitive amine oxidase (SSAO), identical to primary amine oxidase or vascular adhesion protein-1, is a membrane enzyme that generates hydrogen peroxide. SSAO is highly expressed at the adipocyte surface, and its plasma levels increase with type 2 diabetes. Since visceral adipose tissue (AT) is more tightly associated with obesity complications than subcutaneous (SC) abdominal fat, we compared SSAO activity in plasma and 4 distinct AT locations in 48 severely obese women (body mass index (BMI), averaging 54 ± 11 kg/m(2)), with or without a dysmetabolic profile...

Bariatric surgery, initially intended as a weight-loss procedure, is superior to standard lifestyle intervention and pharmacological therapy for type 2 diabetes in obese individuals. Intensive medical management of hyperglycemia is associated with improved microvascular outcomes. Whether or not the reduction in hyperglycemia observed after bariatric surgery translates to improved microvascular outcomes is yet to be determined. There is substantial heterogeneity in the data relating to the impact of bariatric surgery on diabetic retinopathy (DR), the most common microvascular complication of diabetes...

BACKGROUND AND AIMS: Unsatisfactory weight loss after gastric bypass or sleeve gastrectomy in super-obese patients (body mass index > 50) is a growing concern. Biliopancreatic diversion with duodenal switch results in greater weight loss, but is technically challenging to perform, especially as a laparoscopic procedure (Lap-DS). The aim of this study was to compare perioperative outcomes of Lap-DS and the corresponding open procedure (O-DS) in Sweden. MATERIAL AND METHODS: The data source was a nationwide cohort from the Scandinavian Obesity Surgery Registry and 317 biliopancreatic diversion with duodenal switch patients (mean body mass index = 56...
