PURPOSE: Although bariatric surgery fosters heightened excess weight loss values, nutritional deficiencies are prominent; one of the most common being iron deficiency anemia. The purpose is to elucidate the frequency of anemia in Roux-en-Y gastric bypass and sleeve gastrectomy subjects. MATERIALS AND METHODS: A retrospective analysis was conducted, in subjects (N = 100) diagnosed with type II diabetes who were randomized into sleeve gastrectomy or Roux-en-Y gastric bypass and intensive medical therapy...

BACKGROUND: Morbid obesity is a state of insulin resistance combined with excess of visceral fat, which contributes to the development of metabolic syndrome (MetS). Nonsurgical treatment of obesity usually improves MetS, but there is no ultimate resolution and weight regain is common. Surgical options like Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) result in a significant and sustained weight loss accompanied by improvement of MetS. The aim of this study was to compare the weight loss and improvement of MetS parameters between degree II and III obese patients with MetS undergoing RYGB or SG in a period of 12 months...

INTRODUCTION: Over the last few decades, the prevalence of obesity has increased dramatically. This increase has been mirrored by a rise in the risk of a number of health conditions, including hypertension, diabetes and chronic kidney disease. Although the weight loss following bariatric surgery has been shown to relieve the severity of diabetes and reduce hypertension, the effect on renal function has been less extensively evaluated. OBJECTIVE: The aims of the present study were to: (i) compare the estimated glomerular filtration rate (eGFR, using the MDRD and CKD-EPI equations) and the calculated glomerular filtration rate (using the 24-hour urine volume) with the measured glomerular filtration rate (mGFR) assessed with the plasma iohexol clearance method in severely obese patients, and (ii) evaluate the effect of weight loss on the mGFR 6 months after bariatric surgery...

BACKGROUND: Despite a higher rate of obesity in rural populations, there is a 23% decrease in performed bariatric procedures. The influence of a rural environment on surgical outcomes and treatment efficacy is unknown. METHODS: We retrospectively reviewed all bariatric surgeries performed in a large university hospital in West Virginia from September 2012 to September 2014. Patients were categorized based on their rural-urban commuting area codes. Subject demographic characteristics, insurance provider, type of surgery, completion of program, preoperative body mass index (BMI), percent excess weight loss (%EWL), and percent total weight loss (%TWL) at 6 and 12 months postoperatively, and follow-up appointment attendance were collected...

BACKGROUND: Evidence about the impact of psychological factors on weight loss after bariatric surgery is scarce. This study explores whether patients' preoperative estimate of target weight influences actual weight loss for different types of bariatric procedures. METHODS: Patients eligible for bariatric surgery were instructed twice on how to calculate their expected target weight. They were divided into three groups based on their percentage excess weight loss (%EWL) and percentage total body weight loss (%TBWL)...

Gastroesophageal reflux disease (GERD) is a common disorder that has a well-established connection with obesity. To ameliorate the morbidity associated with obesity, bariatric procedures have become an established pathway to accomplish sustained weight loss. In some procedures, such as with the Roux-en-Y gastric bypass surgery, weight loss is also accompanied by the resolution of GERD symptoms. However, other popular bariatric surgeries, such as the sleeve gastrectomy, have a controversial impact on their effect on reflux...

Middle-aged women are at a higher risk of being obese. We examined the trajectory of post-surgical % total weight loss (%TWL) among middle-aged female bariatric patients. We fitted sequential generalized estimating equations models to analyze a sample of women who received bariatric surgery in 1995-2012, aged 40-65 years at the time of surgery (N = 158,292) whose pre-operative body mass index (BMI) was ≥ 30 kg/m(2) in the Bariatric Outcomes Longitudinal Database. The %TWL computed by 100% × (pre-surgery BMI - post-surgery BMI) / pre-surgery BMI showed different trajectories depending on type of surgery...

Diet, exercise, cognitive behavioral therapy and pharmacotherapy are some of the means of assisting patients to lose weight, with bariatric surgery being the most effective. Over the last two decades, the increased awareness of the systemic benefits of bariatric surgery, as well as the improved safety and the wider use of the laparoscopic approach, has made bariatric surgery flourish. In the United Kingdom, the adjustable gastric band (10%), vertical sleeve gastrectomy (37%) and Roux-en-Y gastric bypass (45%) are the three most common procedures...

BACKGROUND: It has been proven that bariatric surgery affects weight loss. Patients with morbid obesity have a significantly lower quality of life (QOL) and body image compared with the general population. OBJECTIVE: To evaluate QOL, body image, and general self-efficacy (GSE) in patients with morbid obesity undergoing bariatric surgery within clinical parameters. SETTINGS: Monocentric, prospective, longitudinal cohort study. METHODS: Patients completed the short form 36 (SF-36) for QOL, body image questionnaire, and GSE scale 3 times: before surgery and within 6 months and 24 months after surgery...

As lifestyle and diet patterns have become westernized in East Asia, the prevalence of obesity has rapidly increased. Bariatric surgeries, such as Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and laparoscopic adjustable gastric banding (LAGB), are considered the first-line treatment option in patients with severe obesity. However, postoperative complications have increased and the proper management of these complications, including the use of endoscopic procedures, has become important. The most serious complications, such as leaks and fistulas, can be treated with endoscopic stent placement and injection of fibrin glue, and a novel full-thickness closure over-the-scope clip (OTSC) has been used for treatment of postoperative leaks...

INTRODUCTION: In 2013, a worldwide bariatric surgery survey showed that laparoscopic adjustable gastric banding (LAGB) has been abandoned in favor of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-y gastric bypass (LRYGBP). PURPOSE: The aim of this study was to compare results of LRYGBP and LSG performed as a revisional procedure after LAGB. MATERIALS AND METHODS: All patients converted from LAGB to LSG or to LRYGBP from January 2007 to December 2011 were included in the study...

BACKGROUND: Several reviews have recently detailed the beneficial effects of weight loss surgery for kidney function. However, these studies have a number of limitations, including small sample size, few done in chronic kidney disease (CKD) stages 3 and 4, and many not including the main bariatric surgery procedures used in the United States today. STUDY DESIGN: This was an observational retrospective cohort study comparing propensity score-matched bariatric surgery patients and nonsurgery control patients who were referred for, but did not have, surgery...

Bariatric surgeries, such as Roux-en-Y gastric bypass and vertical sleeve gastrectomy, produce significant and durable weight loss in both humans and rodents. Recently, these surgical interventions have also been termed metabolic surgery because they result in profound metabolic improvements that often surpass the expected improvement due to body weight loss alone. In this review we focus on the weight-loss independent effects of bariatric surgery, which encompass energy expenditure and macronutrient preference, the luminal composition of the gut (i...

This review examines weight loss and accompanying improvements in obesity-related comorbidities produced by intensive lifestyle intervention, pharmacotherapy, and bariatric surgery. Obese individuals lose approximately 6 to 8 kg (approximately 6% to 8% of initial weight) with 6 months of participation in a high-intensity lifestyle intervention (≥ 14 treatment visits) consisting of diet, physical activity, and behavior therapy. Such losses reduce progression to type 2 diabetes in at-risk people and decrease blood pressure and triglyceride levels...

BACKGROUND: Robust data on quality of life (QoL) after different techniques of bariatric surgery are sparse. This RCT compared excess weight loss (EWL) and QoL after sleeve gastrectomy versus Roux-en-Y gastric bypass (RYGB). METHODS: Obese patients were assigned randomly to RYGB or sleeve gastrectomy. The primary outcome measure was EWL. Secondary outcomes included QoL, co-morbidity, adverse events, vitamin and glycolipid status. QoL was assessed before and annually after surgery, using the Moorehead-Ardelt Quality of Life Questionnaire II (M-A-QoLQII) and Gastrointestinal Quality of Life Index (GIQLI)...

Obesity is one of the most important public health conditions worldwide. Bariatric surgery for severe obesity is an effective treatment that results in the improvement and remission of many obesity-related comorbidities, as well as providing sustained weight loss and improvement in quality of life. Contemporary bariatric operations include Roux-en-Y gastric bypass, sleeve gastrectomy, adjustable gastric band and the duodenal switch. The vast majority of these procedures are now performed using laparoscopic technique, the main advantages of which include rapid recovery, the reduction of postoperative pain and the reduction of wound-related complications, compared with open surgery...
