Weight Loss after Roux-en-Y Gastric Bypass in Obese Patients Heterozygous for MC4R Mutations

Background  

Heterozygous mutations in melanocortin-4 receptor (MC4R) are the most frequent genetic cause of obesity. Bariatric surgery is a successful treatment for severe obesity. The mechanisms of weight loss after bariatric surgery are not well understood.     

The impact of obesity on outcomes of laparoscopic surgery for colorectal cancer in Asians

Background  

The influence of obesity on surgical outcomes after laparoscopic colorectal surgery in Asian patients is unclear. The aim of this study was to evaluate the feasibility and safety of laparoscopic surgery in obese Asian patients with colorectal cancer.     

Prompt Reduction in Use of Medications for Comorbid Conditions After Bariatric Surgery

Background  

Bariatric surgery leads to weight loss, but it is unclear whether surgery reduces conditions associated with obesity. We explored this by assessing the change in use of medications to treat diabetes mellitus, hypertension, and hyperlipidemia in the year following surgery.     

The Fast Food and Obesity Link: Consumption Patterns and Severity of Obesity

Background  

Rates of extreme forms of obesity are rapidly rising, as is the use of bariatric surgery for its treatment. The aim of the present study was to examine selected behavioral factors associated with severity of obesity among preoperative bariatric surgery patients in the San Antonio area, focusing specifically on the effects of fast food consumption.     

Combination of Bypassing Stomach and Vagus Dissection in High-Fat Diet-Induced Obese Rats—A Long-Term Investigation

Background  

Gastric bypass is the most popular technique in obesity therapy. We hypothesize that bypass surgery can help to control the body weight in morbid obesity, and this effect can be enhanced by vagus dissection.     

Nutritional Intake and Prevalence of Nutritional Deficiencies Prior to Surgery in a Spanish Morbidly Obese Population

Background  

The prevalence of obesity in Spain is on the rise with the consequent increase in bariatric surgery. Studies in non-Mediterranean populations have shown that micronutrient deficits are present before surgery. However, there is no data on this topic in a Spanish population.     

Asymptomatic Sleep-disordered Breathing in Premenopausal Women Awaiting Bariatric Surgery

Background  

There is a strong association between sleep-disordered breathing (SDB) and obesity. However, there are no studies addressed to determining the prevalence of SDB in morbidly obese premenopausal women, the most frequent group of patients requiring bariatric surgery. To evaluate the prevalence and characteristics of sleep apnea-hypopnea syndrome (SAHS) and obesity hypoventilation syndrome (OHS) in morbidly obese pre-menopausal women included in a program of bariatric surgery.     

Technique of open laparoscopy for supramesocolic surgery in obese patients

Background  

Incidence of obesity and related diseases are increasing in the world. Visceral surgeons are more often confronted with laparoscopic surgery in obese patients. Besides validated surgery procedures, such as cholecystectomy and gastroesophageal reflux surgery, bariatric procedures are increasingly performed. In obese patients, the thickness of adipose panicle makes open laparoscopy hazardous.     

Health-related Quality of Life in Adult Patients with Morbid Obesity Coming for Bariatric Surgery

Background  

Obesity has become a major health issue not only in the West but also in Asia. Morbid obesity can lead to much comorbidity and can markedly interfere with quality of life. The aim of this study was to compare the health-related quality of life (HRQL) between patients with morbid obesity coming for bariatric surgery and the healthy population in Taiwan.     

Confirmatory Factor Analysis of the Beck Depression Inventory in Obese Individuals Seeking Surgery

Background  

The Beck Depression Inventory (BDI) is frequently employed as measure of depression in studies of obesity. The aim of the study was to assess the factorial structure of the BDI in obese patients prior to bariatric surgery.     

Nutritional Deficiencies in Bariatric Surgery Candidates

Background  

To assess the prevalence of nutritional deficiencies amongst people who suffer from morbid obesity and are candidates for bariatric surgery and to evaluate the relations between pre-operative nutritional deficiencies and demographic data and co-morbidities.     

Bariatric Surgery: 1-Year Weight Loss Outcomes in Patients with Bipolar and Other Psychiatric Disorders

Background  

Bariatric surgery is the most effective obesity treatment in terms of weight loss and resolution of comorbidities. Roux-en-Y bypass surgery achieves weight loss of 60% to 70% excess body weight in most morbidly obese individuals. Patients with psychological disorders are reported to have less optimal results and those with bipolar, possibly worse.     

Public Perception of LESS Surgery and NOTES

Introduction  

This study was undertaken to determine public attitudes toward laparoendoscopic single-site (LESS) surgery and natural orifice transluminal endoscopic surgery (NOTES) and to determine how they are impacted by age, gender, and obesity.     

Apelin Levels Are Increased in Morbidly Obese Subjects with Type 2 Diabetes Mellitus

Background  

The physiological role of apelin in obesity and diabetes remains unclear. Although apelin has been studied in persons with different conditions, no studies have yet examined the joint influence of obesity and diabetes on apelin levels. We measured the changes in apelin levels in morbidly obese subjects, with and without diabetes, and in the inverse situation of improvement in carbohydrate metabolism as a result of bariatric surgery.     

Metabolic surgery—principles and current concepts

Introduction  

In the almost six decades of bariatric surgery, a variety of surgical approaches to treating morbid obesity have been developed.     

High-Volume Bariatric Surgery in a Single Center: Safety, Quality, Cost-Efficacy and Teaching Aspects in 2,000 Consecutive Cases

Background  

Obesity surgery is the most effective treatment for morbid obesity and the fastest growing area in surgery. Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the gold standard procedure in many countries. Optimization of the treatment process is important in order to keep the morbidity rate down and cost of treatment as low as possible.     

Diabetic and bariatric surgery: A review of the recent trends

Introduction  

Bariatric surgery is currently the most effective treatment for diabetes associated with morbid obesity.     

Physical Fitness in Morbidly Obese Patients: Effect of Gastric Bypass Surgery and Exercise Training

Background  

There is a growing consensus that bariatric surgery is currently the most efficacious and long-term treatment for clinically severe obesity. However, it remains to be determined whether poor physical fitness, an important characteristic of these patients, improves as well. The purpose of this pilot study is to investigate the effect of gastric bypass surgery on physical fitness and to determine if an exercise program in the first 4 months is beneficial.     

Depletion of Serum Carotenoid and Other Fat-Soluble Vitamin Concentrations following Obesity Surgery

Background  

Obesity constitutes a growing health problem, and surgical treatment of severe obesity is increasingly used. Nutrient deficiencies are common following bariatric surgery and the evidence indicates a progressive increase in the incidence and severity of the deficiency of certain vitamins and related clinical conditions. Because of the potential role of carotenoids in disease prevention, our aim was to assess the carotenoid status in candidates for obesity surgery and the time-course changes following two bariatric procedures.     

The Utility of the Beck Depression Inventory in a Bariatric Surgery Population

Background  

The Beck Depression Inventory (BDI) is commonly used in bariatric surgery psychological assessments. However, several items may be measuring physical consequences of obesity (e.g., sleep disturbance, chronic pain, or sexual dysfunction) rather than depressive symptoms.
