INTRODUCTION Obesity is related with higher incidence of gastroesophageal reflux disease. Antireflux surgery has inadequate results when associated with obesity, due to migration and/or subsequent disruption of antireflux wrap. Gastric bypass, meanwhile, provides good control of gastroesophageal reflux. OBJECTIVE To evaluate the technical difficulty in performing gastric bypass in patient...

Roux-en-Y gastric bypass (RYGB) surgery is a very successful option for the management of obesity, and our understanding of how this intervention mediates sustained weight loss continues to grow. Controversy exists regarding whether bariatric surgical procedures such as RYGB may modulate food preferences of individuals, in particular, reducing appetitive and consummatory behaviour toward dietar...

As the incidence of obesity increases, laparoscopic Roux-en-Y gastric bypass (REYGB) surgery has become a surgical option for many patients. Although the laparoscopic Roux-en Y procedure has been shown to reduce weight and improve diabetes, hyperlipidemia, hypertension and sleep apnea, it is not without significant risks, as more than 10% of patients who undergo this procedure have postoperativ...

INTRODUCTION The first survey of bariatric surgery in Poland was published in 2007. New trends are observed worldwide, and there is a current need to investigate the status of bariatric surgery in Polish institutions. This survey was initiated to gain an overview of Polish bariatric surgery during 2007-2014. AIM To analyze the number and types of bariatric procedures performed in Polish insti...

INTRODUCTION Laparoscopic Roux-en-Y gastric bypass is a bariatric operation that is effective for long-term weight loss. Although rare, one serious complication is an internal hernia through Petersen's space, which may result in bowel strangulation. Although the incidence of internal hernia can be reduced through closing the Petersen's defect, it does not eliminate the risk. This case describes...

Currently, the most effective therapy for the treatment of morbid obesity to induce significant and maintained body weight loss with a proven mortality benefit is bariatric surgery. Consequently, there has been a steady rise in the number of bariatric operations done worldwide in recent years with the Roux-en-Y gastric bypass (gastric bypass) being the most commonly performed operation. Against...

OBJECTIVE To compare two bariatric surgical principles with regard to effects on blood pressure and salt intake. BACKGROUND In most patients bariatric surgery induces a sustained weight loss and a reduced cardiovascular risk profile but the long-term effect on blood pressure is uncertain. METHODS Cohort study with data from the prospective, controlled Swedish Obese Subjects (SOS) study invo...

OBJECTIVE To investigate changes in neural activation and desire to eat in response to appetitive cues from pre- to postbariatric surgery for obesity. BACKGROUND Roux-en-Y gastric bypass (RYGB) is the most common bariatric procedure. However, the mechanisms of action in RYGB are not well understood. A significant proportion of the resulting reduction in caloric intake is unaccounted for by th...

BACKGROUND We have read the letter by Bhoyrul et al. in response to our recently published article "Safety and effectiveness of bariatric surgery: Roux-en-Y gastric bypass is superior to gastric banding in the management of morbidly obese patients". We strongly disagree with the content of the letter. RESULTS AND DISCUSSION Bhoyrul et al. base their letter mostly on low level evidence such as...

Background. Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been shown to be an effective treatment for type 2 diabetes mellitus (T2DM) in patients with morbid obesity. However, it is unclear just how effective the LRYGB procedure is on T2DM for patients with BMI less than 35 kg/m(2). We report one obese patient with T2DM who did not meet the current NIH criteria for morbid obesity surgery. T...
