Patients undergoing bariatric surgery lose substantial weight (> or = 50% excess weight loss [EWL]), but an estimated 20 per cent fail to achieve this goal. Our objective was to identify behavioral predictors of weight loss after laparoscopic Roux-en-Y gastric bypass. We retrospectively surveyed 148 patients using validated instruments for factors predictive of weight loss. Success was defined ...

BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a common bariatric procedure that has several advantages over Roux-en-Y gastric bypass, but data on the effectiveness of this procedure on metabolic syndrome have rarely been reported. METHODS This case control study compared the incidence of low grade systemic inflammation, insulin resistance, anthropometrics, lipid disturbances, and metabo...

In expert hands, laparoscopic gastric bypass (LGB) is associated with reduced morbidity and mortality compared with open bariatric surgery. The purpose of our study was to determine whether or not the results of LGB have been realized in the general US population. We used data from the nationwide inpatient sample to define differences in outcomes after LGB versus open techniques (OGB). We calcu...

OBJECTIVE To describe early and late fetal growth in pregnancies conceived after gastric bypass surgery in relation to time from surgery to conception of pregnancy. METHODS National cohort study on 387 Danish women, who had laparoscopic or open gastric bypass surgery prior to a singleton pregnancy in which first trimester screening was performed between January 2008 and June 2011. Data were d...

A recent gastric bypass can mask the symptoms of an acute abdomen. Physical examination is generally unreliable and subtle clinical symptoms or signs should alert clinicians to a significant postoperative problem. In morbidly obese patients, the presence of overt peritoneal findings is usually ominous, leading to sepsis, organ failure and death. We report a case of ruptured appendicitis followi...

INTRODUCTION The major goal of surgical treatment in morbid obesity is to decrease morbidity and mortality associated with excess weight. In this sense, the main factors of death are cardiovascular disease and metabolic syndrome. The objective of this study is to evaluate the effects of gastric bypass on cardiovascular risk estimation in patients after bariatric surgery. MATERIAL AND METHODS ...

BACKGROUND Patients with a body mass index (BMI) < 35 kg/m(2) who are obese, have uncontrolled co-morbidities, and have tried to lose weight with no success do not meet the "traditional" criteria for obesity surgery, and no other treatment is being offered to them. METHODS A total of 37 obese patients (30 women and 7 men) had been undergoing clinical treatment with no resolution or improvemen...

OBJECTIVE Gastric bypass operations are common and severely obese patients are prone to arrhythmias, particularly atrial fibrillation. Intraoperative ventricular arrhythmias during bariatric surgery have not been reported previously. CASE REPORT A 35-year-old, severely obese, diabetic woman with no other prior medical history underwent thorough preoperative cardiovascular evaluation before ha...

The incidence of morbid obesity is increasing and has led to an Background: increase in bariatric procedures and previous studies have shown that 71% of these patients suffer from obstructive sleep apnea (OSA). Patients with OSA have a higher rate of postoperative complications. We investigated if patients with OSA undergoing laparoscopic gastric bypass surgery have an increased risk of postope...
