BACKGROUND Due to the increased prevalence of obesity in many countries, the number of bariatric surgeries is increasing. They are considered the most effective treatment for obesity. In the postoperative there may be difficulties with the quality of alimentation, tolerance to various types of food, as well as vomiting and regurgitation. Few surveys are available to assess these difficulties in...

Obesity, and the comorbidities associated with it, have become endemic within society. Roux-en-Y gastric bypass (RYGB) surgery is an increasingly common procedure with medical and cosmetic benefits (Li et al., 2014) [1]. However, as the case volume increases so do the rate of uncommon complications and it is imperative for surgeons to be aware of management guidelines of these complications. We...

HYPOTHESIS Mucosal cytokines may be involved in the process of gastric bacterial contamination that may occur after Roux-en-Y bypass for morbid obesity in both gastric chambers, with inflammation and gastritis mostly in the excluded stomach. DESIGN A prospective observational study in a homogeneous population with nonspecific complaints. SETTING Outpatient clinic of a large, public, academi...

BACKGROUND To review our experience with early jejunojejunostomy obstruction (JJO) at a large academic teaching hospital and provide a management algorithm. Early JJO is a known and often overlooked complication of laparoscopic Roux-en-Y gastric bypass. METHODS From 2003 to 2007, 1097 patients underwent laparoscopic Roux-en-Y gastric bypass at our institution. Data, including patient demograp...

Conventional laparoscopic Roux-en-Y gastric bypass (LRYGB) is a gold standard for bariatric surgery, but the procedure requires five to seven incisions for placement of multiple trocars and thus may produce less-than-ideal cosmetic results. We have developed a new approach, single-incision transumbilical LRYGB (SITU-LRYGB) to treat morbid obesity. We compared the surgical results and patient sa...

INTRODUCTION Bariatric surgery has become increasingly more recommended for the treatment of morbidly obese individuals for whom it is possible to identify co-morbidities other than alterations in pulmonary function. The objective of this study was to evaluate the effects of conventional chest physiotherapy (CCP) and of conventional physiotherapy associated with transcutaneous electrical diaphr...

CONTEXT Hypertension is a common disorder in general practice and has a widely known association with type 2 diabetes mellitus. Low adhesion to clinical treatment may lead to poor results. Obesity surgery can bring early and relevant resolution rates of both morbidities. OBJECTIVE To describe hypertension evolution after Roux-en-Y gastric bypass in patients with type 2 diabetes mellitus. ME...

OBJECTIVES The assessment of nutritional intake before and after bariatric surgery assists in identifying eating disorders, nutritional deficiencies and weight loss/maintenance. The 7-day record is the gold standard for such an assessment and is interpreted using specialized software. This study sought to compare the Virtual Nutri Plus® and Dietpro 5i® software systems in assessing nutrient int...

BACKGROUND Bariatric operations may alter esophageal motility; however, there is a paucity of studies of the esophageal motility with high resolution manometry. AIM To study patients after Roux-en-Y gastric bypass for morbid obesity with high resolution motility. METHODS Were included 18 asymptomatic patients (17 women, mean age 53 years) after undergoing to Roux-en-Y gastric bypass for mor...

OBJECTIVES This study aimed to determine whether advanced age or sex was predictive of adverse outcomes after Roux-en-Y gastric bypass. METHODS The Pennsylvania State Discharge Database was searched for records of morbidly obese patients who underwent Roux-en-Y gastric bypass. The SASs MIXED Procedure was used to test whether mortality alone or adverse outcomes (postoperative complications, n...
