Long-term evaluation of patients with BMI = 50kg/m2 who underwent Bariatric Surgery.

Purpose: to determine the risks and benefits of bariatric surgery in patients with super obesity (SO) in comparison with obesity grades II and III.

Methods: retrospective cohort that included a study group of 178 patients with SO and a control group of 181 patients with BMI 35-49.9Kg/m2.

Cholecystectomy Concomitant with Bariatric Surgery: Safety and Metabolic Effects.

Background: Obesity and fast weight loss in the postoperative period of bariatric surgery increase significantly the risk of cholelithiasis. Moreover, emerging evidence has pointed out the role of bile acids as possible metabolism and weight loss enhancers. This study aims to analyze the influence of cholecystectomy (CL) concomitant with bariatric surgery on weight loss, metabolic repercussions, and postoperative morbidity.

Surgical site infection in bariatric surgery: results of a care bundle.

Objective: to present a descriptive analysis of the results of a care bundle applied to obese patients submitted to bariatric surgery, regarding infection control.

Methods: a care bundle was designed to control surgical site infection (SSI) rates in patients undergoing bariatric surgery. The bundle included smoking cessation, bathing with 4% chlorhexidine two hours before surgery, cefazolin (2g bolus) in anesthetic induction associated with a continuous infusion of the same drug at a dose of 1g over a two-hour period, appropriate trichotomy, glycemic control, supplemental oxygen, normothermia, intraspinal morphine for the relief of pain, and sterile dressing removal 48 hours after surgery.

Bariatric surgery and the coronary artery calcium score.

Objective: to investigate the impact of bariatric surgery on the coronary artery calcium score (CACS), and to establish predictors of progression of this score in patients with obesity.

Methods: prospective study that evaluated 18 obese patients before and after bariatric surgery. All patients were submitted to computed tomography scans and blood tests (total cholesterol, LDL, HDL, triglycerides, fasting plasma glucose, A1C, insulin, serum calcium, C-peptide and C-Reactive Protein) in order to determine CACS and Framingham risk score (FRS).

Predictors of poor follow-up after bariatric surgery.

Objective: to identify predictive factors of loss of follow-up of patients submitted to Roux-en-Y gastric bypass and sleeve gastrectomy in a 48-month period.

Methods: we conducted a retrospective, cohort study from January 2010 to December 2012. We analyzed thirteen variables and compared them to loss of follow-up.

A Screening Study of Potential Carcinogen Biomarkers After Surgical Treatment of Obesity.

Background: Obesity has been associated with the development of various types of cancer. Biomarker studies may provide molecular level knowledge of the factors involved in this association, improving clinical practice through new methods of prevention and treatment.

Purpose: The present study aimed to analyze proteins found in the plasma of obese patients prior to and 6 months after bariatric surgery, using body mass index (BMI) and percentage total weight loss (%TWL) to evaluate, in a prospective manner, the effects of weight loss on the regulation of proteins related to the appearance of tumors.

SURGICAL TREATMENT OF SEVERE OBESITY IN TEENS: LATE RESULTS.

Background: In children is estimated that the prevalence of overweight and obesity has increased up to five times in developed countries and up to four in developing countries. In Brazil, the proportion of children and adolescents who are overweight also increased from approximately 4.1% to 13.

ANTIBIOTIC PROPHYLAXIS IN BARIATRIC SURGERY: a continuous infusion of cefazolin versus ampicillin/sulbactam and ertapenem.

Background: The incidence of surgical site infection in bariatric patients is significant and the current recommendations for antibiotic prophylaxis are sometimes inadequate. Objective: The aim of this study was to analyze the effect of three prophylactic antibiotic regimens on the incidence of surgical site infection.

Methods: A prospective, cross-sectional study was conducted between January 2009 and January 2013 in which 896 Roux-en-Y gastric bypasses were performed to treat obesity.

Revision surgery for treatment of weight regain after Roux-en-Y gastric bypass.

Background: This study aims to evaluate results on revision surgery for weight regain after gastric bypass, based on surgical technique and follow-up.

Methods: This study is a retrospective analysis of 29 patients who presented weight regain on follow-up after more than 5 years, divided into four groups according to revision surgery type: group 1 (n = 9) includes patients who underwent an increase in the length of the alimentary limb to 200 cm; group 2 (n = 13) are patients who underwent an increase in the length of the alimentary limb and placing of a silicon ring; group 3 (n = 2) are patients who underwent an increase in the length of the alimentary limb and gastric plication, and group 4 (n = 5) are patients who underwent gastric plication and placing of a silicon ring.

Results: The average preoperative weight before revision surgery was 117.

Gastrobronchial fistula as a rare complication of gastroplasty for obesity: a report of two cases.

Gastrobronchial fistula is a rare condition as a complication following bariatric surgery. The management of this condition requires the active participation of a pulmonologist, who should be familiar with aspects of the main types of bariatric surgery. Herein, we report the cases of two patients who presented recurrent subphrenic and lung abscess secondary to fistula at the angle of His for an average of 19.
