Brazilian national bariatric registry - pilot study.

Introduction: Brazil is a world leader in bariatric surgery. However, the actual number of surgeries performed in the country is still unknown. It is necessary to implement an instrument to monitor the quality of care provided.

ARE THERE BENEFITS IN PERFORMING GASTRO-OMENTOPEXY IN LAPAROSCOPIC VERTICAL GASTRECTOMY?

Background: Gastro-omentopexy promotes the reconnection of the stomach to the gastroesplenic and gastrocolic ligaments and constitutes an alternative for the prevention of complications in laparoscopic vertical gastrectomy.

Aim: To demonstrate the benefits of the gastro-omentopexy technique in patients undergoing sleeve gastrectomy, with possible reduction in postoperative complications.

Methods: Prospective, non-randomized, case series type study, consisting of a clinical population of 179 patients who underwent the technique in 2018, with follow-up between 6-12 months in the postoperative period.

IFSO Endoscopy Committee Position Statement on the Practice of Bariatric Endoscopy During the COVID-19 Pandemic.

COVID-19 (Coronavirus disease 2019) caused by SARS-CoV-2 has become a global pandemic. Obesity is a risk factor for severe disease, and the practice of endoscopy poses special challenges and risks of SARS-CoV-2 transmission to patients and providers given the evolving role of the gastrointestinal tract in viral transmission and aerosol generation during endoscopic procedures. It is therefore necessary to distinguish between urgent interventions that cannot be postponed despite the risks during the pandemic and, in contrast, purely elective interventions that could be deferred in order to minimize transmission risks during a time of infection surge and limited access.

Does weight gain, throughout 15 years follow-up after Nissen laparoscopic fundoplication, compromise reflux symptoms control?

Background: Gastroesophageal reflux disease is defined by the abnormal presence of gastric content in the esophagus, with 10% incidence in the Western population, being fundoplication one treatment option.

Aim: To evaluate the early (six months) and late (15 years) effectiveness of laparoscopic fundoplication, the long term postoperative weight changes, as well as the impact of weight gain in symptoms control.

Methods: Prospective study of 40 subjects who underwent laparoscopic Nissen's fundoplication.

Isolated intestinal transit bipartition: a new strategy for staged surgery in superobesity.

Objective: biliopancreatic diversion with duodenal switch is a complex, malabsorptive procedure, associated with improved weight loss and metabolic control. Staged surgery with sleeve gastrectomy as the first stage is an option for reducing complications in superobese patients. However, some problems persist: large livers can hamper the surgical approach and complications such as leaks can be severe.

International multicenter expert survey on endoscopic treatment of upper gastrointestinal anastomotic leaks.

 A variety of endoscopic techniques are currently available for treatment of upper gastrointestinal (UGI) anastomotic leaks; however, no definite consensus exists on the most appropriate therapeutic approach. Our aim was to explore current management of UGI anastomotic leaks.  A survey questionnaire was distributed among international expert therapeutic endoscopists regarding management of UGI anastomotic leaks.

INTERNAL HERNIA FOLLOWING LAPAROSCOPIC ROUX-EN-Y GASTRIC BY-PASS: INDICATIVE FACTORS FOR EARLY REPAIR.

Background: Internal hernia (IH) following laparoscopic Roux-en-Y gastric bypass (LRYGB) is a major complication that challenges the surgeon due to its non-specific presentation and necessity of early repair. Delayed diagnosis and surgical intervention of IH might lead to increased morbidity of patients and impairments in their quality of life.

Objective: To evaluate the predictive factors for early diagnosis and surgical repair of IH after LRYGB.

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).

Roux-en-Y gastric bypass for nonobese patients with uncontrolled type 2 diabetes: a long-term evaluation.

Background: There is growing evidence that the impact of Roux-en-Y gastric bypass (RYGB) on type 2 diabetes (T2D) occurs regardless of the amount of weight loss. Taking this background into consideration, it is plausible to study this procedure in individuals with lower body mass index (BMI) under clinical treatment failure for uncontrolled T2D.

Objectives: To elucidate the long-term impact of RYGB on T2D regression in a non-obese population.

Micronutrient deficiencies following bariatric surgery: a comparative analysis between sleeve gastrectomy and Roux-en-Y gastric bypass.

Objective: to compare the prevalence of micronutrient deficiencies in patients submitted to sleeve gastrectomy (SG) and Roux- en-Y gastric bypass (RYGB).

Methods: this is a comparative study of 576 patients submitted to bariatric surgery, 338 to SG and 238 to RYGB, and evaluated for hemoglobin, iron, ferritin, zinc and vitamin B12 serum levels. We performed these dosages in the preoperative period and at three, six, 12 and 24 months after surgery, for analysis and comparison of micronutrient deficiencies among the techniques.

Omentopexy in Sleeve Gastrectomy Reduces Early Gastroesophageal Reflux Symptoms.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is one of the surgical procedures indicated in the treatment of obesity. The occurrence of gastroesophageal reflux (GER) in the postoperative period of this surgery is related to a reduction in the lower esophageal sphincter (LES) tone and the presence of gastric residual fundus (RF) associated with increased gastric intraluminal pressure. Fixation of the remaining gastric reservoir to the gastrosplenic and gastrocolic ligaments (omentopexy) has emerged as a technical option to avoid or decrease GER in the postoperative period of LSG.

Evaluation of factors that may influence in the insufficient weight loss in patients after two years of Roux-en-Y gastric bypass.

Introduction: bariatric surgery is a favorable option for the treatment of obesity, resulting in long-term weight loss.

Objectives: to analyze whether feeding behavior, evaluated by caloric intake, dietary preferences and tolerance, can be considered as a determinant factor for weight loss in obese patients submitted to Roux-en-Y gastric bypass (RYGB).

Methods: cross-sectional study of 105 patients with at least two years post-RYGB surgery with a preoperative body mass index (BMI) of ≥ 35 kg/m².

Intragastric Balloon Hyperinsufflation as a Cause of Acute Obstructive Abdomen.

Recently, the Food and Drug Administration approved the use of the Orbera balloon for obesity treatment. However, the Food and Drug Administration later issued a warning about the possibility of 2 complications not previously reported: acute pancreatitis and balloon hyperinsufflation. This case report is intended to alert all clinicians that, although rare, cases of hyperinsufflation should be considered in patients with an intragastric balloon (IGB) and acute abdomen.

Long-term repercussions of Roux-en-Y gastric bypass in a low-income population: assessment ten years after surgery.

Objective: to evaluate the weight, nutritional and quality of life of low-income patients after ten years of Roux-en-Y gastric bypass (RYGB).

Methods: we conducted a longitudinal, retrospective and descriptive study evaluating the excess weight loss, weight regain, arterial hypertension, type 2 diabetes mellitus, anemia and hypoalbuminemia in 42 patients of social classes D and E submitted to RYGB. We assessed quality of life through the Bariatric Analysis and Reporting Outcome System (BAROS).

Management of Bariatric Complications Using Endoscopic Stents: a Multi-Center Study.

Background: Complications after bariatric procedures including leaks and strictures can be difficult to treat. Endoscopic treatment may be preferable due to its less invasiveness. The aim of this study is to describe usage of stents in treating complications after bariatric procedures, along with its indications, methods, and outcome.

The Impact of Bariatric Surgery on Cardiopulmonary Function: Analyzing VO Recovery Kinetics.

Purpose: To assess cardiopulmonary capacity, autonomic heart function, and oxygen recovery kinetics during exercise testing before and after bariatric surgery.

Methods: This is a prospective cohort study. Symptom-limited cardiopulmonary exercise testing was performed with 24 patients, 1 week before and 4 months after bariatric surgery.

Robotic-assisted bariatric surgery: case series analysis and comparison with the laparoscopic approach.

Objective: to report a series of cases of robotic bariatric surgery in the treatment of obesity in Brazil.

Methods: we evaluated patients undergoing robotic bariatric surgery at the Garrido Institute and compared them with a group submitted to conventional laparoscopic surgery.

Results: we analyzed 45 patients, with a mean age of 39.

PHYSICAL ACTIVITY, QUALITY OF LIFE AND BODY IMAGE OF CANDIDATES TO BARIATRIC SURGERY.

Background: Physical activity enhances quality of life and body image in obese. Behavioural changes are useful tools to increase life conditions of this population.

Aim: To evaluate the physical activity level of candidates to bariatric surgery and its relation with quality of life and body image, when patients are encouraged weekly by personal trainers.

Perception of body image by patients undergoing bariatric surgery.

Objective: to investigate changes in body image perception in patients undergoing bariatric surgery, evaluating the accuracy/inaccuracy in body size estimation and satisfaction/dissatisfaction with own body after surgery.

Methods: we performed a survey at the General Surgery outpatient clinic of the Clinics Hospital of the Federal University of Pernambuco. Thirty-six patients aged 18 years and older undergoing bariatric surgery participated.

Efficacy and Safety of Stents in the Treatment of Fistula After Bariatric Surgery: a Systematic Review and Meta-analysis.

Fistula development is a serious complication after bariatric surgery. We performed a systematic review and meta-analysis to assess the efficacy of fistula closure and complications associated with endoscopic stent treatment of fistulas, developed after bariatric surgeries, particularly Roux-en-Y gastric bypass (RYGB) and gastric sleeve (GS). Studies involving patients with fistula after RYGB or GS and those who received stent treatment only were selected.

DIABETES REMISSION RATE IN DIFFERENT BMI GRADES FOLLOWING ROUX-EN-Y GASTRIC BYPASS.

Background: Type 2 diabetes mellitus has a high long-term remission rate after laparoscopic Roux-en-Y gastric bypass (LRYGB), but few studies have analyzed patients with BMI<35 kg/m2.

Aim: To compare glycemic control after LRYGB between BMI 30-35 kg/m2 (intervention group or IG) and >35 kg/m2 patients (control group or CG) and to evaluate weight loss, comorbidities and surgical morbidity.

Methods: Sixty-six diabetic patients (30 in IG group and 36 in CG group) were submitted to LRYGB.

FUNDOPLICATION CONVERSION IN ROUX-EN-Y GASTRIC BYPASS FOR CONTROL OF OBESITY AND GASTROESOPHAGEAL REFLUX: SYSTEMATIC REVIEW.

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.
