Introduction: Despite Sleeve Gastrectomy (SG) being the most commonly performed bariatric surgery today, studies with over 5 years of follow-up show that patients undergoing SG have inferior weight loss compared to those undergoing Roux-en-Y gastric bypass (RYGB). The aim of this study was to examine differences in weight loss and the prevalence of weight regain between SG and RYGB up to 8 years after surgery.
Methods: Retrospective study including adult patients undergoing SG or RYGB between 2015 and 2018 at a tertiary center in Brazil.
Background: : The II Brazilian Consensus on Gastric Cancer of the Brazilian Gastric Cancer Association BGCA (Part 1) was recently published. On this occasion, countless specialists working in the treatment of this disease expressed their opinion in the face of the statements presented.
Aim: : To present the BGCA Guidelines (Part 2) regarding indications for surgical treatment, operative techniques, extension of resection and multimodal treatment.

Background: The II Brazilian Consensus on Gastric Cancer by the Brazilian Gastric Cancer Association (ABCG) was recently published. On this occasion, several experts in gastric cancer expressed their opinion before the statements presented.
Aim: To present the ABCG Guidelines (part 1) regarding the diagnosis, staging, endoscopic treatment and follow-up of gastric cancer patients.
Background: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated.
Aim: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition.
Methods: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers "fully agree" and "partially agree" was reached.
Background: Malnutrition is very prevalent in patients with gastric cancer and increases the risk of morbidity and mortality. Adductor pollicis muscle thickness (APMT) appears as an important objective, quick, inexpensive and noninvasive measure to assess the muscle compartment.
Aim: To compare APMT and other nutritional assessment methods and to correlate these methods with postoperative mortality.
Objectives: to determine the nutritional evaluation method that best predicts mortality in 90 days of patients submitted to gastrectomy for gastric cancer.
Methods: we conducted a prospective study with 44 patients with gastric cancer, stages II to IIIa, of whom nine were submitted to partial gastrectomy, 34 to total gastrectomy, and one to esophago-gastrectomy. All patients were nutritionally evaluated through the same protocol, up to 72h after hospital admission.
Background: Morbid obesity is a state of insulin resistance combined with excess of visceral fat, which contributes to the development of metabolic syndrome (MetS). Nonsurgical treatment of obesity usually improves MetS, but there is no ultimate resolution and weight regain is common. Surgical options like Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) result in a significant and sustained weight loss accompanied by improvement of MetS.

Methods: two hundred and fifty eight Ob2,3 patients were selected in a retrospective analysis and included in a case control study. MetS was defined as described by the International Diabetes Federation.
Context: Nonalcoholic fatty liver disease encompasses a spectrum of histopathological changes that range from simple steatosis to nonalcoholic steatohepatitis. Works suggest that iron (Fe) deposits in the liver are involved in the physiopathology of nonalcoholic steatohepatitis.
Objective: The aim of this study was to determine the prevalence of simple steatosis and nonalcoholic steatohepatitis in patients with morbid obesity, subjected to bariatric surgery and to establish a correlation of the anatomopathological findings with the presence of liver fibrosis.
Background: In Brazil, gastric cancer is the fourth most common malignancy among men and sixth among women. The cause is multivariate and the risks are well known. It has prognosis and treatment defined by the location and staging of the tumor and number of lymph nodes resected and involved.

The aim of this study was to determine which nutritional assessment method better predicts outcome. Seventy-four patients, 45 men and 29 women; mean (SD) age of 63 (102) yr (range = 34 to 83), undergoing surgical resections for esophageal (n = 19) gastric (n = 43) and pancreatic (n = 12) tumors were preoperatively assessed by Patient Generated Subjective Global Assessment, anthropometry, and by laboratory sampling.
