PREOPERATIVE HOSPITALIZATION AS A BRIDGING STRATEGY FOR WEIGHT LOSS IN PATIENTS WITH BODY MASS INDEX = 50 KG/M2 WHO ARE CANDIDATES FOR BARIATRIC SURGERY.

Background: Preoperative hospitalization with the purpose to obtain more effective weight loss provides intensive care for patients who have a higher body mass index (BMI) and associated diseases that involve a greater risk of peri- and postoperative complications. It is a therapeutic strategy that can make it possible to overcome obstacles related to the difficulty of adhering to obesity treatment.

Aims: To analyze the implementation of a preoperative hospitalization strategy for weight loss in patients eligible for bariatric surgery.

SURGICAL SITE INFECTION IN RESECTIONS OF DIGESTIVE SYSTEM TUMOURS.

Postoperative infectious complications are extremely important to surgeons and the entire medical care team. Among these complications, surgical site infection (SSI) appears to be one of the earliest and most prevalent events and is considered an inherent complication of surgical procedures. In oncological patients submitted to resections of digestive system tumors, there is a confluence of several risk factors for SSI, making it necessary to establish measures to maximize the control of this condition to provide a better prognosis for these patients.

GASTRIC TWIST AFTER SLEEVE GASTRECTOMY: A PROPOSAL FOR ENDOSCOPIC CLASSIFICATION.

Objective: The twisting of the gastric tube is one of the main causes of persistent reflux and food intolerance after sleeve gastrectomy (SG). To date, there is no classification for gastric twist after SG. This study aimed to propose an endoscopic classification for this condition and outline the clinical profile of these patients with sleeve gastrectomy.

Data collected included demographic characteristics, length of hospital stay, waiting time for surgery, inflammatory markers, serum levels of micronutrients and dengue virus (DENV) serology.

Is COVID-19 Severity Impacted by Bariatric Surgery in the Early Postoperative Period?

Purpose: The aim of this study was to determine the real influence of bariatric surgery on the clinical evolution of patients infected with SARS-Cov-2 in the postoperative period.

Methods: We conducted a retrospective analysis including two groups of patients: those who presented COVID-19 before bariatric surgery and those who presented it within 3 months of postoperative. Primary outcome was related to the severity of COVID-19, measured by the following variables: presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation.

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.

Purpose: To trace the clinical profile of fistula cases after sleeve gastrectomy (SG) and evaluate the efficacy and safety of endoscopic treatments and the admission costs of these patients.

Methods: This is a retrospective study of patients who developed gastric fistulas after SG. All patients were submitted to surgical and/or endoscopic interventions (self-expandable stent, septotomy, and balloon dilation).

The Impact of the Gastric Twist on Esophagitis Progression After Sleeve Gastrectomy: Mid-Term Endoscopic Findings.

Purpose: To determine the real influence of the gastric twist on the progression of esophagitis after SG, evaluating pre- and late post-operative endoscopic findings.

Material And Methods: We retrospectively included 459 patients submitted to SG between 2009 and 2019. The sample comprised patients who performed esophagogastroduodenoscopy (EGD) at the pre-operative and late post-operative periods.

Nutritional impact of bariatric surgery: a comparative study of Roux-en-Y Gastric Bypass and Sleeve gastrectomy between patients from the public and private health systems.

Purpose: To compare the nutritional status follow up of patients who underwent Roux-en-Y gastric bypass (BGYR) and Sleeve gastrectomy (SG) in hospitals of the private and public health systems, in Pernambuco.

Methods: This study included patients who underwent bariatric surgery in the public and private health systems, in Pernambuco, from 2008 to 2016. Anthropometric and biochemical (hemoglobin, B12, iron and ferritin) data were evaluated in the preoperative period and at 3, 6 and 12 months after the operation.

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.

Predictors of poor follow-up after bariatric surgery.
