Relationship of Food Intolerance 2 Years After Roux-en-Y Gastric Bypass Surgery for Obesity with Masticatory Efficiency and Protein Consumption.

Background: Roux-en-Y gastric bypass (RYGB) is among the most performed bariatric surgery techniques. One known complication of RYGB surgery is food intolerance, which may limit the intake of protein.

Objective: To investigate the relationship of food intolerance after RYGB surgery with masticatory efficiency, chewing time and cycles, and consumption of protein and red meat.

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.

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.

Food Tolerance and Eating Behavior After Roux-en-Y Gastric Bypass Surgery.

Background: Roux-en-Y gastric bypass (RYGB) surgery often leads to food intolerance, especially protein intake.

Aim: This is to investigate the association of food intolerance with protein intake and chewing parameters in patients who underwent RYGB surgery 2 years prior.

Methods: An observational study was carried out in 30 patients aged between 18 and 60 years old with at least a 2-year postoperative period since undergoing RYGB surgery.

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.

A Prospective Single-Arm Trial of Modified Long Biliopancreatic and Short Alimentary Limbs Roux-En-Y Gastric Bypass in Type 2 Diabetes Patients with Mild Obesity.

Background: Type-2 diabetes (T2D) patients with body mass index (BMI) below 35 kg/m carry lower remission rates than severely obese T2D individuals submitted to "standard limb lengths" Roux-en-Y gastric bypass (RYGB). Mild-obese patients appear to have more severe forms of T2D, where the mechanisms of glycemic control after a standard-RYGB may be insufficient. The elongation of the biliopancreatic limb may lead to greater stimulation of the distal intestine, alterations in bile acids and intestinal microbiota, among other mechanisms, leading to better metabolic outcomes.

Sexual dysfunction in obese women is more affected by psychological domains than that of non-obese.

Purpose: To compare differences in the occurrence and changed domains of sexual dysfunction in obese and non-obese Brazilian women.

Methods: Female Sexual Function Index, based on six domains, to investigate 31 sexual dysfunction incidence for obese compared to 32 non-obese women, was used. Statistical analysis using ANOVA and MANOVA were performed to compare total scores of Female Sexual Function Index among groups and to identify the differences among domains, Student t -test was used.

Profile of the obese patients submitted to Roux-en-Y gastric bypass whithout diabetes melittus type 2 remission and/or insufficient weight loss.

Background: The literature reports that gastrojejunal derivation with Roux-en-Y gastric bypass is highly efficient in controlling weight and resolving; but studies have shown worsened glycemic control in a considerable number of patients and associated factors that have not been fully elucidated.

Aim: To analyze the profile of patients submitted to gastric bypass that did not achieve satisfactory weight loss or complete diabetes remission.

Methods: Case-control study of 32 patients submitted to gastric bypass with at least two years postoperative time, unsatisfactory results in terms of weight loss or absence of complete diabetes remission.

Gastric sleeve fixation strategy in laparoscopic vertical sleeve gastrectomy.

Introduction: Initially conceived as the first of two stages in operations such as gastric bypass or duodenal switch in high-risk patients, laparoscopic vertical sleeve gastrectomy has increasingly become the definitive procedure for treating obesity and its comorbidities. Although it is associated with excellent results and postoperative quality of life, a number of complications related to improper position and/or gastric tube deformities, resulting from loss of natural fixation, may be associated to symptoms of persistent food intolerance and/or gastroesophageal reflux.

Aim: To present the gastric fixation strategy in vertical sleeve gastrectomy for the treatment of obesity and related diseases.

[Insufficient loss of weight and/or absence of DM2 remission after Roux-en-Y gastric bypass: factors that may influence the unsatisfactory results].

Background: Roux-en-Y gastric by-pass is considered one of the most effective treatments for maintaining long-term weight loss. However, it is associated to failures manifested by the inability to maintain weight loss, weight gain or poor glycemic control.

Objective: Study the possible factors that influence weight loss failure and/or DM2 remission.

Food tolerance in patients submitted to gastric bypass: the importance of using an integrated and interdisciplinary approach.

Background: Under the restrictive component, patients undergoing gastric bypass may have food intolerance with or without complications.

Methods: This study used quantitative, analytical, observational methodology with patients submitted to Roux-en-Y gastric bypass without the placement of a ring at Hospital Universitário do Rio Grande do Norte in the city of Natal, Brazil between July 2005 and August 2010. Out of 176 patients monitored after surgery by the interdisciplinary team, 47 took part in the study.
