The association of gastric plication with fundoplication is a reliable option for the treatment of individuals with obesity associated with gastroesophageal reflux disease.
To describe weight loss, endoscopic, and gastroesophageal reflux disease-related outcomes of gastric plication with fundoplication in individuals with mild obesity.
A retrospective cohort study was carried out, enrolling individuals who underwent gastric plication with fundoplication at a tertiary private hospital from 2015–2019. Data regarding perioperative and weight loss outcomes, endoscopic and 24-hour pH monitoring findings, and gastroesophageal reflux disease-related symptoms were analyzed.
Of 98 individuals, 90.2% were female. The median age was 40.4 years (IQR 32.1–47.8). The median body mass index decreased from 32 kg/m2 (IQR 30,5–34) to 29.5 kg/m2 (IQR 26.7–33.9) at 1–2 years (p<0.05); and to 27.4 kg/m2 (IQR 24.1–30.6) at 2–4 years (p=0.059). The median percentage of total weight loss at 1–2 years was 7.8% (IQR −4.1–14.7) and at 2–4 years, it was 16.4% (IQR 4.3–24.1). Both esophageal and extra-esophageal symptoms showed a significant reduction (p<0.05). A significant decrease in the occurrence of esophagitis was observed (p<0.01). The median DeMeester score decreased from 30 (IQR 15.1–48.4) to 1.9 (IQR 0.93–5.4) (p<0.0001).
The gastric plication with fundoplication proved to be an effective and safe technique, leading to a significant and sustained weight loss in addition to endoscopic and clinical improvement of gastroesophageal reflux disease.
Despite its increasing popularity, laparoscopy is not the option for bariatric surgeries performed in the Brazilian public health system.
To compare laparotomy and laparoscopic access in bariatric surgery, considering aspects such as morbidity, mortality, costs, and length of stay.
The study included 80 patients who were randomly assigned to perform a Roux-en-Y gastric bypass. They were equally divided in two groups, laparoscopic and laparotomy. The results obtained in the postoperative period were evaluated and compared according to the Ministry of Health protocol, and later, in their outpatient returns.
The surgical time was similar in both groups (p=0.240). The costs of laparoscopic surgery proved to be higher, mainly due to staplers and staples. The patients included in the laparotomy group presented higher rates of severe complications, such as incisional hernia (p<0.001). Costs related to social security and management of postoperative complications were higher in the open surgery group (R$ 1,876.00 vs R$ 34,268.91).
The costs related to social security and treatment of complications were substantially lower in laparoscopic access when compared to laparotomy. However, considering the operative procedure itself, the laparotomy remained cheaper. Finally, the length of stay, the rate of complications, and return to labor had more favorable results in the laparoscopic route.
Fat, muscle, and bone are endocrine organs capable of affecting the metabolic profile and cardiovascular risk. Relating these components is important to the establishment of early intervention strategies for overweight patients.
This study aimed to evaluate the influence of body mass components on the metabolic profile and cardiovascular risk in the preoperative period of bariatric surgery.
A cross-sectional study was conducted with patients admitted for bariatric surgery at a university hospital in the city of Recife, Brazil, between 2018 and 2019. Body composition was determined using dual-energy x-ray absorptiometry. Cardiovascular risk was assessed using the Framingham risk score. Data were collected on anthropometric, clinical, and lifestyle characteristics. The lipid profile (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides), blood glucose, and vitamin D were determined using the standard methods of the hospital laboratory.
A total of 60 patients were analyzed, 86.7% of whom had comorbidities, 33.3% had moderate/high cardiovascular risk, and 71.4% had vitamin D insufficiency/deficiency. Lower lean body mass (adjusted PR 3.24; 95%CI 1.19–5.77) was independently associated with the severity of obesity. The body mass index and waist circumference were negatively correlated with lean body mass (r=-0.52; p<0.01)/r=-0.36; p<0.01). Lean body mass was negatively correlated with fat mass (r=-0.26; p<0.05), trunk fat (r=-0.29; p<0.05), fasting glucose (r=-0.26; p<0.05), and bone mineral density (r=-0.26; p<0.05). A total of 84.2% of individuals with less trunk fat tended to have low cardiovascular risk (p=0.05). However, physical inactivity (adjusted PR 2.14; 95%CI 1.19–5.54) and the risk of alcohol dependence (adjusted PR 2.41; 95%CI 1.76–4.15) were the only variables independently associated with cardiovascular risk.
Obese patients in the preoperative period of bariatric surgery with less trunk fat tended to have low cardiovascular risk. However, the other components of body mass were also not associated with cardiovascular risk.
Obesity is associated with different medical conditions, such as cardiologic, respiratory, gastrointestinal, and genitourinary, and constitutes a severe health problem.
This study aimed to evaluate the use of intragastric fluid-filled balloon in the reduction of weight and other measurements related to body composition.
This is a retrospective, monocentric study involving all patients who opted for the intragastric balloon Spatz® placement from January 2018 to July 2019, with fulfillment of inclusion and exclusion criteria. The patients were analyzed after 6 and 12 months after the intragastric fluid-filled balloon placed.
A total of 121 subjects were included in this study, with 83 (68.6%) females and 38 (31.4%) males. The mean age was 36 years and height was 1.64±0.09. Weight mean and standard deviation was 89.85±14.65 kg, and body mass index was 33.05±4.03; body mass index decreased to 29.4 kg/m2 with a mean weight of 79.83 kg, after 12 months of follow-up. There were statistical differences between body mass index and the 12 months in fat percentage, fat-free mass (kg), visceral fat area, and basal metabolic rate. There was a significant variation according to gender, with males having highest reduction. The percentage of excess weight loss was 46.19, and the total weight loss was 9.24 at the end of the study.
The study demonstrated a benefit of intragastric fluid-filled balloon on weight loss after 12 months. At the end of treatment, body mass index and the measurements of body composition were significantly lower. Men benefited more than women from the treatment.
Although bariatric surgery is highly effective for the treatment of obesity and its comorbidities, preoperative weight loss has an impact on its results.
Although bariatric surgery is highly effective for the treatment of obesity and its comorbidities, preoperative weight loss has an impact on its results.
The aim of this study was to correlate preoperative weight loss with the outcome of bariatric surgery using the Bariatric Analysis and Reporting Outcome System scores.
This is a cross-sectional, observational study with 43 patients undergoing bariatric surgery that compared a group of 25 patients with a percentage of preoperative excess weight loss ³8% with a group of 18 patients with a percentage of preoperative excess weight loss <8% or with weight gain. The research took place at the bariatric surgery outpatient clinic of the Oswaldo Cruz University Hospital with patients 1 year after the surgery.
Patients had a mean age of 40.8 years (42.7 percentage of preoperative excess weight loss ≥8% vs. 38.2 percentage of preoperative excess weight loss <8%, p=0.095). No significant difference was found between the two groups regarding preoperative comorbidities and body mass index at entry into the program. Higher preoperative body mass index (48.69 vs. 44.0; p=0.029) was observed in the group with percentage of preoperative excess weight loss <8%. No significant difference was found regarding the percentage of excess weight loss (71.4±15.4%; percentage of preoperative excess weight loss ≥8% vs. 69.47%±14.5 percentage of preoperative excess weight loss <8%; p=0.671), the result of the surgery according to the Bariatric Analysis and Reporting Outcome System scores protocol, the resolution of comorbidities, the quality of life, and the surgical complications between the two groups.
Based on the available data, it is reasonable that bariatric surgery should not be denied to people who have not achieved pre-established weight loss before surgery.
: Obese people have abnormal deposition of fat in the vocal tract that can interfere with the acoustic voice.
: To relate the fundamental frequency, the maximum phonation time and voice complaints from a group of morbidly obese women.
: Observational, cross-sectional and descriptive study that included 44 morbidly obese women, mean age of 42.45 (±10.31) years old, observational group and 30 women without obesity, control group, with 33.79 (±4.51)years old. The voice recording was done in a quiet environment, on a laptop using the program ANAGRAF acoustic analysis of speech sounds. To extract the values of fundamental frequency the subjects were asked to produce vowel [a] at usual intensity for a period in average of three seconds. After the voice recording, participants were prompted to produce sustained vowel [ a] , [ i] and [ u] at usual intensity and height, using a stopwatch to measure the time that each participant could hold each vowel.
: The majority, 31(70.5%), had vocal complaints, with a higher percentage for complaints of vocal fatigue 20(64.51%) and voice failures 19(61.29%) followed by dryness of the throat in 15 (48.38%) and effort to speak 13(41.93%). There was no statistically significant difference regarding the mean fundamental frequency of the voice in both groups, but there was significance between the two groups regarding maximum phonation.
: Increased adipose tissue in the vocal tract interfered in the vocal parameters.
Obesity is associated to several comorbidities, including nonalcoholic fatty liver disease, which implicates in isolated steatosis to steatohepatitis. The latter may progress to severe manifestations such as liver fibrosis, cirrhosis and hepatocellular carcinoma.
To compare the presence of advanced liver fibrosis before and after bariatric surgery in patients of private and public health system.
Patients from public and privative networks were studied before and after bariatric surgery. The presence or absence of advanced hepatic fibrosis was evaluated by NAFLD Fibrosis Score, a non-invasive method that uses age, BMI, AST/ALT ratio, albumin, platelet count and the presence or absence of hyperglycemia or diabetes. The characteristics of the two groups were compared. The established statistical significance criterion was p<0.05.
Were analyzed 40 patients with a mean age of 34.6±9.5 years for private network and 40.6± 10.2 years for public. The study sample, 35% were treated at private health system and 65% in the public ones, 38% male and 62% female. Preoperatively in the private network one (7.1%) patient had advanced liver fibrosis and developed to the absence of liver fibrosis after surgery. In the public eight (30.8%) patients had advanced liver fibrosis preoperatively, and at one year after the proportion fell to six (23%).
The non-alcoholic fatty liver disease in its advanced form is more prevalent in obese patients treated in the public network than in the treated at the private network and bariatric surgery may be important therapeutic option in both populations.
Nowadays obesity is a chronic disease considered one of the greatest problems in public healthy. Showing to be effective in a short and long term, the bariatric surgery has emerged as an optional treatment for morbid obesity.
Identify the profile of patients seeking bariatric surgery.
Were interviewed 100 patients in preoperative nutritional monitoring of bariatric surgery. The study was conducted by applying a questionnaire prepared according to the research objectives.
From the individuals that were seeking bariatric surgery, 78% were female, 62% were married and 69% reported physical activity. The average age of those surveyed was 37±10.83 years and mean body mass index (BMI) was 43.51± 6.25 kg/m². The comorbidity more prevalent in this group was high blood pressure (51%). In previous treatments for weight reduction, 92% have already done hypocaloric diet followed by anorectic drug (83%). The success of these treatments was reported by 92% of patients; however, the weight lost was recovered in less than one year of 75%. Patients with diabetes mellitus and dyslipidemia had higher BMI values. The patients with comorbidities showed lower levels of BMI.
The profile of patients who sought surgical treatment for their obesity were predominantly women with a family background of obesity and obesity-related comorbidities, especially hypertension and diabetes mellitus.
It is recommended that bariatric surgery candidates undergo psychological assessment. However, no specific instrument exists to assess the psychological well-being of bariatric patients, before and after surgery, and for which all constructs are valid for both genders.
This study aimed to develop and validate a new psychometric instrument to be used before and after bariatric surgery in order to assess psychological outcomes of patients.
This is a cross-sectional study that composed of 660 individuals from the community and bariatric patients. BariTest was developed on a Likert scale consisting of 59 items, distributed in 6 constructs, which assess the psychological well-being that influences bariatric surgery: emotional state, eating behavior, quality of life, relationship with body weight, alcohol consumption, and social support. Validation of BariTest was developed by the confirmatory factor analysis to check the content, criteria, and construct. The R statistical software version 3.5.0 was used in all analyses, and a significance level of 5% was used.
Adjusted indices of the confirmatory factor analysis model indicate adequate adjustment. Cronbach’s alpha of BariTest was 0.93, which indicates good internal consistency. The scores of the emotional state, eating behavior, and quality of life constructs were similar between the results obtained in the community and in the postoperative group, being higher than in the preoperative group. Alcohol consumption was similar in the preoperative and postoperative groups and was lower than the community group.
BariTest is a reliable scale measuring the psychological well-being of patients either before or after bariatric surgery.
The influence of body mass index on perioperative complications of hiatal hernia surgery is controversial in the surgical literature.
The aim of this study was to evaluate the influence of body mass index on perioperative complications and associated risk factors for its occurrence.
Two groups were compared on the basis of body mass index: group A with body mass index <32 kg/m2 and group B with body mass index ³32 kg/m2. A multivariate analysis was carried out to identify independent predictors for complications. Complications were classified based on the Clavien-Dindo score.
A total of 49 patients were included in this study, with 30 in group A and 19 in group B. The groups were compared based on factors, such as age, Charlson Comorbidity Index, surgical techniques used, type and location of hiatal hernia, and length of stay. Findings showed that 70% of patients had complex hiatal hernia. In addition, 14 complications also occurred: 7 pleuropulmonary and 7 requiring reoperation. From the seven reoperated, there were three recurrences, two gastrointestinal fistulas, one diaphragmatic hernia, and one incisional hernia. Complications were similar in both the groups, with type IV hiatal hernia being the only independent predictor.
Body mass index does not affect perioperative complications in anti-reflux surgery and type IV hiatal hernia is an independent predictor of its occurrence.
