Background: The role of preoperative upper-gastrointestinal endoscopy for bariatric surgery is still understood only with controversy. The aim of this study was to evaluate the prevalence of endoscopic findings and its impact on perioperative management. Methods: Patients who underwent bariatric surgery at our center between 2010 and 2013 were systematically analyzed from a prospective database. Results: Two hundred and twelve patients with a median body mass index of 50 kg/m2 (range 29-87) underwent 216 bariatric procedures at our center between 2010 and 2013. All patients received preoperative upper endoscopy. In 159 cases (75%), the endoscopy was performed at our center. These cases were included in this study. In 37 cases (23%), no abnormal findings were detected. In 122 cases (76%), upper endoscopy revealed pathologies. No further treatment was necessary in 24 cases (15%). Medical treatment was changed in 81 cases (51%). The operation was delayed due to medical treatment and re-endoscopy in 13 cases (8%). The surgical approach was changed in 4 cases (3%). Conclusion: Routinely performed preoperative endoscopy before bariatric surgery revealed a high prevalence of gastrointestinal diseases with a significant impact on perioperative management in two thirds of the cases. Therefore, we recommend routine gastroscopy about 2-4 weeks prior to surgery.

Obesity is the 21st century pandemic. By 2025 6 % of men and 9 % of women will suffer from morbid obesity. For morbid obesity bariatric surgery is the main treatment option. The presence of pathology of the upper gastrointestinal tract (GERD) determines the choice of surgical intervention. The study involved 68 patients 47.1 ± 10.2 years with morbid obesity. Patients had the following gastroenterological pathologies: erosive esophagitis – 6 (8.8 %), hiatal hernia – 9 (13 %), erosive and ulcerative lesions of the stomach and duodenum – 13 (19 %). Heartburn disturbed 38 (55 %), regurgitation – 17 (25 %), severity and feeling of fullness in the epigastrium – 29 (42 %), pain or burning in the epigastrium – 8 (11 %) patients. Fifty (73.5 %) patients underwent laparoscopic sleeve gastrectomy, 18 (26.5 %) patients – laparoscopic Roux-en-Y gastric bypass. Comprehensive preoperative examination (x-ray of the upper gastrointestinal tract with barium, daily pH impedance measurement, esophageal manometry) and phenotyping of GERD lead to reduction of GERD symptoms in patients with morbid obesity after sleeve gastrectomy.

Before And After

Background: Healthcare use and costs are about 81% higher for morbidly obese individuals compared to non-obese persons, and 47% higher compared to the non-morbidly obese population. The benefits of bariatric surgery for health are well established, but its mid-term impact on healthcare use and costs remains controversial.Methods: This study examines the trends in healthcare use and costs in a Brazilian cohort during a 4-year period before and after surgery. Healthcare use and direct costs related to inpatients and outpatients were retrieved from a healthcare insurance company database from which all cohort members were selected.Results: Between 2004 and 2010, 4,006 individuals underwent bariatric surgery. Most patients were female (80%) with a mean age of 36.2 years and a mean body mass index of 42.8 kg/m2. Elevated blood pressure was present in 38% of cases and diabetes was found in 12.5% of subjects. Hospital admissions increased consistently after surgery, even after excluding hospitalizations for esthetic surgery and pregnancy-related care. The most prevalent conditions in this group were gastrointestinal diseases. Emergency department visits increased after bariatric procedures, in particular for genitourinary and hematologic problems. Adjusted costs were higher after surgery as assessed during a 4-year follow-up period.Conclusion: Results indicate that costs and hospital admissions after bariatric surgery increase following this procedure, even when elective interventions are excluded. Healthcare providers and policy makers need to be aware that a decrease in obesity-related diseases following bariatric surgery does not reduce healthcare use and costs.

Background and aims: Overweight and obese patients who undergo bariatric surgery require a rigorous clinical and paraclinical assessment both before and after the surgery at 3, 6, and 12 months.The present study aims the assessment of serum leptin levels and insulin resistance status in compliant bariatric patients to scheduled medical laboratory assessment at 6 months after surgery. Material and Method: The study included 109 eligible patients selected for bariatric surgery, 48 of whom attended the scheduled visit at 6 months after the surgery. Laboratory assessing regarded the insulin resistance by determining before meal the serum levels of leptin, glucose and insulin, as well as HOMA 1 and HOMA 2 indexes. Results: Patients who underwent bariatric treatment experienced a significant decrease in insulin resistance status. A higher percentage in the preoperative group was recorded in women, feature which was also recorded in the postoperative group that attended the scheduled visit at 6 months after surgery. Age is also an important factor that significantly influences the behavioral adherence to postoperative visits. Conclusions: Insulin resistance status improved significantly in 6 months after bariatric surgery among the fully compliant patients. The percentage of attendance at scheduled visits is higher among women, and decreases with age. Keywords: obesity surgery, leptin resistance, insulin resistance, HOMA index, compliance

The Impact

The aim of this study was to explore the impact of bariatric surgery on fat and sweet taste perceptions and to determine the possible correlations with gut appetite-regulating peptides and subjective food sensations. Women suffering from severe obesity (BMI > 35 kg/m2) were studied 2 weeks before and 6 months after a vertical sleeve gastrectomy (VSG, n = 32) or a Roux-en-Y gastric bypass (RYGB, n = 12). Linoleic acid (LA) and sucrose perception thresholds were determined using the three-alternative forced-choice procedure, gut hormones were assayed before and after a test meal and subjective changes in oral food sensations were self-reported using a standardized questionnaire. Despite a global positive effect of both surgeries on the reported gustatory sensations, a change in the taste sensitivity was only found after RYGB for LA. However, the fat and sweet taste perceptions were not homogenous between patients who underwent the same surgery procedure, suggesting the existence of two subgroups: patients with and without taste improvement. These gustatory changes were not correlated to the surgery-mediated modifications of the main gut appetite-regulating hormones. Collectively these data highlight the complexity of relationships between bariatric surgery and taste sensitivity and suggest that VSG and RYGB might impact the fatty taste perception differently.

<b><i>Introduction:</i></b> Bariatric surgery results in both intentional and unintentional metabolic changes. In a high-volume bariatric center, extensive laboratory panels are used to monitor these changes pre- and postoperatively. Consecutive measurements of relevant biochemical markers allow exploration of the health state of bariatric patients and comparison of different patient groups. <b><i>Objective:</i></b> The objective of this study is to compare biomarker distributions over time between 2 common bariatric procedures, i.e., sleeve gastrectomy (SG) and gastric bypass (RYGB), using visual analytics. <b><i>Methods:</i></b> Both pre- and postsurgical (6, 12, and 24 months) data of all patients who underwent primary bariatric surgery were collected retrospectively. The distribution and evolution of different biochemical markers were compared before and after surgery using asymmetric beanplots in order to evaluate the effect of primary SG and RYGB. A beanplot is an alternative to the boxplot that allows an easy and thorough visual comparison of univariate data. <b><i>Results:</i></b> In total, 1,237 patients (659 SG and 578 RYGB) were included. The sleeve and bypass groups were comparable in terms of age and the prevalence of comorbidities. The mean presurgical BMI and the percentage of males were higher in the sleeve group. The effect of surgery on lowering of glycated hemoglobin was similar for both surgery types. After RYGB surgery, the decrease in the cholesterol concentration was larger than after SG. The enzymatic activity of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphate in sleeve patients was higher presurgically but lower postsurgically compared to bypass values. <b><i>Conclusions:</i></b> Beanplots allow intuitive visualization of population distributions. Analysis of this large population-based data set using beanplots suggests comparable efficacies of both types of surgery in reducing diabetes. RYGB surgery reduced dyslipidemia more effectively than SG. The trend toward a larger decrease in liver enzyme activities following SG is a subject for further investigation.
