The prevalence of overweight and obesity is steadily increasing in Austria as well as internationally. Obesity in particular is associated with multiple health risks, comorbidities, functional disability, and social stigma. Obesity is an independent, complex, chronic disease and should be treated as such by a multidisciplinary team of appropriately qualified personnel. In addition to recent international guidelines, this consensus paper outlines the overall principles of the management of overweight and obesity and provides guidance for the diagnosis and conservative treatment, focusing on lifestyle modifications and pharmacotherapy. Using the "5A" framework of behavioral health intervention, guidelines for a structured, pragmatic, and patient-centered medical care of adults with overweight or obesity are presented.

BACKGROUND: The increase in obesity has become a major public health concern. Morbid obesity is associated with co-morbidities, reduced quality-of-life, and death. Metabolic surgery (MS) is the most effective treatment for obesity. OBJECTIVES: The aim of this study was to evaluate the costs and outcomes of MS compared with no surgery in patients with a body mass index ≥30 kg/m2. SETTING: Health care system, Austria METHODS: A total of 177 patients who underwent MS were documented retrospectively, based on the hospital records of 2 specialized centers in Austria, over a 1-year period. At baseline 26.0% of patients exhibited type 2 diabetes (T2D), 52.5% cardiovascular disease (CVD), 23.2% hyperlipidemia, and 23.7% depression. Following the observation period, a Markov chain simulation model was developed to analyze the long-term consequences of T2D, including diabetic complications, CVD, hyperlipidemia, depression, non-alcoholic steatohepatitis (NASH), myocardial infarction, and stroke, over a total of 20 years. Direct medical costs were expressed in 2017 euros from the payer's perspective. Quality-adjusted life years (QALYs), life years (LYs), and costs were discounted. RESULTS: MS led to costs of 40,427 and 9.58 QALYs (15.58 LYs) per patient over 20 years. No MS was associated with 64,819 and 6.33 QALYs (13.92 LYs). Total cost-savings amounted to 24,392, which offset the cost of the procedure including re-operations. Over 20 years MS saved -6.7 patient-years per patient with T2D, -5.8 patient-years with CVD, -1.5 patient-years with hyperlipidemia, -1.8 patient-years with depression, and -3.8 patient-years with NASH. CONCLUSION: MS is associated with substantial savings in long-term costs, expected health benefits, and reduced onset of complications. MS significantly increases quality of life.

INTRODUCTION: Sleeve gastrectomy (SG) is the most common bariatric operation with over 340,000 procedures per year. There are only few studies presenting follow-up results >10 years in the literature today. The aim of this study was the objective evaluation of long-term outcomes of at least 15 years after SG in non-converted patients. METHODS: This study (multicenter cross-sectional; university-hospital based) includes all non-converted patients with primary SG before December 2005 at participating bariatric centers. The following methods were used: gastroscopy, esophageal manometry, 24-h pH-metry, and Gastrointestinal Quality of Life Index (GIQLI). RESULTS: After removing converted patients, patients with bariatric procedures before SG, and deceased patients from the cohort, 20 of 53 participants have met the inclusion criteria. Of this group, 55% are suffering from symptomatic gastroesophageal reflux disease (GERD); 45% are without GERD. Esophagitis, hiatal hernias, Barrett's esophagus, and enlarged sleeves were found in 44%, 50%, 13%, and 69% of patients during gastroscopy. Mean lower esophageal sphincter pressure was normal at 20.2 ± 14.1 mm Hg during manometry. Reflux activity in 24 h, number of refluxes, and DeMeester score were increased at 12.9 ± 9.7%, 98.0 ± 80.8, and 55.3 ± 36.3 during 24-h pH-metry. Patients with GERD scored significantly lower in the GIQLI than patients without GERD: 107.6 ± 18.4 versus 127.6 ± 14.4 (p = 0.04). DISCUSSION/CONCLUSION: Fifteen years after primary SG, objective testing has shown that GERD, esophagitis, and Barrett's esophagus are major issues for these patients. Surveillance endoscopies at 5-year intervals in all SG patients and 3-year intervals in patients with Barrett's esophagus are recommended.

PURPOSE: Since 2014, sleeve gastrectomy (SG) has been the most frequently performed bariatric-metabolic operation worldwide (2018: 386,096). There are only a few studies reporting a long-term follow-up (up to 11 years) available today. The aim of this study was to evaluate the long-term outcome of SG with a follow-up of at least 15 years regarding weight loss, remission of associated medical problems (AMP), conversions, and quality of life (QOL). SETTING: Multicenter cross-sectional study; university hospital. METHODS: This study includes all patients who had SG before 2005 at the participating bariatric centers. History of weight, AMP, conversions, and QOL were evaluated by interview at our bariatric center. RESULTS: Fifty-three patients met the inclusion criteria of a minimal follow-up of 15 years. Weight and body mass index at the time of the SG were 136.8kg and 48.7kg/m2. Twenty-six patients (49.1%) were converted to Roux-en-Y gastric bypass (RYGB) for weight regain and gastroesophageal reflux within the follow-up period. Total weight loss after 15 years was 31.5% in the non-converted group and 32.9% in the converted group. Remission rates of AMP and QOL were stable over the follow-up period. CONCLUSION: Fifteen years after SG, a stable postoperative weight was observed at the cost of a high conversion rate. Patients converted to RYGB were able to achieve further weight loss and preserve good remission rates of AMP. SG in patients without the need of a conversion to another bariatric-metabolic procedure may be considered effective. Careful preoperative patient selection is mandatory when performing SG.

OBJECTIVE: Sleeve gastrectomy (SG) has recently become the most commonly applied bariatric procedure worldwide. Substantial regaining of weight or severe reflux might compromise quality of life (QOL) after SG in the long-term follow-up. Long-term data on patients' QOL is limited, even though the persistent improvement in QOL is one of the aims of bariatric surgery. The objective of this study was to present patients' QOL 10 years after SG. METHODS: Of 65 SG patients with a follow-up of ≥10 years after SG who were asked to fill out the Bariatric Quality of Life Index (BQL) and Short Form 36 (SF36) questionnaires, 48 (74%) completed them. This multicenter study was performed in a university hospital setting in Austria. RESULTS: The BQL score revealed nonsignificant differences between the patients with > 50% or < 50% excess weight loss (EWL). It did show significant differences between patients with and without any symptoms of reflux. Patients with < 50% EWL scored significantly lower in 3/8 categories of SF36. Patients suffering from reflux had significantly lower scores in all categories. CONCLUSIONS: EWL and symptomatic reflux impair patients' long-term QOL after SG.

BACKGROUND: Sleeve gastrectomy (SG) has been the most frequently performed bariatric procedure worldwide since 2014. Therefore, it is vital to look at its outcomes in a long-term follow-up based on a large patient collective. Main points of discussion are weight regain, reflux, and patients' quality of life at 10+ years after the procedure. OBJECTIVES: The aim of this study is to present an update of data that have been published recently and, thus, achieve more conclusive results. The number of patients has been doubled, and the length of the follow-up is still 10+ years. SETTING: Multi-center study, medical university clinic, Austria METHODS: This study includes all patients who had SG before December 2006 at the participating bariatric centers. At 10+ years, non-converted patients (67%) were examined using gastroscopy, manometry, 24-hour pH-metry, and questionnaires. Patients' history of weight, comorbidities, and reflux were established through interviews. RESULTS: At 10+ years after SG, the authors found a conversion rate of 33%, an %EWL in non-converted patients of 50.0 ± 22.5, reflux in 57%, and Barrett's metaplasia in 14% of non-converted patients. Gastroscopies revealed that patients with reflux were significantly more likely to have de-novo hiatal hernia. A significantly lower quality of life was detected through GIQLI and BAROS in patients with reflux. CONCLUSION: The authors recommend gastroscopies at 5-year intervals after SG to detect the possible sequelae of reflux at an early stage. Conversion to Roux-en-Y-gastric bypass (RYGB) works well to cure patients from reflux but may not be as efficient at treating weight regain.

BACKGROUND: Laparoscopic sleeve gastrectomy (SG) has become the most frequently performed bariatric procedure worldwide. De novo reflux might impact patients' quality of life, requiring lifelong proton pump inhibitor medication. It also increases the risk of esophagitis and formation of Barrett's metaplasia. Besides weight regain, gastroesophageal reflux disease (GERD) is the most common reason for conversion to Roux-en-Y gastric bypass. METHODS: We performed 24-h pH metries, manometries, gastroscopies, and questionnaires focusing on reflux (GIQLI, RSI) in SG patients with a follow-up of more than 10 years who did not suffer from symptomatic reflux or hiatal hernia preoperatively. RESULTS: From a total of 53 patients, ten patients after adjustable gastric banding were excluded. From the remaining 43, six patients (14.0%) were converted to RYGB due to intractable reflux over a period of 130 months. Ten out of the remaining non-converted patients (n = 26) also suffered from symptomatic reflux. Gastroscopies revealed de novo hiatal hernias in 45% of the patients and Barrett's metaplasia in 15%. SG patients suffering from symptomatic reflux scored significantly higher in the RSI (p = 0.04) and significantly lower in the GIQLI (p = 0.02) questionnaire. CONCLUSIONS: This study shows a high incidence of Barrett's esophagus and hiatal hernias at more than 10 years after SG. Its results therefore suggest maintaining pre-existing large hiatal hernia, GERD, and Barrett's esophagus as relative contraindications to SG. The limitations of this study-its small sample size as well as the fact that it was based on early experience with SG-make drawing any general conclusions about this procedure difficult.

BACKGROUND: With promising short-term results, laparoscopic sleeve gastrectomy (SG) has become the second most frequently performed bariatric procedure worldwide. Aside from a growing number of reports covering up to 10 years of follow-up, only limited data have been published so far on long-term results. OBJECTIVES: The aim of the study was to present a 10-year follow-up for SG. SETTING: University hospital setting, Austria. METHODS: We present the first complete 10-year follow-up of 53 consecutive patients who underwent SG before 2006. In this multicenter study, weight loss success, weight regain, and revisional surgery were analyzed beside Bariatric Analysis and Reporting Outcome System (BAROS) scores. RESULTS: A mean maximum percent excess weight loss of 71±25% (percent total weight loss: 28±15%) was reached at a median of 12 (range 12-120) months after SG. At 10 years, a mean percent excess weight loss of 53±25% was achieved by 32 patients, corresponding to a percent total weight loss of 26.3±13.4%. Nineteen of the 53 patients (36%) were converted to Roux-en-Y gastric bypass (n = 18) or duodenal switch (n = 1) due to significant weight regain (n = 11), reflux (n = 6), or acute revision (n = 2) at a median of 36 months. Two patients died at 3 and 101 months postoperatively, unrelated to SG. A total of 31 patients (59%) suffered from weight regain of 10 kg or more, among them 24 patients (45%) with 15 kg or more, 16 patients (30%) with 20 kg or more, and 7 patients (13%) with 25 kg or more weight regain from nadir. Mean BAROS score was 2.4±2.2 at 10 years follow-up, classifying SG as "fairly efficient." CONCLUSION: Within a long-term follow-up of 10 years or more after SG, a high incidence of both significant weight regain and intractable reflux was observed, leading to conversion, most commonly to Roux-en-Y gastric bypass.

In patients operated on for severe acute pancreatitis (SAP), the factors determining outcome remain unclear. From 1986 to 1998 a total of 340 patients with a diagnosis of SAP and in need of operative treatment were admitted to the intensive care unit (ICU) of a university hospital and a secondary care hospital. The mean APACHE II score on the day of admission was 16.1 (range 8-35). All patients required operative therapy. Among the 340 patients, 270 (79.4%) had to be reoperated: 196 patients (72.6%) underwent operative revisions on demand, and 74 (27.4%) patients had preplanned reoperation. The overall mortality was 39.1% (133 patients). Septic organ failure in 126 patients (37.1%) and myocardial infarction or pulmonary embolism in 7 patients (2%) were the causes of death. The patient's age (p < 0.0002), APACHE II scores at admission (p < 0.0001), presence or development of (single or multiple) organ failure (p < 0.002), infection (p < 0.02) and extent (p < 0.04) of pancreatic necrosis, and surgical control of local necrosis (p < 0.0001) significantly determined survival. SAP that requires surgical treatment is associated with high in-hospital mortality. Surgical control of local necrosis is the precondition for survival. Advanced age of the patient, high APACHE II score at admission, development of organ failure, and the extent and infection of pancreatic necrosis influence the outcome.
