Trends and Safety in Revisional Bariatric Surgery in Italy

ObesityMorbid5 more

Background: Revisional bariatric surgery (RBS) represents a further solution for patients who experience an inadequate response following initial bariatric surgery or significant weight regain following an initial satisfactory response. Studies including the follow-up of patients with complications after RBS are still lacking. Aim: to analyze the trend, mortality, and complications at 30 days after RBS in Italy. Secondary aim: 30-day readmission rate, reoperations for any reason related to bariatric surgery. Design: longitudinal, prospective, multicenter study. Time interval: 10 months October 2021 - July 2022). Setting: 11 high-volume bariatric centers of the Italian National Health Service (SSN), university hospitals, hospitals, accredited private centers. Methods: All patients undergoing RBS from 01.11.2021 through 31.04.2022 will be enrolled in a prospective, online database, registering indications, technique, mortality, intraoperative and perioperative complications, readmission for any reason. All participating centers follow the same preoperative work-up protocol, indications, informed consent, and postoperative follow-up, including scheduled telephone and outpatient visits after 7, 15 and 30 postoperative days. Inclusion criteria: revisional procedures; no concomitant procedure, but hiatal hernia repair; age >18<60 years; compensated comorbidities; informed consent including COVID-19 addendum; adherence to specific admission, in-hospital and follow-up protocols. Patients undergone RBS during 2016-2020 will be considered a control group. The study will not involve any modification of the usual protocols. Statistical analyze: to make qualitative quantitative comparison regarding clinical and anthropometric factors between the two study groups (2021-22; 2016-20), the z-test for two proportions and t-test (two-tailed) will be used, respectively. The significance is fixed at 0.05 and all analyzes will be performed with the SPSS v.27 software. Expected results: enroll about 500 patients to obtain information on the safety of RBS and the current trends in Italy.

Management of Sleeve Gastrectomy Failure Using Single-anastomosis Metabolic Surgery

ObesityObesity1 more

Sleeve gastrectomy (SG) has become the most commonly performed weight loss surgery, accounting for 60% of all bariatric operations worldwide. While technically easier with less side-effects and nutritional risks than other operations, SG is also associated with a higher risk of failure (20 to 40%). In such case, the most effective option consists in adding an intestinal bypass called the Biliopancreatic Diversion with Duodenal Switch (BPD-DS). This surgery is, however, technically challenging and yields a significant risk of complications, nutritional deficiencies or gastro-intestinal side-effects. Recently, a simplified version of the Standard DS, called Single-Anastomosis Duodenoileal Switch (SADI-S) was endorsed by surgical societies as one of the approved bariatric procedures. There is currently no prospective or randomized data to support the effectiveness of this new procedure, especially as a revisional approach. The Overall Objective of this randomized controlled trial project is to establish the clinical benefits of the SADI-S as a revisional surgery after SG, while also considering critical issues related to sex and gender. The investigator Overall Hypothesis is that the SADI-S represents a relevant revisional option for weight loss and metabolic recovery in women and men suffering from severe obesity who had a previous SG. The investigator propose to address the following research question. Research Question: What are the clinical effects of SADI-S compared to standard DS when used as a revisional procedure after SG, in patients with obesity? Participants who need revisional surgery after SG will be enrolled in a prospective, randomized, double-blind (patient-evaluator), non-inferiority trial comparing SADI-S vs DS. The primary outcome will be 12-month excess weight loss. Secondary outcomes will be perioperative complications, risk of malnutrition, quality of life and gastrointestinal side effects. The investigator hypothesize that SADI-S offers similar weight loss compared to standard DS, but a lower risk of complications and nutritional deficiencies. With the increase in the number of bariatric operations performed worldwide and the recent endorsement of the SADI-S as a regular procedure, reliable clinical data are urgently needed. The present proposal will directly address this knowledge gap.

Evaluation of SaCo Videolaryngeal Mask Airway in Morbidly Obese

Morbid ObesityAirway Complication of Anesthesia2 more

SaCo videolaryngeal mask airway is a novel third generation supraglottic device allowing for continuous observation of entrance to larynx via inserted in special channel videoscope connected with cable with external monitor. In obese patients airway management can be difficult so use of new devices that improve safety and potentially efficacy of airway management is indicated. In prospective observational study the SaCo VLM will be evaluated in terms of maintaining airway patency and effectiveness of intubation through it's lumen in morbidly obese scheduled for elective general surgery under general anesthesia.

Evaluation of Different Methods to Measure Muscle Mass and Strength in a Population With Class II/III...

ObesityMorbid

Rationale: Weight loss therapies should aim to reduce fat mass while preserving both muscle mass and muscle strength. Consequently, there is a need for validated methods to measure muscle mass and strength. Current methods are either expensive and require trained technicians, or have not been validated in populations with class II/III obesity (BMI > 35 kg/m2). In our previous studies (MUST-MOP and MUSCLE study), we have validated the use of ultrasound (US) for the measurement of lean mass (a proxy for muscle mass) in a population with obesity. These studies showed that the use of US for the measurement of lean mass was feasible, reliable and valid. The aim of the current study is to validate the use of US for the measurement of lean mass after weight loss in a population of bariatric surgery patients. Objective: Primary objective: To assess the validity of US to measure lean mass after weight loss in a population of bariatric surgery patients. Secondary Objectives: To assess de differences in lean mass between DXA and US in this study compared to the MUSCLE-study. To assess how the lean mass has changed after bariatric surgery and the effects of lean mass on total weight loss and resolution of comorbidities To assess whether the change in lean mass has an effect on serum levels of markers for muscle mass. Study design: This study is an observational follow-up study of the MUSCLE study and will take place in the Centre Obesity Northern-Netherlands (CON) at the Medical Centre Leeuwarden (MCL). Study population: The population will consists of participants, who have participated in the MUSCLE study and have received bariatric surgery at the CON / MCL. Main study parameters/endpoints: The main parameters of this study are: lean mass measured by DXA and US. The main endpoint of this study is the validity of the US measurement of lean mass compared to DXA. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are no direct benefits for the participants. However, the results of this study can help to further validate the ultrasound as a cheaper and more accessible method to measure muscle mass. This can potentially be used in standard clinical care to assess muscle mass of patients during weight loss. • The additional time investment: during first year follow-up appointment approximately 30 minutes. The risks of most test are minor, even the small amount of radiation exposure, which means the risks and burden of this study outweigh the potentially obtainable knowledge.

Dairy Lipids and Cardiometabolic Risk

Morbid Obesity

It is a randomized parallel arm intervention study in adults with severe obesity. The objective is to demonstrate that within a dietary handling for weight loss, the daily ingestion during 3 months of whole dairy products enriched with milk polar lipids or whole dairy products decreases to a greater extent fasting plasma apolipoprotein B concentrations than the daily ingestion of low-fat dairy products (control group). Metabolic parameters will be assessed before and after the 3-month intervention, both at fasting and in postprandial period after the consumption of standardized meals.

The Poor Responders Study

Bariatric Surgery CandidateObesity3 more

Obesity and type 2 diabetes are major causes of illness and premature death worldwide and their incidence is increasing rapidly. Bariatric surgery is considered as the "gold-standard" surgical treatment for both conditions. However, not all patients do equally well after surgery and indeed the weight loss experienced by patients undergoing bariatric surgery can vary. As such when patients are seen after bariatric surgery in clinic they fall in one of the following two categories: Good responders: this is the majority of patients who lose the expected amount of weight based on the published studies. Poor responders: this is a small group of patients who either lose less than the expected amount of weight after bariatric surgery or lose the expected amounts of weight early after surgery but then regain a substantial proportion of the weight they have lost. The so-called "poor responders" are exposed to all the risks of the operation and do not benefit from the weight loss as much as good responders. This study would therefore like to investigate the physiological factors that distinguish poor from good responders before, and after bariatric surgery. The study team hypothesizes that compared to good responders, poor responders exhibit: a smaller degree of fullness sensation after a meal, a lower energy expenditure after a meal, and genetic changes (single nucleotide polymorphisms) that predispose the poor responder to development of obesity. In addition, the study team hypothesizes that poor responders exhibit: lower gut hormone secretion after a meal and are less sensitive to the physiological action of gut hormones compared to good responders and that this difference in gut hormone secretion and response to gut hormones prior to bariatric surgery can be helpful to predict response to bariatric surgery.

Bariatric Surgery and Pharmacokinetics of Buprenorphine

ObesityMorbid

Changes to gastric pH, gastric emptying time, gastrointestinal transit-time or the pre-systemic metabolizing effect of enzymes secreted in the mucosa may all alter the pharmacokinetics of medicines. These factors are potentially influenced by bariatric surgery. Little is so far known about how gastric bypass and sleeve gastrectomy impacts the biological availability of medication. In this study the pharmacokinetic effects of bariatric surgery on buprenorphine are investigated.
