Brief Summary

In the UK alone, obesity is a major health problem with more than one quarter of adults estimated to be obese. Obesity promotes the development of many serious diseases including diabetes, heart disease, kidney disease, and increased risk of some cancers. Patients living with obesity also suffer from significant symptoms that impact their life including shortness of breath, back pain, poor mobility, and poor mental health. Traditional methods to help lose weight include low calorie diets and increased exercise. These may be effective in the short-term, but due to powerful biological mechanisms they are hard to maintain over the long-term and most individuals are unable to achieve normal weight. This means many people may need bariatric surgery that is highly effective at lowering body weight, but it is associated with complications and not all patients will want or be able to undergo surgery. This has led to the development of many new obesity treatments that are completed with an endoscope. An endoscope is a thin flexible tube that has a camera at the end. It is inserted through the mouth and into the stomach and small bowel. There are various procedures that can be done at the time of endoscopy that have been shown to be effective with a low number of side-effects. These are still relatively new compared to more traditional treatments and only a small number of doctors can perform them within the UK. Due to these limitations, the aim of this registry is to obtain real-world information on the safety and effectiveness of these procedures across the UK. The investigators hope over time this will improve the knowledge of clinicians about treating obesity with endoscopy and support future access and funding to these treatments.

Detailed Description

This is a national, multi-centre, prospective, UK registry that aims to determine the safety and efficacy of metabolic and bariatric endoscopic procedures used in the treatment of obesity and related complications. The investigators will do this by determining the effect of primary bariatric procedures (gastroplasty, intragastric balloons (IGB)), revisional bariatric procedures (Transoral outlet reduction endoscopy (TORe), gastroplasty revision), and primary metabolic procedures (Duodenal Mucosal Resurfacing (DMR)), completed by endoscopists within the UK.

The objective of this registry is to collect demographic, procedural and follow-up outcome data on the use of metabolic and bariatric endoscopic procedures in patients with obesity and/or obesity-related complications. This registry will provide real-life outcomes on the use of these novel endoscopic devices from multiple centres participating across the UK to provide longer-term safety and efficacy data. In addition, the registry will enable development of a UK-wide research network to support further research, innovation, and training into metabolic and bariatric endoscopy.

Primary Outcome Measures
NameTimeMethod
Change in glycated haemoglobin (HbA1c; mmol/mol)6-months, 1-, 2-, 3-, 5-years

For primary metabolic procedures

Total body weight loss percentage (TBWL%)6-months, 1-, 2-, 3-, 5-years

For primary or revisional bariatric procedures: Percentage weight loss will be calculated using the following formula: TBWL% = \[(weight at the baseline-weight at the end of time period)/weight at baseline\] x 100

Change in the number and dose of anti-diabetic medications6-months, 1-, 2-, 3-, 5-years

For primary metabolic procedures

Secondary Outcome Measures
NameTimeMethod
Changes in weight (kg)6-months, 1-, 2-, 3-, 5-years
Changes in number and dose of anti-hypertensive medications (n)6-months, 1-, 2-, 3-, 5-years
Change in diastolic blood pressure measurements (mmHg)6-months, 1-, 2-, 3-, 5-years
Changes in triglycerides (mmol/L)6-months, 1-, 2-, 3-, 5-years
Changes in low-density lipoprotein cholesterol (mmol/L)6-months, 1-, 2-, 3-, 5-years
Changes in non-alcoholic fatty liver disease fibrosis score6-months, 1-, 2-, 3-, 5-years

The non-alcoholic fatty liver disease fibrosis score provides a probability score for the presence of hepatic fibrosis. It is based on age, body mass index, impaired fasting glucose, ALT, AST, albumin and platelet count. The range of the score is wide but there are two main cut-offs for prediction of advanced fibrosis (\<-1.455 and \>0.676). Higher scores indicate a higher likelihood of advanced fibrosis.

Inpatient stay (days)6-months, 1-, 2-, 3-, 5-years
Adverse events30-day, 6-months, 1-, 2-, 3-, 5-years
Procedure time (mins)Baseline
Changes in total cholesterol (mmol/L)6-months, 1-, 2-, 3-, 5-years
Changes in glycated haemoglobin (HbA1c; mmol/mol)6-months, 1-, 2-, 3-, 5-years
Changes in number and dose of anti-diabetic medications (n)6-months, 1-, 2-, 3-, 5-years
Changes in aspartate aminotransferase (IU/L)6-months, 1-, 2-, 3-, 5-years
Change in systolic blood pressure measurements (mmHg)6-months, 1-, 2-, 3-, 5-years
Changes in high-density lipoprotein cholesterol (mmol/L)6-months, 1-, 2-, 3-, 5-years
Changes in alanine transaminase (IU/L)6-months, 1-, 2-, 3-, 5-years
Changes in number and dose of anti-obesity medications (n)6-months, 1-, 2-, 3-, 5-years
Changes in Fibrosis-4 Index for Liver Fibrosis6-months, 1-, 2-, 3-, 5-years

The Fibrosis-4 Index for Liver Fibrosis provides a probability score for the presence of hepatic fibrosis. It is based on age, ALT, AST, and platelet count. The range of the score is wide but there are two main cut-offs point for prediction of advanced fibrosis (\<1.3 and \>2.67). Higher scores indicate a higher likelihood of advanced fibrosis.

Changes in health-related quality of life scores (EuroQol-5D-5L)6-months, 1-, 2-, 3-, 5-years

The EuroQol-5D-5L is a quality of life questionnaire that is composed of five questions scored 1-5 that do not have an arithmetic value and a visual analogue scale between 0-100. Participants are simply given a five digit code (e.g. 13455) and a visual analogue score (e.g. 78), which can then be interpreted through reference value sets in the corresponding country.
