The By-Band-Sleeve study has completed. The results will soon be available. We now need to follow up everyone to see how things are in the longer term. We would love you to be involved. Please complete online the ‘Expression of Interest’ consent form.
Note this is for people who were part of the original By-Band-Sleeve Study.
About the By Band Sleeve Study:
What we know and what we don’t know about bariatric surgery
Obesity is an increasing health problem in the UK. Current national guidelines recommend that surgery is considered for people living with obesity. This surgery is known as bariatric surgery. Three of the most common types of bariatric surgery operations are:
- adjustable gastric band (‘Band’)
- Roux-en-Y gastric bypass (‘Bypass’)
- gastric sleeve (‘Sleeve’).
At the moment, health professionals do not know which of these three operations is the most effective for long-term weight loss and improvement of health problems and quality of life.
In January 2016 the By-Band-Sleeve study was selected by the National Institute for Health Research (NIHR) as part of their BIG Challenge campaign to highlight studies which are involved in obesity-related research, from the perspective of the patient and the researchers.
Can I take part?
The By-Band-Sleeve study that includes patients undergoing the three different types of surgery has now completed recruitment and follow up and therefore we are not accepting any new patients for this study. We are currently analysing the results collected from over 1300 participants. If you wish to undergo bariatric surgery you will have to proceed through the standard NHS patient pathway processes.

Study Status
In late September 2019 the By Band Sleeve study completed recruitment and entered the follow up phase during which data on patients was collected through visits to their recruiting hospitals and via online or postal questionnaires. The study reached its target of 1341 patients consented and randomised. The follow up phase ended in September 2022 and the results are currently being analysed.

Covid Update – September 2020
The By Band Sleeve study was in the follow up phase during the UK lockdowns resulting from the Covid-19 pandemic. This meant that the study operations at the coordinating centre never stopped, despite the study team moving to a working-from-home status. Contributing hospitals across the country continued their follow up appointments by telephone and video clinics and the coordination team kept in close contact with our study colleagues across the country throughout the pandemic.
In September 2020 bariatric surgery resumed across some hospital Trusts in the UK. We are in close communication with all of the research teams in these centres to ensure that any remaining surgeries are scheduled to take place as soon as possible. We are also working hard to ensure that face-to-face visits can start again either in hospital or at patients’ homes. We are keen to ensure that this is done in a fully approved and safest way for patients. Further information and updates will be available from your local research team.
