Research Summary
Obesity is an increasing health problem in the UK and which is predicted to worsen. It is associated with many health problems that can shorten a person's life span and impair quality of life. Current national guidelines recommend that surgery is considered for the very overweight (morbidly obese) or for those remaining obese after trying other options. In the UK and worldwide the two most commonly performed operations are laparoscopic adjustable gastric banding (’BAND surgery’) and laparoscopic gastric bypass (’BYPASS’). Both lead to weight loss, but they are associated with different problems. In the short term there are varying complications and inconvenience relating to the operation. In the longer term there are different outcomes relating to weight regain, symptoms and side effects of surgery. This study (BY-BAND) is a randomised trial of 724 patients in eight hospitals to compare the effectiveness, cost effectiveness and acceptability of BAND and BYPASS surgery. The process of randomisation will mean that participants have an equal chance of having either procedure, so a fair comparison between them can be made. The first phase (in two hospitals) will test the feasibility of recruitment and optimise information for patients to maximise trial recruitment. It will establish a core set of clinical outcomes to use to evaluate the surgery for morbid obesity. The second stage (in 8 hospitals) will recruit the full sample and follow-up all participants for at least three years. We will compare the effects of BAND and BYPASS surgery three years after randomisation on weight loss, a wide range of symptoms and aspects of quality of life. We will also examine patients’ detailed experiences during follow-up, nutritional outcomes, short and long term surgical complications and NHS value for money.
