Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy for treating morbid obesity

What has NICE said?

The evidence about how safe single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI‑S) is for treating morbid obesity shows that there are well-recognised complications but, there is not much good evidence about how well it works. So, it should only be used if extra care is taken to explain the risks, and extra steps are put in place to record and review what happens. More research on this procedure is needed, and NICE may look at it again if more evidence is published.

What does this mean for me?

Your health professional should fully explain what is involved in having this procedure, and discuss the possible benefits and risks with you. In particular, they should explain the uncertainty about the evidence on how likely it is to improve your symptoms and possible complications. You should also be told how to find more information about the procedure. You should only be asked if you want this procedure after having this discussion.

NICE is asking health professionals to send information about everyone who has the procedure and what happens to them afterwards to the National Bariatric Surgery Registry, so that the safety of the procedure and/or how well it works can be checked over time. Your health professional should ask you if details of your procedure can be collected.

Other comments from NICE

NICE said that there can be serious metabolic complications after this procedure, and that people may need another procedure later on.

Your healthcare team

A healthcare team experienced in managing morbid obesity should decide who should be offered the procedure. It should only be done by surgeons with specific training in the procedure, in centres with expertise in treating morbid obesity.
