What has NICE said?
There is not enough evidence to be sure about how well an implanted duodenal–jejunal bypass liner works or how safe it is for managing type 2 diabetes. For this reason, it should only be done as part of a research study. NICE may look at it again if more evidence is published.
What does this mean for me?
Your health professional can only offer you this procedure as part of a research study. Details of your procedure will be collected.
Other comments from NICE
NICE said that the procedure is promising but more evidence is needed. It also noted that the safety of the procedure and how well it works may be influenced by ongoing new developments.
