What is a single-anastomosis duodeno-ileal bypass?
The sleeve gastrectomy can be combined with a different kind of single-anastomosis (join) bypass which does not expose the stomach and oesophagus to the same levels of bile as the so-called “mini bypass”. This means the risks of stomach and oesophageal cancer, which may be elevated by a mini bypass, are avoided while still achieving much of the same weight loss.
This procedure is potentially suitable for patients who have fallen away from good eating habits and regained the weight which their sleeve had originally helped them lose. Research is also being conducted into this procedure as a primary operation (in conjunction with a sleeve) for patients with a very high body mass index, as in theory it is more potent than a sleeve alone.
We currently consider this procedure as an option for sleeve revision, but as further evidence emerges, it may become more common as a primary procedure.
