A single anastomosis in Mini Gastric Bypass

how is there only a single anastomosis in Mini Gastric Bypass, and not two?

Becuase we are joining (1)Jejunum to Duodenum and (2)Jejunum to esophagus/stomach.
Because in Roux en Y gastric bypass sx, there are two anastomosis.

Jejunum os already joined to the duodenum. You don’t create a roux limb in mini bypass

Thank you
