In order to create the Roux-limb, the jejunum is divided 15 cm beyond the ligament of Treitz by using an Endo GIA II stapler (US Surgical), 45 mm long with 3.5 mm staples. In addition the mesentery is also divided with a Endo GIA II stapler, but this time using the vascular load (45 mm length, 2.0 mm staples). This maneuver will facilitate mobilization of the small intestine through the mesocolon. A rubber drain is sutured to the jejunum to help with the pulling.
