Mucosal oxygen saturation measurements without the presence of bile, with the presence of a bile mixture from the stomach, with a bile mixture from the small bowel and measurements without any of the bile mixtures. The baseline mucosal oxygen saturations did not significantly differ from the mucosal oxygen saturations after the bile had been removed shown as “after bile”. ***p < 2.2 * 10⁻¹⁶
