Figure 1.
The Roux limb ex-vivo is shown in (A) with the defunctionalized Roux limb to the left, the proximal limb at the top, and the distal limb at the bottom. (B) illustrates the gross appearance of an acetic acid induced jejunal mucosal ulcer after 3 days. At 3 days (C), the proximal limb exhibits the highest luminal pressure and the slowest ulcer healing (n=10 and 15 respectively, P<0.05 for each), compared to the distal limb. The Roux limb also exhibits higher pressure and slower healing (n=10 and 15 respectively, P<0.05 for each) than the distal limb.
