Antecolic bypass with gastric sleeve and duodenal switch. The proximal roux limb makes a rapid leftward turn into a cluster of mildly thickened jejunum in the left mid-abdomen, which on coronal images has a C-shaped configuration with mesenteric edema converging toward the midline. The mucosa is mildly hyperenhancing. The jejunum exits this cluster just before the jejunojenostomy. Small amount of ascites.
