Cola-Colored Dialysate as a Gastrointestinal Sequelae of Cardiac Surgery in a Patient Who Underwent Peritoneal Dialysis

Figures & data

Figure 1. Peritoneal dialysate. (A) clear dialysate. (B) Cola-colored (brownish-black) peritoneal effluent.

Figure 2. Non-contrast abdominal CT scan. (A) Acute pancreatitis (not hemorrhagic), which was evidenced by increased infiltration around the pancreas with minimal peripancreatic infiltration but without a hyperdense lesion. (B) Left psoas muscle hemorrhage diagnosed by swelling of the left psoas muscle with mixed hyperdense and hypodense cystic foci.
