Ischemic colitis in chronic intermittent peritoneal dialysis

A 6-year and 8-month-old boy on chronic intermittent peritoneal dialysis for end stage kidney disease presented with severe diarrhea, abdominal distension, cramps, tenesmus and vomiting. Barium enema showed rigidity and irregularity of the mucosa of the sigmoid and distal descending colon, with ‘thumb print like’ appearance, findings compatible with ischemic colitis. The institution of hemodialysis and discontinuation of the peritoneal dialysis resulted in a marked clinical and radiological improvement. Kidney transplantation performed a month later was associated with a complete cure of his intestinal disease.
