A patient undergoing peritoneal dialysis was admitted with acute peritoneal dialysis-related peritonitis. On the 10th day of intraperitoneal antibacterial therapy, the patient's dialysate developed a green color. Gallbladder perforation was revealed. The patient underwent a conventional cholecystectomy with a preserved peritoneal catheter. There are few cases in the medical literature about green dialysate. In all of them, peritoneal dialysis catheters were removed after cholecystectomy. The present case report shows a patient with an intact peritoneal catheter and with no further complications.
Learning points: Bilirubin measurement in a dialysate helps to differentiate gallbladder perforation from other causes of peritonitis.Urgent diagnostics and treatment is required in patients with changes in dialysate colour.Preservation of perithoneal catheter can be considered after a laparotomy.
