Chylous ascites due to bile duct tumour in a patient receiving automated peritoneal dialysis.

Sir, Bacterial peritonitis is the most common cause of cloudy dialysate seen in patients with peritoneal dialysis (PD) [1]. However, the differential diagnoses include sterile ‘allergic’ peritonitis, excess fibrin and haemoperitoneum (e.g. menstrual blood loss). A rare cause is chyloperitoneum [2] caused by leakage of chyle. For the first time, we present a case of chyloperitoneum in a PD patient secondary to an obstructive bile duct carcinoma.
