Chyloperitoneum is characterized by the presence of triglyceride-rich chylomicron particles in the peritoneal cavity, which causes the peritoneal effluent to appear “milky”(1). The potential pathogenesis of chyloperitoneum involves the interruption of lymphatic drainage from the gut to the main lymphatic trunks(1). This could occur spontaneously – particularly in neonates(2)- or as a result of tuberculous peritonitis(3), various medications (4–6), lymphoma or radiation therapy, liver cirrhosis, diet(7)or abdominal trauma(1).
Diagnosis and Management
The diagnosis is suspected by the presence of a milky peritoneal outflow in the absence of any other signs or symptoms of peritonitis. Confirmation rests on positive Sudan black stains of the supernatant for fat, and dialysate triglyceride levels exceeding plasma triglyceride concentrations. Therapy consists of elimination of the causative condition, temporary cessation of PD, temporary bowel rest, and/or a diet of medium-chains fatty acids(1,4,5).
