title: Bloody ascites in a patient after transfer from peritoneal dialysis to hemodialysis.
abstract: A 65-year-old woman with end-stage renal disease (ESRD) presented with bloody ascites. She had been maintained on peritoneal dialysis (PD) for 7 years and had eight episodes of peritonitis. She was eventually transferred to hemodialysis (HD) because of ultrafiltration failure. This was associated with "high" peritoneal transport by peritoneal equilibration test (PET). A period of "peritoneal rest" did not improve PET results. Within a year of transfer to HD, ascites developed, which was hemorrhagic upon evaluation. A computed tomography (CT) scan suggested encapsulating sclerosing peritonitis, which was confirmed upon peritonoscopy. The patient was treated with prednisone and tamoxifen. Encapsulating peritoneal sclerosis (EPS) is a devastating complication of PD. Although it is rare and its development often unpredictable, this case demonstrates several clinical features commonly observed in the condition. These include more than 6 years on PD, a high transporter status, recurrent peritonitis, and the development of blood-stained dialysis effluent (or ascites if PD has been discontinued, as was the case in this patient). The initial presentation is often incipient with vague abdominal pain. Symptoms are progressive, however, and EPS has a high mortality rate, with most patients dying within 1 year of diagnosis, usually from malnutrition and sepsis. Treatment options include systemic immunosuppression and regular peritoneal irrigation after transfer to HD. Response to treatment is more likely to occur in the early inflammatory stage of EPS, when symptoms are nonspecific and imaging is relatively normal. Hence a high degree of suspicion for the diagnosis should be present in patients "at risk" of this condition, as early diagnosis is essential if progressive encapsulation of the abdominal viscera is to be prevented.
