Two hemodialysis patients, one male and one female, aged 46 and 54 years, were treated with preceed respectively for refractory ascites secondary to hepatic cirrhosis and for large polycystic liver. Preceed was decided because of the rapid reappearance of effusion following repeated puncture and albumin infusion, the poor tolerance to ultrafiltration (UF) and the poor nutritional status of the patients, with severe hypoalbuminemia. Abdominal paracentesis was performed on initiation of the dialysis session. Reinjection of the ascites fluid was made into the arterial line, allowing its UF and control of its flow. The procedure was performed whenever necessary, i.e., when inter-dialysis weight gain and ascites volume were high. In both cases, improvement was quickly obtained, with less rapid and less severe reappearance of the effusion and correction of albuminemia. Dialysis sessions with UF were better tolerated. No notable side effect was observed. The first patient was treated for 2 months, when he died of an unrelated cause. The other patient was treated for 6 months and then could be transferred to a dialysis center near her home. Twenty five months after start of dialysis treatment, kidney and liver transplantation were performed in this same patient. After transplantation, reappearance of moderate ascites and oedema is attributed to e degradation of renal function, without liver dysfunction. Five weeks after transplantation, improvement of renal function and ascites regression were noted. Preceed is an effective method of treating refractory ascites in the hemodialysis patient. Compared to classical paracentesis, it has the advantage of good tolerance, patient comfort and moderate cost.
