Peritoneal dialysis in end-stage renal disease patients with preexisting chronic liver disease and ascites.

PURPOSE: Hemodialysis in patients with chronic liver disease and ascites may be complicated by intradialytic hypotension, limiting the amount of ultrafiltration and resulting in massive ascites. Successful maintenance peritoneal dialysis (PD) has not been previously reported as an alternative to hemodialysis in this population.

PATIENTS AND METHODS: Nine patients with chronic renal failure, chronic liver disease, and tense ascites prior to beginning PD are described. All chronic PD catheters were placed percutaneously by the nephrology staff. Seven patients were maintained primarily on continuous ambulatory peritoneal dialysis, whereas two were on intermittent peritoneal dialysis.

RESULTS: PD catheters were placed without serious hemorrhage or bowel injury. PD provided adequate clearance and volume maintenance for each patient. Fifteen episodes of peritonitis occurred in 18 patient-years of PD. All episodes of peritonitis were successfully treated with intraperitoneal antibiotics without catheter removal. Only one patient had a decline in the serum albumin level of 0.5 g/dL or more during the course of chronic PD. Three of the nine patients are still alive and on PD for durations of 18 to 24 months. One patient insidiously developed sclerosing peritonitis after 8 years on PD and is now on hemodialysis, and another patient switched to hemodialysis because she was no longer able to care for herself or to manage her PD. Four patients died while maintained on PD; three deaths were due to complications of liver failure within the first 4 months of PD and the fourth was due to empyema after 4 years of PD.

CONCLUSION: PD can be used successfully to treat chronic renal failure in patients with chronic liver disease and ascites when the liver disease itself is not rapidly fatal. PD may be better tolerated than hemodialysis and perhaps should be the renal replacement treatment of choice in these patients.
