Hepatobiliary pathology in hemodialysis patients: an autopsy study of 78 cases.
Necropsy findings of hepatobiliary system from 78 patients with end-stage renal disease maintained on hemodialysis are reported. Ninety percent of the patients exhibited some abnormalities. Multiple abnormalities often coexisted in each patient. Hepatomegaly was found in 50% of the patients and could be attributed to a discernible cause in all but two of the affected patients who had isolated hepatomegaly. Hepatic congestion was also prevalent and was complicated by fibrosis, cardiac cirrhosis, and centrilobular necrosis and hemorrhage in some patients. This was associated with chronic fluid overload, hypertension, and/or cardiovascular disease in the affected patients indicating the importance of adequate control of these factors. Mild periportal hepatic fibrosis, fatty metamorphosis, triaditis, hemosiderosis, and cystic changes were also seen with some frequency--the latter were associated with polycystic kidney disease and were complicated by massive intracystic hemorrhage and abscess formation, each in one patient. Chronic active hepatitis was found in three patients and was associated with chronic HBs antigenemia in one patient and presumed non-A, non-B infection in two. Nearly 22% of the patients showed either cholelithiasis at autopsy or before cholecystectomy due to complications. Significant negative findings included lack of acute viral hepatitis, silicone hepatosis, and recently described focal anoxic lesions associated with erythrocyte sludging. In conclusion, the present study has demonstrated the spectrum of hepatobiliary pathology in a large group of patients with end-stage renal disease maintained on hemodialysis.
