Abbreviations: PLD, polycystic liver disease; PKD, polycystic kidney disease; LT, liver transplantation; LR, liver resection; CT, computed tomography; MRI, magnetic resonance imaging; US, ultrasonography; KT, kidney transplantation; ICU, intensive care unit; POD, postoperative days; INR, prothrombin index; GI, gastrointestinal; HV, hepatic vein; and IVC inferior vena cava. Objective: In an attempt to refine the indications for liver resection (LR) for highly symptomatic polycystic liver disease (PLD), we focused on the characteristics, technical difficulties, postoperative outcome, and long-term follow-up of PLD patients who underwent either LR or liver transplantation (LT). Methods: Since 1995, among 72 patients with massive hepatomegaly, 45 patients underwent LR associated with contralateral cyst fenestration whereas 27 underwent LT associated with simultaneous kidney transplantations in 23. The LR group was characterized by absence of end-stage renal insufficiency, absence of ascites, and better nutrition status. In the LR group, the volumetry of the spared noncystic parenchyma was preoperatively assessed whereas pathological analysis focused on fibrosis and vascular congestion. Results: After LR, the mortality was nil and overall morbidity was 71%, including biliary leak in 20% and ascites in 42%. Persistent and massive ascites was observed in 8 patients who have undergone extensive resection and had significantly more frequently fibrosis on the analysis of their resected surgical specimens (P = 0.002). A volume of the remnant noncystic parenchyma less than 30% and the presence of vascular changes on the specimen were associated with higher risk of complications. The 5-year survival was 95% and among the 43 survivors, after a mean follow-up of 41 months, 36 (83%) patients stated that they were satisfied, with complete relief of symptoms in 30 (70%). After LT, the postoperative mortality was 15% and the overall morbidity was 85%, including 12 patients who required reoperation. Severe complications were more frequent in the presence of denutrition and preoperative ascites. The 5-year survival was 85% and after a mean follow-up of 36 months all survivors had complete relief of symptoms due to hepatomegaly. Conclusions: In case of massive hepatomegaly from PLD without end-stage renal failure, LR should be considered first when preserved remnant liver volume represents at least 30% of the total volume liver in the absence of vascular changes or fibrosis.
