Abstract
We performed a retrospective study of 44 patients who underwent right or extended right hepatic lobectomy to determine the incidence and significance of hypophosphatemia after major hepatic resection. The postoperative serum phosphate level (measured as inorganic phosphorus) dropped in all 44 patients studied. Profound hypophosphatemia (less than 1.0 mg/dl) was significantly (p less than 0.001) associated with the frequent development of major postoperative complications (cardiorespiratory, five cases; infections, four cases; hemorrhage, one case; and liver failure, one case). Factors such as extent of liver resection, blood loss, blood or plasma transfusion, postoperative bilirubin level, and preexisting liver diseases showed no significant correlation with the nadir inorganic phosphorous level. Use of aluminum-containing antacids caused a further drop of the serum values (p less than 0.05). Early phosphorous replacement showed a significant protective effect (p less than 0.05), with higher serum levels and fewer major complications. These observations affirm the importance of frequent monitoring and replacement of phosphate after major hepatic resection.
