Abstract
IntroductionComplete tumor resection of primary malignant liver tumors offers the best chance of survival. However, many of these children may experience anemia and failure to thrive. This study analyzes the association of preoperative anemia and nutritional support with outcomes in children undergoing major resection of primary malignant liver tumors. MethodsUsing the National Surgical Quality Improvement Program Pediatric database from 2012 to 2015, children undergoing major liver resections for primary malignant hepatic tumors were selected. Patient demographics, comorbidities, and 30-d outcomes were compared with respect to the presence of preoperative anemia and the need for nutritional support. Outcomes included 30-d postoperative complications, perioperative blood transfusions, and hospital readmissions. Propensity score matching was performed to control for significant confounders. ResultsOne hundred ten children were included, 76 (69.1%) with preoperative anemia, and 36 (32.7%) receiving nutritional support. Anemia was associated with preoperative chemotherapy (P = 0.02) and steroids (P = 0.03). Nutritional support was associated with cardiac (P = 0.01), respiratory (P < 0.01), neurologic (P < 0.01), and hematologic comorbidities (P = 0.02). There were 20 (18.2%) postoperative complications and 6 (5.5%) hospital readmissions. After propensity score matching, there was no difference in complications between anemic and nonanemic patients (P = 0.13). Preoperative nutritional support was associated with an increased rate of complications (P < 0.01). Neither anemia (P = 1.00) nor nutritional support (P = 0.49) were associated with readmissions. ConclusionsThe need for nutritional support is common in children undergoing resection of primary malignant hepatic tumors. Anemia was not significantly associated with postoperative complications. In this study, nutritional support was associated with an increased risk of postoperative complications. The need for nutritional support may warrant special attention to the patient's overall conditioning during operative planning.
