The safety of hepatic resection is well documented, but outcome studies comparing right and left hepatic lobectomy are sparse, especially in the context of malignancy. This study analyzes the differences in outcomes between right and left hepatic lobectomy in patients with malignant diagnoses. All patients undergoing right and left hepatic lobectomies for malignancy were extracted from the National Surgical Quality Improvement Program (NSQIP) database (2005–2010). The data was analyzed to determine differences in perioperative mortality and morbidity between the two groups. A total of 1680 patients who underwent right or left hepatic lobectomy for malignant diagnoses were identified. Patients undergoing right hepatic lobectomy had a four-fold increase in perioperative mortality, compared to left lobectomy (p < 0.0001). Mortality in right lobectomy patients increased incrementally with age, with a 12-fold increase in patients > 81 years of age. Patients undergoing right lobectomy also experienced a statistically significant increase in morbidity involving several systems (infectious, pulmonary, cardiac and renal). The results of our study demonstrate that patients undergoing right hepatic lobectomy for malignancy experience a significantly higher incidence of mortality and multi-system morbidity when compared to left lobectomy. This information will be crucial for pre-operative risk-stratification of patients undergoing hepatic resection for malignancy.
