AbstractAlthough the safety of hepatic resection has improved, it is still a highly morbid procedure. A retrospective cohort of 375 patients undergoing hepatectomy (2004 to 2012) was done. All procedures were performed by a single surgeon at a tertiary center. To help identify trends over time, two subgroups were identified: Group 1 (n = 195 from October 2004 to December 2010) and Group 2 (n = 180 from January 2011 to November 2012). The two study groups had similar patient characteristics except there were more patients with cirrhosis in Group 2 (10 vs 17%, P = 0.04). A similar number of major hepatectomies was noted. Median estimated blood loss was 400 mL versus 300 mL (P = 0.04) in Group 2. Overall complications were more common in Group 1 (54 vs 45%). Fewer Grade 3 or greater Clavien complications (22 vs 13%, P = 0.04) and fewer hospital readmissions were noted in Group 2 (20 vs 8%, P = 0.002). Morbidity was associated with worse Eastern Cooperative Oncology Group (ECOG) performance status, age older than 60 years, and open surgery. Grade 3 or greater Clavien complications were also associated with age older than 60 years, higher American Society of Anesthesiologists class, and worse ECOG status and median estimated blood less greater than 400 mL. Higher Model for End-stage Liver Disease score and advanced ECOG status were correlated with mortality. Outcomes of hepatic resection improved time despite more complex patient characteristics and an equal number of major hepatectomies being performed. However, worse ECOG performance status was a major predictor of postoperative complications and increased mortality.
