Differences in Perioperative Outcomes Between Right and Left Hepatic Lobectomy

Area of Science:

• Hepatobiliary surgery
• Surgical oncology
• Outcomes research

Background:

• Hepatic resection is a common treatment for liver malignancies.
• Limited data exists comparing outcomes of right versus left hepatic lobectomy for cancer.

Purpose of the Study:

• To compare perioperative mortality and morbidity between right and left hepatic lobectomy in patients with malignant diagnoses.
• To identify risk factors influencing outcomes in liver resections for cancer.

Main Methods:

• Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP) database (2005-2010).
• Inclusion of patients undergoing right or left hepatic lobectomy for malignancy.
• Statistical analysis to determine differences in perioperative outcomes.

Main Results:

• 1680 patients were included in the study.
• Right hepatic lobectomy was associated with a four-fold increase in perioperative mortality compared to left lobectomy (p < 0.0001).
• Right lobectomy patients had significantly higher multi-system morbidity (infectious, pulmonary, cardiac, renal) and increased mortality with advanced age.

Conclusions:

• Right hepatic lobectomy for malignancy is associated with substantially higher mortality and morbidity than left lobectomy.
• Findings are critical for pre-operative risk stratification in liver cancer surgery.
• Further research may explore strategies to mitigate risks associated with right hepatic lobectomy.
