Abstract
BACKGROUND: Post-hepatectomy liver failure (PHLF) remains a significant complication after hepatic resection. This study aims to determine the rate of PHLF in patients undergoing resection of 3 or fewer segments and analyze the association of PHLF with perioperative characteristics and postoperative complications. METHODS: The American College of Surgeons hepatectomy-targeted National Surgical Quality Improvement Program database was queried for patients undergoing left hemi-hepatectomy or partial resection from 2014 to 2018. The primary outcome was PHLF, defined by ISGLS. Multivariable logistic regression models assessed the association between PHLF, preoperative and operative variables and postoperative complications. RESULTS: Among 7029 patients, 187 (2.7%) experienced PHLF, with clinically significant (grade B/C) PHLF in 1.4%. PHLF was associated with older age, male gender, higher ASA classification, ascites, and elevated SGOT. Preoperative ascites (OR 4.94, 95%CI: 2.45-9.94, p < 0.001) had the strongest association with PHLF. There was no association between PHLF and concurrent colorectal resection, neoadjuvant therapy, or concurrent ablation. Surgical site infection (OR 3.64, 95%CI: 2.40-5.54, p < 0.001), sepsis (OR 3.78, 95%CI: 2.16-6.61, p < 0.001), postoperative invasive procedure (OR 6.92, 95%CI: 4.91-9.76, p < 0.001), and bile leak (OR 4.65, 95%CI: 3.04-7.12, p < 0.001) were associated with PHLF. CONCLUSION: PHLF after minor hepatectomy is rare and associated with signs of preoperative liver dysfunction. The association with infectious complications suggests a multifactorial etiology and provides targets for quality improvement.
