Functional liver reserve parameters predictive for posthepatectomy complications

Area of Science:

• Hepatobiliary surgery
• Surgical oncology
• Liver disease management

Background:

• Posthepatectomy complications remain a concern despite advances.
• Assessing preoperative liver function is vital for predicting surgical risk.
• Injured livers increase the risk of posthepatectomy complications.

Purpose of the Study:

• To evaluate preoperative functional liver reserve tests as predictors of posthepatectomy complications.
• To develop a predictive formula for posthepatectomy complications.
• To improve risk assessment for patients undergoing hepatectomy.

Main Methods:

• A 10-year study of 442 patients undergoing hepatectomy for liver and biliary diseases.
• Multivariate logistic and linear regression analyses were used to identify predictive parameters.
• Analysis included patients with chronic viral liver diseases, obstructive jaundice, and normal livers.

Main Results:

• Fifteen parameters were associated with complications; eight were independent predictors.
• Key predictors included chronic hepatic injury, technetium-99m galactosyl human serum albumin liver scintigraphy clearance index, bilirubin, hyaluronic acid, major hepatectomy, blood loss, operating time, and combined resections.
• A predictive formula incorporated clearance index, bilirubin, hyaluronic acid, and major hepatectomy.

Conclusions:

• A comprehensive formula was developed to predict hepatic complications.
• This formula aids in prospective risk assessment to minimize posthepatectomy morbidity.
• The study provides a tool for better surgical planning and patient management.
