Background: Post-operative serum transaminases have been proposed as possible early predictors of morbidity after liver resection. This study aimed to verify the clinical value of post-operative serum transaminases., Methods: Clinical data from 2001 to 2016 in a single non-academic referral HPB center were collected from a prospectively held database. Post-operative day 1 serum aspartate transaminase (AST) and alanine transaminase (ALT) were tested for their relationship with post-operative major morbidity, defined by a Clavien-Dindo score 3 or higher, and mortality., Results: For this analysis, 371 patients were included, including 149 (40%) undergoing major liver resections. In total, 17% of the patients developed major morbidity. Stepwise logistic regression demonstrated that AST, and not ALT, is an independent predictor for major morbidity (p = 0.017). The probability of major morbidity significantly increased with increasing AST values. A threshold value of 242 U/L was found to be predictive for one or more major complications., Conclusions: In this study, post-operative serum AST on day 1 was a predictive factor for major morbidity after liver resection. For patients with low AST value, early discharge could be considered. However, because of the substantial inter-individual variability of AST values, more studies are needed to translate these results into clinical practice., (© 2021.

Introduction: Unplanned readmission is a common event after liver resection, and it is a burden for both patients and healthcare policy makers. This study evaluates the incidence of and reasons for unplanned readmission after liver resection, in order to identify possible preventable causes. Methods: In this single-center cohort study, data from patients who underwent liver resection for both malignant and benign indications from 2001 to 2016 at our institute were collected from a database with prospective data. Readmissions were analyzed for their reasons and risk factors. Patients with general complaints with no specific complications were categorized as failure to thrive. Results: In 406 patients, the readmission rate was 11.6%. Most patients were readmitted because of failure to thrive (35%), deep and superficial surgical site infection (28%), or cardiopulmonary complications (15%). A multivariate analysis revealed that unplanned readmission was associated with the occurrence of complications during index admission—with an odds ratio of 4.69 (CI 2.41–9.12, p < 0.001). Conclusion: Readmission occurs in more than 1 in 10 patients after liver resection, and it is associated with a complicated course during index admission. One-third of readmissions occur because of failure to thrive and might be preventable. Future research in strategies to reduce readmission rates should focus on both the prevention of complications during index admission and programs at the interface between primary and secondary care.
