A novel scoring system for evaluating the difficulty of lysis of adhesion and surgical risk at repeat hepatectomy.

The new difficulty scoring system for the lysis of adhesion at ReHx showed good interobserver agreement and reproducibility of the results. Given the strong correlation with postoperative morbidity rate, the present score could be used for evaluating the technical difficulties in ReHx and may offer a reliable measure for estimating the efficacy of anti-adhesion materials in future analysis.
