Integration of 3D Volumetry, Portal Transection and In Situ Split procedure: a new surgical strategy for inoperable Liver Metastasis

Introduction The purpose of this study was to report on the feasibility of integrating 3D preoperative volumetry, portal vein transection and in situ split procedure. A 54-year-old female with now resectable colorectal liver metastasis (CRLM) (segments III, IVb, V-VIII) underwent a two-staged procedure. Methods Segment III resection, right portal vein transection and an in situ split procedure (first stage) after 3D volumetry based on CT data and a right trisegmentectomy (second stage) were performed. RO resection of metastases was achieved, and the postoperative course was uneventful. Conclusion The proposed strategy seems to be a promising method to achieve higher resectability rates in CRLM patients
