Surgeons can now consider double mini upper transversal hepatectomy for colorectal liver metastases involving major veins, previously deemed unresectable.

• This novel approach utilizes peripheral communicating veins to achieve an R0 resection while preserving liver functionality.
• Patients in this study faced no major complications and were discharged by postoperative day 12.

This method expands surgical options for challenging cases, enhancing patient outcomes and potentially improving survival rates.
