Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This observational study introduced an new advanced bleeding control strategy during complex liver resection.This newly described "stepwise vascular control" technique was efficacious and feasible to control intra-operative bleeding in complex hepatectomy involving second hepatic hilum and retro-hepatic inferior vena cava.

stepwise vascular control

Before liver parenchymal resection, we performed "total hepatic vascular preparation for occlusion" with portal triad (PT), infra-hepatic inferior vena cava (IIVC), and supra-hepatic inferior vena cava (SIVC) preparation in order. Then we performed step-by-step vascular occlusion according to the individual bleeding situation.
