Precise hepatectomy guided by minimally invasive surgery: A novel strategy for liver resection

摘要

Liver resection has been established currently as an effective and standard treatment for patients suffering from both benign and malignant hepatobiliary diseases. Although substantial improvement in perioperative mortality rate and morbidity resulting from appropriate candidates selection, advanced surgical techniques and enhanced perioperative care, hepatectomy is still burdened by about 5% mortality rate and some lethal postoperative complications, especially postoperative liver insufficiency and failure. Various approaches have been advocated to minimize stress and insult on patients due to operative procedures. It becomes important to preserve remnant hepatic function as much as possible to improve the outcome of hepatectomy. Minimally invasive concept and fast track surgery are crucial breakthrough in the natural history of surgery and have been employed in liver resection. To safely and ccurately perform hepatic resection, owing to our experiences with recent advances in surgical techniques and perioperative administration for liver resection, a novel strategy, "precise hepatectomy" originating from minimally invasive surgery has been developed, which includes precise preoperative planning, sophisticated intraoperative techniques and careful postoperative management. This strategy is characteristic by involvement of minimally invasive concept in overall therapy, from preoperative assessment to postoperative care, optimization of a series of advanced techniques and proper employment of surgical instruments in light of actual individual information. However, further prospective studies, especially randomized controlled trials in high volume centers, remain essential to compare the safety and therapeutic efficacies between precise hepatectomy and conventional surgical procedures.
