Strategy for prophylaxis and control of bleeding during laparoscopic hepatectomy
In recent years, laparoscopic hepatectomy has increasingly become more established as a treatment option for various liver diseases, thanks to the rapid development in laparoscopic and minimally invasive techniques. However, it remains a challenging procedure because of difficulty in control of bleeding at the resection surface. The effective prevention and control of intraoperative bleeding is the basic premise for the completion of successful laparoscopic hepatectomy. At present, there are a variety of methods that have been used for prevention and control of intraoperative bleeding, including hepatic vascular occlusion, application of various devices for liver parenchymal transection, laparoscopic ultrasonography, controlled low central venous pressure, and resection surface treatments. Here, the authors review the current applications of these methods.
