机器人辅助手术治疗肝血管瘤技术要点与难点OA

Robotic-assisted hepatectomy has the advantages of being minimally invasive,precise,and controllable in the treatment of giant hepatic hemangiomas,performing particularly well in high-risk vascular anatomy and deep tumor localization.Due to their rich blood supply,massive size,and complex locations,hepatic hemangiomas often pose many technical challenges during surgery,including massive intraoperative bleeding,injury to the hepatic vein or inferior vena cava,and preservation of liver function.Preoperatively,three-dimensional visualization technology is used to obtain precise anatomical information to guide preoperative planning.Intraoperatively,appropriate body positioning and trocar layout are selected.Techniques such as feeding vessel occlusion and hepatic inflow occlusion are comprehensively utilized to effectively control bleeding.Based on the tumor's location,size,and relationship with major blood vessels,enucleation or anatomical resection is reasonably selected.Combined with the improvement of the surgical approach and intraoperative indocyanine green(ICG)navigation,efforts are made to safely and precisely resect the hepatic hemangioma while maximizing the preservation of normal liver parenchyma.
