Efficacy and Safety of Robotic Surgery vs. Open Surgery for Hilar Cholangiocarcinoma: A Comprehensive Review.

Hilar cholangiocarcinoma, a rare and aggressive bile duct malignancy, presents significant challenges in surgical management. Traditionally treated with open surgery, the emergence of robotic surgery has introduced a new dimension to surgical approaches for this condition. This review aims to systematically compare the efficacy and safety of robotic surgery versus open surgery for hilar cholangiocarcinoma. We conducted a comprehensive review of the literature, including clinical studies, case series, and comparative analyses of robotic and open surgical techniques. Data on oncological outcomes, functional recovery, survival rates, complications, and cost-effectiveness were extracted and analyzed to provide a detailed comparison of the two surgical approaches. Robotic surgery offers several potential advantages over open surgery, including reduced intraoperative blood loss, smaller incisions, and shorter recovery times. However, it requires specialized training and has a higher initial cost. Open surgery, while more established and broadly practiced, remains associated with longer recovery periods and higher complication rates. Oncological outcomes, such as R0 resection rates and survival, appear comparable between the two approaches, though robotic surgery may offer improvements in functional recovery and postoperative quality of life. Both robotic and open surgery have their merits in the treatment of hilar cholangiocarcinoma. Robotic surgery presents promising benefits in terms of reduced invasiveness and improved recovery, while open surgery continues to be a reliable and well-established option. The choice of surgical approach should be guided by patient-specific factors, surgeon expertise, and institutional resources. Further research is needed to refine surgical techniques and establish long-term outcomes, which will aid in optimizing treatment strategies for this challenging malignancy.
