A Study to Evaluate Safety and Feasibility of Robotic Liver Resection

Condition(s) studied

Investigational drug(s) / intervention(s)

Robotic liver resection: Liver resection using Da Vinci robotic system

Study summary

The robotic surgery system, the most advanced technology in minimally invasive surgery, overcame some shortcomings of laparoscopic surgery and improved the flexibility and precision of liver resection. Several studies have demonstrated that the robotic system was safe and feasible in liver surgery and might be advantageous in complex hepatic vein and hilar dissection, operative bleeding control, and biliary reconstruction. Previous comparative studies found limited evidence for significantly improved outcomes in robotic liver resection (RLR) over laparoscopic liver resection (LLR) or open liver resection (OLR), considering the various degrees of difficulty in liver surgeries.

This study aimed to evaluate safety and feasibility of robotic liver resection, by comparing it with LLR or OLR, and gain veritable and relevant data on the benefits of RLR.

Eligibility

Primary outcome measure(s)

• Postoperative complications — with in 90 days after surgery
  The grades of postoperative complications were recorded following the Clavien-Dindo classification. Partial hepatic dysfunction or hepatic failure, biliary fistula, postoperative hemorrhage, pleural effusion, venous thrombosis, and surgical site infections were recorded.
• Postoperative hospital stay — with in 90 days after surgery
  The days of hospital stay after operation
• Postoperative unplanned reoperation — with in 90 days after surgery
  The unplanned reoperation due to postoperative complications
• Unplanned readmission — with in 90 days after surgery
  The unplanned readmission after discharge due to postoperative complications
