Robotic liver resections show promising outcomes when evaluated with the IWATE criteria, aiding in surgical decision-making.

• Operative times increased with complexity: 148 to 350 minutes; blood loss ranged from 75 to 400 ml (p<0.001).
• Conversion rate was 9.6%, significantly higher in advanced groups (p<0.001).
• Median hospital stay varied by complexity, from 3 to 7 days (p<0.001), with an overall R0 resection rate of 96.3%.

Using IWATE criteria can help surgeons assess risk and anticipate outcomes for patients undergoing robotic liver resection.
