Laparoscopic retroperitoneal partial hepatectomy offers a safer approach for deep right lobe liver tumors.

• Complete success in 72 patients; conversion to open surgery in 10 cases.
• Mean operative time of 140 minutes, with only 150 ml blood loss; average hospital stay was 8.3 days.

This technique leads to faster recoveries with fewer complications, making it a game changer for surgeons dealing with challenging liver tumors.

• Normal liver function restored within two weeks for all patients; minimal complications like pleural effusion were manageable.
