Robotic versus laparoscopic hepatectomy: application of the difficulty scoring system

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Laparoscopic hepatectomy presents challenges.
• A Difficulty Scoring System (DSS) was developed for laparoscopic liver resections.
• Robotic systems may mitigate difficulties in laparoscopic hepatectomy.

Purpose of the Study:

• To assess the applicability of the DSS in robotic hepatectomy.
• To compare robotic and laparoscopic hepatectomy outcomes across different difficulty levels.

Main Methods:

• Prospective collection of clinical data for robotic and laparoscopic hepatectomy patients.
• Grading operation difficulty using the DSS.
• Comparison of perioperative outcomes based on DSS levels.

Main Results:

• Higher DSS correlated with increased complications, blood loss, operation time, and hospital stay in robotic hepatectomy.
• Mean DSS was higher for robotic (4.5) vs. laparoscopic (3.6) hepatectomy.
• Similar outcomes for low/intermediate difficulty; robotic surgery enabled minimally invasive approach for high-difficulty cases.

Conclusions:

• The DSS is a valid tool for assessing robotic hepatectomy difficulty and predicting outcomes.
• Robotic and laparoscopic hepatectomy show comparable results for low-to-intermediate difficulty procedures.
• Robotic surgery expands minimally invasive options for complex, high-difficulty liver resections.
