Sheep Liver as a Model for Advanced Laparoscopic Hepatic Resection Training

Area of Science:

• Surgical Innovation
• Medical Education
• Comparative Anatomy

Background:

• Laparoscopic hepatic resection demands advanced surgical proficiency.
• The sheep liver presents anatomical similarities to the human liver, making it a potential model for training.
• Assessing the sheep liver's suitability for advanced laparoscopic hepatic surgery training is crucial.

Purpose of the Study:

• To evaluate the sheep liver as an animal model for advanced laparoscopic hepatic resection training.
• To identify the strengths and limitations of using sheep liver models in surgical education.

Main Methods:

• Ten trainees participated in laparoscopic liver surgery on anesthetized sheep.
• Pre-training CT scans were used for anatomical visualization.
• Post-training questionnaires assessed the realism and effectiveness of the sheep model.

Main Results:

• Sheep liver anatomy, particularly the left portal vein, closely mimics human structures.
• 80% of participants found the procedures realistic, with high ratings for organ properties.
• 80% rated the feasibility of advanced laparoscopic liver surgery on sheep models as very high, with 76.7% reporting very high learning success.

Conclusions:

• The sheep liver is a suitable and effective model for advanced laparoscopic hepatic resection training.
• The model demonstrates high realism and feasibility, contributing to successful surgical skill acquisition.
• Further investigation is recommended to explore specific laparoscopic hepatic techniques within this model.
