Comprehensive evaluation of liver resection procedures: surgical mind development through cognitive task analysis

Area of Science:

• Surgical Education
• Minimally Invasive Surgery

Background:

• Liver resection presents significant challenges for surgical trainees.
• Cognitive task analysis (CTA) is a method for deconstructing complex expert tasks, particularly those demanding substantial cognitive effort.

Purpose of the Study:

• To compare open and laparoscopic liver resection techniques using CTA and video-based coaching.
• To decompose the liver resection task into fundamental components relevant to surgical principles.

Main Methods:

• Cognitive task analysis (CTA) was employed to dissect the liver resection procedure.
• Video-based coaching was used to illustrate key steps in both open and laparoscopic liver resection.

Main Results:

• The liver resection task was decomposed into exposure, working plane management, and target processing.
• Specialized techniques like hanging maneuvers and hepatic vein looping were demonstrated via video for both surgical approaches.

Conclusions:

• Familiarity with laparoscopic anatomical orientation can facilitate the transition for surgeons experienced in open liver resection.
• Factors such as patient tolerance, instrumentation, and team expertise influence surgical strategy selection.
• Integrating surgical principles with paramedical factors aids trainees in understanding expert decision-making and optimizing surgical strategy.
