Laparoscopic Training With Laser Guidance Trial

Not Applicable

Completed

• Conditions: Depth Perception

• Registration Number: NCT02407483
• Lead Sponsor: Rigshospitalet, Denmark

Brief Summary

"Laparoscopic simulation training with or without laser visual guidance -A randomised study" which investigates if the use of laser visual guidance can help the novices to learn the laparoscopic skills.

Detailed Description

Background: The loss of depth perception due to working in a three-dimensional space based on two-dimensional images is one of the challenging aspects of laparoscopy compared to conventional open surgery.

Objectives: To examine the effect of laser visual guidance on laparoscopic performance and cognitive load in a simulated setting for novices.

Methods: Randomised Clinical Trial- Laser visual guidance vs. normal 2 D vision.

Outcomes:

Primary outcome: Motor skills performance parameters-movement-time:

Cumulative instrument movement-time for both the right and left instrument for the test session,

Secondary outcome: 2) The overall composite score.

Exploratory outcomes: 3) The NASA Task Load index (NASA-TLX).
