    Background: There is Little reported information on psychomotor performance in relation to minimal access surgery (MAS).

    Methods: A microprocessor-controlled endoscopic psychomotor tester (the Dundee Endoscopic Psychomotor Tester-DEFT) has been developed to evaluate psychomotor aspects of MAS. Experiments were conducted on 20 medical undergraduates to evaluate accuracy and reliability of the tester.

    Results: The study demonstrated a significant difference between subjects (p < 0.01). It also identified three individuals who enacted 16, 22, and 40 errors while the majority (85%) sustained less errors with a median of 4.5.

    Conclusions: DEFT provides a standard, reproducible, objective real-time scoring system. It identifies individuals who cannot adjust to endoscopic viewing and therefore manipulate from endoscopic images.
