Abstract

Objectives: We determine the impact of perceptual-motor distortions on multidimensional stress dynamics in novice users of an endoscopic/laparoscopic surgery simulator during performance of a peg-transfer task. Background: Surgeons find the endoscopic/laparoscopic surgery procedure to be more mentally stressful than open surgery. This investigation was designed to identify specific stress dimensions associated with these procedures and to determine the contributions to that stress made by loss of depth information resulting from image-guided views of the surgical field and by disruption of eye-hand mapping. Because stress reactions might depend upon familiarity with these procedures, the study focused upon novice participants. Method: An endoscopic box-simulator featured in surgical training was used in conjunction with the Dundee Stress State Questionnaire, a well-validated multidimensional stress state instrument. A control group (no perceptual distortions) viewed the simulated "sur
