Asynchronous confirmation of anatomical landmarks by optical capture in open surgery

Abstract

Hypothesis: Asynchronous remote telementoring and teleproctoring with anatomical subject matter relevant to surgical procedures is an effective instructional tool for surgical trainees.

Design: A validation model was established to assess the capabilities of current technologies to conduct effective instruction of surgical procedures in a remote location relative to the actual surgical procedure. A total of 23 unilateral thyroid dissections in 13 patients using a laparoscope affixed to a stationary robotic arm were videotaped. Anatomical confirmation was sought for the superior flap, middle thyroid vein, carotid sheath, 2 parathyroids, inferior thyroidal artery, recurrent laryngeal nerve, and superior thyroid pole.

Main outcome measures: Ten surgical trainees reviewed video segments of these 8 anatomical landmarks at a later time after surgery. During observation of the video segments, these physicians were asked to validate the anatomical landmarks on a survey by choosing concur, do not concur, or uncertain. The review panel was also asked to score the images for quality of light, focus (clarity), field range, and contrast.

Conclusion: This study validates the use of asynchronous education with high-quality optical capture for distance education and collaboration in open surgery.
