Abstract

This study shows task analysis results for the suturing task in the hybrid rigid scope Natural Orifice Translumenal Endoscopic Surgery (NOTES) cholecystectomy procedure. A hierarchical task analysis tree was constructed from the video recordings of the NOTES procedure and time analysis for the suturing subtask was performed. Results indicate that the 'Pull Suture Through' subtask requires the greatest time (25.4 sec) and the 'Re-bite' subtask had the highest variation (6.6 sec). Intra-rater reliability test (k = 0.68) also showed consistency of the results obtained from the video motion analysis.
