The present data suggest that NIRS is a feasible tool for assessing brain activation during endoscopic surgical tasks, and may have a large impact on the future development of teaching, training, and assessment methods for endoscopic surgical skills.
Evaluation of psychomotor skills in laparoscopic suturing using an electromagnetic motion-tracking system revealed better results for experienced surgeons than for novice surgeons in terms of the time taken, left path length, and right speed of knot-tying. Furthermore, surgical proficiency due to experience can affect surgical dexterity of each hand differently. The present study also demonstrates the efficacy of this system for objective evaluation of laparoscopic suturing skills.
The use of a 3D neuroendoscope improved depth perception and task performance. Our results suggest that 3D endoscopes could shorten the learning curve of young neurosurgeons and play an important role in both general surgery and neurosurgery.
Education and training to maintain medical safety are very important within clinical settings. We have established a training center for endoscopic surgery and we regularly hold a unique training course, which focuses on the development of fundamental skills. One hundred and ninety-four surgeons who participated in our training course were divided into four groups according to their experience in performing laparoscopic procedures. Group 1: 0-19 laparoscopic procedures (n=44). Group 2: 20-49 laparoscopic procedures (n=53). Group 3: 50-99 laparoscopic procedures (n=46). Group 4: more than 100 laparoscopic procedures (n=55). All subjects underwent evaluation for "Lifting & Grasping" using a virtual reality (VR) simulator, LapSim, before and after the training course. The mean efficiency score, time to completion and tissue damage after training were significantly improved after the training as compared with before training. Before training, subjects with greater experience had better scores. However, the only significant difference in the score was between the low experience group and greatest experience group. After training, the score increased in all groups compared with that before training, and there was no significant difference between groups. This study demonstrates the feasibility of using a VR simulator to assess fundamental skills for endoscopic surgery after training. We found that the scores for the task were associated with the level of experience of the surgeons.
The proposed master console design was shown to be feasible for operative neurosurgery based on comprehensive testing. This master console is currently being tested for master-slave control with a surgical robotic system.
Our 2-day training program for active Japanese surgeons is thus considered to be effective; however, continued voluntary training is important and further outcomes assessments are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
