Construct, content and face validity of the camera handling trainer (CHT): a new E-BLUS training task for 30° laparoscope navigation skills

Abstract

competent (p = 0.12) and expert (p = 0.24) participants. All participants agreed that "the CHT is a valid training tool" and that "the CHT should be part of the regular dry laboratory training sessions", assessing both face and content validity. Limitations include the need for assessment of predictive validity. Conclusions The CHT is a valid training tool for 30° laparoscope navigation and thus should be considered as one of the fundamental exercises during basic laparoscopic hands-on training sessions for urologists.Keywords 30° Laparoscopes · Basic laparoscopic skills · Camera handling trainer · E-BLUS · Hands-on training · Laparoscopic camera navigation Abstract Purpose Assessing construct, face and content validity of the camera handling trainer (CHT), a novel low-fidelity training device for 30° laparoscope navigation skills. Methods We developed a custom-designed box trainer with clinically based graphic targets. A total of 117 participants, stratified according to their previous experience (novice, competent, expert), took part to a CHT session and subsequently were asked to fill out a survey to assess the impact of the CHT on their 30° laparoscope navigation skills. Sixty of them were also studied for task performance during a 1-h session, with multiple time measurements. Results All participants, regardless of the previous experience, significantly improved their performance after the CHT session. Regarding construct validity, the mean task performance on the last measurement for novice group was found to be comparable to the mean first attempt of both

Evaluation of a remote-controlled laparoscopic camera holder for basic laparoscopic skills acquisition: a randomized controlled trial

“…Potential gains in skill from laparoscopic exposure would have had limited impact to camera holding ability. Furthermore, the control group creates the conventional environment where an inexperienced assistant often holds the laparoscope [ 13 ].…”

“…Laparoscopy's difficult LC is attributed to the increased workload when compared to open surgery as maintaining challenging physical positions increases stress, physical demand, and reduces performance [8][9][10]. Furthermore, errors made by human camera assistants (HCAs) due to inexperience, miscommunication, tremor, involuntary rotation of the camera's axis, erroneous movements, and fatigue contribute to an unsteady camera image which can also reduce surgical performance [5,9,[11][12][13][14][15][16][17].…”

The European Urology Residents Education Programme Hands-on Training Format: 4 Years of Hands-on Training Improvements from the European School of Urology

“…The EUREP platform has allowed a successful era of E-BLUS and EST-S1 examinations [5,13] that can be a part of a trainee's portfolio and is now successfully conducted in numerous centres across the world. It seems that the EUREP journey has just begun, with new and more exciting courses and curricula on the horizon, such as the lower tract curriculum and advanced laparoscopic and stone treatment courses.…”

Rapid Rehabilitation Surgical Nursing Model in Perioperative Period of Laparoscopic Liver Cancer Resection

“…The tumor was fixed with forceps, and the ligaments of teres hepatis, falciform ligament, triangular ligament and lesser omentum were treated with ultrasonic scalpel according to the situation, and the liver lobe was fully free. Combined with the results of exploration, the appropriate surgical plan was made [10][11].…”
