RT Journal Article SR Electronic T1 Effect of Continuous Box-trainer Training on Laparoscopic Skills of Surgical Residents: A Prospective, Observational Study JF In Vivo JO In Vivo FD International Institute of Anticancer Research SP 476 OP 482 DO 10.21873/invivo.13102 VO 37 IS 1 A1 KEN IMAIZUMI A1 NOBUKI ICHIKAWA A1 SHIGENORI HOMMA A1 KEIICHIRO YAMAMOTO A1 CHIHIRO ISHIZUKA A1 RYO TAKAHASHI A1 TAKUMU FUKASAWA A1 TAKUMI HAMADA A1 KAZUYA HAMADA A1 HIROKI MATSUI A1 YOICHI MIYAOKA A1 TADASHI YOSHIDA A1 AKINOBU TAKETOMI YR 2023 UL http://iv.iiarjournals.org/content/37/1/476.abstract AB Background/Aim: As opportunities for hands-on surgical training during residency have decreased, off-the-job training before surgery is gaining importance. We developed a training program using a box-trainer for surgical residents. This study aimed to verify the effectiveness of the program. Using task-achievement time, we demonstrated the learning curve through continuous task training and verified the efficiency of our training tasks. In addition, we examined the circularity of the cut circle to evaluate the task accuracy and summarized the questionnaire results. Patients and Methods: A prospective, observational study was conducted at a single center with five trainees from April 2019 to March 2020. The training consisted of four tasks based on the Fundamentals of Laparoscopic Surgery module. The trainees had to achieve expert proficiency time targets. The task-achievement time and circularity of the cut circle were used for objective assessment; subjective evaluation was done using a questionnaire. Results: Although the learning curves of the task-achievement time seemed to reach a plateau between the third and the fifth skills lab, all the trainees achieved expert proficiency times for the three tasks. Circularity of the cut circle tended to be more accurate after training. All trainees perceived an improvement in their skills after the training program. The level of satisfaction of the training program was rated as ‘very satisfied’ or ‘satisfied’. Conclusion: Continuous box-trainer training for 1 year may be effective for improvement in preoperative laparoscopic surgical skills of surgical residents.
