Transferencia de habilidades prácticas desde el laboratorio a cirugía in vivo utilizando el sistema robótico Avatera: Estudio experimental / Transfer of acquired practical skills from dry lab into live surgery using the Avatera robotic system: an experimental study

Objetivo Evaluar la transferencia de habilidades adquiridas en el laboratorio a un entorno experimental real para realizar cirugía robótica. Material y métodos Se utilizó un modelo experimental in vivo. Seis residentes y fellows de urología; dos R2 sin exposición previa a cirugía laparoscópica (Grupo 1), dos R4 con exposición intermedia (Grupo 2) y dos fellows formados en cirugía laparoscópica (Grupo 3) realizaron reimplantes ureterales distales, pieloplastia, y nefrectomía radical en tres cerdos hembra. Previamente a realizar los procedimientos, cada participante completó entre 10 y 14 h de formación en cirugía robótica en laboratorio hasta adquirir habilidades para realizar maniobras quirúrgicas básicas (sutura, corte y paso de agujas). Las variables analizadas fueron completar o no con éxito los procedimientos, el tiempo de consola y el tiempo para realizar las maniobras solicitadas y. presencia de complicaciones. Resultados Los tres grupos completaron con éxito todos los procedimientos excepto la pieloplastia, que no la completó el Grupo 1 por sangrado de la vena renal. El Grupo 3 logró un tiempo de consola más corto para todos los procedimientos y para los pasos quirúrgicos por separado, seguido por el Grupo 2. El grupo más lento para completar los procedimientos y los pasos fue el Grupo 1. Conclusiones A pesar de que es necesaria evidencia clínica al respecto, nuestros resultados sugieren que los procedimientos urológicos con asistencia robótica y los pasos más difíciles técnicamente podrían realizarse de manera segura y efectiva después de un entrenamiento adecuado en el laboratorio bajo la supervisión de un mentor.

Objective To evaluate the transfer of the practical skills of robot-assisted surgery acquired in the dry-lab into a real live experimental setting for performing upper and lower urinary tract surgeries. Material and methods An in vivo experimental study design was utilized. Six urology trainees and fellows; two 2nd year trainees with no previous exposure to laparoscopic surgery (Group 1), two 4th year residents with medium exposure to laparoscopic surgery (Group 2) and two fellows trained to perform laparoscopic surgeries (Group 3) performed ureteral reimplantation into the bladder, pyeloplasty, and radical nephrectomy on three female pigs under general anesthesia. Prior to performing the requested procedures, each participant completed 10-14 hours dry-lab robotic training acquiring skills in basic surgical tasks, such as suturing, cutting and needle passage. The recorded variables were the successful completion of the procedures, the console time, and the time to perform different steps and major complications. Results All procedures were completed successfully by all groups except the pyeloplasty by Group 1 which was complicated by bleeding from the renal vein, and the procedure was abandoned. Group 3 achieved shorter console time for all successfully completed procedures and for separate surgical steps compared to all groups, followed by Group 2. The slowest group for all procedures and steps analyzed was Group 3. Conclusions Although further clinical evidence is needed, the robotic-assisted urological procedures and the most challenging steps could be performed safely and effectively after proper training in the dry lab under mentor supervision according to our study.

Transfer of acquired practical skills from dry lab into live surgery using the avatera robotic system: An experimental study.

OBJECTIVE: To evaluate the transfer of the practical skills of robot-assisted surgery acquired in the dry-lab into a real live experimental setting for performing upper and lower urinary tract surgeries. MATERIAL AND METHODS: An in vivo experimental study design was utilized. Six urology trainees and fellows; two 2nd year trainees with no previous exposure to laparoscopic surgery (Group 1), two 4th year residents with medium exposure to laparoscopic surgery (Group 2) and two fellows trained to perform laparoscopic surgeries (Group 3) performed ureteral reimplantation into the bladder, pyeloplasty, and radical nephrectomy on three female pigs under general anesthesia. Prior to performing the requested procedures, each participant completed 10-14 h dry-lab robotic training acquiring skills in basic surgical tasks, such as suturing, cutting and needle passage. The recorded variables were the successful completion of the procedures, the console time, and the time to perform different steps and major complications. RESULTS: All procedures were completed successfully by all groups except the pyeloplasty by group 1 which was complicated by bleeding from the renal vein, and the procedure was abandoned. Group 3 achieved shorter console time for all successfully completed procedures and for separate surgical steps compared to all groups, followed by Group 2. The slowest group for all procedures and steps analyzed was Group 3. CONCLUSIONS: Although further clinical evidence is needed, the robotic-assisted urological procedures and the most challenging steps could be performed safely and effectively after proper training in the dry lab under mentor supervision according to our study.
