“…Bright et al analyzed the eye movements of skilled and novice surgeons performing transurethral resection of the prostate in virtual reality using an eye tracker and reported differences in gaze strategies [4]. In actual laparoscopic and microscopic surgery, eye-tracking devices used to analyze the surgeon's gaze points and movement patterns on the monitor revealed clear differences between experts and novices [7][8][9][10]. Eye-tracking devices are also expected to be effective for education in laparoscopic surgery.…”

Introduction:In laparoscopic surgery, it is the assistant who manipulates the laparoscope and manages the field of view. Aim: To develop an endoscopic image processing system that can adjust laparoscopic images as intended by the surgeon without interrupting the surgical procedure. Material and methods: We developed a touchless user interface that displays a magnified image of the endoscope using information of the surgeon's gaze point acquired by an eye-tracking device and the surgeon's voice commands, and evaluated its usefulness during laparoscopic percutaneous extraperitoneal closure (LPEC) of pediatric inguinal hernia. Results: LPEC was performed in 15 clinical cases of pediatric inguinal hernia using this system. In all cases, the internal inguinal ring could be ligated by digitally zooming and moving the endoscopic image by eye tracking and voice command while the scope was fixed. Conclusions: This new touchless user interface with eye tracking shows promise as a support system for laparoscopic surgery.

“…Furthermore, experimental microsurgery offers new psychomotor, perceptual, and visuospatial skills by practicing different techniques in the small field delimited by the view of an optical microscope. This results in advantages in hand-eye and hand-hand coordination, a key part of the minimally invasive surgery that is so prevalent today (18)(19)(20) . Furthermore, the implementation of these programs is included as part of the research activity which, in many cases, is pushed into the background or even ignored.…”

Objective. To describe a basic training program in microsurgery and to analyze the learning curve through the process, including improvement in operating times and functional outcome.Materials and methods. Our learning program included basic, transitional, and experimental models. The experimental model included tail vein cannulation, intestinal resection and anastomosis, dissection, division and anastomosis of the cava and aorta. Wistar rats (66.7% male; 406.9 ± 38.9 grams) were used. The program adhered to the 3R principle and obtained animal welfare committee approval.Results. Mean tail vein cannulation time was 2.4 ± 1.2 minutes. Mean intestinal resection and jejunocolic anastomosis time was 14.8 ± 2.7 minutes and 10.4 ± 3 minutes, respectively. All anastomoses were functionally valid. Mean vessel dissection time was 22.9 ± 7.7 minutes, aortic artery anastomosis was 17.2 ± 7.1 minutes, and vena cava anastomosis was 25.9 ± 7.3 minutes. 66.7% of vena cava anastomoses were functionally valid vs. 88.9% for the aorta. The time required for all procedures decreased after the third attempt, except for vena cava anastomoses, which remained similar in all 9 procedures. Conclusions. Our model demonstrated that the procedures were suitable for trainer progression in terms of surgical time and functional outcome. Microsurgical training would benefit from standardized programs to optimize results.

ResumenObjetivo. Describimos un programa de formación básica en microcirugía y analizamos la curva de aprendizaje a través del proceso, incluyendo la mejora en los tiempos operatorios y en el resultado funcional del procedimiento.Material y métodos. Nuestro programa de aprendizaje incluye modelos básicos, de transición y experimentales. Dentro del modelo experimental se incluyeron: canulación de la vena de la cola, resección y anastomosis intestinal, disección, sección y anastomosis de la cava y la aorta. Se emplearon ratas Wistar (66,7% machos; 406,9 ± 38,9 gramos), el programa se adhirió al principio de las 3R y obtuvo la aprobación del comité de bienestar animal.Resultados. l tiempo medio de canulación de la vena de la cola fue de 2.4 ± 1,2 minutos. El tiempo medio de resección intestinal y anastomosis yeyunocólica de 14.8 ± 2,7 minutos y 10.4 ± 3 minutos, respectivamente. Todas las anastomosis fueron funcionalmente válidas. El tiempo
