Millimetric laparoscopic surgery training on a physical trainer using rats.

Purpose: To demonstrate the possibility of laparoscopic technique training and refinement at the millimetric level.

Material And Methods: A physical trainer and Winstar rats were used.

Results: The training system is visually similar to pneumoperitoneum. The laparoscopic technique is perfected in a visual space illuminated by white light, with two-dimensional feedback and at a geometric level that allows for refinement of the technique.

Conclusions: It is possible to refine the technique at this geometric level at a low cost and without requiring laparoscopic equipment. In addition, optics tests indicate the possibility in the short term of refining the laparoscopic technique to the microanastomotic level.
