INTRODUCTION: Evaluate the surgeons’ perceptions after a surgical knot confection using minilaparoscopic instruments (MINI).
METHODS: Thirty surgeons, familiar with conventional laparoscopy (CL), agreed to tie one simple surgical knot in a neoderm model. With no preview instruction, first using CL material and then using MINI instruments of 3mm. Hereafter, willing to compare both experiences, 7 questions were proposed with the following score: three points were given as a pattern answer to all 5mm instruments (CL). When the 3mm material provided a better experience, it received score 4 or 5; when similar, got 3 points, and when worse 1 or 2. The questions focused in if the diameter was proper (1), if the movements were as accurate as wanted (2), if the surgeons felt comfortable tying the knot (3), if the result was expected (4), if the knot was easier to tie (5), if the instruments had proper flexibility (6) and if the material provided superior visualization (7).
RESULTS: In all items MINI, compared to CL, had a higher score. In relation to the adequacy of the diameter scored 4,8; in relation to the movements’ accuracy, 4,5; in comfort while tying, 4,5; in relation to the result, 4,4; in the visualization due the smaller diameter, 4,8. The average MINI’s score was 4,5.
CONCLUSION: The procedure with MINI had an average score 50% higher in comparison to the conventional method. Therefore, Minilaparoscopic instruments can provide a better quality and precision in surgery experience.
