ABSTRACT
Objective: To compare learning and development of skills in participants of the basic workshop of microsurgery between the traditional course and the current one called “chicken model”.
Setting: Microsurgery room of the Experimental Surgery Unit from the Institute of Biomedical Sciences at the Universidad Autónoma de Ciudad Juárez (UACJ), México.
Design: Retrospective study, cases and controls type.
Statistical analysis: Frequencies and odds ratio (OR).
Results: We evaluated 36 students, 19 correspond to the “non-chicken” group and 17 to the “chicken model” group. The end objective was achieved, consisting of performing a termino-terminal anastomosis in arterial or venous vessel of 1 mm by 57% (11/19) of the “non-chicken” group and by 100% (17/17) by the “chicken model” group, with an OR of 12.36 (95% CI, 1.2 to 302). The cost of the traditional model is of 1,200.00 Mx pesos, not including animal facilities costs, and the cost of the “chicken model” is of 501 Mx pesos, and does not require animal facilities.
Conclusion: Teaching and development of microsurgery skills using the “chicken model” were higher than those achieved by the traditional group based on the higher percentage of success, as measured by reaching the end objective and by the reduction in costs.
