BACKGROUND Since the pioneering work of Jacobson and Suarez, microsurgery has steadily progressed and is now used in all surgical specialities, particularly in plastic surgery. Before performing clinical procedures it is necessary to learn the basic techniques in the laboratory. OBJECTIVE To assess an animal model, thereby circumventing the following issues: ethical rules, cost, anesthesia and training time. METHODS Between July 2012 and September 2012, 182 earthworms were used for 150 microsurgical trainings to simulate discrepancy microanastomoses. Training was undertaken over 10 weekly periods. Each training session included 15 simulations of microanastomoses performed using the Harashina technique (earthworm diameters >1.5 mm [n=5], between 1.0 mm and 1.5 mm [n=5], and <1.0 mm [n=5]). The technique is presented and documented. A linear model with main variable as the number of the week (as a numeric covariate) and the size of the animal (as a factor) was used to determine the trend in time of anastomosis over subsequent weeks as well as differences between the different size groups. RESULTS The linear model showed a significant trend (P<0.001) in time of anastomosis in the course of the training, as well as significant differences (P<0.001) between the groups of animal of different sizes. For diameter >1.5 mm, mean anastomosis time decreased from 19.6±1.9 min to 12.6±0.7 min between the first and last week of training. For training involving smaller diameters, the results showed a reduction in execution time of 36.1% (P<0.01) (diameter between 1.0 mm and 1.5 mm) and 40.6% (P<0.01) (diameter <1.0 mm) between the first and last weeks. The study demonstrates an improvement in the dexterity and speed of nodes' execution. CONCLUSION The earthworm appears to be a reliable experimental model for microsurgical training of discrepancy microanastomoses. Its numerous advantages, as discussed in the present report, show that this model of training will significantly grow and develop in the near future.

Les réseaux d'entreprises formatrices constituent un modèle du système de formation professionnelle en alternance Suisse. Petites et moyennes entreprises peuvent ainsi mutualiser la formation des apprentis. Quelles raisons poussent les entreprises à participer à ce nouveau type d’organisation ? Quels conflits et tensions naissent au sein de ces réseaux ? Les analyses s’appuient sur quatre cas de réseaux et sur la théorie de l'économie des conventions. Ces réseaux naissent d’une pluralité de motifs de participation, source d’insatisfaction dans les entreprises et de conflits dans les réseaux tout au long du parcours de formation.

In the last few years, studies in sport pedagogy have supplied data on the learning conditions provided to young athletes during training sessions and games. From the results of these studies, we learned that, in general, the coach spends most of his/her time observing and organizing rather than teaching. Results also show that the motor engaged time of a participant represents only one third of the training session. Based on the data available, training programs for coaches is one way to improve the learning conditions of youth sports.
