Abstrakt: Background and Purpose: We report on an intensive two-day training program on microanastomoses performed on perfused human placenta models. A specific scoring system was elaborated to evaluate the participants' microsurgical skills and report the participants' results.
Materials and Methods: Trainees who attended the Zurich Microsurgery Courses in 2023 were included in the study. Before performing the microanastomoses, each participant received a visual didactic training. Training was made on perfused human placenta models. To perform the microvascular anastomoses, vessels of different diameters were chosen, and 9-0 and 10-0 microsutures were used. The course was structured in two days. On day one, participants practiced microvascular dissection, microsuturing and end-to-end anastomoses, while the second day was dedicated to end-to-side and to repeat the most useful microanastomosis depending on the specialty. A score system for the evaluation of a successful microanastomosis was developed and applied to assess the participants' anastomoses. User satisfaction was measured by means of a survey-based questionnaire.
Results: Fifty-two participants from different institutions, specializations and levels of experience were included. A significant improvement in the overall microsurgical skills of the included cohort was documented (p < 0.005). The initial average score per anastomosis of 3.56 points (SD 0.71) increased to an average of 3.8 points (SD 0.87) at the end of the course. The steepest learning curve was observed in the placement of knots (Δ 0.48 points, p = 0.003) and microvascular dissection (Δ 0.44 points, p = 0.002). Most participants rated the fidelity and importance of the placental microsuturing course as extremely high.
Conclusion: The two-day training program is efficient to teach microvascular dissection and microanastomosis techniques. A significant improvement of participants' microsurgical skills was reported. The human placenta model proved to be a high-fidelity simulator with great user satisfaction.
Competing Interests: Declarations Ethical approval The use of each placenta at the Zurich Microsurgery Course required presence of a written consent for imaging and biologic data use signed by the mother. The trainees at the Zurich Microsurgery Courses participated voluntarily to the study and no consent was signed. Competing interests The authors declare no competing interests.
