Establishment and evaluation of a training course in advanced laparoscopic surgery based on human body donors embalmed by ethanol-glycerol-lysoformin fixation.

Background: Education of clinical anatomy and training of surgical skills are essential prerequisites for any surgical intervention in patients. Here, we evaluated a structured training program for advanced gynecologic laparoscopy based on human body donors and its impact on clinical practice.

Methods: The three-step training course included: (1) anatomical and surgical lectures, (2) demonstration and hands-on study of pre-dissected anatomical specimens, and (3) surgical training of a broad spectrum of gynecological laparoscopic procedures on human body donors embalmed by ethanol-glycerin-lysoformin. Two standardized questionnaires (after the course and 6 months later) evaluated the effectiveness of each of the training modules and the benefits to surgical practice.

Results: Eighty participants took part in 6 training courses using a total number of 24 body donors (3 trainees/body donor). Based on a 91.3% (73/80) response rate, participants rated high or very high the tissue and organ properties of the body donors (n = 72, 98.6%), the technical feasibility to perform laparoscopic surgery (n = 70, 95.9%), and the overall learning success (n = 72, 98.6%). Based on a 67.5% (54/80) response rate at 6 months, participants rated the benefit of the course to their daily routine as very high (mean 80.94 ± 24.61%, n = 53), and this correlated strongly with the use of body donors (r = 0.74) and the ability to train laparoscopic dissections (r = 0.77).

Conclusions: This study demonstrates the technical feasibility and didactic effectiveness of laparoscopic training courses in a professional and true-to-life setting by using ethanol-glycerol-lysoformin embalmed body donors. This cost-efficient fixation method offers the option to integrate advanced surgical training courses into structured postgraduate educational curricula to meet both the technical demands of minimal invasive surgery and the ethical concerns regarding patients´ safety.
