Usefulness of Thiel-Embalmed Cadavers for Training in Organ Procurement

Abstract

The number of brain-dead donors has been increasing; however, the opportunity for young surgeons to experience deceased donor surgeries is extremely limited, especially in many Asian countries including Japan. Deceased donor surgeries require unique surgical skills and knowledge; however, it is difficult to provide on-the-job guidance and education. Therefore, cadaver training is meaningful and suitable for the training of deceased donor surgeries. Thiel's embalming method (TEM) provides natural coloration, flexibility, and tissue plasticity, and is widely used for cadaver surgical training. In this study, we evaluated the usefulness of Thiel's embalmed cadaver training for organ procurement surgery. Each trainee performed hepatectomy, pancreatectomy, and nephrectomy using conventional open techniques. Faculty experts of transplantation surgery and organ procurement took attendees through surgical steps. After the procedure, all participants were asked to complete a voluntary, anonymous survey, consisting of a 10-point satisfaction scale, to evaluate their perceptions of the training. A total of 33 gastrointestinal surgeons participated in the training program for procuring the liver, pancreas, and kidneys. In the questionnaire administered to the participants, the evaluation was generally satisfactory, with an average of 9.1 points on the 10-point scales. Some participants expressed that Thiel-embalmed cadavers are more suitable for training on organ procurement compared with animals used in wet-lab training. We conclude that organ procurement training in human cadavers preserved by TEM is useful and suitable for practicing deceased donor organ procurement, especially in countries where deceased donors are not common, as in Japan.
