| Discussion|| |
The meeting successfully brought together experts from two different fields of pathology which have both increased in importance over recent years: transplantation and digital pathology. Results of the meeting are summarized in [Table 1]. As many of the speakers explained, there is a global upsurge in transplantation activity that has required health-care systems and pathologists to respond to this increasing demand. The overarching message of the conference was that digital pathology can play an important role in addressing some of these needs (e.g., telepathology and image analysis) and at the same time can advance the field of transplantation. In digital pathology, there have been considerable technological advances that have permitted these imaging systems to be effectively used in daily clinical practice and for cutting-edge research. Several of the speakers corroborated this message by sharing their personal experience, demonstrating the reliability and safety of whole-slide imaging for routine diagnostic practice. Given the benefit of having immediate access to an expert second opinion, some of the speakers pointed out that teleconsultation for frozen section during transplantation is a perfect application of digital pathology. However, issues that still need to be tackled include cost, legal questions, lack of training, and complex workflow in laboratories. Moreover, digital pathology can also be leveraged to advance the field of transplantation by promoting standardization, protocols, guidelines, and further research. The take-home message from the conference was that we can anticipate exciting times in the next few years as these two fields of pathology continue to grow and complement each other.
