Rationale: In the article, the authors present the relevance of the frequently neglected UN and World Medical Association standard for the documentation of torture related injuries, the Istanbul protocol. Objectives: We aim at summarising the relevant key aspects of this important standard for surgeons in preserving evidence and fulfilling their ethical obligations as medical doctors. We find the instrument clear and relevant and highlight the need of an interdisciplinary approach in the documentation and prevention of torture. Conclusions: The Istanbul protocol is an important standard that should be known and used in clinical practice whenever confronted with possible or alleged sequels to torture an can also improve the understanding of often underrated forensic procedures and the possible contribution of their field for surgeons and other health professionals, not only for forensic experts.
