A proposed classification enhances understanding of bleeding complications after total pancreatectomy, impacting surgical management.

• 35 patients experienced bleeding complications, highlighting a significant risk.
• The existing ISGPS classification fails to capture all relevant bleeding sources post-total pancreatectomy.

This novel classification offers a more precise framework for identifying and managing hemorrhagic events, aiding surgeons in improving patient outcomes.

• A new severity index correlates with bleeding sources, enhancing clinical decision-making.
