Which duct is known as the accessory pancreatic duct?

The accessory pancreatic duct is referred to as the duct of Santorini. This duct is an anatomical variant that drains a portion of the pancreas, typically the superior part, and opens into the duodenum independently of the main pancreatic duct, which is known as the duct of Wirsung. The duct of Santorini can be present in some individuals and is important clinically, especially in cases where the main duct may be obstructed or in variations of pancreatic drainage.

The presence of the duct of Santorini also highlights the complexity of pancreatic anatomy and variations that can affect both diagnostic imaging and surgical procedures. Understanding the role of this accessory duct can be crucial in diagnosing conditions such as pancreatitis or pancreatic tumors, where variations in ductal anatomy may influence symptoms and therapeutic approaches.
