ABSTRACT
The choledocho-pancreatico-duodenal junc-tion is located at the central part of choledocho-pancreatico-duodenal region. During early embryogenetic stage, the primary duodenum develops from the end of foregut and the beginning part of the midgut. The dorsal pancreas, hepatic diverticulum and the ventral pancreas which arises from the basic part of hepatic diverticulum are growing and rotating following the duodenum. During the course, the formations of the choledocho-pancreatico-duodenal region and the central part of choledocho-pancreatico-duodenal junction are complete. The injuries in cho-ledocho-pancreatico-duedenal junction may be caused by metal probe or lithotomy forceps for exploring, dilatating the distal bile duct or taking out the stones from the bile duct. Even if the injuries of choledocho-pancreatico-duodenal junction are deve-loped in a limited scope of several centimeters, several adjacent organs may be involved. Injuries in choledocho-pancreatico-duo-denal junction are hard to be identified during operation and may develop into serious pathological procedures.
