Figure 6.

As the scope is positioned anterior to the aorta, the origin of the celiac artery and its bifurcation into two branches — splenic artery and hepatic artery — is seen. The celiac artery and the proximal part of the common hepatic artery are placed in a retroperitoneal location. As the common hepatic artery comes near the upper border of the pancreas, it enters the hepatoduodenal ligament, along with the PV. CA: Celiac artery, PV: Portal vein, HDL: Hepatoduodenal ligament, CHA: Common hepatic artery, SA: Splenic artery
