Pancreatic duct -> ampulla of Vater and major duodenal papilla in D2
Which system is the spleen part of?

Since the spleen is often ruptured by blunt trauma to the left hypochondrium, and can lead to fatal internal bleeding, what is a good technique to stop the bleeding when just suturing the spleen up is liable to rupture it further?
Use part of the greater omentum as a pressure bandage - laying it over the laceration and suturing it on. It acts as a peritoneal covering and seals the opening.
Why is hepatosplenomegaly more likely than just hepatomegaly?
The spleen and liver are related - both are supplied by arteries arising from the coeliac trunk, and the splenic vein joins the superior mesenteric vein to form the hepatic portal vein.
Both the spleen and liver enlarge towards the right iliac fossa.
Enlargement of liver restricts blood supply and causes enlargement of spleen.
