Duodenum, pancreas, and Hepatic Portal Vein Flashcards
Duodenal ulcers
in the posterior wall of the superior part of the duodenum within 3 cm of the pylorus
ulcers could perforate duodenal wall to produce peritonitis or adhere and ulcerate the liver and gall bladder superiorly
rupture of pancreas
caused by accident leading to traumatic rupture of pancreas that may tear the pancreatic duct leaking pancreatic juice that causes digestion of the pancreas and other tissue
pancreatic cancer
cancer of the head often compresses and obstructs the bile duct and/or the hepatopancreatic ampulla causing obstruction, resulting in retention of bile pigments, enlargement of gall bladder, and jaundice
