Periampullary cancer
Periampullary cancer is a cancer that forms near the ampulla of Vater, an enlargement of the ducts from the liver and pancreas where they join and enter the small intestine. It consists of:
- ampullary tumour from ampulla of Vater
- cancer of lower common bile duct
- duodenal cancer adjacent to ampulla
- carcinoma head of pancreas
It presents with painless jaundice which may have waxing and waning nature because at times the sloughing of the tumor tissue relieves the obstruction partially.
