Abstract    Chronic pancreatitis(CP) with an inflammatory mass has been thought of as a precancerous lesion of pancreatic cancer, and it can lead to obstruction of the pancreatic duct, bile duct and duodenum. The CP with mass and pancreatic cancer are difficult to identify from clinical performance, and their prognosis are very different. Once CP with mass has been diagnosed it should be clear that surgical treatment is necessary in order to remove the focus, ease pain, and improve the patient's quality of life. Surgical strategy in CP with mass has been directed at the pancreatic head with a variety of tactics including pancreatoduodenectomy (Whipple procedure with or without pylorus preservation) and duodenum-preserving resection of the pancreatic head (Beger operation and other operations). Pancreatoduodenectomy is preformed in the treatment of CP with mass, not only resection of the pancreatic head mass, lifting the obstruction of the pancreatic duct, bile duct and duodenum, but also removing the potential causes of pancreatic cancer. Pancreatoduodenectomy is a great risk When the pancreatic head mass is large, but the partial head resection can be accomplished with relative safety.
