Department of Surgery,Peking Union Medical College Hospital,Chinese Academy of Medical Sciences,Beijing 100730, China Corresponding euthor:ZHAO Yu-pei, E-mail:zhao 8028@263.net Abstract Because of the special Anatomical location and diversity of pathology, surgical treatment of pancreas head mass lesions should be individual. For the solid mass,it is important to distinguish chronic pancreatitis with mass in the head of the pancreas with pancreatic carcinoma before operation process. Pancreaticoduodenectomy is the classical operation for pancreatic head carcinoma. There is still no consensus for the widely application of PPPD,ELND and VR, so they can be Selected conditionally. Duodenum-preserving pancreatic head resection has certain superiority in the treatment of pancreatic head mass lesions. Do not have too much emphasis on the pathological results of the atypical cases. Pancreaticoduodenectomy is acceptable and worthwhile for these patients.For the cystic and cystic-solid mass in the pancreas head, the operation process should be based on tumor size, location, pathological type and so on.External and internal drainage,tumor enucleation, duodenum-preserving pancreatic head resection,segmental resection,Whipple procedure are the usual applied operation process.Inside drainage should be avoided for the pancreas cystic tumors.
