ABSTRACT
Ampullary tumors mainly manifest as obstructive jaundice and ampullary mass in clinical practice and are difficult to be identified in early stage due to a complex structure of the anatomical site,a deep location,and hidden symptoms.Sometimes a qualitative diagnosis cannot be made.Based on the experience in the treatment of ampullary tumors for many years in our center,this article summarizes the features of ampullary tumors from the aspects of clinical manifestations,diagnosis,treatment,and prognosis,especially the issues regarding imaging evaluation of ampullary tumors,selection of surgical procedure,and prognosis.An early diagnosis is the key to the treatment of ampullary tumors,and early identification and treatment of lesions have great impacts on patients' prognosis.Accurate preoperative imaging evaluation,a professional diagnosis and treatment team,accurate preoperative and intraoperative pathological analysis,and implementation of reasonable therapeutic strategy are the key to patients' recovery.
