Aim of the study: To evaluate the value of Probe Confocal Laser Endomicroscopy (PCLE) in surgery for pancreatic tumor. Methods: Patients who are diagnosed with pancreatic tumor based on preoperative radiographic findings and will undergo radical resection are included in this clinical study. PCLE will be used in surgery to identify tumor is malignant or not, and surgeons will decide procedures of surgery based on outcomes of PCLE. In this present study, clinical trials will be divided into two phases. In the first phase, based on the definitive postoperative pathologic diagnosis, characteristic imaging structures that were collected by PCLE will be identified and primary diagnostic imaging criteria for pancreatic cancer would be developed. In the second phase, this criterion will be used for rapid intraoperative diagnosis of pancreatic cancer and predicting status of resection margin. In addition, accuracy of PCLE will be verified based on postoperative pathologic reports.
