Intraoperative Endoscopic Ultrasound for Pancreatic Cancer

Summary

Nowadays pancreatic cancer is one of the deadliest oncological pathologies. The only effective curative tool is the surgery. Before the intervention, an endoscopic ultrasound is performed on the patient to carry out the biopsy of the main tumor. In this study, the echoendoscopie will be extended to lymph node staging away from the surgical field in order to implement a simple classification of lymph nodes, based on non-invasive ultrasound criteria. This would facilitate the location and qualification of peripancreatic lymph nodes and distant from the tumor, and therefore the staging of the tumor.
