When lymph nodes were greater than 12 mm 10 mm 8 mm or 6 mm in longo or short-axis diameter the nodes were considered metastatic. Detection and removal of paraaortic sentinel nodes by means of a laparoscopic gamma-probe and real-time imaging with a portable gamma-camera is a successful.

When lymph nodes were greater than 12. To diagnose PAN metastases we used the following diagnostic criteria. Wang asked for CT-guided biopsy.
