Frozen section diagnosis of pancreatic lesions.

Abstract

Frozen sections are useful in conjunction with the impression at surgery for the management of patients with pancreatic lesions. Frozen sections of resection margins were 100% accurate; frozen sections of pancreatic lesions or metastatic sites were accurate in 98.3% of cases. We found an acceptable rate of deferred frozen section (6.6%). The experienced surgeon's impression of malignancy is reliable in cases in which frozen section is deferred or has negative findings.
