RecruitingProcedureUltra-High Resolution Optical Coherence Tomography in Detecting Micrometer Sized Early Stage Pancreatic Cancer in Participants With Pancreatic CancerThis trial studies how well ultra-high resolution optical coherence tomography works in detecting micrometer sized early stage pancreatic cancer in participants with pancreatic cancer. Ultra-high resolution optical coherence tomography may help to accurately identify pancreatic cancer in resected pancreatic specimens.
