Intraoperativ pancreatoskopi hos patienter med IPMN
Intraoperativ pancreatoskopi hos patienter med intraduktal papillær mucinøs neoplasma (IPMN)
To demonstrate the added value of intraoperative pancreatoscopy in patients undergoing partial pancreatic resection for the treatment of Intraductal Papillary Mucinous Neoplasm (IPMN) as it pertains to detection of discontinuous (skip) lesions in the remnant pancreas; to generate a hypothesis for a subsequent randomized control trial.

Detaljeret beskrivelse
The primary objective of this study is to demonstrate the added value of intraoperative pancreatoscopy in patients undergoing partial pancreatic resection for the treatment of Intraductal Papillary Mucinous Neoplasm (IPMN) as it pertains to detection of discontinuous (skip) lesions in the remnant pancreas. A secondary study objective is to generate a hypothesis for a subsequent randomized controlled trial comparing diagnostic accuracy of intra-operative pancreatoscopy and SpyBite™ with the diagnostic accuracy of intra-operative frozen section in patients undergoing resection
