MIB69 Cellvizio confocal endomicroscopy system for characterising pancreatic cysts

Cellvizio is a confocal laser endomicroscopy (CLE) system with a fibre-optic probe for real-time imaging of tissues. It is designed for use as an adjunct to the standard endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) procedure, to characterise pancreatic cysts and provide additional information to help guide therapeutic decisions. The evidence summarised in this briefing comes from 2 feasibility and 3 pilot studies with a total of 138 adult patients. The diagnostic accuracy for Cellvizio was reported to be between 71% and 87% in 3 studies compared with histopathology, EUS-FNA or a committee consensus. In 2 studies, images were successfully obtained in all patients. In another study, images were successfully obtained in most (17 of 18) patients. The device was used to identify and validate new diagnostic criteria for pancreatic cyst types in 4 studies. The numbers of safety incidents in 2 Cellvizio studies were higher than reported in a previous EUS-FNA-only study.
