Evaluation of the Outcomes and Performances of the Application of Augmented Reality in Operative Digestive Endoscopy
Virtual reality obtained by the fusion of images can be applied to several fields of medicine
 leading to the so called "augmented reality". Since 2017 investigators have been using a new
 digital angiographic system (Discovery IGS 40, General Electrics), where fluoroscopy can be
 fused with pre-procedural CT o MRI. Specifically the present study aimed at verifying the
 advantages that fusion imaging could bring in EUS-guided drainage of post-pancreatitis fluid
 collection (PFC), i.e. pseudocysts or WON, in terms of more appropriate visualization,
 drainage approach and time needed for resolution.
17 drainages performed with traditional radiology (group 1) were retrospectively compared
 with 14 ones achieved with the fusion approach (group 2). The two population were homogenous
 for age, sex, pancreatitis etiology and indication for drainage whereas PFCs of group 2 were
 larger (663 cm3 vs 437 cm3), more frequently WON than pseudocysts and were treated more
 precociously. As for procedure, in the group 2, thanks to fusion imaging, endoscopists didn't
 need ever contrast media - that was pivotal with traditional radiology - to adequately define
 lesion morphology. LAMS (Axios) stents were placed mainly in group 2, while in group 1 other
 types of stent were used.
