Aims:

The new SpyGlass DS system allows to perform cholangioscopy/pancreatoscopy with digital direct vision, and to develop diagnostic and therapeutic measures with a single operator. Our aim is to analyze the indications for use of the Spy-Glass DS system in our hospital, and its diagnostic and therapeutic utility.

Methods:

Retrospective study. We analyzed the indications and usefulness of the Spy-Glass system in 83 patients who underwent to this technique in our center, from December 2015 to November 2017.

Results:

Spy-Glass DS could be performed in 100% of the cases. There were 75 cholangioscopies (90.4%) and 8 pancreatoscopies (9.6%). The indications for its realization in the biliary tract were to evaluate stenosis/intraductal lesions (54.2%), lithotripsy of large stones (20.5%) and assisted guide step (15.7%); whereas in the pancreas were, suspicion of intraductal lesion/dilatation of the Wirsung (4.8%) and lithotripsy of intraductal stones as treatment of pain in chronic pancreatitis (4.8%).

Spy-Glass was diagnosed in 95.1% of patients and also had a therapeutic intention in 47.4% of them. Lithotripsy was performed in 21 patients (25.3%), needing more than one session 18 of them (85.7%), and not being able to perform, in 2 of them (9.5%). The assisted guide step was attempted in 13 patients (15.6%), failing in 2 of them (15.4%).

22 biopsies were performed. Taking as “Standard Gold” the clinical course of the patient, direct vision by SpyGlass DS had a sensitivity 66% and specificity 92% as a diagnostic tool, being the sensitivity and specificity, in the the biopsy of 56% and 100% respectively. The agreement between direct vision and histology was 81%, and it was greater in benign lesions.

Conclusions:

SpyGlassDS is useful as a diagnostic and therapeutic tool in biliopancreatic diseases. The sensibility of the SpyGlass DS detecting malignant lesions was superior to the biopsy, being the specificity of the biopsy reached 100%.
