Abstract

Item does not contain fulltext<br />BACKGROUND AND AIMS: Percutaneous cholangioscopy (PC) is more complex and invasive than a transpapillary approach, with the need for a large percutaneous tract of 16 French (Fr) on average in order to advance standard percutaneous cholangioscopes. The aim of this study was to investigate whether percutaneous single-operator cholangioscopy (pSOC) using the SpyGlass(™) DS system is feasible, safe, and effective in PC for diagnostic and therapeutic indications. MATERIALS AND METHODS: The data of 28 patients who underwent pSOC in 4 tertiary referral centers were retrospectively analyzed. Technical and clinical success for therapeutic procedures was assessed as well as diagnostic accuracy of pSOC-guided biopsies and visualization. Adverse events and the required number and size of dilatations were reviewed. RESULTS: 25/28 (89%) patients had a post-surgical altered anatomy. The average number of percutaneous dilatations prior to pSOC was 1.25 with a mean dilatation size of 11 French. Histopathology showed a 100% accuracy. Visual impression showed an overall accuracy of 96.4%. Technical and clinical success was achieved in 27/28 (96%) of cases. Adverse events occurred in 3/28 (10.7%) cases. CONCLUSION: pSOC is a feasible, safe, and effective technique for diagnostic and therapeutic indications. It may be considered an alternative approach in clinical cases where gastrointestinal anatomy is altered. It has the potential to reduce peri-procedural adverse events and costs. Prospective randomized-controlled trials are necessary to confirm the previously collected data.
