Diagnostic and therapeutic single-operator cholangiopancreatoscopy with SpyGlassDS™: results of a multicenter retrospective cohort study.

SOC with SpyGlassDS™ became a new standard for the diagnosis of indefinite biliary lesions and therapy of large bile duct stones. The diagnostic yield of SOC-guided biopsies facilitated a definite diagnosis in most cases and should be improved by standardized biopsy protocols. SOC-guided interventions allowed removal of large biliary stones by SOC-guided lithotripsy. The complication rate of 13.2% can be considerably reduced by use of a single-shot antibiotic treatment.
