Pancreatoscopy guided lithotripsy for difficult pancreatic duct stones: Evidence and treatment selection in chronic pancreatitis

Table 2 Current cholangiopancreatoscopy/pancreaticobiliary scope platforms relevant to pancreatic duct therapy

Manufacturer	Platform/processor	Reusable or single-use	Typical access route	Approximate outer diameter/working length	Working channel	Diagnostic/therapeutic versions or accessories	Pancreatic relevance/caveat
Boston Scientific	SpyGlass DS/DS II Digital Controller with SpyScope DS II catheter	Single-use digital catheter-based cholangiopancreatoscope	Duodenoscope-assisted transpapillary access	Approximate distal tip 10.5 Fr/3.5 mm; working length approximately 214 cm; requires large duodenoscope channel	Approximately 1.2 mm channel	Diagnostic visualization; compatible with EHL and LL fibers/probes within channel constraints	Most commonly reported modern platform; duct caliber and downstream stricture can limit passage
Boston Scientific	SpyGlass Discover Digital Catheter	Single-use digital catheter designed for surgical/endoscopic pancreaticobiliary use	Short-access or operative access routes depending on setup	Approximate distal tip 10.5 Fr/3.5 mm; working length approximately 65 cm	Approximately 1.2 mm channel	Diagnostic and therapeutic pancreaticobiliary visualization with compatible accessories	May be relevant to altered access or operative settings; pancreatic duct use depends on local indication and equipment
Micro-Tech	eyeMAX cholangiopancreatoscopy platform	Single-use digital scopes in different outer-diameter/channel configurations	Duodenoscope-assisted transpapillary access	Reported configurations include approximately 3.2-3.9 mm outer diameter; working length depends on model	Reported channels approximately 1.2-2.0 mm depending on model	Diagnostic and therapeutic versions/accessory compatibility varies by region	Larger channel may aid accessory passage but may require larger duct/access; verify local regulatory availability
Olympus	CHF-B260/CHF-B290 mother-baby pancreatocholangioscopes	Reusable fiber/video cholangiopancreatoscopes	Mother-baby system through duodenoscope	Approximate outer diameter around 3.4 mm for older systems; working length/model-specific	Approximately 1.2-1.3 mm channel depending on model	Diagnostic visualization and selected therapy with compatible accessories	Reusable mother-baby systems require two operators and are less widely used than single-operator platforms
Olympus	CHF-BP260 ultra-slim pancreatocholangioscope	Reusable ultra-slim fiber/video scope	Mother-baby or special access routes	Approximate outer diameter around 2.8 mm; working length/model-specific	Approximately 0.8 mm channel	Primarily diagnostic or limited therapy due small channel	Smaller diameter may help narrow ducts but restricts lithotripsy accessories
CenterPoint Systems	Dragonfly Pancreaticobiliary Scope and Digital Controller	Single-use digital catheter and controller	Duodenoscope-assisted transpapillary access	FDA-cleared specifications report approximately 3.6 mm outer diameter and 139 cm working length	Working channel approximately 5.1 Fr	Diagnostic and therapeutic pancreaticobiliary endoscopy with compatible accessories	Newer platform; published pancreatic stone outcome data remain limited
Tangent Endoscopy	Tangent Single-Use Digital System	Single-use digital catheter and controller	Pancreaticobiliary endoscopy via compatible endoscope/access route	FDA-cleared specifications report approximately 3.3 mm shaft outer diameter and 650 mm working length	Approximately 1.6 mm channel	Diagnostic and therapeutic pancreaticobiliary use with compatible accessories	Newer platform; real-world pancreatic lithotripsy evidence is limited
