Figure 3 Phenotype-driven treatment algorithm for difficult main pancreatic duct stones. Proposed clinical algorithm for difficult pancreatic duct stones, incorporating patient symptoms, stone and duct features, access anatomy, local expertise, and expected treatment burden to guide selection among endoscopic retrograde cholangiopancreatography extraction, pancreatoscopy-guided lithotripsy, extracorporeal shock wave lithotripsy-centered therapy, stricture-focused decompression, and early surgical consultation. MPD: Main pancreatic duct; CT: Computed tomography; ERCP: Endoscopic retrograde cholangiopancreatography; ESWL: Extracorporeal shock wave lithotripsy.
