Endoscopic therapy and extracorporeal shock wave lithotripsy (ESWL) are recommended as the first choice in treating pancreatolithiasis. Endoscopic therapy is generally performed using endoscopic pancreatic sphincterotomy (EPST). Herein, we report our experience implementing a treatment protocol, combining endoscopic therapy and ESWL without EPST, for pancreatolithiasis. The inpatient treatment plan was performed every 3 months with a set number of sessions of ESWL with endoscopic pancreatic stenting (EPS) implanted or replaced. Finally, treatment was terminated when the stone was removed after implantation of a 10-Fr stent and crushed to approximately 3 mm or after spontaneous stone discharge. Eight patients were included in this study; the median time to stone disappearance was 208.5 days. The median number of inpatient treatment cycles, endoscopic retrograde cholangiopancreatography, and ESWL sessions was 2.5, 3, and 3, respectively. No serious adverse events were observed in all patients. Therefore, combining ESWL and EPS without EPST can safely treat pancreatolithiasis.
