Olympus reviewed the following literature: olympus medical systems corp.(omsc) received a "tips for using spyglass peroral pancreatoscopy and x-ray-guided electrohydraulic lithotripsy for refractory pancreatic stones".This retrospective study was aimed to evaluate the efficacy of peroral pancreatoscopy (pops) and x-ray-guided electrohydraulic lithotripsy (ehl) in treating refractory pancreatic stones.A total of 159 patients with symptomatic chronic pancreatitis and pancreatic stones were treated with combined extracorporeal shock wave lithotripsy (eswl) and/or endoscopic stone lithotomy/endoscopic lithotripsy (el).Of them, 141 cases were successfully completed stone lithotripsy, but 18 patients (refractory cases) had undergone ehl procedures as the second treatment modality.Pops-guided ehl was performed in nine cases, and x-ray-guided ehl was performed in nine cases.The study reported that stone fragmentation was successful in nine (50%) patients: four (4/9) in the pops-guided ehl group and five (5/9) in the x-ray-guided ehl group.Two patients developed mild post-ercp pancreatitis following x-ray-guided ehl.The study concluded that pops and x-ray-guided ehl might be an alternative treatment for refractory stones.But, as ehl can cause severe complications, adequate precautions are necessary for these treatments.This article includes 2 reports: patient identifier (b)(6) for tjf260v.Patient identifier (b)(6) for tjf-240.This is report 1 of 2 for patient identifier (b)(6) (tjf-240) for the following adverse event: the authors reported 2 patients with moderate post-ercp pancreatitis (pep); treatment was conservative management.
