Olympus reviewed the following literature titled " extracorporeal shock wave lithotripsy and endoscopic pancreatic stenting without pancreatic sphincterotomy for the treatment of pancreatolithiasis: a case series." literature summary: this study discussed endoscopic therapy and extracorporeal shock wave lithotripsy (eswl) as recommendations for the first choice in treating 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.A total of 8 patients were involved in this case series with a median age of 69 years.The median time from initial treatment to target stone disappearance was 208.5 days (range, 4¿452).Symptoms improved after the initial inpatient treatment in all patients.The median follow-up time after stone disappearance was 950 days, with two cases of stone recurrence.Mild pancreatitis occurred twice in ercp and once in eswl.Three cases of stent dislocation were observed; dislocation that did not meet the severity grade occurred twice of the three cases.Hence, combining eswl with eps without epst can treat pancreatolithiasis safely.Type of adverse events/number of patients: -npdc (nasopancreatic drainage catheter) obstruction (moderate) - 1 patient (patient #3, age 54, male) - treated with an additional endoscopic pancreatic stenting to place a 7-fr npdc.-pancreatitis (mild) - 1 patient (patient #2, age 68, male) - treatment included a post-procedure medical consultation or an unplanned hospital admission or prolonged stay for less than or equal to three nights.-pancreatitis (mild) - 1 patient (patient #4, age 69, male) - treatment included a post-procedure medical consultation or an unplanned hospital admission or prolonged stay for less than or equal to three nights.-stent dislocation (moderate) ¿ 1 patient (patient #4, age 69, male) ¿ treated with unplanned anesthesia/ventilation support during conscious sedation, unplanned hospital admission or prolongation of stay for 4-10 nights, icu admission for 1 night, a transfusion, a repeat endoscopy, or interventional radiology.-stent dislocation that did not meet the severity grade - 2 cases.The author did specify there was no malfunction of any olympus device but was unclear whether any adverse events were related to the devices.This literature article requires 8 reports.The related patient identifiers are as follows: - patient #2 (age 68, male): tjf-q290v: (b)(6) for adverse event (pancreatitis).Tjf-260v: (b)(6) for adverse event (pancreatitis).Pr-110q-1: (b)(6) for adverse event (pancreatitis).Pbd-v803w-06: (b)(6) for adverse event (pancreatitis).- patient #4 (age 69, male): tjf-q290v: (b)(6) for adverse event (pancreatitis).Tjf-260v: (b)(6) for adverse event (pancreatitis).Pr-110q-1: (b)(6) for adverse event (pancreatitis).Pbd-v803w-06: (b)(6) for adverse event (pancreatitis).This medical device report is for patient identifier (b)(6).
