Safety and Efficacy of Extracorporeal Shock Wave Lithotripsy for Pancreatic Stones

June 27, 2023 updated by: Zhaoshen Li, Changhai Hospital
To determine the types, incidence and risk factors of adverse events after pancreatic extracorporeal shock wave lithotripsy (P-ESWL), define the grading criteria of adverse events after P-ESWL, and analyze the efficacy of P-ESWL, which will provide evidence-based medical evidence to guide physicians' clinical practice.

Detailed Description

Currently, pancreatic extracorporeal shock wave lithotripsy (P-ESWL) has become the preferred treatment for pancreatic duct stones. Although some studies had confirmed the safety and efficacy of P-ESWL, the sample size were small and the follow-up period were short. Therefore, investigators designed this study with a large sample and a long follow-up period to clarify the efficacy and safety of P-ESWL, so as to guide clinical work, standardize the diagnosis and treatment process of adverse events.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
the incidence of post-ESWL adverse events
Time Frame: 1 months
An adverse event of P-ESWL is classified as either a complication or a transient adverse event (TAE), depending on severity. Complications are recognized as adverse events needing specific medical intervention and prolonged hospitalization, while TAEs are defined as transient injuries caused by shock waves, which required no medical intervention and do not prolong hospitalization.
1 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
the rate of pancreatic duct clearance
Time Frame: 1 week
Complete clearance: more than 90% clearance of stone volume; partial clearance: 50% to 90% clearance of stone volume; unsuccessful clearance: failure to fragment the stones to less than 3 mm diameter or less than 50% clearance of stone volume.
1 week
