Abstract

OBJECTIVES: The objective of this study was to evaluate the safety and efficacy of pancreatic extracorporeal shock wave lithotripsy (P-ESWL) in chronic pancreatitis (CP) patients with pancreatic stones after previous pancreatic surgery.
METHODS: This is a single-center study prospectively conducted in pained CP patients undergoing P-ESWL. Patients with a pancreatic surgery history (PSH) were included in the PSH group, and patients without a PSH during the same period were assigned to the control group. The primary outcomes included complications associated with P-ESWL and pain relief. Secondary outcomes included stone clearance and improved quality-of-life scores.
RESULTS: From March 2011 to October 2014, P-ESWLs were performed on 1017 patients (50 in the PSH group, 967 in the control group). No significant difference was observed in the frequency of occurrence of P-ESWL complications between the PSH group and control group (14.0% vs 13.2%, P = 0.877). At follow-up (2.6 years; range, 1.0-4.5 years), pain relief was achieved in 36 patients (75.0%), and 37 patients (77.1%) experienced complete stone clearance. No significant differences were observed between these patients and the matched controls.
CONCLUSIONS: For CP patients who develop painful stones after pancreatic surgery, P-ESWL safely achieves significant pain relief and stone clearance, preventing the need for a repeat surgery.
