Objective:  To assess the efficacy and safety of the removal of pancreatic duct stones by a combined modality approach in patients with pancreatic ductal lithiasis and recurrent abdominal pain.

Design:  Retrospective review with a mean follow-up of 19 months (range, 1 to 56 months).

Setting:  A tertiary care, private community hospital with a university affiliation.

Patients:  The records of patients who presented to the hospital or who were referred with recurrent abdominal pain and who were demonstrated to have pancreatic ductal lithiasis between 1989 and 1994 were reviewed. ductients were assessed by their clinical response to pancreatic duct stone extraction by a variety of therapeutic interventions.

Results:  Fifteen patients were included in the study. One patient was excluded from analysis because of a concurrent choledochocele. Two patients required operative decompression and stone extraction for endoscopically inaccessible stones. Six patients were treated with endoscopic management alone, and six were treated with a combination of extracorporeal shock wave lithotripsy and endoscopic stone retrieval. Twelve patients had complete clearance of the pancreatic duct. One patient had a stone that was not removed, but adequate pancreatic ductal decompression was achieved. The remaining patient had incomplete clearance of pancreatic stone fragments following extracorporeal shock wave lithotripsy but had adequate ductal drainage. No patient has required further therapy or hospitalization for abdominal pain. No complications occurred as a result of any intervention in this study.

Conclusions:  A multidisciplinary combined modality approach is a safe and effective method for extracting pancreatic duct stones in symptomatic patients. Stone extraction and reestablishment of adequate ductal drainage appear to relieve symptoms in some patients.(Arch Surg. 1995;130:375-380)
