Role of extracorporeal shock wave lithotripsy in hepato-biliary-pancreatic surgery

Since the early 1980s extracorporeal shock wave lithotripsy (ESWL) has partially replaced major operative procedures in various fields of surgery. In the interest of the patient, it is important to determine the exact role of ESWL in surgery. Comparing our own prospectively followed patients with other patient series, we have tried to assess this role. We treated 133 patients with cholecystolithiasis, 80 patients with choledocholithiasis, and 17 patients with pancreatic stones using a second- generation lithotriptor, the Siemens Lithostar (Siemens, Erlangen, Germany). The results suggest a limited role of ESWL for cholecystolithiasis, in which it is reserved for patients with high operative risk and patients who reject an operation. For choledocholithiasis ESWL seems to become an integral part of the treatment in the elderly patient in whom endoscopic stone removal proved impossible. Finally, ESWL could become a first option for the treatment of intractable pain in patients with chronic calcifying pancreatitis.
