Difficult method for difficult stones: Mechanical lithotripsy, Şisli Etfal Education and Training Hospital experience
Abstract
Background and Aims:Common bile duct stones were successfully extracted in 85-90% of cases using endoscopic retrograde cholangiopancreatography procedures with balloons and basket catheters. However, endoscopic stone removal becomes challenging and sometimes impossible in the presence of a large, angled or multiple stones. The mechanical lithotripsy method is a procedure used to crush difficult to treat common bile duct stones. We retrospectively analyzed efficacy and safety of mechanical lithotripsy at our single center. Materials and Methods:Between August 2011 and August 2014, mechanical lithotripsy procedures were performed in 18 cases in the Sisli Etfal Education and Training Hospital Gastroenterology Department. Demographic features, laboratory tests, clinical course, procedure type and complications were retrospectively analyzed. Results:Mechanical lithotripsy was performed in 18 patients (Age: 22-68; 11 females, 7 males). In 16 patients, an endoscopic sphincterotomy was performed and the common bile duct was swept with a balloon catheter. While stone fragmentation was being performed with a basket catheter, the entrapped stone was impacted within the mid- common bile duct. A mechanical lithotripteur was used to crush the stone. In two patients with large stones, mechanical lithotripteur was performed after sphincterotomy. Mechanical lithotripsy was successful in 15 (83%) patients; however, in two patients the wire of the mechanical lithotriptor snapped. Unfortunately, an esophageal perforation occurred in one patient. A metallic esophageal stent was placed and the patient recovered in one month. There were no mortalities in our mechanical lithotripsy cases. Conclusion:Mechanical lithotripsy is useful to crush difficult common bile duct stones in routine endoscopic retrograde cholangiopancreatography exams and also as a rescue procedure. It is a difficult procedure that requires considerable technical expertise. The success rate was 70-80% for cases performed by those with experience; it is widely available in many parts of the world. The success rate was 81% in our series, despite some complications.
