title: [Extracorporeal lithotripsy of gallbladder calculi. Tolerability, complications and early results].
abstract: The purpose of this prospective study, conducted on 88 patients, was to assess the tolerance, efficiency and early complications due to a piezo-electric lithotriptor in the destruction of gallbladder stones. One hundred and sixty one sessions were performed in 82 patients. All patients had symptomatic, uncomplicated lithiasis, the diameter of which was less than, or equal to, 30 mm. All patients had less than 7 stones in a functional gallbladder. In 22 patients, the stones were calcified. Lithotripsies were carried out without anesthesia or premedication, except in an 8-year-old child who had to be anesthetized. In 3 cases it was impossible to visualize the gallstones and in 3 other patients, the procedure was discontinued because of abdominal pain. Following the procedure, biliary pain occurred in 20 per cent of the patients. One patient only had biliary colic with transient anicteric cholestasis. Clinical examination, sonography, biological tests were found to be normal in all other patients. Endoscopic sphincterotomy or emergency surgery was never required. Stones were found to be unaltered in 6 patients following 2 lithotripsy sessions. The 76 other patients had fragmentation of their stones. The free gallbladder rate was 15.8 per cent between 0 and 2 months, 24.6 per cent between 2 and 4 months and 51.3 per cent between 4 and 8 months. These results tend to show that the destruction of biliary stones by piezo-electric lithotriptor is efficient and well tolerated. As repeated routine examinations were always negative, the three-day hospitalisation period no longer seems necessary.
