AIM: To present our experience with percutaneous intracorporeal electrohydrolic lithotripsy in the treatment of intrahepatic lithiasis. SUBJECTS AND METHODS: From January 1989 to November 1998, 53 patients with intrahepatic lithiasis were treated with percutaneous intracorporeal electrohydrolic lithotripsy. Twenty-six patients had primary intrahepatic lithiasis. Intrahepatic stones were associated with intrahepatic duct abnormalities in 11 patients, 9 had strictures and 2 had cystic dilatations. Twenty-seven patients had secondary intrahepatic lithiasis formed a biliodigestive bypass in 20 patients. Intracorporeal electrohydrolic lithotripsy was performed under cholangioscopic guidance in all patients. The endoscope was introduced into the biliary ducts through a cutaneobiliary tract in 51 patients, through a cutaneocholecystic tract in one and through a cutaneojejunal tract in one. These tracts were created and gradually dilated in two sessions three days apart. In twenty-two patients stenosis or sharp angulation prevented adequate positioning of the scope which was only successful after balloon dilation or insertion of a stiff wire. RESULTS: Complete clearance of stones was achieved in 49 patients (92%). Biliary or hepaticojejunostomy strictures were successfully dilated with an angioplasty balloon in all patients. Ten patients (19%) had early complications: four had bilomas treated by percutaneous drainage, three had resolutive onset of cholangitis, two had transient arterial hemobilia, and one had a pneumothorax. The mean duration of follow-up was five years. During this period, 5 patients (9%) had recurrent symptoms of biliary obstruction. Among these patients, three (5.7%) had recurrent symptomatic intrahepatic lithiasis, one had a recurrent biliary stricture and one had secondary sclerosing cholangitis. Treatment of recurrent stones was repeated intracorporeal electrohydrolic lithotripsy in two and left hepatectomy in one; recurrent biliary stricture was treated by hepaticojejunostomy and secondary sclerosing cholangitis by antibiotics. CONCLUSION: Intracorporeal electrohydrolic lithotripsy is effective and safe and should be proposed as the first line treatment of primary or secondary intrahepatic lithiasis.

[Behcet's disease associated with pulmonary lesions: a case report].

A 24-year-old man presented clinically confirmed Behcet's disease. He developed thoracic pain accompanied by hemoptyses as a result of thromboses and aneurysm formation in the pulmonary artery. The presence of these aneurysms was suggested by perihilar images on standard radiography, and confirmed by pulmonary arteriography findings and results of histological examination of the operative specimen. Radiological and anatomical evidence of the presence of bronchial endarteritis lesions was also obtained.

[Percutaneous treatment of malignant stenoses of the hilum].

PURPOSE: The endoscopic treatment of malignant hilar obstruction is followed in 70% of the case by infection of undrained biliary sectors. We report the influence of complete biliary drainage on post procedural cholangitis. METHOD: From January 1990 to January 1993 we treated 120 consecutive patients presenting with a malignant hilar obstruction. There were 61 women and 59 men, mean age 65 +/- 7.5 years. The level of stenosis was type II in 45 patients (37%), type III in 18 patients (13%) and above type III in 57 patients (48%). Complete biliary drainage with multiple biliary access was attempted in all patients. Long term internal drainage was achieved by metallic autoexpansive endoprosthesis. RESULTS: Complete drainage was achieved in all patients with type II or type III biliary stenosis. Drainage was incomplete in all patients with biliary stenosis above type III. Early complications were observed in 35% of the patients. Persistent cholangitis, the most frequent complication (22%) was only observed in patients with above type III biliary stenosis. Mortality at 30 days was 17%. Recurrent biliary obstruction was observed in 22% of the patients after an average of 187 days. Median survival was 95 days. CONCLUSION: Complete biliary drainage prevents persistent cholangitis in patients with type II or III biliary stenosis without increasing other complications related to biliary drainage.
