Choledochal stenosis and lithiasis caused by penetration and migration of surgical metal clips.

A 71-year-old woman, who had undergone laparoscopic cholecystectomy 1 year previously at our hospital, presented with abdominal pain, high fever, and jaundice. She was diagnosed with choledochal stenosis caused by migration of the clips that were used at the previous operation. At reoperation, the common bile duct was successfully dissected, including the stenotic site, where a metal clip was found to be penetrating the duct wall.

[A study on the effect of combined chemotherapy on Mycobacterium avium complex pulmonary disease].

Annual incidence of Mycobacterium avium complex (MAC) pulmonary disease has been gradually increasing in the last 10 years in Japan, however, the optimal therapeutic regimen for the disease has not yet established. We investigated the effect of our new regimen in twenty seven cases of pulmonary MAC infection without HIV infection, diagnosed according to the American Thoracic Society criteria during the period from January 1996 to October 1997 at our hospital. These patients were treated with rifampicin (RFP), ethambutol (EB) and clarithromycin (CAM) for more than 12 months, together with streptomycin (SM) initially (first 2-3 months), except one patient who was treated for 11 months only.
