Percutaneous cholecystolithotomy

A percutaneous method was used to remove stones from otherwise normal gall bladders, as assessed by cholecystography and ultrasonography. The procedure was performed in a single stage under general anaesthesia, adopting the method and instruments used for one stage percutaneous nephrolithotomy. A Foley catheter was left in the gall bladder and the system checked with contrast at 10 days to ensure free drainage and exclude residual calculi. Seven out of eight patients had a successful percutaneous cholecystolithotomy. An adequate track could not be secured in one man; he had an uneventful cholecystectomy under the same anaesthetic. Follow up at three months of the seven patients showed no calculi and no complications. Percutaneous cholecystolithotomy may prove complementary to extracorporeal shockwave lithotripsy in patients in whom there is difficulty focusing the shock waves on the gall bladder or who have had incomplete disintegration of stones.
