Abstract
The authors report their experience with 24 patients who underwent a variety of percutaneous procedures involving the gallbladder. Twenty diagnostic and 13 therapeutic procedures were performed under sonographic, computed tomographic (CT), or fluoroscopic guidance; these procedures included biopsy of the gallbladder, diagnostic cholecystography, diagnostic aspiration of bile, gallstone dissolution and removal, cholecystostomy for drainage, and gallbladder abscess drainage. The indications for percutaneous cholecystostomy (performed in 11 patients) included relief of hydrops and empyema, gallstone dissolution, mechanical gallstone removal, and drainage for malignant obstruction. Each procedure was successful. There was one complicating episode of cholecystitis and four previously described episodes of vagal hypotension. Bile peritonitis did not occur in any of the patients. The authors discuss the various percutaneous gallbladder procedures and specific technical considerations in performing them.
