[Transparieto-hepatic cholangiography with the Chiba needle. Experience in 100 cases]

One-hundred cases submitted to percutaneous transhepatic cholangiography (PTC) with Chiba's needle were studied. Success rate was 93%, with 100% success in patients with dilated ducts and 78.8% in those with normal ducts. One false-positive result was noticed due to air injection into bile duct in the beginning of the procedure. Complications were seen in 8 cases, without fatalities ascribed to the PTC itself, nor emergency laparotomy was necessary in these cases.
