Percutaneous transhepatic cholangiography with the Chiba needle in patients with biliary calculi.
In a prospective study, 276 consecutive patients were evaluated using percutaneous transhepatic cholangiography (PTC) with a Chiba needle prior to surgery for cholestasis. Biliary calculi were diagnosed in 109 patients. The success rate was 92.4% overall, 93.6% among patients with biliary calculi, 83.3% in those with cholelithiasis, 97.3% in those with choledocholithiasis, and 100.0% in those with intrahepatic stones. The overall morbidity rate was 4.6%, including hemoperitoneum in 1.8% and bile leakage in 2.8%. There were no deaths. This technique offers a more definitive diagnosis than noninvasive procedures, especially with small calculi, but is also more traumatic. PTC may play an important role when noninvasive methods are inconclusive or in difficult cases, particularly following surgery on the common bile duct.
