RESUMO
The authors employed this new technique of thin needle percutaneous cholangiography in 220 patients with the following results: 99.3% (146/147) success with previous biliary tract dilatation and 79.4% (53/73) success in patients with normal caliber bile ducts. The overall result of 92.7% (204/228) emphasizes that radiological opacification is the best way to study the icteric patient. Only 1.8% of patients with serious complications is less than in other instrumentation methods. By not requiring specialized equipment and being accessible in the majority of hospitals, study cost is reduced. In conclusion, this new technique of percutaneous cholangiography is preferable for accessibility, efficacy, cost and risk in the study of the icteric patient.
