Percutaneous transhepatic cholangiography using the "Chiba" needle--80 cases

Area of Science:

• Medical Imaging
• Gastroenterology
• Interventional Radiology

Background:

• Cholestatic jaundice presents diagnostic challenges.
• Accurate visualization of the biliary system is crucial for effective treatment planning.
• Percutaneous transhepatic cholangiography (PTC) offers a minimally invasive approach.

Purpose of the Study:

• To evaluate the efficacy of the Chiba needle for percutaneous transhepatic cholangiography (PTC) in patients with cholestatic jaundice.
• To determine the success rates of PTC based on bile duct dilation and obstruction.
• To assess the safety and utility of PTC in managing biliary obstruction.

Main Methods:

• The Chiba needle was used for percutaneous transhepatic cholangiography (PTC).
• Radiographic visualization of bile ducts was performed in 80 patients with cholestatic jaundice.
• Success rates were analyzed in relation to bile duct dilation and underlying causes of obstruction.

Main Results:

• Overall visualization success rate was 80% in 80 patients.
• Success rate was higher (94.4%) in patients with dilated bile ducts due to extrahepatic obstruction compared to those with undilated ducts (50%).
• Four patients developed ascending cholangitis with septicaemia post-procedure; early surgery is advised.

Conclusions:

• Percutaneous cholangiography with the Chiba needle is a valuable and convenient method for opacifying the biliary system in severe bile duct obstruction.
• The technique demonstrates high success rates, particularly in cases of dilated ducts.
• Careful patient selection and prompt surgical intervention are recommended to mitigate risks such as cholangitis.
