[Percutaneous biliary and gallbladder interventions].

Area of Science:

• Interventional Radiology
• Hepatobiliary Medicine
• Gastroenterology

Background:

• Percutaneous transhepatic interventions are vital for diagnosing and treating biliary tract diseases.
• These procedures are employed when endoscopic approaches are not feasible or have been exhausted.

Purpose of the Study:

• To review the current knowledge and scope of percutaneous biliary and gallbladder interventions.
• To provide an overview of technical approaches for fundamental interventional procedures.

Main Methods:

• Technical success rates up to 99% were reported.
• Complication rates were observed to be up to a maximum of 26%.

Main Results:

• Indications included opacification of the biliary tree and treatment of pathologies like drainage and stenting.
• Percutaneous transhepatic biliary drainage is a key procedure discussed.

Conclusions:

• Percutaneous transhepatic biliary and gallbladder interventions demonstrate safety and efficacy.
• These interventions are effective for benign and malignant stenosis, postoperative complications, and high-risk patients with cholecystitis.
