Summary
Percutaneous transhepatic transluminal forceps biopsy is a safe and feasible method for diagnosing bile duct diseases, achieving a 71% sensitivity rate. This minimally invasive technique aids in histopathologic diagnosis of various biliary tract tumors and inflammation.
Area of Science:
- Gastroenterology
- Interventional Radiology
- Surgical Pathology
Background:
- Bile duct diseases require accurate diagnosis for effective management.
- Percutaneous transluminal forceps biopsy offers a minimally invasive approach.
Purpose of the Study:
- To assess the technical feasibility and diagnostic sensitivity of percutaneous transluminal forceps biopsy for bile duct diseases.
- To evaluate the safety and ease of performance of this biopsy technique.
Main Methods:
- Seventeen fluoroscopic-guided transluminal forceps biopsies were performed in 16 patients with obstructive jaundice.
- The procedure utilized an existing percutaneous transhepatic tract, obtaining multiple specimens via a 9-French sheath.
- Specimens were fixed in formalin for histopathologic analysis.
Main Results:
- Adequate samples for diagnosis were obtained in 12 of 17 procedures, yielding a sensitivity of 71%.
- Diagnoses included pancreatic head carcinoma, cholangiocarcinoma, hepatoma, common bile duct tumors, and chronic inflammation.
- Minor complications included pain (3 patients) and transient hemobilia (2 patients).
Conclusions:
- Percutaneous transhepatic transluminal forceps biopsy is a safe and easily performed technique.
- The method is viable through an established transhepatic biliary tract.
- A diagnostic sensitivity of 71% was achieved for bile duct diseases.
