Percutaneous-endoscopic biliary stent placement. A preliminary report.

Area of Science:

• Interventional Gastroenterology
• Hepatobiliary Medicine
• Endoscopic Therapeutics

Background:

• Percutaneous-transhepatic placement of large-bore biliary endoprostheses is associated with pain, large tracts, and high complication rates.
• Endoscopic stent placement requires specialized equipment and skills, and can be challenging with tight stenoses.

Purpose of the Study:

• To introduce and evaluate a simpler combined percutaneous-endoscopic biliary stent (PEBS) placement technique.
• To assess the efficacy and safety of the PEBS technique in patients with advanced malignant biliary obstruction.

Main Methods:

• A combined percutaneous-endoscopic approach was used for biliary stent placement in 11 patients.
• Large-bore stents (10 and 11.5 French) were utilized in all cases.

Main Results:

• The PEBS technique demonstrated a high stent placement rate.
• 10 out of 11 patients showed improved liver function tests, and 8 reported enhanced quality of life.
• Complications included three cases of sepsis (responsive to antibiotics), one clogged stent requiring replacement, and two stents needing endoscopic adjustment.

Conclusions:

• The combined percutaneous-endoscopic biliary stent (PEBS) technique is a simpler and effective method for placing large-bore stents in malignant biliary obstruction.
• This approach offers a high success rate and leads to improved liver function and quality of life in patients.
• While complications like sepsis can occur, they are manageable, making PEBS a viable alternative to traditional methods.
