Cholangiographic findings in deteriorating primary sclerosing cholangitis

Area of Science:

• Gastroenterology
• Hepatology
• Medical Imaging

Background:

• Primary sclerosing cholangitis (PSC) progression is unpredictable.
• Endoscopic retrograde cholangiopancreatography (ERCP) aids in diagnosing and treating PSC complications.
• Limited data exists on cholangiographic findings during PSC disease course.

Purpose of the Study:

• To describe the management and follow-up of six patients with deteriorating PSC using ERCP.
• To analyze cholangiographic changes and their correlation with clinical outcomes in PSC patients.

Main Methods:

• Retrospective analysis of 18 PSC patients diagnosed between 1981-1992.
• Detailed recording of clinical, biochemical, and cholangiographic findings during follow-up.
• Systematic ERCPs for monitoring disease progression and complications in a subset of patients.

Main Results:

• Six patients showed clinical and biochemical deterioration with worsening bile duct lesions on ERCP.
• Two patients developed cholangiocarcinoma; endoscopic therapy failed, and they died post-diagnosis.
• Four patients with dominant extrahepatic PSC benefited from endoscopic procedures, avoiding recurrent cholangitis.

Conclusions:

• ERCP is valuable for monitoring cholangiographic lesion progression in PSC.
• Endoscopic therapy can benefit PSC patients with extrahepatic duct involvement.
• Deteriorating PSC with dominant intrahepatic disease warrants consideration for liver transplantation.
