In primary sclerosing cholangitis, the development of a dominant biliary stricture can drive significant symptoms including pruritus and cholangitis. When these features are present, a structured intervention is indicated to relieve obstruction and address the infectious risk.

Clinical Scenario

This protocol addresses PSC patients in whom a dominant stricture is identified as the source of active symptoms — specifically pruritus and/or cholangitis. The treatment goals are relief of biliary obstruction, resolution of cholangitis, and sustained reduction in pruritus.

Management Approach (partial overview)

An endoscopic procedure targeting the dominant stricture, together with peri-procedural antibiotic coverage, forms the foundation of management. Whether additional measures are required depends on the degree of stricture severity. The complete protocol — including antibiotic regimen, procedural sequence, and criteria for further intervention — is available in the full evidence-based resource.

ERCP with balloon dilatation is recommended for PSC patients with dominant stricture and pruritus, and/or cholangitis, to relieve symptoms.
PSC patients undergoing ERCP should have antibiotic prophylaxis to prevent post-ERCP cholangitis.
Routine stenting after dilation of a dominant stricture is not required, whereas short-term stenting may be required in patients with severe stricture.
Preoperative antibiotics followed by a 3- to 5-day course post ERCP have been advised, using quinolones or cephalosporins, although no prospective studies have been performed to determine the best antibiotic choices.
In patients with deterioration and a dominant stricture perform ERCP with peri-procedure antibiotics and consider balloon dilation, with stent if needed.
