简要总结
Primary sclerosing cholangitis (PSC) is a chronic inflammatory disease of the biliary tract of unknown origin. Around 50% of patients develop during their disease course narrowing of the main bile duct with corresponding increase in symptoms such as itching, jaundice and abdominal pain. These narrowings can be treated by balloon dilatation or temporary insertion of a plastic endoprosthesis. However, it is not known which of these two therapeutic modalities is best. This study aims to compare both techniques in order to determine which is best in terms of postponing recurrence of the narrowing, safety and costs.
详细描述
Rationale:
Primary sclerosing cholangitis is a chronic progressive fibro-obliterative disease of the biliary tree leading to biliary cirrhosis. During its course, dominant strictures occur in approximately 50% of patients. These can be accompanied by lead worsening of symptoms and jaundice and are an indication for endoscopic treatment. The best form of treatment, either balloon dilatation or short-term stent placement, has never been formally investigated.
Objective:
Primary:
To compare the efficacy of single session balloon dilatation versus short-term stent placement in non-advanced PSC patients with regard to re-intervention free recurrence rate at two years.
