Cholangitis Clinical Trials

In patients with PSC, endoscopic therapy of strictures aims to improve cholestasis by relieving the biliary obstruction via endoscopic biliary dilatation with consideration of plastic stents in strictures refractory to dilatation due to the risk of pancreatitis and cholangitis . Short term stents have been shown to have similar recurrence-free rates compared to dilatation in a randomised control trial; however, this was terminated after interim analysis due to higher rates of serious adverse events in the stent group. The long term benefits are unclear; however, it may lead to improved survival compared to predicted survival. In this group of patients with limited treatment options, biodegradable stents may provide an attractive additional treatment modality in the management of high grade strictures.
