Effect of scheduled endoscopic dilatation of dominant strictures on outcome in patients with primary sclerosing cholangitis
Objective Scheduled endoscopic dilatation of dominant strictures (DS) in primary sclerosing cholangitis (PSC) might improve outcome relative to endoscopic treatment on demand, but evidence is limited. Since randomisation is difficult in clinical practice, we present a large retrospective study compa...

| Summary: | Objective Scheduled endoscopic dilatation of dominant strictures (DS) in primary sclerosing cholangitis (PSC) might improve outcome relative to endoscopic treatment on demand, but evidence is limited. Since randomisation is difficult in clinical practice, we present a large retrospective study comparing scheduled versus on-demand endoscopic retrograde cholangiopancreatography (ERCP) based on patient preferences. - Design Between 1987 and 2017, all new patients with PSC had been offered scheduled ERCP with dilatation of a DS if diagnosed; the latter was repeated at defined intervals until morphological resolution, independent of clinical symptoms (treatment group). Patients who refused participation were clinically evaluated annually and received endoscopic treatment only on demand (control group). The primary clinical endpoint was transplantation-free survival. Secondary outcomes were overall survival, bacterial cholangitis episodes, hepatic decompensation of liver cirrhosis and endoscopy-related adverse events. - Results The final study included 286 patients, 133 (46.5%) receiving scheduled ERCP and 153 (53.5%) receiving on-demand ERCP. After a mean follow-up of 9.9 years, the rate of transplantation-free survival was higher in patients receiving scheduled ERCP (51% vs 29.3%; p<0.001), as was transplantation-free survival time (median: 17.9 vs 15.2 years; log-rank: p=0.008). However, the benefit of scheduled ERCP was significant only in patients with the initial (17.1%) or later (45.5%) diagnosis of a DS (17.8 vs 11.1 years; log-rank: p<0.001). IBD (p=0.03), DS (p=0.006), higher Mayo Risk Score (p=0.02) and non-adherence to scheduled endoscopy (p=0.005) were independently associated with transplantation-free survival. - Conclusion In our large retrospective study, regular ERCP with endoscopic balloon dilatation significantly benefits patients with PSC with DS, diagnosed both at initial presentation and during surveillance, even if asymptomatic. Further studies have to find out how to best identify stricture patients non-invasively. |
