A randomised controlled trial of endoscopic sphincterotomy in acute cholangitis without common bile duct stones

Background: Biliary decompression with endoscopic sphincterotomy (EPT) is beneficial in patients with biliary obstruction due to common bile duct (CBD) stones. However, it is not known whether EPT with decompression of the bile duct is beneficial in patients with acute cholangitis and gall bladder stones but without evidence of CBD stones. Aim: A randomised controlled study to assess the effect of EPT on the outcome of patients suffering from acute cholangitis with gall bladder stones but with no CBD stones on initial endoscopic retrograde cholangiopancreatography. Patients: A total of 111 patients were recruited into the study. Methods and results: Fifty patients were randomised to receive EPT while 61 patients received no endoscopic intervention. There was a significant difference in the duration of fever in the EPT and non-EPT groups (mean (SD): 3.2 (2.2) days v 4.3 (2. 1) days; p<0.001). Duration of hospital stay was also shorter in the EPT group than in the non-EPT group (mean (SD): 8.1 (3.0) v 9.1 (3.2) days; p=0.04). Patients were followed up for a mean (SD) of 42.4 (11.1) months. Twenty three patients (20.3%) developed recurrent acute cholangitis (RAC): 14 patients (12.6%) in the EPT group and nine patients (8.1%) in the non-EPT group (p=0.09). Conclusion: EPT in patients with acute cholangitis without CBD stones decreased the duration of acute cholangitis and reduced hospital stay but it did not decrease the incidence of RAC.
