Abstract:
BACKGROUND/AIMS: Recent studies have reported the potentials of endoscopic papillary large balloon dilatation (EPLBD) with minor endoscopic sphincterotomy (EST) for the complete removal of common bile duct (CBD) stone in the high risk groups. However, there have been no reports about the recurrence of the CBD stone after EPLBD with minor EST. The aim of this study was to evlauate the recurrence of CBD stone after EPLBD with minor EST. METHODS: A total of 1,036 patients who underwent endoscopic treatment due to CBD stones at Pusan University Hospital were enrolled. The patients were classified into two groups: those who underwent EPLBD with minor EST (group 1) and those who underwent EST treatment (group 2). We investigated clinical factors and recurrence rate between two groups. RESULTS: The recurrence of CBD stone occurred in total of 74 patients (7%), and the recurrence rates of CBD stone were 21/321 (6.5%) in Group 1 and 53/715 (7.4%) in Group 2. There were no difference in the presence of diverticulum and the number and size of recurrent CBD stone between the two groups. In case of diverticulum existence, recurrence rates were 12/158 (7.6%) in Group 1 and 21/101 (20.8%) in Group 2. When compared to the case of no diverticulum existence (Group 1: 9/163 [5.5%], Group 2: 32/614 [5.2%]), the recurrence rate of CBD stone was significantly lower if treated after EPLBD with minor EST (p<0.01). CONCLUSIONS: CBD stone that recurs after going through EPLBD with minor EST can be successfully removed with an endoscopic treatment. The recurrence of CBD stone was especially lower in cases with periampullary diverticulum and treated with EPLBD with minor EST. Our results will be helpful in endoscopic retreatment and preventing the recurrence of CBD stone.
