Background and Aim Periampullary diverticula ( PAD ) are not uncommon findings during endoscopic retrograde cholangiopancreatography, but its clinical significance had not been established. To investigate the clinical characteristics associated with PAD and their relationships with the type and size of PAD in patients with common bile duct ( CBD ) stones was aimed. Methods Three hundred seventy patients undergoing endoscopic retrograde cholangiopancreatography between M arch 2010 and J uly 2012 were consecutively enrolled, and their demographics, laboratory data, and CBD stone‐related characteristics according to PAD type and PAD size were analyzed. Results Mean age, mean size of CBD stones, prevalence of systemic inflammatory response syndrome, and serum C ‐reactive protein level differed in patients with CBD stones according to the presence or absence of PAD . The presence of PAD and positive blood culture were correlated with systemic inflammatory response syndrome ( P = 0.033 and P < 0.001, respectively). The recurrence of CBD stones was more frequent, and the diameter of CBD was larger in patients with PAD type I than in those with PAD type III . Mean age and CBD diameter were lower in patients with PAD size < 15 mm than those with PAD size ≥ 15 mm. Multivariate analyses indicated that CBD diameter was related to PAD size ( P = 0.002) and the recurrence of CBD stones was related to PAD type ( P = 0.001). Conclusions PAD are associated with larger CBD stones and severe cholangitis with CBD stones. CBD diameter is related to PAD size, and the recurrence of CBD stones is related to PAD type.
