58 ± 13.77 years. We observed PEP in 24 out of 169 patients (14%), 13 males (54.2%) and 11 females (45.8%). Mean duration of procedure was 45 ± 26.00 min. Mean values of bilirubin in the PEP patients was 193 ± 31.22 μmol/l.

We found significant positive correlation between level of total bilirubin, t 1.93 (df = 2.167) p < 0.05 and GGT t 2.35 (df 2.167) p < 0.02 with occurrence of PEP. There is no correlation between AP and incidence of PEP, t −0.106 (df 2.167) p < 0.05. Conclusion: Higher values of cholestatic markers observed in patients who developed PEP may be independent predictor for development of PEP. Key Word(s): 1. ERCP; 2.

useful for extracting large and multiple bile duct stones. Although there are many studies on the feasibility and short-term outcome, there are few reports about mid- to long-term outcome after ESLBD. The aim of our study is to evaluate the mid-term outcome of ESLBD. Methods: The records of 168 patients who underwent ESLBD between November 2006 and December 2011 were reviewed. The patients were observed until November 2012. Papillary dilation using large dilating balloon was performed following ES or prior ES. Results: The patients’ Trametinib mean age was 76.8 ± 9.8 years. Two cases received gastrectomy, 11 Billroth II gastrectomy and 15 with Roux-en Y reconstruction. Seventy (41.7%) patients had periampullary diverticulum. Prior ES had been performed on 33 (19.6%) patients. The mean follow-up period was 39.6 ± 13.7 months (range 11–69). Seven (4.2%) patients had stone recurrence (mean age 72.8 ± 7.8, Billroth MCE公司 II gastrectomy (1), gallstones (3), periampullary diverticulum (1), history of stone recurrence after prior ES (6)). There was no recurrence of stone in patients who first had ESLBD treatment with normal anatomy. Univariate analysis showed that prior ES and previous history of stone recurrence were predictive variables that could differentiate these

patients from the non-recurrence group. Multivariate analysis also showed that these were risk factors of stone recurrence (p < 0.001). Conclusion: Our mid-term outcome revealed that ESLBD itself has a low risk of recurrence of bile duct stones, although a favorable long-term outcome is mandatory. Key Word(s): 1.

The present study therefore was designed to evaluate the prevalence of gallstone in diabetic patients.
