作者： Min-Gui Han Eunae Cho Chang-hwan Park chung-hwan jun Seon-Young Park Division of Gastroenterology Department of Internal MedicineChonnam National University Hospital42Jaebong-roDong-KuGwangju 61482Korea

Background: Efficient ampullary intervention is essential for endoscopic retrograde cholangiopancreatography(ERCP) in patients with a prior Billroth II gastrectomy. We retrospectively evaluated the safety and effectiveness of ampullary intervention using fully covered self-expandable metal stents(FCSEMSs) for the management of common bile duct(CBD) stones in a subset of patients with a history of Billroth II gastrectomy. Methods: This retrospective analysis involved patients with a prior Billroth II gastrectomy who underwent ampullary intervention with FCSEMSs for the management of CBD stones. The factors associated with FCSEMSs placement, treatment success, and procedural complications were analyzed. Results: A group of 15 patients(10 males; median age, 78 years) underwent biliary metal stent placement for high degree of CBD angulation(6), small or flat papilla with unclear margin(5), current use of double antiplatelet agents or an anticoagulant(2), unwanted instrumentation of the cystic duct(1), and insecure position of the scope(1). Ampullary intervention with FCSEMSs was successful in all patients. After dilating the ampulla of Vater and building a durable conduit with FCSEMSs immediately, CBD stones were removed successfully from all patients in a single session. A mild post-ERCP pancreatitis occurred in one patient, who recovered without complications. Conclusion: Ampullary intervention with FCSEMSs is safe and effective for the management of CBD stones in a subset of patients with a history of Billroth II gastrectomy.

AIM:To investigate the risk factors and characteristics of hepatocellular carcinoma(HCC) in the patients with drug-resistant chronic hepatitis B(CHB).METHODS:A total of 432 patients with drug-resistant CHB were analyzed retrospectively from January 2004to December 2012. The patients were divided into two groups:the HCC group(n = 57) and the non-HCC group(n = 375). Two groups compared using logistic regression for various patients and viral characteristics in order to identify associated risk factors for ***,patient and tumor characteristics of HCC patients with na ve CHB(N group,n = 117) were compared to the HCC group(R group,n = 57) to identify any difference in HCC characteristics between ***:A significant difference was found for age,platelet count,alpha-fetoprotein(AFP),positivity of HBeAg,seroconversion rate of HBeAg,virologic response,the Child-Pugh score,presence of rtM204I,and the duration of antiviral treatment in non-HCC and HCC group. Cirrhosis,age(> 50 years),HBeAg(+),virologic non-responder status,and rtM204I mutants were independent risk factors for the development of HCC. The R group had lower serum C-reactive protein(CRP) and AFP levels,earlier stage tumors,and a shorter mean tumor surveillance period than the N group. However,the total follow-up duration was not significantly different between the two ***:13.2% of patients with drug-resistant CHB developed HCC. Age,cirrhosis,YIDD status,HBeAg status,and virologic response are associated with risk of HCC. Patients with drug-resistant CHB and these clinical factors may benefit from closer HCC surveillance.
