ABSTRACT
BACKGROUND/AIMS: To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of symptomatic pancreas divisum (PD) and to discuss whether ERCP procedures and outcomes in younger patients differ from those of adults. METHODS: Symptomatic patients with PD were included in the study and divided into underaged (age ≤17 years) and adult (age ≥18 years) group. The clinical information of each patient was reviewed, and then the patients were contacted by telephone or their medical records were reviewed to determine their long-term follow-up outcomes. RESULTS: A total of 141 procedures were performed in 82 patients (17 underaged and 65 adult patients). The ERCP indications included abdominal pain (39.02%), pancreatitis (12.20%), recurrent pancreatitis (36.59%), and other discomfort (12.20%). The endoscopic interventions included endoscopic pancreatic sphincterotomy in 44.68% of the patients, bouginage in 26.95%, pancreatic ductal stone extraction in 19.15%, endoscopic nasopancreatic drainage in 21.99%, and endoscopic retrograde pancreatic drainage in 56.74%. After a median follow-up of 41 months, the overall response rate was 62.32%. Between the underaged group and the adult group, significant differences were not observed in the ERCP procedures, complications and long-term follow-up results. CONCLUSIONS: ERCP is a safe and effective treatment for symptomatic PD. Based on the details, complications, and follow-up results, the ERCP procedure did not present differences between the underaged and adult groups.

Objective To investigate the effects of lovastatin,a widely used antilipemic agent,on cell proliferation,migration and apoptosis in human cholangiocarcinoma cell line QBC939 and explore its possible mechanism.Method After QBC939 cells were either incubated with lovastatin alone or without it as a control,the methylthiazolyl tetrazolium assay (MTT) assay was used to detect cell proliferation at the 24 h,48 h and 72 h mark; flow cytometry (FCM) measured apoptosis at 48 h;scratch assay was used to determine cell migration at 48h; RT-PCR and Western blot detected the expression of inflammatory cytokine interleukin-6 (IL-6),protein kinase (PKB/Akt),vascular endothelial growth factor (VEGF),matrix metalloproteinase-9 (MMP-9) mRNA and Akt protein at 48 h.Results Lovastatin significantly inhibited cell proliferation in a dose and time dependent manner (24 h,48 h and 72 h:F=173.05,159.66,577.87 respectively,all P＜0.01).After lovastatin treatment,apoptosis induction increased (t =15.28,P＜ 0.01 ) as did early apoptosis (t =13.24,P＜0.01),while the average migration velocity was reduced (24 h and 48 h:t=6.21,5.95,respectively,all P＜0.01).The Akt protein expression and mRNA expression of IL-6,Akt,VEGF,and MMP-9 were down-regulated after lovastatin treatment.Conclusions Lovastatin can inhibit cell proliferation,migration and promote apoptosis in human cholangiocarcinoma cell line QBC939.The mechanisms of suppression may be associated with down-regulation of IL-6,Akt,VEGF and MMP-9 expression.
ABSTRACT
Objective To study on the metal clip installation to avoid post-operative bleeding in pa- tients accepted papilla sphinctecotomy.Methods One hundred and eighty five patients who accepted ERCP +EST were divided into two groups:Group 1 was given routine regimen alone(N=95),group 2,given routine regimen and metal clip to prevent post-operative bleeding.Results The postoperative bleeding hap- pened in 3(3.2%)cases of Group 1 and none in Group 2,there is significant difference between these two groups(P＜0.05).The breeding cases in group 1 were controlled by metal clip under endoscopy successful- ly.Conclusion Preventive usage of metal clip was significantly decreased the incidence of post-operative bleeding in EST patients.
