| 1 | Effect of precut sphincterotomy on post-endoscopic retrograde cholangiopancreatography pancreatitis:A systematic review and meta-analysis显示文摘AIM:To conduct a systemic review and meta-analysis to investigate the role of early precut technique.Multiple randomized controlled trails(RCTs)have reported conflicting results of the early precut sphincterotomy.METHODS:MEDLINE/PubMed,EMBASE,Cochrane Central Register of Controlled Trials and Database of Systematic Reviews,and recent abstracts from major conference proceedings were searched(June 2013).Randomized and non-randomized studies comparing early precut technique with prolonged standard methods were included.Pooled estimates of post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP),cannulation and adverse events were analyzed by using odds ratio(OR).Random and fixed effects models were used as appropriate.Publication bias was assessed by funnel plots.Heterogeneity among studies was assessed by calculating I2 measure of inconsistency.RESULTS:Seven randomized and seven non-randomized trials met inclusion criteria.Meta-analysis of RCTs showed a decrease trend for PEP with early precut sphincterotomy but was not statistically significant(OR=0.58;95%CI:0.32-1.05;P=0.07).No heterogeneity was noted among the studies with I2 of 0%.CONCLUSION:Early precut technique for common bile duct cannulation decreases the trend of post-ERCP pancreatitis. | Abhishek Choudhary Jessica Winn Sameer Siddique Murtaza Arif Zainab Arif Ghassan M Hammoud Srinivas R Puli Jamal A Ibdah Matthew L Bechtold | 2014 | World Journal of Gastroenterology2014，20，14： | 13 |
| 2 | Imaging of liver cancer显示文摘Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality. | Ben Ariff Claire R Lloyd Sameer Khan Mohamed Shariff Andrew V Thillainayagam Devinder S Bansi Shahid A Khan Simon D Taylor-Robinson Adrian KP Lim | 2009 | World Journal of Gastroenterology2009，15，11： | 4 |
| 3 | Haemoxygenase modulates cytokine induced neutrophil chemoattractant in hepatic ischemia reperfusion injury显示文摘AIM To investigate the hepatic microcirculatory changes due to Haemoxygenase(HO),effect of HO inhibition on remote ischemic preconditioning(RIPC) and modulation of CINC.METHODS Eight groups of animals were studied- Sham,ischemia reperfusion injury(IRI) the animals were subjected to 45 min of hepatic ischemia followed by three hours of reperfusion,RIPC(remote ischemic preconditioning) + IRI group,remote ischemic preconditioning in sham(RIPC + Sham),PDTC + IR(Pyridodithiocarbamate,HO donor),Zn PP + RIPC + IRI(Zinc protoporphyrin prior to preconditioning),IR-24(45 min of ischemia followed by 24 h of reperfusion),RIPC+IR-24(preconditioning prior to. After 3 and 24 h of reperfusion the animals were killed by exsanguination and samples were taken. RESULTS Velocity of flow(160.83 ± 12.24 μm/s),sinusoidal flow(8.42 ± 1.19) and sinusoidal perfusion index(42.12 ± 7.28) in hepatic IR were lower(P < 0.05) in comparison to RIPC and PDTC(HO inducer). RIPC increased velocity of flow(328.04 ± 19.13 μm/s),sinusoidal flow(17.75 ± 2.59) and the sinusoidal perfusion index(67.28 ± 1.82)(P < 0.05). PDTC(HO induction) reproduced the effects of RIPC in hepatic IR. PDTC restored RBC velocity(300.88 ± 22.109 μm/s),sinusoidal flow(17.66 ± 3.71) and sinusoidal perfusion(82.33 ± 3.5) to near sham levels. Zn PP(HO inhibition) reduced velocity of flow of RBC in the RIPC group(170.74 ± 13.43 μm/s and sinusoidal flow in the RIPC group(9.46 ± 1.34). Zn PP in RIPC(60.29 ± 1.82) showed a fall in perfusion only at 180 min of reperfusion. Neutrophil adhesion in IR injury is seen in both postsinusoidal venules(769.05 ± 87.48) and sinusoids(97.4 ± 7.49). Neutrophil adhesion in RIPC + IR injury is reduced in both postsinusoidal venules(219.66 ± 93.79) and sinusoids(25.69 ± 9.08)(P < 0.05). PDTC reduced neutrophil adhesion in both postsinusoidal venules(89.58 ± 58.32) and sinusoids(17.98 ± 11.01)(P < 0.05) reproducing the effects of RIPC. Zn PP(HO inhibition) increased venular(589.04 ± 144.36) and sinusoidal neutrophil adhesion in preconditioned animals(121.39 ± 30.65)(P < 0.05). IR after 24 h of reperfusion increased venular and sinusoidal neutrophil adhesion in comparison to the early phase and was significantly reduced by RIPC. Hepatocellular cell death in IRI(80.83 ± 13.03),RIPC + IR(17.35 ± 2.47),and PTDC+IR(11.66 ± 1.17) Zn PP + RIPC + IR(41.33 ± 3.07) reduced hepatocellular death. Zn PP significantly increased hepatocellular death(P < 0.05 PTDC/RIPC vs Zn PP and IR). The CINC cytokine levels in sham(101.32 ± 6.42). RIPC + sham(412.18 ± 65.24) as compared to sham(P < 0.05). Hepatic IR(644.08 ± 181.24)(P < 0.05). RIPC CINC-1 levels in the early phase(401.62 ± 78.56). And PDTC(HO inducer) CINC-1 levels in hepatic IR(413.36 ± 63.06) were significantly lower. HO inhibition in preconditioned animals with Zinc protoporphyrin increased serum CINC levels(521.81 ± 74.9)(P < 0.05). The serum CINC levels were high in the late phase of hepatic IR(15306 ± 1222.04). RIPC reduced CINC levels in the late phase of IR(467.46 ± 26.06),P < 0.05.CONCLUSION RIPC protects hepatic microcirculation by induction of HO and modulation of CINC in hepatic IR. | Niteen Tapuria Sameer Junnarkar Mahmoud Abu-amara Barry Fuller Alexander M Seifalian Brian R Davidson | 2016 | World Journal of Gastroenterology2016，22，33： | 3 |
