1Endoscopic submucosal dissection in dogs in a World Gastroenterology Organisation training center显示文摘AIM: To evaluate if canine models are appropriate for teaching endoscopy fellows the techniques of endoscopic submucosal dissection (ESD). METHODS: ESD was performed in 10 canine models under general anesthesia, on artificial lesions of the esophagus or stomach marked with coagulation points. After ESD, each canine model was euthanized and surgical resection of the esophagus or stomach was carried out according to 'The Principles of Humane Experimental Technique, Russel and Burch'. The ESD specimens were fixed with needles on cork submerged in a formol solution with the esophagus or stomach, and delivered to the pathology department to be analyzed. RESULTS: ESD was completed without complications using the Hook-knife in five esophageal areas, with a procedural duration of 124 ± 19 min, a length of 27.4 ± 2.6 mm and a width of 21 ± 2.4 mm. ESD was also completed without complications using the IT-knife2 in five gastric areas, with a procedural duration of 92.6 ± 19 min, a length of 32 ± 2.5 mm and a width of 18 ± 3.7 mm. CONCLUSION: ESD is feasible in the normal esopha- gus and stomach of canine models, which are appropriate for teaching this technique.Miguel A Tanimoto Gonzalo Torres-Villalobos Rikiya Fujita Patricio Santillan-Doherty Jorge Albores-Saavedra German Gutierrez Luis A Martin-del-Campo Carlos Bravo-Reyna Octavio Villanueva Jose J Villalobos Misael Uribe Miguel A Valdovinos 2010World Journal of Gastroenterology2010,16,14:7

3Conversion from calcineurin inhibitors to mTOR inhibitors stabilizes diabetic and hypertensive nephropathy after liver transplant显示文摘AIM: To investigate if conversion to the mammalian target of rapamycin inhibitors(mTORi) improves renal function in diabetic and/or hypertensive liver transplant patients immunosuppressed with tacrolimus or cyclosporine.METHODS: The study included 86 liver graft recipients immunosuppressed with mTORi treatment after orthotopic liver transplantation(OLT), including all liver recipients with worsening renal function before conversion to mTORi(n = 55 patients) and recipients with normal renal function who converted to m TORi for other reasons(n = 31 patients). We identified patients with diabetes mellitus(n = 28), arterial hypertension(n = 27), proteinuria(n = 27) and all three factors(n = 8)(some patients have hypertension and diabetes and no proteinuria). The primary endpoint was evolution in renal function defined as the development in plasma creatinine as a function of diabetes mellitus(DM), hypertension(HT) or proteinuria. We required elevated serum creatinine for at least two weeks to define renal dysfunction.RESULTS: Only patients that converted because of renal failure with plasma creatinine levels > 1.5 mg/dL showed an improvement of renal function(2.14 to 1.77 mg/dL)(P = 0.02). Patients with DM showed no improvement of serum creatinine levels(1.31 mg/dL to 1.37 mg/dL) compared with non DM patients(1.31 mg/dL to 1.15 mg/dL)(P = 0.01), HT patients(1.48 mg/dL to 1.5 mg/dL) with non HT patients(1.21mg/d L to 1.08 mg/dL) and patients with proteinuria(1.44 mg/dL to 1.41 mg/dL) and no proteinuria(1.31 mg/dL to 1.11 mg/dL). CONCLUSION: In OLT recipients with diabetes or hypertensive nephropathy, conversion to m TORi does not improve renal function but stabilizes plasma levels of creatinine. Proteinuria is not a contraindication to conversion to m TORi; it also stabilizes renal function. Conversion to m TORi should only be avoided in patients with diabetes, hypertension and proteinuria.José M álamo Claudia Olivares Lydia Barrera Luis M Marín Gonzalo Suarez Carmen Bernal Juan Serrano Jordi Muntané Francisco J Padillo Miguel A Gómez 2015World Journal of Transplantation2015,5,1:6
4Diagnostic value of drain amylase for detecting intrathoracic leakage after esophagectomy显示文摘AIM:To investigate the value of elevated drain amylase concentrations for detecting anastomotic leakage(AL) after minimally invasive Ivor-Lewis esophagectomy(MIILE).METHODS:This was a retrospective analysis of prospectively collected data in two hospitals in the Netherlands. Consecutive patients undergoing MI-ILE were included. A Jackson-Pratt drain next to the dorsal side of the anastomosis and bilateral chest drains were placed at the end of the thoracoscopic procedure. Amylase levels in drain fluid were determined in all patients during at least the first four postoperative days. Contrast computed tomography scans and/or endoscopic imaging were performed in cases of a clinically suspected AL. Anastomotic leakage was defined as any sign of leakage of the esophago-gastric anastomosis on endoscopy,re-operation,radiographic investigations,post mortal examination or when gastro-intestinal contents were found in drain fluid. Receiver operator characteristic curves were used to determine the cut-off values. Sensitivity,specificity,positive predictive value,negative predictive value,risk ratio and overall test accuracy were calculated for elevated drain amylase concentrations.RESULTS:A t o t a l o f 8 9 p a t ie n t s w e re in c lu d e d between March 2013 and August 2014. No differences in group characteristics were observed between patients with and without AL,except for age. Patients with AL were older than were patients without AL(P = 0.01). One patient(1.1%) without AL died within 30 d after surgery due to pneumonia and acute respiratory distress syndrome. Anastomotic leakage that required any intervention occurred in 15 patients(16.9%). Patients with proven anastomotic leakage had higher drain amylase levels than patients without anastomotic leakage [median 384 IU/L(IQR 34-6263) vs median 37 IU/L(IQR 26-66),P = 0.003]. Optimal cut-off values on postoperative days 1,2,and 3 were 350 IU/L,200 IU/L and 160 IU/L,respectively. An elevated amylase level was found in 9 of the 15 patients with AL. Five of these 9 patients had early elevations of their amylase levels,with a median of 2 d(IQR 2-5) before signs and symptoms occurred.CONCLUSION:Measurement of drain amylase levels is an inexpensive and easy tool that may be used to screen for anastomotic leakage soon after MI-ILE. However,clinical validation of this marker is necessary.Gijs HK Berkelmans Ewout A Kouwenhoven Boudewijn JJ Smeets Teus J Weijs Luis C Silva Corten Marc J van Det Grard AP Nieuwenhuijzen Misha DP Luyer 2015World Journal of Gastroenterology2015,21,30:3

6Hepatocellular carcinoma xenograft supports HCV replication:A mouse model for evaluating antivirals显示文摘AIM: To develop a hepatocellular carcinoma (HCC) xenograft model for studying hepatitis C virus (HCV) replication in a mice, and antiviral treatment.METHODS: We developed a stable S3-green fluorescence protein (GFP) cell line that replicated the GFP-tagged HCV sub-genomic RNA derived from a highly efficient JFH1 virus. S3-GFP replicon cell line was injected subcutaneously into γ-irradiated SCID mice. We showed that the S3-GFP replicon cell line formed human HCC xenografts in SCID mice. Cells were isolated from subcutaneous tumors and then serially passaged multiple times in SCID mice by culturing in growth medium supplemented with G-418. The mouse-adapted S3-GFP replicon cells were implanted subcutaneously and also into the liver of SCID mice via intrasplenic infusion to study the replication of HCV in the HCC xenografts. The tumor model was validated for antiviral testing after intraperitoneal injection of interferon-α (IFN-α). RESULTS: A highly tumorigenic S3-GFP replicon cell line was developed that formed subcutaneous tumors within 2 wk and diffuse liver metastasis within 4 wk in SCID mice. Replication of HCV in the subcutaneous and liver tumors was confirmed by cell colony assay, detection of the viral RNA by ribonuclease protection assay and real-time quantitative reverse transcription polymerase chain reaction. High-level replication of HCV sub-genomic RNA in the tumor could be visualized by GFP expression using fluorescence microscopy. IFN-α cleared HCV RNA replication in the subcutaneous tumors within 2 wk and 4 wk in the liver tumor model. CONCLUSION: A non-infectious mouse model allows us to study replication of HCV in subcutaneous and metastatic liver tumors. Clearance of HCV by IFN-α supports use of this model to test other anti-HCV drugs.Sidhartha Hazari Henry J Hefler Partha K Chandra Bret Poat Feyza Gunduz Tara Ooms Tong Wu Luis A Balart Srikanta Dash 2011World Journal of Gastroenterology2011,17,3:2
