| 1 | Helpfulness of the combination of acetic acid and FICE in the detection of Barrett's epithelium and Barrett's associated neoplasias显示文摘AIM:To investigate the mucosal morphology in Barrett's oesophagus by chromo and magnifying endoscopy.METHODS:A prospective pilot study at a tertiary medical centre was conducted to evaluate the use of acetic acid pulverisation combined with virtual chromoendoscopy using Fujinon intelligent chromoendoscopy(FICE) for semiological characterization of the mucosal morphology in Barrett's oesophagus and its neoplastic complications.Upper endoscopy using high definition whitelight,2% acid acetic pulverisation and FICE with high definition videoendoscopy were performed in 20 patients including 18 patients who presented with aspects of Barrett's oesophagus at endoscopy examination.Two patients used as controls had normal endoscopy and histological results.Prospectively,videos were watched blind from histological results by three trained FICE technique endoscopists.RESULTS:The videos of patients with high-grade dysplasia showed an irregular mucosal pattern in 14% using high definition white light endoscopy and in 100% using acid acetic-FICE combined.Videos did not identify irregular vascular patterns using high definition white light endoscopy,while acid acetic-FICE combined visualised one in 86% of cases.CONCLUSION:Combined acetic acid and FICE is a promising method for screening high-grade dysplasia and early cancer in Barrett's oesophagus. | Marine Camus Romain Coriat Sarah Leblanc Catherine Brezault Benoit Terris Elise Pommaret Marianne Gaudric Ariane Chryssostalis Frederic Prat Stanislas Chaussade | 2012 | World Journal of Gastroenterology2012，18，16： | 5 |
| 2 | Portal hypertensive duodenal polyp:A case report显示文摘Abnormalities of gastric mucosa in patients with portal hypertension are well documented. Manifestations of portal hypertension in small bowel and colon are less common. Colonic polypoid lesions microscopically consisting of a normal mucosa, with dilatation of submucosal vessels, have been described. We here report the first case of portal hypertensive duodenal polyp, responsible for gastro-intestinal bleeding. Endoscopic treatment turned out to be successful. | Jean-David Zeitoun Ariane Chryssostalis Benoit Terris Frederic Prat Marianne Gaudric Stanislas Chaussade | 2007 | World Journal of Gastroenterology2007，13，9： | 4 |

| 8 | Optimization of the generator settings for endobiliary radiofrequency ablation显示文摘AIM:To determine the optimal generator settings for endobiliary radiofrequency ablation. METHODS:Endobiliary radiofrequency ablation was performed in live swine on the ampulla of Vater,the common bile duct and in the hepatic parenchyma. Radiofrequency ablation time,'effect',and power were allowed to vary. The animals were sacrificed two hours after the procedure. Histopathological assessment of the depth of the thermal lesions was performed. RESULTS:Twenty-five radiofrequency bursts were applied in three swine. In the ampulla of Vater(n = 3),necrosis of the duodenal wall was observed starting with an effect set at 8,power output set at 10 W,and a 30 s shot duration,whereas superficial mucosal damage of up to 350 μm in depth was recorded for an effect set at 8,power output set at 6 W and a 30 s shot duration. In the common bile duct(n = 4),a 1070 μm,safe and efficient ablation was obtained for an effect set at 8,a power output of 8 W,and an ablation time of 30 s. Within the hepatic parenchyma(n = 18),the depth of tissue damage varied from 1620 μm(effect = 8,power = 10 W,ablation time = 15 s) to 4480 μm(effect = 8,power = 8 W,ablation time = 90 s). CONCLUSION:The duration of the catheter application appeared to be the most important parameter influencing the depth of the thermal injury during endobiliary radiofrequency ablation. In healthy swine,the currently recommended settings of the generator may induce severe,supratherapeutic tissue damage in the biliary tree,especially in the high-risk area of the ampulla of Vater. | Maximilien Barret Sarah Leblanc Ariane Vienne Alexandre Rouquette Frederic Beuvon Stanislas Chaussade Frederic Prat | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，16： | 0 |
