| 1 | Three benefits of microcatheters for retrograde transvenous obliteration of gastric varices显示文摘AIM:To evaluate the usefulness of the microcatheter techniques in balloon-occluded retrograde transvenous obliteration (BRTO) of gastric varices.METHODS:Fifty-six patients with gastric varices underwent BRTOs using microcatheters.A balloon catheter was inserted into gastrorenal or gastrocaval shunts.A microcatheter was navigated close to the varices,and sclerosant was injected into the varices through the microcatheter during balloon occlusion.The next morning,thrombosis of the varices was evaluated by contrast enhanced computed tomography (CE-CT).In patients with incomplete thrombosis of the varices,a second BRTO was performed the following day.Patients were followed up with CE-CT and endoscopy.RESULTS:In all 56 patients,sclerosant was selectively injected through the microcatheter close to the varices.In 9 patients,microcoil embolization of collateral veinswas performed using a microcatheter.In 12 patients with incomplete thrombosis of the varices,additional injection of sclerosant was performed through the microcatheter that remained inserted overnight.Complete thrombosis of the varices was achieved in 51 of 56 patients,and the remaining 5 patients showed incomplete thrombosis of the varices.No recurrence of the varices was found in the successful 51 patients after a median follow up time of 10.5 mo.We experienced one case of liver necrosis,and the other complications were transient.CONCLUSION:The microcatheter techniques are very effective methods for achieving a higher success rate of BRTO procedures. | Tetsuo Sonomura Wataru Ono Morio Sato Shinya Sahara Kouhei Nakata Hiroki Sanda Nobuyuki Kawai Hiroki Minamiguchi Motoki Nakai Kazushi Kishi | 2012 | World Journal of Gastroenterology2012，18，12： | 5 |
| 2 | A case of very large intrahepatic bile duct adenoma followed for 7 years显示文摘A 70-year-old man was referred to our hospital due to abnormal liver function. A tumor of 92 mm × 61 mm was detected on ultrasound screening of the left liver lobe. Although the tumor was suspected to be intrahepatic bile duct carcinoma, he had chronic heart disease and was unable to undergo surgery. Therefore, he was followed without further testing. No increase in tumor serum markers or tumor size was observed for the subsequent 7 years. We continued to suspect intrahepatic bile duct carcinoma, and we decided to perform a tumor biopsy. Tumor biopsy findings indicated intrahepatic bile duct adenoma(BDA), which is a rare benign epithelial liver tumor typically ranging from 1 mm to20 mm. We herein report a case of very large BDA followed for 7 years. | Futa Koga Hiroto Tanaka Seigo Takamatsu Shinnichi Baba Hiroshi Takihara Akioko Hasegawa Eri Yanagihara Taro Inoue Toshihiro Nakano Chie Ueda Wataru Ono | 2012 | World Journal of Clinical Oncology2012，3，4： | 3 |
| 3 | Emergency balloon-occluded retrograde transvenous obliteration of ruptured gastric varices显示文摘AIM: To evaluate the effectiveness and safety of emergency balloon-occluded retrograde transvenous obliteration(BRTO) for ruptured gastric varices.METHODS: Emergency BRTO was performed in 17 patients with gastric varices and gastrorenal or gastrocaval shunts within 24 h of hematemesis and/or tarry stool.The gastric varices were confirmed by endoscopy,and the gastrorenal or gastrocaval shunts were identified by contrast-enhanced computed tomography(CE-CT).A 6-Fr balloon catheter(Cobra type) was inserted into the gastrorenal shunt via the right internal jugular vein,or into the gastrocaval shunt via the right femoral vein,depending on the varices drainage route.The sclerosant,5% ethanolamine oleate iopamidol,was injected into the gastric varices through the catheter during balloon occlusion.In patients with incom plete thrombosis of the varices after the first BRTO,a second BRTO was performed the following day.Patients were followed up by endoscopy and CE-CT at 1 d,1 wk,and 1,3 and 6 mo after the procedure,and every 6 mo thereafter.RESULTS: Complete thrombosis of the gastric varices was not achieved with the first BRTO in 7/17 patients because of large gastric varices.These patients underwent a second BRTO on the next day,and additional sclerosant was injected through the catheter.Complete thrombosis which led to disappearance of the varices was achieved in 16/17 patients,while the remaining patient had incomplete thrombosis of the varices.None of the patients experienced rebleeding or recurrence of the gastric varices after a median follow-up of 1130 d(range 8-2739 d).No major complications occurred after the procedure.However,esophageal varices worsened in 5/17 patients after a mean follow-up of 8.6 mo.CONCLUSION: Emergency BRTO is an effective and safe treatment for ruptured gastric varices. | Tetsuo Sonomura Wataru Ono Morio Sato Shinya Sahara Kouhei Nakata Hiroki Sanda Nobuyuki Kawai Hiroki Minamiguchi Motoki Nakai Kazushi Kishi | 2013 | World Journal of Gastroenterology2013，19，31： | 2 |
