| 1 | Current status of preoperative drainage for distal biliary obstruction显示文摘Preoperative biliary drainage(PBD) was developed to improve obstructive jaundice, which affects a number of organs and physiological mechanisms in patients waiting for surgery. However, its role in patients who will undergo pancreaticoduodenectomy for biliary obstruction remains controversial. This article aims to review the current status of the use of preoperative drainage for distal biliary obstruction. Relevant articles published from 1980 to 2015 were identified by searching MEDLINE and Pub Med using the keywords 'PBD', 'pancreaticoduodenectomy', and 'obstructive jaundice'. Additional papers were identified by a manual search of the references from key articles. Current studies have demonstrated that PBD should not be routinely performed because of the postoperative complications. PBD should only be considered in carefully selected patients, particularly in cases where surgery had to be delayed. PBD may be needed in patients with severe jaundice, concomitant cholangitis, or severe malnutrition. The optimal method of biliary drainage has yet to be confirmed. PBD should be performed by endoscopic routes rather than by percutaneous routes to avoid metastatic tumor seeding. Endoscopic stenting or nasobiliary drainage can be selected. Although more expensive, the use of metallic stents remains a viable option to achieve effective drainage without cholangitis and reintervention. | Harutoshi Sugiyama Toshio Tsuyuguchi Yuji Sakai Rintaro Mikata Shin Yasui Yuto Watanabe Dai Sakamoto Masato Nakamura Reina Sasaki Jun-ichi Senoo Yuko Kusakabe Masahiro Hayashi Osamu Yokosuka | 2015 | World Journal of Hepatology2015,7,18: | 11 |
| 2 | Endoscopic papillary large balloon dilation for removal of bile duct stones显示文摘AIM:To investigate the efficacy and outcomes of endoscopic papillary large balloon dilation(EPLBD)for bile duct stones in a multicenter prospective study.METHODS:Lithotomy by EPLBD was conducted in 124patients with bile duct stones≥13 mm in size or with three or more bile duct stones≥10 mm.After endoscopic sphincterotomy,the papilla was dilated using balloons 12-20 mm in diameter fitting the bile duct diameter.RESULTS:The success rate of first-time lithotomy was 86.3%(107/124)and the final lithotomy success rate was 100%(124/124).Lithotripsy was needed in10 of the 124(13.6%)patients.Adverse events due to the treatment procedure occurred in 6(4.8%)patients,all of which were mild.Performing large balloon dilation after endoscopic sphincterotomy in patients with large stones or multiple stones in the bile duct is considered to ensure the safety of treatment and to reduce the need for lithotripsy.CONCLUSION:It is suggested that treatment by EPLBD for large bile duct stones may be safe and useful. | Yuji Sakai Toshio Tsuyuguchi Yoshiaki Kawaguchi Nobuto Hirata So Nakaji Katsuya Kitamura Shigeru Mikami Tatsuya Fujimoto Masashi Ijima Eishin Kurihara Shuhei Oana Takayoshi Nishino Ryo Tamura Dai Sakamoto Masato Nakamura Takao Nishikawa Harutoshi Sugiyama Hitoshi Yoshida Tetsuya Mine Osamu Yokosuka | 2014 | World Journal of Gastroenterology2014,20,45: | 6 |
| 3 | Endoscopic papillary large balloon dilation for bile duct stones in elderly patients显示文摘AIM: To investigate whether endoscopic papillary large balloon dilation(EPLBD) can be safety and effectively performed in patients aged ≥ 80 years. METHODS: Lithotomy by EPLBD was conducted in 106 patients with bile duct stones ≥ 13 mm in size or with three or more bile duct stones ≥ 10 mm. The patients were divided into group A(< 80 years) and group B(≥ 80 years). Procedure success rate, number of endoscopic retrograde cholangiopancreatographies(ERCP), and incidence of complications were examined in both groups.RESULTS: Group B tended to include significantly more patients with peripapillary diverticulum, hypertension, hyperlipemia, cerebrovascular disease/dementia, respiratory disease/cardiac disease, and patients administered an anticoagulant or antiplatelet agent(P < 0.05). The success rate of the initial lithotomy was 88.7(94/106)%. The final lithotomy rate was 100(106/106)%. Complications due to treatment procedure occurred in 4.72(5/106)% of the patients. There was no significant difference in procedure success rate, number of ERCP, or incidence of complications between group A and group B.CONCLUSION: EPLBD can be safely performed in elderly patients, the same as in younger patients. | Yuji Sakai Toshio Tsuyuguchi Harutoshi Sugiyama Reina Sasaki Dai Sakamoto Masato Nakamura Yuuto Watanabe Takao Nishikawa Shin Yasui Rintaro Mikata Osamu Yokosuka | 2015 | World Journal of Clinical Cases2015,3,4: | 4 |

| 5 | New tapered metallic stent for unresectable malignant hilar bile duct obstruction显示文摘AIM: To examine the usefulness of a new tapered metallic stent(MS) in patients with unresectable malignant hilar bile duct obstruction.METHODS: This new tapered MS was placed in 11 patients with Bismuth Ⅱ or severer unresectable malignant hilar bile duct obstruction, as a prospective study. The subjects were six patients with bile duct carcinoma, three with gallbladder cancer, and two with metastatic bile duct obstruction. Stenosis morphology was Bismuth Ⅱ: 7, Ⅲa: 3, and Ⅳ: 1. UMIN Clinical Trial Registry(UMIN000004758).RESULTS: MS placement was 100%(11/11) successful. There were no procedural accidents. The mean patency period was 208.401 d, the median survival period was 142.000 d, and the mean survival period was 193.273 d. Occlusion rate was 36.4%(4/11); the causes of occlusion were ingrowth and overgrowth in 2 patients each, 18.2%, respectively. Patients with occlusion underwent endoscopic treatment one more time and all were treatable. CONCLUSION: The tapered MS proved useful in patients with unresectable malignant hilar bile duct obstruction because it provided a long patency period, enabled re-treatment by re-intervention, and no procedural accidents occurred. | Yuji Sakai Toshio Tsuyuguchi Takao Nishikawa Harutoshi Sugiyama Reina Sasaki Dai Sakamoto Yuto Watanabe Masato Nakamura Shin Yasui Rintaro Mikata Osamu Yokosuka | 2015 | World Journal of Clinical Cases2015,3,10: | 1 |

| 8 | Observatory science with eXTP显示文摘In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to Observatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in the mid 2020s. | Jean J.M.in 't Zand Enrico Bozzo JinLu Qu Xiang-Dong Li Lorenzo Amati Yang Chen Immacolata Donnarumma Victor Doroshenko Stephen A.Drake Margarita Hernanz Peter A.Jenke Thomas J.Maccarone Simin Mahmoodifar Domitilla de Martino Alessandra De Rosa Elena M.Rossi Antonia Rowlinson Gloria Sala Giulia Stratta Thomas M.Tauris Joern Wilms XueFeng Wu Ping Zhou Iván Agudo Diego Altamirano Jean-Luc Atteia Nils A.andersson M.Cristina Baglio David R.Ballantyne Altan Baykal Ehud Behar Tomaso Belloni Sudip Bhattacharyya Stefano Bianchi Anna Bilous Pere Blay Joao Braga Sφren Brandt Edward F.Brown Niccolo Bucciantini Luciano Burderi Edward M.Cackett Riccardo Campana Sergio Campana Piergiorgio Casella Yuri Cavecchi Frank Chambers Liang Chen Yu-Peng Chen Jér?me Chenevez Maria Chernyakova ChiChuan Jin Riccardo Ciolfi Elisa Costantini Andrew Cumming Antonino D'Aì Zi-Gao Dai Filippo D'Ammando Massimiliano De Pasquale Nathalie Degenaar Melania Del Santo Valerio D'Elia Tiziana Di Salvo Gerry Doyle Maurizio Falanga XiLong Fan Robert D.Ferdman Marco Feroci Federico Fraschetti Duncan K.Galloway Angelo F.Gambino Poshak Gandhi MingYu Ge Bruce Gendre Ramandeep Gill Diego G?tz Christian Gouiffès Paola Grandi Jonathan Granot Manuel Güdel Alexander Heger Craig O.Heinke Jeroen Homan Rosario Iaria Kazushi Iwasawa Luca Izzo Long Ji Peter G.Jonker Jordi José Jelle S.Kaastra Emrah Kalemci Oleg Kargaltsev Nobuyuki Kawai Laurens Keek Stefanie Komossa Ingo Kreykenbohm Lucien Kuiper Devaky Kunneriath Gang Li En-Wei Liang Manuel Linares Francesco Longo FangJun Lu Alexander A.Lutovinov Denys Malyshev Julien Malzac Antonios Manousakis Ian McHardy Missagh Mehdipour YunPeng Men Mariano Méndez Roberto P.Mignani Romana Mikusincova M.Coleman Miller Giovanni Miniutti Christian Motch Joonas Nättilä Emanuele Nardini Torsten Neubert Paul T.O'Brien Mauro Orlandini Julian P.Osborne Luigi Pacciani Stéphane Paltani Maurizio Paolillo Iossif E.Papadakis Biswajit Paul Alberto Pellizzoni Uria Peretz Miguel A.Pérez Torres Emanuele Perinati Chanda Prescod-Weinstein Pablo Reig Alessandro Riggio Jerome Rodriguez Pablo Rodríguez-Gil Patrizia Romano Agata Rózańska Takanori Sakamoto Tuomo Salmi Ruben Salvaterra andrea Sanna andrea Santangelo Tuomas Savolainen Stéphane Schanne Hendrik Schatz LiJing Shao andy Shearer Steven N.Shore Ben W.Stappers Tod E.Strohmayer Valery F.Suleimanov Jirí Svoboda F.-K.Thielemann Francesco Tombesi Diego F.Torres Eleonora Torresi Sara Turriziani andrea Vacchi Stefano Vercellone Jacco Vink Jian-Min Wang JunFeng Wang Anna L.Watts ShanShan Weng Nevin N.Weinberg Peter J.Wheatley Rudy Wijnands Tyrone E.Woods Stan E.Woosley ShaoLin Xiong YuPeng Xu Zhen Yan George Younes WenFei Yu Feng Yuan Luca Zampieri Silvia Zane andrzej A.Zdziarski Shuang-Nan Zhang Shu Zhang Shuo Zhang Xiao Zhang Michael Zingale | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,2: | 0 |
