| 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 | Survival of geriatric patients after percutaneous endoscopic gastrostomy in Japan显示文摘AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient’s characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors. | Yutaka Suzuki Seryna Tamez Akihiko Murakami Akihiko Taira Akihiro Mizuhara Akira Horiuchi Chie Mihara Eiji Ako Hirohito Muramatsu Hitoshi Okano Hitoshi Suenaga Kazuaki Jomoto Junya Kobayashi Katsunari Takifuji Kazuhiro Akiyama Koh Tahara Koji Onishi Makoto Shimazaki Masami Matsumoto Masashi Ijima Masato Murakami Masato Nakahori Michiaki Kudo Michio Maruyama Mikako Takahashi Naohiro Washizawa Shigeru Onozawa Satoshi Goshi Satoyoshi Yamashita Shigeki Ono Shin Imazato Shinji Nishiwaki Shuichirou Kitahara Takao Endo Takao Iiri Takeshi Nagahama Takuto Hikichi Tatsuya Mikami Tetsuo Yamamoto Tetsushi Ogawa Tomoko Ogawa Tomoyuki Ohta Toshifumi Matsumoto Toshiroh Kura Tsutomu Kikuchi Tsuyoshi Iwase Tsuyotoshi Tsuji Yukio Nishiguchi Mitsuyoshi Urashima | 2010 | World Journal of Gastroenterology2010，16，40： | 4 |
| 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 |
| 4 | Sessile serrated adenoma detection rate is correlated with adenoma detection rate显示文摘AIM To investigated the association between adenoma detection rate(ADR) and sessile serrated ADR(SSADR) and significant predictors for sessile serrated adenomas(SSA) detection.METHODS This study is a retrospective, single-center analysis. Total colonoscopies performed by the gastroenterologists at the University of Tokyo Hospital between January and December 2014 were retrospectively identified. Polyps were classified as low-grade or high-grade adenoma, cancer, SSA, or SSA with cytological dysplasia, and the prevalence of each type of polyp was investigated. Predictors of adenoma and SSA detection were examined using logistic generalized estimating equation models. The association between ADR and SSADR for each gastroenterologist was investigated by calculating a correlation coefficient weighted by the number of each gastroenterologist's examination.RESULTS A total of 3691 colonoscopies performed by 35 gastroenterologists were assessed. Overall, 978 (26.5%) low-and 84 (2.2%) high-grade adenomas, 81 (2.2%) cancers, 66 (1.8%) SSAs, and 2 (0.1%) SSAs with cytological dysplasia were detected. Overall ADR was 29.5%(men 33.2%, women 23.8%) and overall SSADR was 1.8%(men 1.7%, women 2.1%). In addition, 672 low-grade adenomas (68.8% of all the detected lowgrade adenomas), 58 (69.9%) high-grade adenomas, 29 (34.5%) cancers, 52 (78.8%) SSAs, and 2 (100%) SSAs with cytological dysplasia were found in the proximal colon. Adenoma detection was the only significant predictor of SSA detection (adjusted OR: 2.53, 95%CI: 1.53-4.20; P < 0.001). The correlation coefficient between ADR and SSADR weighted by the number of each gastroenterologist's examinations was 0.606(P < 0.001).CONCLUSION Our results demonstrated that ADR is correlated to SSADR. In addition, patients with adenomas had a higher prevalence of SSAs than those without adenomas. | Daisuke Ohki Yosuke Tsuji Tomohiro Shinozaki Yoshiki Sakaguchi Chihiro Minatsuki Hiroto Kinoshita Keiko Niimi Satoshi Ono Yoku Hayakawa Shuntaro Yoshida Atsuo Yamada Shinya Kodashima Nobutake Yamamichi Yoshihiro Hirata Tetsuo Ushiku Mitsuhiro Fujishiro Masashi Fukayama Kazuhiko Koike | 2018 | World Journal of Gastrointestinal Oncology2018，10，3： | 2 |

| 11 | Orbit insertion strategy of Hayabusa2’s rover with large release uncertainty around the asteroid Ryugu显示文摘This paper describes the orbit design of the deployable payload Rover 2 of MINERVA-II,installed on the Hayabusa2 spacecraft.Because Rover 2 did not have surface exploration capabilities,the operation team decided to experiment with a new strategy for its deployment to the surface.The rover was ejected at a high altitude and made a semi-hard landing on the surface of the asteroid Ryugu after several orbits.Based on the orbital analysis around Ryugu,the expected collision speed was tolerable for the rover to function post-impact.Because the rover could not control its position,its motion was entirely governed by the initial conditions.Thus,the largest challenge was to insert the rover into a stable orbit(despite its large release uncertainty),and avoid its escape from Ryugu due to an environment strongly perturbed by solar radiation pressure and gravitational irregularities.This study investigates the solution space of the orbit around Ryugu and evaluates the orbit’s robustness by utilizing Monte Carlo simulations to determine the orbit insertion policy.Upon analyzing the flight data of the rover operation,we verified that the rover orbited Ryugu for more than one period and established the possibility of a novel method for estimating the gravity of an asteroid. | Yusuke Oki Kent Yoshikawa Hiroshi Takeuchi Shota Kikuchi Hitosi Ikeda Daniel JScheeres Jay WMcMahon Junichiro Kawaguchi Yuto Takei Yuya Mimasu Naoko Ogawa Go Ono Fuyuto Terui Manabu Yamada Toru Kouyama Shingo K ameda Kazuya Yoshida Kenji Nagaoka Tetsuo Yoshimitsu Takanao Saiki Yuichi Tsuda | 2020 | Astrodynamics2020，4，4： | 1 |
