| 1 | Novel image-enhanced endoscopy with i-scan technology显示文摘i-scan technology is the newly developed imageenhanced endoscopy technology from PENTAX,Japan.This consists of three types of algorithms:surface enhancement (SE),contrast enhancement (CE),and tone enhancement (TE).SE enhances light-dark contrast by obtaining luminance intensity data for each pixel and applying an algorithm that allows detailed observation of a mucosal surface structure.CE digitally adds blue color in relatively dark areas,by obtaining luminance intensity data for each pixel and applying an algorithm that allows detailed observation of subtle irregularities around the surface.Both enhancement functions work in real time without impairing the original color of the organ,therefore,SE and CE are suitable for screening endoscopy to detect gastrointestinal tumors at an early stage.TE dissects and analyzes the individual RGB components of a normal image.The algorithm then alters the color frequencies of each component and recombines the components to a single,new color image.This is designed to enhance minute mucosal structures and subtle changes in color.TE works in real time and consists of three modes such as TE-g for gastric tumors,TE-c for colonic tumors,and TE-e for esophageal tumors.TE is suitable mainly for detailed examination of the lesions that are detected in a screening endoscopy.i-scan technology leads us to easier detection,diagnosis and treatment of gastroi ntestinal diseases. | Shinya Kodashima Mitsuhiro Fujishiro | 2010 | World Journal of Gastroenterology2010，16，9： | 35 |
| 2 | Review of research on agricultural vehicle autonomous guidance显示文摘A brief review of research in agricultural vehicle guidance technologies is presented.The authors propose the conceptual framework of an agricultural vehicle autonomous guidance system,and then analyze its device characteristics.This paper introduces navigation sensors,computational methods,navigation planners and steering controllers.Sensors include global positioning systems(GPS),machine vision,dead-reckoning sensors,laser-based sensors,inertial sensors and geomagnetic direction sensors.Computational methods for sensor information are used to extract features and fuse data.Planners generate movement information to supply control algorithms.Actuators transform guidance information into changes in position and direction.A number of prototype guidance systems have been developed but have not yet proceeded to commercialization.GPS and machine vision fused together or one fused with another auxiliary technology is becoming the trend development for agricultural vehicle guidance systems.Application of new popular robotic technologies will augment the realization of agricultural vehicle automation in the future. | Ming Li Kenji Imou Katsuhiro Wakabayashi Shinya Yokoyama | 2009 | International Journal of Agricultural and Biological Engineering2009，2，3： | 21 |
| 3 | Efficacy of mosapride citrate with polyethylene glycol solution for colonoscopy preparation显示文摘AIM:To evaluate the efficacy and safety of adjunctive mosapride citrate for bowel preparation before colonoscopy. METHODS:We conducted a randomized,double-blind, placebo-controlled study with mosapride in addition to polyethylene glycol(PEG)-electrolyte solution.Of 250 patients undergoing colonoscopy,124 were randomized to receive 2 L PEG plus 15 mg of mosapride citrate (mosapride group),and 126 received 2 L PEG plus placebo(placebo group).Patients completed a questionnaire reporting the acceptability and tolerability of the bowel preparation process.The efficacy of bowel preparation was assessed by colonoscopists using a 5-point scale based on Aronchick's criteria.The primary end point was optimal bowel preparation rates(scores of excellent/good/fair vs poor/inadequate). RESULTS:A total of 249 patients were included in the analysis.In the mosapride group,optimal bowel preparation rates were significantly higher in the left colon compared with the placebo group(78.2%vs 65.6%,P<0.05),but not in the right colon(76.5%vs 66.4%,P=0.08).After excluding patients with severe constipation,there was a significant difference in bowel preparation in both the left and right colon(82.4%vs 66.7%,80.8%vs 67.5%,P<0.05,P<0.01).The incidence of adverse events was similar in both groups. Among the subgroup who had previous colonoscopy experience,a significantly higher number of patients in the mosapride group felt that the current preparation was easier compared with patients in the placebo group(34/72 patients vs 24/74 patients,P<0.05). CONCLUSION:Mosapride citrate may be an effective and safe adjunct to PEG-electrolyte solution that leads to improved quality of bowel preparation,especially in patients without severe constipation. | Masahiro Tajika Yasumasa Niwa Vikram Bhatia Hiroki Kawai Shinya Kondo Akira Sawaki Nobumasa Mizuno Kazuo Hara Susumu Hijioka Kazuya Matsumoto Yuji Kobayashi Akira Saeki Asana Akabane Koji Komori Kenji Yamao | 2012 | World Journal of Gastroenterology2012，18，20： | 21 |

| 5 | Bleeding after endoscopic submucosal dissection: Risk factors and preventive methods显示文摘Endoscopic submucosal dissection(ESD) has become widely accepted as a standard method of treatment for superficial gastrointestinal neoplasms because it enables en block resection even for large lesions or fibrotic lesions with minimal invasiveness, and decreases the local recurrence rate. Moreover, specimens resected in an en block fashion enable accurate histological assessment. Taking these factors into consideration, ESD seems to be more advantageous than conventional endoscopic mucosal resection(EMR), but the associated risks of perioperative adverse events are higher than in EMR. Bleeding after ESD is the most frequent among these adverse events. Although post-ESD bleeding can be controlled by endoscopic hemostasis in most cases, it may lead to serious conditions including hemorrhagic shock. Even with preventive methods including administration of acid secretion inhibitors and preventive hemostasis, post-ESD bleeding cannot be completely prevented. In addition high-risk cases for post-ESD bleeding, which include cases with the use of antithrombotic agents or which require large resection, are increasing. Although there have been many reports about associated risk factors and methods of preventing post-ESD bleeding, many issues remain unsolved. Therefore, in this review, we have overviewed risk factors and methods of preventing post-ESD bleeding from previous studies. Endoscopists should have sufficient knowledge of these risk factors and preventive methods when performing ESD. | Yosuke Kataoka Yosuke Tsuji Yoshiki Sakaguchi Chihiro Minatsuki Itsuko Asada-Hirayama Keiko Niimi Satoshi Ono Shinya Kodashima Nobutake Yamamichi Mitsuhiro Fujishiro Kazuhiko Koike | 2016 | World Journal of Gastroenterology2016，22，26： | 16 |
| 6 | Acute pancreatitis successfully diagnosed by diffusion-weighted imaging: A case report显示文摘Diffusion-weighted imaging (DWI) is an established diagnostic method of acute stroke. The latest advances in magnetic resonance imaging (MRI) technology have greatly expanded the utility of DWI in the examination of various organs. Recent studies have revealed the usefulness of DWI for imaging of the liver, kidney, ovary, and breast. We report a patient with acute pancreatitis detected by DWI and discussed the efficacy of DWI in diagnosing acute pancreatitis. A 50-year old man presented with a primary complaint of abdominal pain. We performed both DWI and computed tomography (CT) for this patient. The signal intensity in a series of DWI was measured and the apparent diffusion coefficient (ADC) values were calculated to differentiate inflammation from normal tissue. Two experienced radiologists evaluated the grade of acute pancreatitis by comparing the CT findings. Initially, the pancreas and multiple ascites around the pancreas produced a bright signal and ADC values were reduced on DWI. As the inflammation decreased, the bright signal faded to an iso-signal and the ADC values returned to their normal level. There was no difference in the abilities of DWI and CT images to detect acute pancreatitis. However, our case indicates that DWI can evaluate the manifestations of acute pancreatitis using no enhancement material andhas the potential to replace CT as a primary diagnostic strategy for acute pancreatitis. | Satoshi Shinya Takamitsu Sasaki Yoshifumi Nakagawa Zhang Guiquing Fumio Yamamoto Yuichi Yamashita | 2008 | World Journal of Gastroenterology2008，14，35： | 16 |
| 7 | Effect of Self-adhesive Resin Cement and Tribochemical Treatment on Bond Strength to Zirconia显示文摘Aim To evaluate the interactive effects of different self-adhesive resin cements and tribochemical treatment on bond strength to zirconia. Methodology The following self-adhesive resin cements for bonding two zirconia blocks were evaluated: Maxcem (MA), Smartcem (SM), Rely X Unicem Aplicap (UN), Breeze (BR), Biscem (BI), Set (SE), and Clearfil SA luting (CL). The specimens were grouped according to conditioning as follows: Group 1, polishing with 600 grit polishing paper; Group 2, silica coating with 110 μm Al2O3 particles which modified with silica; and, Group 3, tribochemical treatment - silica coating + silanization.Specimens were stored in distilled water at 37℃ for 24 hours before testing shear bond strength. Results Silica coating and tribochemical treatment significantly increased the bond strength of the MA, UN, BR, BI, SE and CL to zirconia compared to #600 polishing. For both #600 polished and silica coating treatments, MDP-containing self-adhesive resin cement CL had the highest bond strengths to zirconia. Conclusion Applying silica coating and tribochemical treatment improved the bond strength of self-adhesive resin cement to zirconia, especially for CL. | Akikazu Shinya Harunori Gomi Akiyoshi Shinya | 2010 | International Journal of Oral Science2010，2，1： | 14 |
| 8 | Rifaximin ameliorates hepatic encephalopathy and endotoxemia without affecting the gut microbiome diversity显示文摘AIM To determine the efficacy of rifaximin for hepatic encephalopathy(HE) with the linkage of gut microbiome in decompensated cirrhotic patients.METHODS Twenty patients(12 men and 8 women; median age, 66.8 years; range, 46-81 years) with decompensated cirrhosis(Child-pugh score > 7) underwent cognitive neuropsychological testing, endotoxin analysis, and fecal microbiome assessment at baseline and after 4 wk of treatment with rifaximin 400 mg thrice a day. HE was determined by serum ammonia level and number connection test(NCT)-A. Changes in whole blood endotoxin activity(EA) was analyzed by endotoxinactivity assay. Fecal microbiome was assessed by 16 S ribosome RNA(rR NA) gene sequencing.RESULTS Treatment with rifaximin for 4 wk improved hyperammonemia(from 90.6 ± 23.9 μg/d L to 73.1 ± 33.1 μg/dL; P < 0.05) and time required for NCT(from 68.2 ± 17.4 s to 54.9 ± 20.3 s; P < 0.05) in patients who had higher levels at baseline. Endotoxin activity was reduced(from 0.43 ± 0.03 to 0.32 ± 0.09; P < 0.05) in direct correlation with decrease in serum ammonia levels(r = 0.5886, P < 0.05). No statistically significant differences were observed in the diversity estimator(Shannon diversity index) and major components of the gut microbiome between the baseline and after treatment groups(3.948 ± 0.548 at baseline vs 3.980 ± 0.968 after treatment; P = 0.544), but the relative abundances of genus Veillonella and Streptococcus were lowered.CONCLUSION Rifaximin significantly improved cognition and reduced endotoxin activity without significantly affecting the composition of the gut microbiome in patients with decompensated cirrhosis. | Kosuke Kaji Hiroaki Takaya Soichiro Saikawa Masanori Furukawa Shinya Sato Hideto Kawaratani Mitsuteru Kitade Kei Moriya Tadashi Namisaki Takemi Akahane Akira Mitoro Hitoshi Yoshiji | 2017 | World Journal of Gastroenterology2017，23，47： | 14 |
| 9 | Diagnostic and therapeutic applications of water-immersion colonoscopy显示文摘Colonoscopy techniques combining or replacing air insufflation with water infusion are becoming increasinglypopular.They were originally designed to reduce colonic spasms,facilitate cecal intubation,and lower patient discomfort and the need for sedation.These maneuvers straighten the rectosigmoid colon and enable the colonoscope to be inserted deeply without causing looping of the colon.Water-immersion colonoscopy minimizes colonic distension and improves visibility by introducing a small amount of water.In addition,since pain during colonoscopy indicates risk of bowel perforation and sedation masks this important warning,this method has the potential to be the favored insertion technique because it promotes patient safety without sedation.Recently,this water-immersion method has not only been used for colonoscope insertion,but has also been applied to therapy for sigmoid volvulus,removal of lesions,lower gastrointestinal bleeding,and therapeutic diagnosis of abnormal bowel morphology and irritable bowel syndrome.Although a larger sample size and prospective head-to-head-designed studies will be needed,this review focuses on the usefulness of waterimmersion colonoscopy for diagnostic and therapeutic applications. | Shinya Sugimoto Takeshi Mizukami | 2015 | World Journal of Gastroenterology2015，21，21： | 13 |
| 10 | Treatment and prevention of gastrointestinal bleeding in patients receiving antiplatelet therapy显示文摘Antiplatelet therapy is the standard of care for the secondary prevention of acute coronary syndrome and ischemic stroke, especially after coronary intervention. However, this therapy is associated with bleeding complications such as gastrointestinal bleeding, which is one of the most common life-threatening complications. Early endoscopy is recommended for most patients with acute upper gastrointestinal bleeding. After successful endoscopic hemostasis, immediate resumption of antiplatelet therapy with proton-pump inhibitors(PPIs) is recommended to prevent further ischemic events. PPI prophylaxis during antiplatelet therapy reduces the risk of upper gastrointestinal bleeding. The potential negative metabolic interaction between PPIs and clopidogrel is still unclear. | Hiroshi Yasuda Yasumasa Matsuo Yoshinori Sato Sun-ichiro Ozawa Shinya Ishigooka Masaki Yamashita Hiroyuki Yamamoto Fumio Itoh | 2015 | World Journal of Critical Care Medicine2015，4，1： | 13 |
| 11 | 2018 update of expert consensus statement on antiplatelet therapy in East Asian patients with ACS or undergoing PCI显示文摘East Asians are the most populous race in the world and their health status is an important global issue.Compared with Caucasian populations, East Asian patients have a different benefit/risk ratio when using antithrombotic treatment. Despite this observation, treatment strategies in East Asian patients are mostly based on the American and European guidelines. Despite a lower platelet inhibitory response to clopidogrel, East Asian patients show a similar or even a lower rate of ischemic event occurrence and higher bleeding risk compared with Caucasian patients. For potent P2Y_(12) inhibitors(ticagrelor and prasugrel),East Asian patients have shown less favorable net clinical benefits compared with Caucasian patients,which may be related to differences in pharmacokinetic/pharmacodynamic profiles and therapeutic zone of antiplatelet effect. This updated consensus mainly focuses on state-of-the-art and current controversies in the East Asian population. In addition, when East Asian patients are administered potent P2Y_(12) receptor inhibitors, the strategies and ongoing trials to overcome the related hurdles are discussed. | Yong Huo Young-Hoon Jeong Yanjun Gong Daowen Wang Ben He Jiyan Chen Guosheng Fu Yundai Chen Jianping Li Yi Li Shinya Goto Udaya S.Tantry Paul A.Gurbel Jong-Hwa Ahn Hyo-Soo Kim Myung Ho Jeong Yaling Han Sidney C.Smith Jr. Junbo Ge | 2019 | Science Bulletin2019，64，3： | 12 |
| 12 | An updated review of gastric cancer in the next-generation sequencing era:Insights from bench to bedside and vice versa显示文摘Gastric cancer(GC)is one of the most common malignancies and remains the second leading cause of cancer-related death worldwide.There is an increasing understanding of the roles that genetic and epigenetic alterations play in GCs.Recent studies using nextgeneration sequencing(NGS)have revealed a number of potential cancer-driving genes in GC.Whole-exome sequencing of GC has identified recurrent somatic mutations in the chromatin remodeling gene ARID1A and alterations in the cell adhesion gene FAT4,a member of the cadherin gene family.Mutations in chromatin remodeling genes(ARID1A,MLL3 and MLL)have been found in 47%of GCs.Whole-genome sequencing and whole-transcriptome sequencing analyses have also discovered novel alterations in GC.Recent studies of cancer epigenetics have revealed widespread alterations in genes involved in the epigenetic machinery,such as DNA methylation,histone modifications,nucleosome positioning,noncoding RNAs and microRNAs.Recent advances in molecular research on GC have resulted in the introduction of new diagnostic and therapeutic strategies into clinical settings.The antihuman epidermal growth receptor 2(HER2)antibody trastuzumab has led to an era of personalized therapy in GC.In addition,ramucirumab,a monoclonal antibody targeting vascular endothelial growth factor receptor(VEGFR)-2,is the first biological treatment that showed survival benefits as a single-agent therapy in patients with advanced GC who progressed after firstline chemotherapy.Using NGS to systematically identify gene alterations in GC is a promising approach with remarkable potential for investigating the pathogenesis of GC and identifying novel therapeutic targets,as well as useful biomarkers.In this review,we will summarize the recent advances in the understanding of the molecular pathogenesis of GC,focusing on the potential use of these genetic and epigenetic alterations as diagnostic biomarkers and novel therapeutic targets. | Hiroyuki Yamamoto Yoshiyuki Watanabe Tadateru Maehata Ryo Morita Yoshihito Yoshida Ritsuko Oikawa Shinya Ishigooka Shun-ichiro Ozawa Yasumasa Matsuo Kosuke Hosoya Masaki Yamashita Hiroaki Taniguchi Katsuhiko Nosho Hiromu Suzuki Hiroshi Yasuda Yasuhisa Shinomura Fumio Itoh | 2014 | World Journal of Gastroenterology2014，20，14： | 12 |

| 14 | Evaluation of magnifying colonoscopy in the diagnosis of serrated polyps显示文摘AIM:To elucidate the colonoscopic features of serrated lesions of the colorectum using magnifying colonoscopy.METHODS:Broad division of serrated lesions of the colorectum into hyperplastic polyps(HPs),traditional serrated adenomas(TSAs),and sessile serrated adenomas/polyps(SSA/Ps) has been proposed on the basis of recent molecular biological studies.However,few reports have examined the colonoscopic features of these divisions,including magnified colonoscopic findings.This study examined 118 lesions excised in our hospital as suspected serrated lesions after magnified observation between January 2008 and September 2011.Patient characteristics(sex,age),conventional colonoscopic findings(location,size,morphology,color,mucin) and magnified colonoscopic findings(pit pattern diagnosis) were interpreted by five colonoscopists with experience in over 1000 colonoscopies,and were compared with histopathological diagnoses.The pit patterns were categorized according to Kudo's classification,but a more detailed investigation was also performed using the subclassification [type Ⅱ-Open(type Ⅱ-O),type Ⅱ-Long(type Ⅱ-L),or type Ⅳ-Serrated(type Ⅳ-S)] proposed by Kimura T and Yamano H.RESULTS:Lesions comprised 23 HPs(23/118:19.5%),39 TSAs(39/118:33.1%:with cancer in one case),50 SSA/Ps(50/118:42.4%:complicated with cancer in three cases),and six others(6/118:5.1%).We excluded six others,including three regular adenomas,one hamartoma,one inflammatory polyp,and one juvenile polyp for further analysis.Conventional colonoscopy showed that SSA/Ps were characterized as larger in diameter than TSAs and HPs(SSA/P vs HP,13.62 ± 8.62 mm vs 7.74 ± 3.24 mm,P < 0.001;SSA/Ps vs TSA,13.62 ± 8.62 mm vs 9.89 ± 5.73 mm,P < 0.01);common in the right side of the colon [HPs,30.4%(7/23):TSAs,20.5%(8/39):SSA/P,84.0%(42/50),P < 0.001];flat-elevated lesion [HPs,30.4%(7/23):TSAs,5.1%(2/39):SSA/Ps,90.0%(45/50),P < 0.001];normal-colored or pale imucosa [HPs,34.8%(8/23):TSAs,10.3%(4/39):SSA/Ps,80%(40/50),P < 0.001];and with large amounts of mucin [HPs,21.7%(5/23):TSAs,17.9%(7/39):SSA/Ps,72.0%(36/50),P < 0.001].In magnified colonoscopic findings,17 lesions showed either type Ⅱ pit pattern alone or partial type Ⅱ pit pattern as the basic architecture,with 14 HPs(14/17,70.0%) and 3 SSA/Ps.Magnified colonoscopy showed the type Ⅱ-O pit pattern as characteristic of SSA/Ps [sensitivity 83.7%(41/49),specificity 85.7%(54/63)].Cancer was also present in three lesions,in all of which a type Ⅵ pit pattern was also present within the same lesion.There were four HPs and four TSAs each.The type Ⅳ-S pit pattern was characteristic of TSAs [sensitivity 96.7%(30/31),specificity 89.9%(72/81)].Cancer was present in one lesion,in which a type Ⅵ pit pattern was also present within the same lesion.In our study,serrated lesions of the colorectum also possessed the features described in previous reports of conventional colonoscopic findings.The pit pattern diagnosis using magnifying colonoscopy,particularly magnified colonoscopic findings using subclassifications of surface architecture,reflected the pathological characteristics of SSA/Ps and TSAs,and will be useful for colonoscopic diagnosis.CONCLUSION:We suggest that this system could be a good diagnostic tool for SSA/Ps using magnifying colonoscopy. | Shinya Ishigooka Masahito Nomoto Nobuyuki Obinata Yoshichika Oishi Yoshinori Sato Satoko Nakatsu Midori Suzuki Yoshiko Ikeda Tadateru Maehata Tomoaki Kimura Yoshiyuki Watanabe Takashi Nakajima Hiro-o Yamano Hiroshi Yasuda Fumio Itoh | 2012 | World Journal of Gastroenterology2012，18，32： | 11 |

| 17 | Gastric calcifying fibrous tumor removed by endoscopic submucosal dissection显示文摘The World Health Organization describes calcifying fibrous tumors(CFTs) as rare, benign lesions characterized by hypocellular, densely hyalinized collagenization with lymphoplasmacytic infiltration. These tumors rarely involve the gastrointestinal(GI) tract. A routine endoscopic upper gastrointestinal screen detected a 10-mm submucosal tumor(SMT) in the lesser curvature of the lower corpus of the stomach of an apparently healthy, 37-year-old woman with no history of Helicobacter pylori infection. Endoscopic ultrasonography(EUS) localized the internally isoechoic, homogeneous SMT mainly within the submucosa. Malignancy was ruled out using endoscopic submucosal dissection(ESD). A pathological examination confirmed complete resection of the SMT, and defined a hypocellular, spindle-cell tumor with a densely hyalinized, collagenous matrix, scattered lymphoplasmacytic aggregates as well as a few psammomatous, dystrophic calcified foci. The mass was immunohistochemically positive for vimentin and negative for CD117(c-kit protein), CD34, desmin, smooth muscle actin(SMA) and S100. Therefore, the histological findings were characteristic of a CFT. To date, CFT resection by ESD has not been described. This is the first case report of a gastric calcifying fibrous tumor being completely resected by ESD after endoscopic ultrasonography. | Naotaka Ogasawara Shinya Izawa Mari Mizuno Atsushi Tanabe Tomonori Ozeki Hisatsugu Noda Emiko Takahashi Makoto Sasaki Toyoharu Yokoi Kunio Kasugai | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，9： | 8 |
| 18 | Stratifying the risk of lymph node metastasis in undifferentiated-type early gastric cancer显示文摘AIM:To study how lymph node metastasis(LNM) risk is stratified in undifferentiated-type early gastric cancer(undiff-EGC) dependent on combinations of risk factors.METHODS:Five hundred and sixty-seven cases with undiff-EGC undergoing gastrectomy with lymphadenectomy were examined retrospectively.Using clinicopathological factors of patient age,location,size,an endoscopic macroscopic tumor form,ulceration,depth,histology,lymphatic involvement(LI) and venous involvement(VI),LNM risk was examined and stratified by conventional statistical analysis and datamining analysis.RESULTS:LNM was positive in 44 of 567 cases(7.8%).Univariate analysis revealed > 2 cm,protrusion,submucosal(sm),mixed type,LI and VI as significant prognostic factors and > 2 cm and LI-positive were independent factors by multivariate analysis.In preoperatively evaluable factors excluding LVI,sm and > 2 cm were independent factors.According to the depth and size,cases were categorized into the low-risk group [m and ≤ 2 cm,0%(LNM incidence)],the moderaterisk group(m and > 2 cm,5.6%; and sm and ≤ 2 cm,6.0%),and the high-risk group(sm and > 2 cm,19.3%).On the other hand,LNM occurred in 1.4% in all LI-negative cases,greatly lower than 28.2% in all LI-positive cases,and LNM incidence was low in LInegative cases even in the moderate- and high-risk groups.CONCLUSION:LNM-related factors in undiff-EGC were depth and size preoperatively while those were LI and size postoperatively.Among these factors,LI was the most significantly correlated factor. | Yukiko Asakawa Masahiko Ohtaka Shinya Maekawa Mitsuharu Fukasawa Yasuhiro Nakayama Tatsuya Yamaguchi Taisuke Inoue Tomoyoshi Uetake Minoru Sakamoto Tadashi Sato Yoshihiko Kawaguchi Hideki Fujii Kunio Mochizuki Masao Hada Toshio Oyama Tomotaka Yasumura Kosaku Omata Atsushi Nishiyama Keiichi Naito Hideo Hata Yoshiaki Haba Kazuyuki Miyata Haruhisa Saitoh Yoichi Yamadera Kazuo Miura Akira Kawaoi Tohru Abe Hajime Tsunoda Yuji Honda Masayuki Kurosaki Nobuyuki Enomoto | 2015 | World Journal of Gastroenterology2015，21，9： | 8 |
| 19 | Can mosapride citrate reduce the volume of lavage solution for colonoscopy preparation?显示文摘AIM:To evaluate the possibility of reducing the volume of polyethylene glycol(PEG)-electrolyte solution using adjunctive mosapride citrate for colonoscopy preparation. METHODS:This was a single-center,prospective, randomized,investigator-blinded,non-inferiority study involving 252 patients of both sexes,aged from 20 to 80 years,scheduled for screening or diagnostic colonoscopy in our department.A total of 126 patients was randomized to receive 1.5 L PEG-electrolyte solution plus 15 mg of mosapride(1.5 L group),and 126 received 2 L PEG-electrolyte solution plus 15 mg of mosapride(2 L group).Patients completed a questionnaire on the acceptability and tolerability of the bowel preparation process.The efficacy of bowel preparation was assessed using a 5-point scale based on the Aronchick scale.The primary end point was adequate bowel preparation rates(score of excellent/good/fair) vs(poor/inadequate).Acceptability and tolerability,as well as disease detection,were secondary end points. RESULTS:A total of 244 patients was included in the analysis.There were no significant differences between the 2 L and 1.5 L groups in age,sex,body mass index, number of previous colonoscopies,and the preparation method used previously.The adequate bowel preparation rates were 88.5%in the 2 L group and 82.8%in the 1.5 L group[95%lower confidence limit(LCL)for the difference=-14.5%,non-inferiority P=0.019]in the right colon.In the left colon,the adequate bowel preparation rates were 89.3%in the 2 L group and 81.1%in the 1.5 L group(95%LCL=-17.0%,non-inferiority P=0.066).Compliance,defined as complete (100%)intake of the PEG solution,was significantly higher in the 1.5 L group than in the 2 L group(96.8% vs 85.7%,P=0.002).The proportion of abdominal distension(none/mild/moderate/severe)was significantly lower in the 1.5 L group than in the 2 L group (36/65/22/3 vs 58/48/18/2,P=0.040).Within the subgroup who had undergone colonoscopy previously, a significantly higher number of patients in the 1.5 L group than in the 2 L group felt that the current preparation was easier than the previous one(54.1%vs 28.0%,P=0.001).The disease detection rate was not significantly different between the two groups. CONCLUSION:Although the 1.5 L group had better acceptability and tolerability,15 mg of mosapride may be insufficient to compensate for a 0.5-L reduction of PEG solution. | Masahiro Tajika Yasumasa Niwa Vikram Bhatia Shinya Kondo Tsutomu Tanaka Nobumasa Mizuno Kazuo Hara Susumu Hijioka Hiroshi Imaoka Koji Komori Kenji Yamao | 2013 | World Journal of Gastroenterology2013，19，5： | 8 |
