1BRIEF ARTICLE New reduced volume preparation regimen in colon capsule endoscopy显示文摘AIM:To evaluate the effectiveness of our proposed bowel preparation method for colon capsule endoscopy.METHODS:A pilot,multicenter,randomized controlled trial compared our proposed 'reduced volume method'(group A) with the 'conventional volume method'(group B) preparation regimens.Group A did not drink polyethylene glycol electrolyte lavage solution(PEGELS) the day before the capsule procedure,while group B drank 2 L.During the procedure day,groups A and B drank 2 L and 1 L of PEG-ELS,respectively,and swallowed the colon capsule(PillCam COLON capsule).Two hours later the first booster of 100 g magnesium citrate mixed with 900 mL water was administered to both groups,and the second booster was administered six hours post capsule ingestion as long as the capsule had not been excreted by that time.Capsule videos were reviewed for grading of cleansing level,RESULTS:Sixty-four subjects were enrolled,with results from 60 analyzed.Groups A and B included 31 and 29 subjects,respectively.Twenty-nine(94%) subjects in group A and 25(86%) subjects in group B had adequate bowel preparation(ns).Twenty-two(71%) of the 31 subjects in group A excreted the capsule within its battery life compared to 16(55%) of the 29 subjects in group B(ns).Of the remaining 22 subjects whose capsules were not excreted within the battery life,all of the capsules reached the left side colon before they stopped functioning.A single adverse event was reported in one subject who had mild symptoms of nausea and vomiting one hour after starting to drink PEG-ELS,due to ingesting the PEG-ELS faster than recommended.CONCLUSION:Our proposed reduced volume bowel preparation method for colon capsule without PEG-ELS during the days before the procedure was as effective as the conventional volume method.Yasuo Kakugawa Yutaka Saito Shoichi Saito Kenji Watanabe Naoki Ohmiya Mitsuyuki Murano Shiro Oka Tetsuo Arakawa Hidemi Goto Kazuhide Higuchi Shinji Tanaka Hideki Ishikawa Hisao Tajiri 2012World Journal of Gastroenterology2012,18,17:8
2Characteristics of symptomatic reflux episodes in Japanese proton pump inhibitor-refractory non-erosive reflux disease patients显示文摘AIM: To clarify the pathogenesis of gastroesophageal reflux disease symptoms in non-erosive reflux disease(NERD) patients.METHODS: Thirty-five NERD patients with persistent symptoms, despite taking rabeprazole 10 mg twice daily for at least 8 wk, were included in this study. All patients underwent 24 h combined impedance- p H on rabeprazole. The symptom index(SI) was considered to be positive if ≥ 50%, and proximal reflux episodes were determined when reflux reached 15 cm above the proximal margin of the lower esophageal sphincter.RESULTS: In 14(40%) SI-positive patients, with liquid weakly acid reflux, the occurrence rate of reflux symptoms was significantly more frequent in proximal reflux episodes(46.7%) than in distal ones(5.7%)(P < 0.001). With liquid acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes(38.5%) and distal ones(20.5%)(NS). With mixed liquid-gas weakly acid reflux, the occurrence rate of reflux symptoms in proximal reflux episodes was significantly more frequent(31.0%) than in distal reflux ones(3.3%)(P < 0.001). With mixed liquid-gas acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes(29.4%) and distal ones(14.3%)(NS).CONCLUSION: The proximal extent of weakly acidic liquid and mixed liquid-gas reflux is a major factor associated with reflux perception in SI-positive patients on proton pump inhibitor therapy.Kenichiro Nakagawa Tomoyuki Koike Katsunori Iijima Masahiro Saito Hiroki Kikuchi Waku Hatta Nobuyuki Ara Kaname Uno Naoki Asano Tooru Shimosegawa 2015World Journal of Gastroenterology2015,21,47:4
3Performance of 18-fluoro-2-deoxyglucose positron emission tomography for esophageal cancer screening显示文摘AIM To evaluate the performance of 18-fluoro-2-deoxyglucose positron emission tomography(FDG-PET) for esophageal cancer(EC) screening.METHODS We retrospectively analyzed the data of consecutive asymptomatic individuals who underwent FDG-PET and esophagogastroduodenoscopy(EGD) simultaneously for cancer screening at our institution from February 2004 to March 2013. In total, 14790 FDG-PET and EGD procedures performed for 8468 individuals were included in this study, and the performance of FDGPET for EC screening was assessed by comparing the results of FDG-PET and EGD, considering the latter as the reference.RESULTS Thirty-two EC lesions were detected in 28 individuals(31 squamous cell carcinomas and 1 adenocarcinoma). The median tumor size was 12.5 mm, and the depths of the lesions were as follows: Tis(n = 12), T1a(n = 15), and T1b(n = 5). Among the 14790 FDG-PET procedures, 51 examinations(0.3%) showed positive findings in the esophagus; only 1 was a true-positive finding. The screen sensitivity, specificity, positive predictive value, and negative predictive value of FDGPET for ECs were 3.6%(95%CI: 0.1-18.3), 99.7%(95%CI: 99.6-99.7), 2.0%(95%CI: 0.0-10.4), and 99.8%(95%CI: 99.7-99.9), respectively. Of the 50 FDG-PET false-positive cases, 31 were observed in the lower esophagus, and gastroesophageal reflux disease was observed in 17 of these 31 cases.CONCLUSION This study is the first to clarify the FDG-PET performance for EC screening. Based on the low screen sensitivity, FDG-PET is considered to be difficult to use as a screening modality for ECs.Masau Sekiguchi Takashi Terauchi Yasuo Kakugawa Naoki Shimada Yutaka Saito Takahisa Matsuda 2017World Journal of Gastroenterology2017,23,15:3
