The possibility that POEM could reduce the risk of developing esophageal squamous cell carcinoma was evaluated.Methods: This was a single-centre, retrospective study. Fifteen consecutive patients with esophageal achalasia who underwent POEM in our institution between August 2010 and January 2012 were enrolled. Ultra-high magnification with endocytoscopy was performed, and both histopathological and immunohistochemical evaluations for Ki-67 and p53 were assessed before and 3 months after POEM.Results: POEM was successfully performed and effectively released the dysphagia symptom in all patients without severe complications. Subjective symptoms (mean Ekcardt score, before 7.4 vs. after 0.5, p<0.05) and manometric pressure studies (mean lower esophageal sphincter pressure), before 82.7 vs. after 22.9 mmHg, p<0.05) showed substantial improvement following POEM. The average numbers of esophageal epithelial nuclei before and after POEM on endocytoscopic images were 128.0 and 78.0, respectively (p<0.05). The mean Ki-67-positive ratio was 26.0 (median 25.4, range, 10.3-33.2) before and 20.7 (median 20.0, 13.1-29.9; p=0.07) after POEM, and the mean p53-positive ratio was 2.35 (median 2.61, 0.32-4.23) before and 0.97 (median 1.49, 0.32-1.56; p<0.05) after POEM. A significant positive correlation was seen between the number of nuclei and the Ki-67-positive ratio (p<0.05).Conclusions: POEM appears to be an effective and less invasive treatment of choice against achalasia and may reduce the risk of esophageal carcinogenesis. Endocytoscopy can be useful for the assessment of esophageal cellular proliferation.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"BMC Gastroenterology, 13(1), 22; 2013","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"BioMed Central"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1186/1471-230X-13-22","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2013 Minami et al.; licensee BioMed Central Ltd."},{"subitem_rights":"This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/2.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited."}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1471230X","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Minami, Hitomi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Naoyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsushima, Kayoko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akazawa, Yuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohnita, Ken"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeshima, Fuminao"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakayama, Toshiyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hayashi, Tomayoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Haruhiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakao, Kazuhiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Isomoto, Hajime"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"BMCGas13_22.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BMCGas13_22.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/8700/files/BMCGas13_22.pdf"},"version_id":"c0a783dc-e283-4e83-83de-8c7d80978b42"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Esophageal achalasia","subitem_subject_scheme":"Other"},{"subitem_subject":"Esophageal cancer","subitem_subject_scheme":"Other"},{"subitem_subject":"Per-oral endoscopic myotomy","subitem_subject_scheme":"Other"},{"subitem_subject":"POEM","subitem_subject_scheme":"Other"},{"subitem_subject":"Squamous cell carcinoma","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Improvement of endocytoscopic findings after per oral endoscopic myotomy (POEM) in esophageal achalasia; does POEM reduce the risk of developing esophageal carcinoma?
