This study aimed to use dual bioelectrical impedance analysis (BIA) to determine the change in bodyweight and body composition in patients with achalasia before and after peroral endoscopic myotomy (POEM). Methods: Patients with achalasia who underwent POEM from 2013 to 2018 (n = 72) were retrospectively analyzed for change in bodyweight before and after 3 months. Additionally, change in body composition was prospectively investigated in the final 10 of 72 patients using non-radiation dual BIA. Results: Twenty patients (27.8%) were underweight (body mass index < 18.5) before undergoing POEM. No clinical parameters were identified to be associated with the underweight condition before POEM and be predictive of an increase in bodyweight after POEM. Low visceral fat volume observed on dual BIA correlated closely with the result obtained using computed tomography (Pearson correlation coefficient: r = 0.850, P < 0.01). Patients with achalasia had a statistically significant increase in visceral (P < 0.01) and subcutaneous fat volumes (P < 0.01) after POEM. Skeletal muscle mass index slightly increased (P = 0.02), although the value after POEM was still low. No blood biomarkers were indicators for low bodyweight or low visceral fat volume. Conclusions: Dual BIA is an effective non-invasive tool to evaluate the change in body composition of underweight patients with achalasia. Skeletal muscle volume was not enough after POEM, although a rapid increase in the intra-abdominal fat volume was observed. Additional studies are warranted to understand the pathological implications.","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Journal of Gastroenterology and Hepatology. 2020, 35(4), 601-608.","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博(医)甲第915号","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"13101甲第4681号"}]},"item_6_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"178012","nameIdentifierScheme":"WEKO"}],"names":[{"name":"水澤, 健"}]}]},"item_6_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1111/jgh.14847","subitem_relation_type_select":"DOI"}}]},"item_6_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"【○!C】 2019 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd"}]},"item_6_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"ETD"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Mizusawa, Takeshi"}],"nameIdentifiers":[{"nameIdentifier":"178011","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-08-31"}],"displaytype":"detail","filename":"r1nmk915_a.pdf","filesize":[{"value":"571.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","url":"https://niigata-u.repo.nii.ac.jp/record/34006/files/r1nmk915_a.pdf"},"version_id":"cb3ca802-e5b8-4432-a608-5aa7a1a2db0d"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-25"}],"displaytype":"detail","filename":"r1nmk915.pdf","filesize":[{"value":"18.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://niigata-u.repo.nii.ac.jp/record/34006/files/r1nmk915.pdf"},"version_id":"14af60eb-8f2b-479c-901b-fabb363e9429"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"abdominal fat","subitem_subject_scheme":"Other"},{"subitem_subject":"achalasia","subitem_subject_scheme":"Other"},{"subitem_subject":"bioelectrical impedance","subitem_subject_scheme":"Other"},{"subitem_subject":"peroral endoscopic myotomy","subitem_subject_scheme":"Other"},{"subitem_subject":"skeletal muscle","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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Change in body composition in patients with achalasia before and after peroral endoscopic myotomy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Change in body composition in patients with achalasia before and after peroral endoscopic myotomy"}]},"item_type_id":"6","owner":"1","path":["455","562"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-08-31"},"publish_date":"2020-08-31","publish_status":"0","recid":"34006","relation_version_is_last":true,"title":["Change in body composition in patients with achalasia before and after peroral endoscopic myotomy"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T04:01:51.797253+00:00"}
