No reports appear to have assessed the serum copper state of patients following gastrectomy with RY reconstruction for gastric cancer. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; A cross-sectional study was conducted from June 2013 to December 2014. Serum copper levels (SCLs) in 242 out-clinic patients who underwent curative gastrectomy were obtained. Patients were classified into an RY group (n = 208) and a non-RY group (n = 34). &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Hypocupremia was identified in 3 patients in the RY group (1.4%), and 2 patients in the non-RY group (5.9%; p = 0.146), but none experienced any symptoms caused by hypocupremia. No significant difference in the mean SCL was seen between the RY group (105.8 \u00b1 21.2 \u00b5g\/dl) and non-RY group (107.9 \u00b1 22.7 \u00b5g\/dl; p = 0.499). In the RY group, the mean SCL was significantly lower in younger patients, patients with follow-up period &lt;3 years, and male patients. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Some patients developed hypocupremia after gastrectomy with RY reconstruction, but the number is acceptably low, and physical symptoms were unusual.<\/jats:p>","DOI":"10.1159\/000431186","type":"journal-article","created":{"date-parts":[[2015,6,30]],"date-time":"2015-06-30T21:01:29Z","timestamp":1435698089000},"page":"301-305","source":"Crossref","is-referenced-by-count":7,"title":["Assessment of Serum Copper State after Gastrectomy with Roux-en-Y Reconstruction for Gastric Cancer"],"prefix":"10.1159","volume":"32","author":[{"given":"Masatoshi","family":"Nakagawa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuyuki","family":"Kojima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikito","family":"Inokuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keiji","family":"Kato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirofumi","family":"Sugita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sho","family":"Otsuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyoko","family":"Higuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenta","family":"Kobayashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichi","family":"Sugihara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2015,7,1]]},"container-title":["Digestive Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/431186","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/431186","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:11:19Z","timestamp":1745431879000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000431186"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2015,8,1]]},"published-print":{"date-parts":[[2015,8,18]]}},"URL":"https:\/\/doi.org\/10.1159\/000431186","archive":["Portico"],"relation":{},"ISSN":["0253-4886","1421-9883"],"issn-type":[{"type":"print","value":"0253-4886"},{"type":"electronic","value":"1421-9883"}],"subject":[],"published":{"date-parts":[[2015]]}}}
