Clinically, we suspected a Guillain-Barr\u00e9 variant. However, her functioning continued to decline despite intravenous immunoglobulin therapy, and she had normal spinal imaging studies and CSF analysis. Of note, she had a subtotal oesophagectomy and proximal gastrectomy 20 months previously for oesophageal cancer. We found her to be deficient in vitamin D, vitamin E and copper. She was treated with nutritional supplementation of these vitamins and infusion of trace elements, resulting in a gradual improvement in lower limb power, sensation and coordination, as well as improved cognition and mentation. Monthly outpatient neurology follow-up shows continued improvement in symptoms and return towards baseline functioning with regular infusions of nutritional elements and monitoring of blood levels.<\/jats:p>","DOI":"10.1136\/bcr-2021-242716","type":"journal-article","created":{"date-parts":[[2021,5,26]],"date-time":"2021-05-26T14:35:47Z","timestamp":1622039747000},"page":"e242716","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Nutritional neuropathy postoesophagogastrectomy"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3198-1257","authenticated-orcid":false,"given":"Paul","family":"Ryan","sequence":"first","affiliation":[{"name":"Anaesthesia\/Intensive Care, Tallaght University Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Kinirons","sequence":"additional","affiliation":[{"name":"Neurology, Bon Secours Hospital Hospital Cork, Cork, Munster, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,5,26]]},"reference":[{"key":"2025082712041927000_14.5.e242716.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ncl.2009.09.006"},{"key":"2025082712041927000_14.5.e242716.2","doi-asserted-by":"crossref","first-page":"477","DOI":"10.1016\/j.ncl.2013.02.002","article-title":"Nutritional neuropathies","volume":"31","author":"Hammond","year":"2013","journal-title":"Neurol Clin"},{"key":"2025082712041927000_14.5.e242716.3","doi-asserted-by":"publisher","DOI":"10.1212\/01.WNL.0000132644.52613.FA"},{"key":"2025082712041927000_14.5.e242716.4","doi-asserted-by":"crossref","DOI":"10.1212\/01.CON.0000455880.06675.5a","article-title":"Peripheral neuropathy due to vitamin deficiency, toxins, and medications","volume":"20","author":"Staff","year":"2014","journal-title":"Continuum"},{"key":"2025082712041927000_14.5.e242716.5","doi-asserted-by":"crossref","first-page":"2074","DOI":"10.1056\/NEJMoa1112088","article-title":"Preoperative chemoradiotherapy for esophageal or junctional cancer","volume":"366","author":"van Hagen","year":"2012","journal-title":"N Engl J Med Overseas Ed"},{"key":"2025082712041927000_14.5.e242716.6","doi-asserted-by":"publisher","DOI":"10.1381\/096089206778026415"},{"key":"2025082712041927000_14.5.e242716.7","unstructured":"Fauci AS .
